Abstract

The invention discloses a polyurea waterproofing paint. The paint is prepared by mixing and stirring the following components in parts by weight: 40-60 parts of polyether, 40-60 parts of polyester, 1-2 parts of bactericide, 1-2 parts of defoaming agent, 8-10 parts of filler, 2-5 parts of plasticizer, 3-6 parts of curing agent, and 60-80 parts of water. The polyurea waterproofing paint is transparent after being coated on the surface of a base material to form a film, so that the color of the base material is not changed after the film is formed. Furthermore, the paint is solvent-free and pollution-free, is of a high reaction type, and is good in water seepage resistance.

Description

technical field [0001] The invention relates to a polyurea waterproof coating, which belongs to the field of new materials. Background technique [0002] Polyurea waterproof coatings are mainly used to prevent water seepage. Most of the waterproof coatings currently on the market are simply mixed with emulsion and water. After the waterproof coating is applied to the substrate, the formed film is not transparent, and the film is very thin, which is not conducive to the waterproof coating to prevent water seepage. Therefore, the development of a solvent-free, pollution-free, high-response polyurea waterproof coating is necessary. Contents of the invention [0003] Purpose of the invention: The technical problem to be solved by the present invention is to provide a solvent-free, pollution-free, high-response polyurea waterproof coating. [0004] In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: ...
