Problems solved by technology

However, the existing waterproof coatings do not have environmental protection performance, often emit pungent harmful gases, pollute the environment, are difficult to decompose, pollute the soil, and have poor bonding performance, poor corrosion resistance in marine applications, and no weather resistance. Wear-resistant, anti-pollution and self-cleaning functions bring inconvenience to people

Abstract

The invention discloses a waterproof coating with environment-friendliness, high adhesion, weather resistance, abrasion resistance, anti-fouling and self-cleaning functions. The waterproof coating isprepared from amine-terminated polyether, a liquid amine chain extender, isocyanate, oligomer diol, acrylic resin, organosilicon modified polyurethane, powder and auxiliary agents, wherein the auxiliary agents are filler, a reinforcing agent, a cross-linking agent, a catalyst, a plasticizer, a chain extender, pigment, a tackifier, a stabilizer, a flame retardant and a heat resistant agent; the power is: special cement and graded sand; the waterproof coating has excellent adhesion of metal substrate, good elongation at break and tensile strength, and can maintain excellent performance under various environments, as well as excellent water resistance, excellent solar reflectivity, excellent long-term stain resistance, excellent physical and chemical properties, high tensile and impact strength, flexibility, wear resistance, wet resistance, aging resistance, anti-corrosion protection property and the like, and can spray-coat any substrate such as steel, wood, concrete and the like.

Description

technical field [0001] The invention relates to a waterproof paint, in particular to a waterproof paint with environmental protection, high adhesion, weather resistance, wear resistance, antifouling and self-cleaning. Background technique [0002] The waterproof coating is a one-component water-emulsion waterproof coating made of pure acrylic polymer emulsion as the base material and adding other additives. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. The waterproof coating has good temperature adaptability, easy operation, easy repair and maintenance. Polyurethane waterproof coating is a single-component environmentally friendly waterproof coating for liquid construction. It is based on imported polyurethane prepolymer and has no additives such as tar and asphalt. It solidifies after e...
