Abstract

The invention relates to the field of wood processing and protecting, and aims at providing a method for preparing a high-permeability liquid hardening agent. The method comprises the steps that water and polymeric hydroxy aluminum salt are added to a high-speed dispersion machine for low-speed stirring; fluosilicate continues to be added for high-speed dispersion; a wetting agent and an antifoaming agent continue to be added under low-speed stirring, and the high-permeability liquid hardening agent is obtained. Fluosilicate and polymeric hydroxy aluminum salt are adopted as main ingredients, and the hardness and abrasion resistance of cement can be remarkably improved. Meanwhile, the preparation method is simple, raw materials are cheap, and industrial production cost can be reduced. According to the preparation method, after the raw materials are stirred and dispersed, paint can be prepared, the preparation process is simple and easy to implement, operation is easy and convenient, large-scale industrial production is facilitated, the industrial production cost can be reduced, the high-permeability liquid hardening agent is especially suitable for cement-based floors such as industrial factory buildings and parking lots, and wide application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of cement-based building materials, in particular to a preparation method of a Portland cement high-permeability liquid hardener. 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. [0003] The Chinese invention patent application with the application number CN201410185988.3 discloses a cement sealing and curing agent composed of sodium silicate, lithium sil...
