Abstract

The invention provides a polymer cement elastic protective coating composition that comprises a liquid component A, a liquid component B and a powder component C, and the mass ratio of the liquid component A to the liquid component B to the powder component C is 1:1:2. According to the invention, the polyurethane emulsion and the carboxyl crosslinking aid are introduced; by modifying the traditional mixing mode, polyurethane emulsion which is originally difficult to add into a cement system can be stably dispersed into cement paste, and meanwhile, a powder system is regulated and controlled, the mechanical property of a coating is improved through joint work of a liquid material, powder and a homogenization mode, and thereby the high-strength and high-ductility polymer cement elastic coating composition is obtained.

Description

technical field [0001] The invention relates to the field of polymer cement protective coatings, in particular to a high-strength and high-ductility polymer cement elastic protective coating composition and a homogenization method thereof. Background technique [0002] Polymer cement waterproof coatings are widely used in the field of building waterproofing, and are non-polluting, environmentally friendly water-based coatings. The polymer cement waterproof coating forms an interpenetrating network structure (IPN) through the combination of cement hydration reaction products and emulsion dehydration film formation, forming an organic-inorganic organic-inorganic coating that is elastic and has good adhesion and adaptability to the cement concrete base. The coating has good elongation and adhesion, and there is unhydrated cement in the polymer cement waterproof coating, which is self-closing, which is significantly different from other types of polymer waterproof coatings, and ...
