Problems solved by technology

[0004] In the prior art, concrete floor hardeners at home and abroad mainly include three types of products: the first type of early products are sodium-based salt products, this kind of hardener can improve concrete strength and wear resistance to a limited extent, but its disadvantage is poor durability If the control is not good, pan-alkali will turn white easily, and the construction requirements are relatively high; the second type of product is potassium-based products, the performance of this hardener is improved compared with sodium-based products, but the improvement is not ob

Abstract

The invention belongs to the field of construction materials, in particular to a bi-component aqueous ground hardening agent and a preparation method thereof. The bi-component aqueous ground hardening agent comprises the following components in percentage by weight: 12-35 percent of first component and 65-88 percent of second component, wherein the first component is a lithium silicate solution, and the second component contains magnesium fluosilicate, silane emulsion, crylic acid resin emulsion, petrolin and water. The bi-component aqueous ground hardening agent has favorable effects of abrasion resistance, reinforcement, compactness, water prevention and seal and can improve the surface smoothness; and after being applied to the concrete ground, the bi-component aqueous ground hardening agent can improve the surface smoothness of concrete and reduce the dust.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a two-component water-based ground hardener and a preparation method thereof. Background technique [0002] Concrete is the most widely used man-made building material and is widely used in various structural projects. However, ordinary cement concrete structures, such as roads and floors, generally have low surface smoothness, easy dusting, poor wear resistance, low strength, easy oil penetration, difficult to clean, easy to powder, and relatively high management and maintenance costs. Defects such as high height and poor aesthetics and comfort. In order to overcome these shortcomings, the solution people usually adopt is to lay floor tiles, wooden floors on the surface of the floor or directly coat various organic polymer floor coatings such as resin paint and floor paint on the surface of the concrete floor. The solutions all have their own certain shortcomings:...
