Abstract

A high-molecular water-proof paint for roof is prepared from acrylic emulsion, organosilicon emulsion, water as solvent and other assistants. Its advantages are no poison, ordour and environmental pollution, high resistance to water, ultraviolet radiation and ageing, rich colors and high adhesion.

Description

technical field [0001] The invention belongs to the coating class in chemical industry. Specifically, it is a waterproof coating used on the roof of a building. Background technique [0002] At present, the types of roof waterproof coatings in my country are relatively single. Among them, the main products are, one is polyurethane, which has better quality but higher price. For now, the vast majority of polyurethanes still use xylene as a solvent, which is toxic, affects the health of operators, and seriously pollutes the environment. Although solvent-free polyurethane has been researched in my country, it is rarely used in the market; the other is waste rubber modified asphalt. It costs less and is of lower quality. It is easy to catch fire when producing this product, and the safety hazard is very large; there is also acrylic emulsion. It uses water as a solvent, is non-toxic, has good quality, moderate price, and has great development prospects. However, the acrylic...
