Abstract

The invention discloses a high-performance water-proof mildew-proof coating. The high-performance water-proof mildew-proof coating is prepared from talcum powder, ammonium dichromate, silicate cement, alkylphenol polyoxyethylene ether phosphate, KH-560, polyquaternium-modified sulphonated polyether amine-hyperbranched polypyrrolone copolymer, 2-naphthylamine-5-sulphonic acid, deionized water and dimethyl sulfoxide. The invention also discloses a preparation method for the high-performance water-proof mildew-proof coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a high-performance waterproof and mildew-proof coating and a preparation method thereof. Background technique [0002] With the continuous development of the construction industry, the use of architectural waterproof coatings continues to increase. In the prior art, architectural waterproof coatings generally use acrylic emulsion as a film-forming substance and water as a dispersion medium, which can reduce the emission of volatile organic compounds, reduce energy consumption, and reduce the impact of coatings on the human body during production, construction, and application. harm and pollution to the environment. However, due to poor weather resistance, flame retardancy and water resistance of acrylic polymers, the service life of architectural waterproof coatings is greatly affected. In addition, such coatings do not have anti-mildew and anti-b...
