Abstract

The invention discloses a polyurethane fireproof building exterior wall coating and a production method thereof. The polyurethane fireproof building exterior wall coating comprises the main components of water-setting type polyurethane, waterborne acrylic resin and a fire retardant namely polytetrafluoroethylene, overcomes some defects of single polyurethane or single polyacrylic resin, such as poor stability, white thickening property and gloss retention of a film, high solid content, narrow application range and the like, and achieves a complementary effect in nature. The composite coating has the advantages of the two, has the characteristics of good fireproof property, wear resistance, corrosion resistance, brightness, softness, elasticity, water resistance and mechanical properties, good weathering resistance, good fire proof property and the like, and also has high glossiness, high elasticity and excellent weathering resistance. Compared with conventional other polyurethane coatings, the polyurethane fireproof building exterior wall coating has the advantages of being convenient in construction, being fireproof, nontoxic, pollution-free, environment-friendly, and the like.

Description

technical field [0001] The invention relates to a building coating, in particular to a polyurethane building exterior wall coating. Background technique [0002] Due to the increasingly developed world industry and the destruction of nature by humans, energy conservation and consumption reduction has attracted the attention and attention of countries all over the world. my country's building energy consumption accounts for more than 30% of human energy consumption. Improve the thermal insulation performance of buildings and improve The use function of buildings, energy saving and consumption reduction are another important considerations in the design of building material selection. In the field of architectural coatings, the development goals at home and abroad are also developing in the direction of high efficiency, energy and resource saving, harmlessness and pollution-free. The architectural heat-reflecting and heat-insulating coatings developed in recent years are not o...
