Abstract

The invention discloses an epoxy polyurethane root-resistant waterproof coating. The epoxy polyurethane root-resistant waterproof coating is characterized by being prepared from the following raw materials in parts by weight: 0.3-0.6 part of a defoamer BYK-354, 0.2-0.4 part of polyester modified polydimethylsiloxane, 20-30 parts of epoxy resin, 7-9 parts of locked polyurethane, 0.1-0.3 part of blocked p-toluenesulfonic acid, 2-3 parts of micro-powder wax, 0.2-0.4 part of a dispersant EFKA015, 30-40 parts of linear-chain polyester resin, 4-6 parts of heavy calcium carbonate powder, 3-4 parts of antimonous oxide, 5-7 parts of fine stone powder, 8-10 parts of neoprene latex, 3-5 parts of silicon oxide, 2-3 parts of aluminum triphosphate, 0.5-1.0 part of phenyltrimethoxysilane, 4-6 parts of calcium carbonate whisker powder, 3-4 parts of polyisocyanate, 5-7 parts of root-resistant auxiliary, 4-6 parts of methyl isobutyl ketone, 5-7 parts of ethylene glycol butyl ether and 8-11 parts of S-1508. The epoxy polyurethane root-resistant waterproof coating has excellent adhesive force, wear resistance, weather fastness, corrosion resistance and the like; the added root-resistant auxiliary has an obvious root resisting effect and is unharmful to the plant root systems and excellent in compatibility with a resin; the epoxy polyurethane root-resistant waterproof coating is simple to prepare, high in adaptability and worthy of popularization.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an epoxy polyurethane root-blocking waterproof coating and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the gradual improvement of people's living standards, the energy crisis and environmental crisis are becoming more and more serious, and the impact on the environment is very serious. With the gradual improvement of people's awareness of environmental protection, green planting projects have gradually become the main content of urban construction, and buildings are the largest consumer of natural resources in society, so people usually cover green vegetation and rockery on the roof of the building or the roof of the basement. , pools and other landscapes, creating an ecological system that is pleasing to the eye and beautifies the environment. The green roof is generally composed of planted plants, waterp...
