Permeable liquid hardener and preparation method thereof

Abstract

The invention relates to a permeable liquid hardener and a preparation method thereof. The hardener comprises raw materials in percentage by mass as follows: 10%-70% of silica sol, 1%-30% of polymerized polyhydroxyl aluminum salt, 10%-60% of water and 1%-10% of a wetting agent. Meanwhile, the preparation method is simple, raw materials are cheap, and the industrial production cost is reduced. According to the preparation method, paint can be prepared after the raw materials are mixed and dispersed, the preparation technology is simple, easy to implement and convenient to operate, industrial mass production is facilitated, the industrial production cost is reduced, and the hardener is particularly applicable to cement-based floors such as industrial plants, parking lots and the like and has broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of cement infrastructure materials, in particular to a penetrating liquid hardener and a preparation method thereof. Background technique [0002] The cement-based floor has the characteristics of high strength and low cost, and is widely used in residential, industrial, commercial and other buildings. However, cement-based building materials often have problems such as sanding and cracking on the floor due to insufficient batch stability, inadequate construction and maintenance, etc., reducing the performance of the material or losing some functions. 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 the application number CN201410185988.3 discloses a cement sealing and curing agent composed of sodium silicate, lithium silicate, magnesium fluor...

Problems solved by technology

The Chinese invention patent application with the application number CN201410185988.3 discloses a cement sealing and curing agent composed of sodium silicate, lithium silicate, magnesium fluorosilicate, sodium dihydrogen phosphate, color paste and water, which can be used in concrete Form silica gel crystals and seal the capillary pores of concrete through hydration, thereby improving the hardness and wear resistance of concrete, but it is prone to the problem of efflorescence

The Chinese invention patent application with the application number CN03116794.2 discloses a surface strengthening sealant for cement concrete, which is composed of magnesium fluorosilicate, siloxane emulsion, aluminum sulfate and water, but the surface of the surface strengthening sealant The penetration is shallow, the sealing layer formed is very shallow, and a large number of sulfate ions in it can cause microcracks, resulting in low surface hardness of concrete, so the ground wear resistance is poor
