本发明属于矿物材料深加工和建筑材料技术应用领域，更具体地讲，涉及一种水泥基灌浆材料用黏度调节剂及其制备方法。The invention belongs to the technical application field of mineral material deep processing and building materials, and more particularly relates to a viscosity regulator for cement-based grouting materials and a preparation method thereof.
背景技术Background technique
随着我国基础设施建设的发展，水泥基灌浆材料作为一种具有大流动度、早强高强和无收缩的灌浆修补材料，被广泛用于大型设备和精密设备的安装，地脚螺栓的锚固，混凝土结构的加固与改造，以及预应力混凝土结构的孔道灌浆等方面。一些大型工程由于引进了许多国外先进设备，设备厂商和设计单位往往对流动度提出很高要求。目前我国已经颁布了两份标准，分别是GB/T50448-2015《水泥基灌浆材料应用技术规范》和JC/T986-2018《水泥基灌浆材料》。一些灌浆料生产厂家因为市场竞争一味追求大流动性，忽视了工作性评价还包括新拌砂浆的稳定性和黏聚性、离析泌水等丰富内涵。当新拌砂浆表现出流动性不足时，现场施工人员往往通过掺加水或者减水剂来提高流动性。在这种情况下，水泥基灌浆材料很容易发生离析泌水和易性变差。With the development of infrastructure construction in China, cement-based grouting material, as a grouting repair material with high fluidity, early strength, high strength and no shrinkage, is widely used in the installation of large-scale equipment and precision equipment, anchoring of anchor bolts, Reinforcement and reconstruction of concrete structures, as well as channel grouting of prestressed concrete structures. Due to the introduction of many foreign advanced equipment in some large-scale projects, equipment manufacturers and design units often put forward high requirements for mobility. At present, my country has promulgated two standards, namely GB/T50448-2015 "Technical Specifications for Application of Cement-based Grouting Materials" and JC/T986-2018 "Cement-based Grouting Materials". Some grouting material manufacturers blindly pursue high fluidity due to market competition, ignoring the rich connotations of workability evaluation, including the stability and cohesion of freshly mixed mortar, and segregation and bleeding. When the fresh mortar shows insufficient fluidity, the on-site construction workers often improve the fluidity by adding water or water reducing agent. In this case, the cement-based grouting material is prone to segregation, bleeding and poor workability.
针对上述现象，行业内也开发了温伦胶、聚丙烯酰胺、纤维素醚等一系列的材料来改善灌浆料的黏度，但存在如下问题：温伦胶类由于其黏度较大，在掺量很低时就有增稠效果。如果控制不好掺量，往往会造成新拌砂浆流动度的下降。尤其在厂家生产设备和计量设备不是很精确的时候，这一现象越发明显。而纤维素醚类产品应用在水泥基灌浆材料上的一般都是低粘度的，这类纤维素醚类产品生产工艺复杂，国内能生产的企业很少，多依赖国外进口，往往价格昂贵。除此之外，纤维素醚类产品还具有明显的引气和缓凝效果，这也使得它的应用受限。In response to the above phenomenon, a series of materials such as Wenlun glue, polyacrylamide, and cellulose ether have also been developed in the industry to improve the viscosity of the grouting material. There is a thickening effect at very low levels. If the dosage is not well controlled, the fluidity of the fresh mortar will often decrease. Especially when the manufacturer's production equipment and measuring equipment are not very accurate, this phenomenon becomes more and more obvious. However, the cellulose ether products used in cement-based grouting materials are generally of low viscosity. The production process of such cellulose ether products is complex, and there are few domestic enterprises that can produce them. They rely on foreign imports and are often expensive. In addition, cellulose ether products also have obvious air-entraining and retarding effects, which also limits their application.

Further, the viscosity modifier can be made from the following raw materials in parts by weight: 5 to 18 parts of layered silicate minerals, 0.2 to 2.7 parts of water-soluble polymers, and 0.5 to 2.7 parts of defoamer 1.5 parts, 80 to 90 parts of water, and 0.1 to 0.2 parts of an aqueous conditioner. Further, the viscosity modifier can be made from the following raw materials in parts by weight: 7 to 18 parts of layered silicate minerals, 0.4 to 2.7 parts of water-soluble polymers, and 0.8 parts of defoamer ~1.5 parts, 85 to 90 parts of water, 0.1 to 0.2 parts of an aqueous conditioner. For example, the viscosity modifier is composed of the following components in parts by weight: 15 parts of layered silicate minerals, 2.5 parts of water-soluble polymer, 0.9 parts of defoamer, 88 parts of water, and 0.15 parts of aqueous solution regulator share. The viscosity modifier contains calcium dioxide, aluminum oxide, calcium oxide, magnesium oxide and other material components.
在本实施例中，本发明是以层状硅酸盐矿物为主体原料来制备水泥基灌浆材料用黏度调节剂。本发明所使用的层状硅酸盐矿物主要构造单元可以是二维排列的硅氧四面体和铝(或镁)氧八面体。所述两个构造单元可以按照硅氧四面体:铝(或镁)氧八面体为1:1或2:1组成不同的结构层。结构层间通常可以以范德华力连接。这种分子间作用力较弱，水分子易于进入晶胞层间发生膨胀或剥离。因此，上述特殊的层状结构使本发明所使用的层状硅酸盐具有较好的吸水膨胀性、分散悬浮性和触变性，其吸水后形成的溶胶在搅拌时黏度下降，有利于水泥基灌浆材料的流动性；而静置后形成的凝胶使得黏度上升，有利于阻止水泥颗粒和骨料的下沉以及自由水的析出；当再施加外力搅拌时，凝胶结构又可以被迅速打破，恢复流动性。In this embodiment, the present invention uses layered silicate minerals as the main raw material to prepare the viscosity modifier for cement-based grouting materials. The main structural units of the layered silicate minerals used in the present invention can be two-dimensionally arranged silicon-oxygen tetrahedron and aluminum (or magnesium)-oxygen octahedron. The two structural units can form different structural layers according to the ratio of silicon-oxygen tetrahedron: aluminum (or magnesium)-oxygen octahedron to 1:1 or 2:1. The structural layers can usually be connected by van der Waals forces. This intermolecular force is weak, and water molecules are easy to enter the unit cell layer to expand or peel off. Therefore, the above-mentioned special layered structure enables the layered silicate used in the present invention to have better water-swelling, dispersing and suspending properties and thixotropy, and the sol formed after water-absorbing is reduced in viscosity during stirring, which is beneficial to cement-based The fluidity of the grouting material; the gel formed after standing makes the viscosity rise, which is beneficial to prevent the sinking of cement particles and aggregates and the precipitation of free water; when external force is added to stir, the gel structure can be quickly broken again , to restore liquidity.

Of course, the water-soluble high molecular polymer of the present invention is not limited to this. For example, the water-soluble high molecular polymer used in the present invention may increase the viscosity of the viscosity modifier of the present invention. The long-chain molecules of the water-soluble macromolecular polymer of the present invention adsorb and fix free water molecules, so that the apparent volume of the solution increases due to water absorption and swelling, and finally leads to an increase in the viscosity of the solution
在本实施例中，所述消泡剂可以为粉末有机硅消泡剂。当然，本发明的消泡剂不限于此，可以消除体系中已经形成的气泡，并且抑制新的气泡的产生即可。In this embodiment, the defoamer may be a powdered silicone defoamer.

本发明的另一方面提供了一种水泥基灌浆材料用黏度调节剂制备方法，在本发明的水泥基灌浆材料用黏度调节剂制备方法的一个示例性实施例中，如图1所示，所述制备方法可以包括：Another aspect of the present invention provides a method for preparing a viscosity modifier for cement-based grouting materials. In an exemplary embodiment of the method for preparing a viscosity modifier for cement-based grouting materials of the present invention, as shown in FIG. The preparation method can include:
步骤S01，按重量份计，将5份～20份层状硅酸盐矿物、0.2份～3.0份水溶性高分子聚合物以及0.5份～2.0份消泡剂均匀混合，得到混合物。Step S01, in parts by weight, uniformly mix 5 parts to 20 parts of layered silicate minerals, 0.2 parts to 3.0 parts of water-soluble polymer and 0.5 parts to 2.0 parts of defoamer to obtain a mixture.

在本实施例中，例如，层状硅酸盐矿物可以为4份～18份，水溶性高分子聚合物0.3份～2.9份，消泡剂0.7份～1.8份。In this embodiment, for example, the layered silicate minerals may be 4 parts to 18 parts, the water-soluble high molecular polymer 0.3 parts to 2.9 parts, and the defoaming agent 0.7 parts to 1.8 parts.

在本实施例中，所述搅拌可以在2500转/分～3500转/分的转速下进行搅拌。进一步的，可以在3000转/分的转速下搅拌。上述搅拌速度产生的剪切作用力可以保证层状硅酸盐矿物打开层间空间，让矿物颗粒稳定存在于溶液中，又不至于因剪切作用力过大而使得颗粒发生聚集而沉降。搅拌时间可以达到搅拌均匀即可。例如，搅拌时间可以为20分钟～40分钟。在温室下的密封静置时间可以是18小时～30小时，例如，静置时间可以为24小时。In this embodiment, the stirring may be performed at a rotational speed of 2500 rpm to 3500 rpm.

从上表1和表2可以看出，采用本发明的黏度调节剂，可以配置出具有良好流动性和流动保持能力，无泌水离析现象的水泥基灌浆材料。在水泥基灌浆材料的配置过程中，由于温伦胶不能与聚羧酸减水剂相容，所以不能使用，并且纤维素醚因对水泥缓凝过大影响灌浆材料硬化后强度也不能使用。It can be seen from the above Tables 1 and 2 that, by using the viscosity modifier of the present invention, a cement-based grouting material with good fluidity and flow retention ability and no bleeding and segregation can be configured. In the configuration process of cement-based grouting material, because Wenlun glue is not compatible with polycarboxylate water reducer, it cannot be used, and cellulose ether cannot be used because it has too much retardation on cement and affects the strength of grouting material after hardening.
