Abstract

The invention relates to a liquid hardening agent with high wear resistance and a preparation method thereof. In terms of 100% of the mass of the hardening agent, the liquid hardening agent is prepared from the following raw materials: 50-90% of silicate ester, 1-30% of aluminum salts, 1-30% of alcohol and 1-5% of a catalyst, wherein the silicate ester is selected from one or a combination of more of methyl silicate, ethyl silicate, tri(methyl silicate), and preformed polymer of methyl silicate and ethyl silicate; the aluminum salt is selected from one or a combination of more of aluminum chloride, aluminum nitrate, aluminum chlorohydrate, polymer aluminum nitrate, aluminum formate, aluminum acetate, aluminum methoxide, aluminum ethylate and aluminum isopropoxide. According to the liquid hardening agent, silicate ester and the aluminum salt are adopted as the main ingredients, so that the content of the active ingredients is higher than that of a common water-based product, and the permeability is extremely high, and therefore, the hardness and wear resistance of cement can be remarkably improved. Meanwhile, the preparation method is simple and is beneficial to reduction in the industrial production cost.

Description

technical field [0001] The invention belongs to the technical field of cement infrastructure materials, and in particular relates to a high wear-resistant liquid hardener and a preparation method thereof. Background technique [0002] As the most important modern building material, cement-based building materials have the characteristics of high strength, low cost, and various types. However, cement-based building materials often have interconnected capillary pores in the material due to insufficient batch stability, inadequate construction and maintenance, and even disadvantages such as sanding and cracking, resulting in reduced performance of the material or loss of certain properties. Function. Through post-improvement of cement-based materials, the performance of cement-based materials can be improved, which has significant environmental and economic benefits. The Chinese invention patent application with publication number CN201110354668.2 discloses a lithium-based co...
