Description
Translated fromChinese技术领域Technical Field
本发明属于功能面料技术领域，具体是一种柔性防刺且防弹的纺织物及其制造方法。The invention belongs to the technical field of functional fabrics, and in particular relates to a flexible stab-proof and bullet-proof textile and a manufacturing method thereof.
背景技术Background Art
防弹的主要机制为吸收或消耗弹头的能量，从而阻止子弹穿透，最终达到保护人体的作用；而防刺的主要机制为阻止锐器继续向前推进。二者有着本质上的不同，前者依靠的是拉伸强度，即提高材料的拉伸强度，有助于吸收或消耗弹头的能量，达到防弹的目的；后者依靠的是剪切强度，即提高材料的剪切强度有助于利器的刃部快速变形，达到防刺的目的。The main mechanism of bulletproof is to absorb or consume the energy of the bullet, thereby preventing the bullet from penetrating and ultimately protecting the human body; while the main mechanism of stab protection is to prevent the sharp weapon from continuing to move forward. The two are essentially different. The former relies on tensile strength, that is, improving the tensile strength of the material helps to absorb or consume the energy of the bullet and achieve the purpose of bulletproof; the latter relies on shear strength, that is, improving the shear strength of the material helps the blade of the sharp weapon to deform quickly and achieve the purpose of stab protection.
目前，软质材料的拉伸断裂强度与剪切强度难以同时兼顾，使得软质材料的防弹与防刺功能难以同时实现，因此有学者提出在面料表面喷涂涂层以待提高面料的拉伸断裂强度与剪切强度。方志强等研究的T26聚脲材料的拉神强度仅为25.4MPa；温喜梅等采用高压湍流分散的方式向自制的聚脲材料中加入了多壁碳纳米管，其拉伸强度为42.5MPa，二者的拉伸强度可适用于防爆领域，但远不满足对防弹性能的要求。改性环氧树脂基复合材料的拉伸强度为440MPa左右，剪切强度为250MPa左右；酚醛树脂基复合材料的拉神强度为420MPa左右，剪切强度为260MPa左右，尽管满足对防刺与防弹的需求，但由于其易受环境和气候的影响，从而改变其分子链结构，失去其原有的防弹防刺性能，缩小了其应用领域以及应用条件。At present, it is difficult to take both the tensile strength and shear strength of soft materials into account at the same time, making it difficult to achieve both the bulletproof and stab-proof functions of soft materials at the same time. Therefore, some scholars have proposed spraying a coating on the surface of the fabric to improve the tensile strength and shear strength of the fabric. The tensile strength of the T26 polyurea material studied by Fang Zhiqiang et al. is only 25.4MPa; Wen Ximei et al. added multi-walled carbon nanotubes to the homemade polyurea material by high-pressure turbulent dispersion, and its tensile strength was 42.5MPa. The tensile strength of the two can be applied to the explosion-proof field, but it is far from meeting the requirements for bulletproof performance. The tensile strength of the modified epoxy resin-based composite material is about 440MPa, and the shear strength is about 250MPa; the tensile strength of the phenolic resin-based composite material is about 420MPa, and the shear strength is about 260MPa. Although it meets the requirements for stab and bullet resistance, it is easily affected by the environment and climate, thus changing its molecular chain structure, losing its original bulletproof and stab-proof performance, and narrowing its application field and application conditions.

进一步地，所述酚类溶剂由萘酚和对硝基酚按照体积比(2～4)：1混合而成本发明与现有技术相比，具有如下技术效果：Furthermore, the phenolic solvent is prepared by mixing naphthol and p-nitrophenol in a volume ratio of (2-4):1. Compared with the prior art, the present invention has the following technical effects:
本发明的柔性防刺且防弹纺织物为双层结构，第一层为聚酰亚胺纤维布组成基底，第二层为聚脲弹性体涂层，聚脲弹性体涂层赋予织物优良的防弹、防刺和透气等性能，具体体现在：一则，聚脲弹性体为连续相，当遇到穿刺和冲击等作用时，化学键的结合力使其内部结构发生弹性变形，使外部冲击力难以对面料造成永久性损伤，从而具有良好的防刺和防弹性能；二则，聚脲弹性体具有良好的柔韧性，作为面料的涂层材料不会影响面料的柔软性；三则，聚脲弹性体富含大量的微孔，不仅使面料具有良好的透气性，而且微孔具有良好的毛细作用，使水分与涂层的接触角大于90°，从而面料具有良好的防水性；四则，聚脲弹性的微孔使其保持电中性，因而不易带电荷，有效防止在穿着过程中面料吸附灰尘。The flexible stab-proof and bullet-proof textile fabric of the present invention has a double-layer structure, wherein the first layer is a polyimide fiber cloth as a base, and the second layer is a polyurea elastomer coating. The polyurea elastomer coating gives the fabric excellent bulletproof, stab-proof and breathable properties, which are specifically embodied in the following aspects: firstly, the polyurea elastomer is a continuous phase, and when encountering puncture and impact, the binding force of the chemical bonds causes its internal structure to undergo elastic deformation, so that it is difficult for the external impact force to cause permanent damage to the fabric, thereby having good stab-proof and bullet-proof properties; secondly, the polyurea elastomer has good flexibility, and as a coating material for the fabric, it will not affect the softness of the fabric; thirdly, the polyurea elastomer is rich in a large number of micropores, which not only makes the fabric have good air permeability, but also the micropores have good capillary action, so that the contact angle between water and the coating is greater than 90 degrees, thereby the fabric has good waterproofness; fourthly, the micropores of the polyurea elastomer keep it electrically neutral, so it is not easy to carry an electric charge, and effectively prevents the fabric from absorbing dust during wearing.
利用含有纳米添加剂的氨基化合物对聚酰亚胺纤维布料基底进行氨基化处理，纳米添加剂带有的功能基团使面料基底表面拥有一定的活性，进而能够增强与聚脲弹性体之间的结合力，使得聚脲弹性体涂料不易在聚酰亚胺纤维布上脱落，能够形成抗冲击强的防刺、防弹纺织物复合材料体系。The polyimide fiber cloth substrate is treated with amino compounds containing nano-additives. The functional groups of the nano-additives make the surface of the fabric substrate have a certain activity, which can enhance the bonding force with the polyurea elastomer, making the polyurea elastomer coating not easy to fall off the polyimide fiber cloth, and forming an impact-resistant, puncture-proof and bullet-proof textile composite material system.
利用二胺和二酐制备聚酰亚胺纤维，由于二胺中苯环的存在，使聚酰亚胺纤维的性能更加稳定，寿命长，且由于N-(1-萘基)乙二胺二盐酸盐和咖啡酰丁二胺均具有较高的熔沸点，使聚酰亚胺纤维面料基底更加耐高温。Polyimide fiber is prepared by using diamine and dianhydride. Due to the presence of benzene ring in diamine, the performance of polyimide fiber is more stable and the service life is longer. In addition, since N-(1-naphthyl)ethylenediamine dihydrochloride and caffeoylbutanediamine both have high melting and boiling points, the polyimide fiber fabric base is more resistant to high temperatures.
加入发泡剂使聚脲弹性体在凝固时部分区域去漆化，从而形成更加丰富的微孔，进一步增强面料的透气性、防水性和防灰作用。The addition of a foaming agent allows the polyurea elastomer to partially de-paint during solidification, thereby forming more abundant micropores, further enhancing the fabric's breathability, waterproofness and dust resistance.

考虑到面料在长期的服役过程中，应用领域的不确定性，尤其是在有些极端环境中的紫外线辐射太强，而有些环境中可能菌类较多，而紫外线与菌类是影响面料性能的两个重要的因素因素，原因在于：1)、当聚脲层受到环境中的紫外线影响时，其分子连段中的某些化学键因吸收能量会发生断裂，使得由大分子链构成的网络结构变成小分子链，从而降低了其拉伸强度与剪切强度，进而丧失了原有的防弹防刺性能。2)、由于在复杂的细菌环境中，有些细菌的分泌物会与聚脲分子链发生化学反应，导致化学键断裂的概率大大提高，直接导致拉伸强度与剪切强度下降的概率提高，从而降低材料的防弹防刺性能，不仅仅是聚脲层，纤维层同样会受到相同的影响。本发明中，面料表面喷涂的聚脲弹性体材料在微观上为交织的网络结构以及纳米添加剂使面料拥有紫外线屏蔽功能(不低于93％)以及抑菌抗菌性能(不低于99.4％)。表1是实施例1～实施例7制备的纺织物的各项性能参数，其中：凹陷指的是面料受到子弹撞击后，产生的凹痕深度；穿透层数指的是将50层厚0.5mm的纺织物叠加在一起进行射击时，子弹共穿透的层数。Considering the uncertainty of the application field of fabrics during long-term service, especially in some extreme environments where ultraviolet radiation is too strong, and in some environments where there may be more fungi, ultraviolet rays and fungi are two important factors that affect the performance of fabrics. The reasons are: 1) When the polyurea layer is affected by ultraviolet rays in the environment, some chemical bonds in its molecular segments will break due to absorption of energy, so that the network structure composed of macromolecular chains becomes small molecular chains, thereby reducing its tensile strength and shear strength, and then losing the original bulletproof and stab-proof performance. 2) Because in a complex bacterial environment, some bacterial secretions will react chemically with the polyurea molecular chain, resulting in a greatly increased probability of chemical bond breakage, which directly leads to an increased probability of tensile strength and shear strength reduction, thereby reducing the bulletproof and stab-proof performance of the material, not only the polyurea layer, but also the fiber layer will be affected in the same way. In the present invention, the polyurea elastomer material sprayed on the surface of the fabric is an interwoven network structure at the microscopic level, and the nano additives enable the fabric to have ultraviolet shielding function (not less than 93%) and antibacterial and antibacterial performance (not less than 99.4%). Table 1 shows the performance parameters of the textiles prepared in Examples 1 to 7, wherein: depression refers to the depth of the dent produced when the fabric is hit by a bullet; the number of penetration layers refers to the number of layers penetrated by the bullet when 50 layers of 0.5 mm thick textiles are stacked together and shot.
