技术领域technical field
本发明总地涉及木材加工技术领域，更具体地涉及一种集装箱底板和制作方法。The present invention generally relates to the technical field of wood processing, and more specifically relates to a container bottom plate and a manufacturing method.
背景技术Background technique
集装箱的主要承载面积是底板，集装箱制造业要求底板具有很高的力学性能、外观质量、抗冲击性和耐老化性能。现有的集装箱底板包括全木质的集装箱底板和竹木复合集装箱底板。全木的集装箱底板需要消耗大量的硬质木材，硬质木材的生长周期长，大量的砍伐对环境造成了非常恶劣的影响。随着人类对环境保护的日益重视，木质的集装箱底板慢慢在退出市场，由竹木复合集装箱底板来进行取代。The main load-bearing area of a container is the bottom plate. The container manufacturing industry requires the bottom plate to have high mechanical properties, appearance quality, impact resistance and aging resistance. Existing container bottoms include all-wood container bottoms and bamboo-wood composite container bottoms. The all-wood container floor needs to consume a large amount of hard wood. The growth cycle of hard wood is long, and a large amount of felling has caused a very bad impact on the environment. As human beings pay more and more attention to environmental protection, the wooden container floor is slowly withdrawing from the market and replaced by bamboo-wood composite container floor.
传统的竹木复合集装箱底板由一层竹帘一层木单板复合而成，竹帘可以由多个竹条制成，其生产工艺需要对竹帘进行以下处理：湿竹帘先烘干，然后用低固体含量的酚醛树脂浸胶，再烘干。但这种制造工艺存在以下方面的缺陷：The traditional bamboo-wood composite container floor is composed of a layer of bamboo curtain and a layer of wood veneer. The bamboo curtain can be made of multiple bamboo strips. The production process requires the following treatment of the bamboo curtain: the wet bamboo curtain is dried first, It is then impregnated with a low solids phenolic resin and dried. However, this manufacturing process has the following disadvantages:
一、因为竹帘浸胶后需要将附着在竹帘表面的胶水滴干再拿去烘干，但是滴胶完全是靠重力的作用往下流，而且竹帘装在浸胶笼中压得很紧，所以越到下端胶越滴不干，造成上端胶量小，下端胶量大，因此，竹帘施胶不均匀。1. After the bamboo curtain is dipped in glue, the glue attached to the surface of the bamboo curtain needs to be dripped dry and then dried, but the glue is completely flowed down by the action of gravity, and the bamboo curtain is installed in the dipping cage and pressed very tightly. , so the more the glue drops to the lower end, the more it will not dry, resulting in a small amount of glue at the upper end and a larger amount of glue at the lower end. Therefore, the glue applied to the bamboo curtain is uneven.
进一步地，上述制造工艺还会造成烘干后含水率不均匀，胶量大的含水率高，胶量小的含水率低。烘干竹帘的温度和竹帘的最终含水率不易控制，竹龄及竹篾(竹条)粗糙程度和竹篾厚度都会影响吸水量，竹龄短、表面粗糙、竹篾厚的竹帘吸水多，难以烘干。含水率不均匀会对集装箱底板的强度和变形产生影响。烘得太干或温度太高会造成酚醛树脂预固化，最终影响到胶合强度，造成质量不稳定。Furthermore, the above-mentioned manufacturing process will also result in uneven moisture content after drying, high moisture content for a large amount of glue, and low moisture content for a small amount of glue. The temperature of drying bamboo curtains and the final moisture content of bamboo curtains are not easy to control. The age of bamboo, the roughness of bamboo strips (bamboo strips) and the thickness of bamboo strips will all affect the water absorption. Bamboo curtains with short bamboo age, rough surface and thick bamboo strips absorb water. Much, it is difficult to dry. Uneven moisture content will affect the strength and deformation of the container floor. Too dry or too high temperature will cause pre-curing of phenolic resin, which will eventually affect the bonding strength and cause unstable quality.
二、采用上述竹帘处理工艺制备的竹木复合集装箱底板仍是由一层竹帘一层木单板交替复合而成，使得该集装箱底板的制备仍需要消耗大量的木材，竹帘只替代了全木集装箱底板其中少量的木材。2. The bamboo-wood composite container floor prepared by the above-mentioned bamboo curtain treatment process is still composed of one layer of bamboo curtain and one layer of wood veneer alternately, so that the preparation of the container floor still needs to consume a large amount of wood, and the bamboo curtain only replaces A small amount of wood in the bottom of the all-wood container.
因此，需要提供一种集装箱底板和制作方法，以至少部分地解决上述问题。Therefore, there is a need to provide a container floor and a manufacturing method to at least partially solve the above-mentioned problems.

为了使得集装箱底板具有良好的抗震、耐冲击、耐气候、耐老化等性能，如图1所示，本发明提供一种集装箱底板100，集装箱底板100可以由多个竹条132和木单板复合热压成型，并且集装箱底板100的强度大且板面平整。In order to make the container bottom plate have good performances such as shock resistance, impact resistance, weather resistance, and aging resistance, as shown in Figure 1, the present invention provides a container bottom plate 100, which can be composed of a plurality of bamboo strips 132 and wood veneers It is formed by thermocompression, and the container bottom plate 100 has high strength and flat surface.
具体地，集装箱底板100包括面层110、芯层130和底层120，面层110、芯层130和底层120沿集装箱底板100的厚度方向D1由上至下布置。在页面中，为了页面的简洁，虽然“集装箱底板100的厚度方向D1”的箭头指向的是页面的上方，但“集装箱底板100的厚度方向D1”的箭头也可以指向页面的下方。Specifically, the container floor 100 includes a surface layer 110 , a core layer 130 and a bottom layer 120 , and the surface layer 110 , the core layer 130 and the bottom layer 120 are arranged from top to bottom along the thickness direction D1 of the container floor 100 . On the page, for the sake of simplicity, although the arrow "thickness direction D1 of the container floor 100" points to the top of the page, the arrow "thickness direction D1 of the container floor 100" can also point to the bottom of the page.
芯层130包括基板131，基板131由多个竹条132制成，多个竹条132沿侧向依次贴合且拼接在一起。竹条132的厚度方向D2与集装箱底板100的厚度方向D1相垂直。在页面中，为了页面的简洁，虽然“竹条132的厚度方向D2”的箭头指向的是页面的右侧，但“集装箱底板100的厚度方向D1”的箭头也可以指向页面的左侧。The core layer 130 includes a base plate 131, the base plate 131 is made of a plurality of bamboo strips 132, and the plurality of bamboo strips 132 are sequentially pasted and spliced together along the lateral direction. The thickness direction D2 of the bamboo strips 132 is perpendicular to the thickness direction D1 of the container floor 100 . On the page, for the sake of brevity, although the arrow "thickness direction D2 of the bamboo strip 132" points to the right side of the page, the arrow "thickness direction D1 of the container floor 100" can also point to the left side of the page.
竹条132的沿竹条132的厚度方向D2具有相反的两个侧面，相邻的竹条132的彼此相对的侧面可以彼此贴合，也就是说，多个竹条132可以沿竹条132的厚度方向D2依次贴合且拼接在一起。The bamboo strip 132 has two opposite sides along the thickness direction D2 of the bamboo strip 132, and the sides opposite to each other of adjacent bamboo strips 132 can be attached to each other, that is to say, a plurality of bamboo strips 132 can be along the direction of the bamboo strip 132. The thickness direction D2 is sequentially pasted and spliced together.
竹条132的长度方向为垂直于页面的方向，竹条132的宽度方向与集装箱底板100的厚度方向D1大致平行。在加工过程中，每一个竹条132沿竹条132的宽度方向的尺寸相同，这样，每个竹条132沿集装箱底板100的厚度方向D1的尺寸可以均相同，从而保证多个竹条132的上表面均齐平，多个竹条132的下表面均齐平，从而保证集装箱底板100的平整度。The length direction of the bamboo strips 132 is perpendicular to the page, and the width direction of the bamboo strips 132 is roughly parallel to the thickness direction D1 of the container floor 100 . During processing, each bamboo strip 132 has the same size along the width direction of the bamboo strip 132, like this, the size of each bamboo strip 132 along the thickness direction D1 of the container bottom plate 100 can be all the same, thereby ensuring the plurality of bamboo strips 132 The upper surfaces are all flush, and the lower surfaces of the plurality of bamboo strips 132 are all flush, so as to ensure the flatness of the container floor 100 .
根据本发明的集装箱底板100，多个竹条132沿侧向依次贴合且拼接在一起，并且竹条132的厚度方向D2与集装箱底板100的厚度方向D1相垂直。这样，多个竹条132沿集装箱底板100的厚度方向D1的上表面相互齐平，多个竹条132沿集装箱底板100的厚度方向D1的下表面相互齐平。无论竹条132上是否涂覆有胶水并且无论涂覆的胶水的胶含量的多少，均不会使得多个竹条132之间沿集装箱底板100的厚度方向D1产生高度差，操作简单，降低胶耗，进而保证集装箱底板100的板面平整。According to the container bottom plate 100 of the present invention, a plurality of bamboo strips 132 are laminated and spliced together in sequence along the lateral direction, and the thickness direction D2 of the bamboo strips 132 is perpendicular to the thickness direction D1 of the container bottom plate 100 . In this way, the upper surfaces of the plurality of bamboo strips 132 along the thickness direction D1 of the container bottom plate 100 are flush with each other, and the lower surfaces of the plurality of bamboo strips 132 along the thickness direction D1 of the container bottom plate 100 are flush with each other. Regardless of whether the bamboo strips 132 are coated with glue and regardless of the glue content of the coated glue, there will not be a height difference between the plurality of bamboo strips 132 along the thickness direction D1 of the container floor 100, the operation is simple, and the glue is reduced. consumption, thereby ensuring that the surface of the container floor 100 is flat.
多个竹条132沿侧向依次贴合且拼接在一起以形成一层基板131。竹条132的沿集装箱底板100的厚度方向D1的尺寸可以近似等于集装箱底板100的沿集装箱底板100的尺寸，本发明的集装箱底板100不需要一层竹帘一层木单板的结构模式，只需少量地使用木单板，降低了木材的使用量。竹条132的纹理方向与水平方向大致平行，集装箱底板100强度依靠多个竹条132提供，多个竹条132的沿竹条132的宽度方向的强度提供了集装箱底板100的强度。由于集装箱底板100沿集装箱底板100的厚度方向D1的竹条132为一体结构，多个竹条132不沿集装箱底板100的厚度方向D1叠放，既保证了集装箱底板100的板面的平整，又提高了集装箱底板100的强度，多个竹条132可以替代大量的木单板，减少木单板的使用量，减少木材的消耗。A plurality of bamboo strips 132 are sequentially laminated and spliced together along the lateral direction to form a layer of substrate 131 . The size of the bamboo bar 132 along the thickness direction D1 of the container bottom plate 100 can be approximately equal to the size of the container bottom plate 100 along the container bottom plate 100. The container bottom plate 100 of the present invention does not need a structural model of one layer of bamboo curtains and one layer of wood veneer. A small amount of wood veneer needs to be used, which reduces the amount of wood used. The grain direction of the bamboo strips 132 is roughly parallel to the horizontal direction. The strength of the container bottom plate 100 is provided by the plurality of bamboo strips 132 . Because the container bottom plate 100 has an integrated structure along the bamboo strips 132 along the thickness direction D1 of the container bottom plate 100, a plurality of bamboo strips 132 are not stacked along the thickness direction D1 of the container bottom plate 100, which not only ensures the flatness of the container bottom plate 100, but also The strength of the container floor 100 is improved, and a plurality of bamboo strips 132 can replace a large number of wood veneers, reducing the usage of wood veneers and reducing the consumption of wood.
竹条132可以由竹筒沿竹筒的长度方向开片且去掉竹筒内的节隔制成，这样，能够有效利用本地丰富的、可持续的竹材资源替换现有的竹木复合底板中的大量的木单板。竹筒沿竹筒的长度方向间隔具有多个节隔，可以使用弧形刨将节隔去除。竹条132在与竹条132的厚度方向D2相平行的平面上的截面形状为弧形。由此，弧形的竹条132能够均匀分散集装箱底板100所受的压力，提高集装箱底板100的结构强度，避免集装箱底板100变形。本发明的弧形竹条与现有的竹帘相比，不仅能够提高毛竹利用率而且还能很大程度降低胶耗，降低了生产成本，更好地保护环境，实现经济效益和社会效益双赢。Bamboo strips 132 can be made by splitting the bamboo tube along the length direction of the bamboo tube and removing the knots in the bamboo tube. In this way, the abundant and sustainable bamboo resources in the local area can be effectively used to replace a large amount of wood in the existing bamboo-wood composite floor. veneer. The bamboo tube has multiple intervals along the length direction of the bamboo tube, which can be removed with a curved planer. The cross-sectional shape of the bamboo strip 132 on a plane parallel to the thickness direction D2 of the bamboo strip 132 is an arc. Thus, the arc-shaped bamboo strips 132 can evenly disperse the pressure on the container floor 100 , improve the structural strength of the container floor 100 , and avoid deformation of the container floor 100 . Compared with the existing bamboo curtains, the arc-shaped bamboo strips of the present invention can not only improve the utilization rate of moso bamboo, but also greatly reduce glue consumption, reduce production costs, better protect the environment, and achieve a win-win situation of economic and social benefits .
竹子沿径向从外向内依次为竹青、竹肉和竹黄。由于多个竹条132沿侧向依次贴合且拼接在一起，因此本发明的竹条132不需要去青去黄，多个竹条132便可以连接在一起。“去青”指的是去除竹青，是指从竹材的外表面去除一定厚度的材料，换言之，从竹青一侧去除一定厚度的表层(包括竹青和少量的竹肉)。“去黄”指的是去除竹黄，是指从竹材的内表面去除一定厚度的材料，换言之，从竹黄一侧去除一定厚度的内壁层(包括竹黄和少量的竹肉)。Bamboo is divided into bamboo green, bamboo flesh and bamboo yellow from outside to inside along the radial direction. Since the plurality of bamboo strips 132 are sequentially pasted and spliced together in the lateral direction, the bamboo strips 132 of the present invention do not need to be degreened and yellowed, and the plurality of bamboo strips 132 can be connected together. "Degreening" refers to removing green bamboo, which refers to removing a certain thickness of material from the outer surface of the bamboo, in other words, removing a certain thickness of the surface layer (including green bamboo and a small amount of bamboo meat) from the green side of the bamboo. "Removing yellow" refers to removing bamboo yellow, which refers to removing a certain thickness of material from the inner surface of bamboo, in other words, removing a certain thickness of inner wall layer (including bamboo yellow and a small amount of bamboo meat) from the side of bamboo yellow.
本发明的集装箱底板100不需要用竹篾编织竹帘，毛竹截断开片后用弧形刨简单去掉竹节即可，无需去青去黄，操作简单，极大提高了竹材的利用率。The container bottom plate 100 of the present invention does not need to use bamboo strips to weave bamboo curtains. After the moso bamboo is cut into pieces, the bamboo joints can be simply removed with an arc planer, and there is no need to remove green and yellow. The operation is simple and the utilization rate of bamboo is greatly improved.
进一步地，为了提高集装箱底板100的结构强度，相邻的竹条132粘合在一起。比如，相邻的竹条132的彼此相对的侧面设置有胶水。多个竹条132可以先进行烘干，以降低竹条132的自身的含水量，从而便于对竹条132涂覆胶水。多个竹条132可以浸胶或者刷胶。Further, in order to improve the structural strength of the container floor 100, adjacent bamboo strips 132 are glued together. For example, the opposite sides of adjacent bamboo strips 132 are provided with glue. The plurality of bamboo strips 132 can be dried first to reduce the moisture content of the bamboo strips 132 , so as to facilitate coating the bamboo strips 132 with glue. The plurality of bamboo strips 132 can be dipped or brushed with glue.
竹条132没有去青去黄，吸胶吸水量都很少，浸胶或刷胶均不会吸收多少水分，更容易控制含水率，不需要烘干，不会出现酚醛树脂胶预固化的问题，所生产的集装箱底板100质量更好，强度更高，而且省去了部分工序，降低了能耗和和胶耗，节约生产成本。多个竹条132沿侧向依次贴合且拼接在一起，浸胶或者刷胶后的多个竹条132无需烘干便可以直接进入下道工序使用。这样简化了加工步骤，提高了效率。Bamboo strip 132 has no green and yellow removal, and the amount of water absorbed by the glue is very small. Neither dipping nor brushing will absorb much water. It is easier to control the moisture content. It does not need to be dried, and there will be no problem of phenolic resin glue pre-curing , the produced container floor 100 has better quality and higher strength, and saves some processes, reduces energy consumption and glue consumption, and saves production costs.
