Problems solved by technology

However, the materials used in this patent are all nano-materials, and the cost is very high. Although it can achieve good results, it is obviously inappropriate to cooperate with the cement-based self-leveling ground with a relatively low price.

Abstract

The invention discloses an aqueous concrete sealer, which comprises the following components in percentage by weight: 45 to 65 percent of modified acrylic acid emulsion, 10 to 20 percent of modified fluorocarbon emulsion, 5 to 15 percent of film-forming assistant, 3 to 5 percent of dispersant, 3 to 8 percent of thickener, 1 to 3 percent of defoaming agent and 10 to 20 percent of wetting agent. The aqueous concrete sealer has high self-cleaning performance, can reinforce cement-based self-leveling floors, and is environment-friendly and durable. The aqueous concrete sealer disclosed by the invention can be used as finish for indoor self-leveling material, the construction process of the aqueous concrete sealer is simple, convenient and quickly, and the aqueous concrete sealer can improve the surface effect and antifouling capacity of the cement-based self-leveling material.

Description

technical field [0001] The invention relates to a water-based ground sealing agent, in particular to a high-strength water-based ground sealing agent with high performance for the surface layer of cement-based self-leveling materials. Background technique [0002] For the self-leveling ground, especially the colored self-leveling ground directly used as the surface layer, the surface is prone to dust, poor anti-fouling ability, and easy to penetrate. Therefore, it is necessary to apply another coat on the cement-based self-leveling floor. There are few reports on water-based environmental protection coatings matched with cement-based self-leveling materials in related literature. Chinese patent CN200410086569.0 discloses an environmentally friendly nano lotus leaf lacquer coating in the field of fine chemicals, which is super self-cleaning, bright in color, and the ink can be cleaned after washing. This invention completely breaks through the disadvantages of traditional c...
