Waterproof coating with chemical cross-linking and physical mortise and tenon with cement

Abstract

The invention provides a waterproof coating capable of chemical crosslinking and physical mortise and tenon with cement. The waterproof coating is characterized by comprising the following raw materials by weight: 20-50 parts of a synthetic rubber latex, 20-50 parts of emulsified asphalt, 0.5-2 parts of a functional additive and 0.5-2 parts of a dispersant, 20-40 parts of a filler and 10-25 parts of water. The principle is that through coupling effect of the functional additive, part of the molecules in the synthetic rubber and most molecules in the asphalt couple into large molecules with reaction activity; when the large molecules contact with a base plane, the non-reactive molecule segments of the rubber and asphalt and the base plane form physical adsorption, and the molecular segments with reaction activity conduct react with the base plane to form chemical bond effect, so as to generate strong adhesive force; and after bonding, the coating is hardly influenced by environmental factors. Therefore, the waterproof coating provided by the invention has excellent waterproof performance.

Description

technical field [0001] The invention relates to a waterproof coating, especially a coating capable of chemically reacting with cement and concrete to bond. Background technique [0002] The waterproof paint is painted on the surface of the building. After the volatilization of the solvent or water or the chemical reaction of the components in the two paints, a thin film is formed on the surface of the building to protect the surface of the building from water, so as to prevent water and moisture. role. The waterproof performance of the waterproof coating is related to the adhesion, extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance of the film formed. The bonding strength between the film and the base surface is an important indicator for testing the waterproof performance of waterproof coatings. The bonding strength is strong and the waterproof effect is good. At present, the traditional waterproof coatings on the market mainly rely...

Problems solved by technology

Coatings applied to smooth interfaces, such as plastic pipes, ceramic tile glazes, etc., due to the weak adhesion between the waterproof layer and the smooth surface, it is easier to fall off, causing water channeling and water leakage
