Abstract

The invention discloses antibacterial anticorrosive coating for a building external wall. The coating is prepared from the following raw materials in parts by weight: 55-65 parts of silicone acrylic emulsion, 9-12 parts of perfluorosiloxane resin, 3-4 parts of an antibacterial agent, 2-3 parts of hydroxyethyl cellulose, 0.5-0.7 part of chlorinated paraffin, 0.3-0.4 part of ammonium trimolybdate and 0.8-1 part of an auxiliary agent. The invention also discloses a preparation method of the antibacterial anticorrosive coating. According to the invention, the silicone acrylic emulsion and the perfluorosiloxane resin are used as film-forming substances of the coating, so that the coating has good waterproof performance; the self-made antibacterial agent is added into the coating, has multiple and efficient antibacterial properties, has good compatibility with a coating matrix and can be uniformly dispersed in the coating; nano particles can block pores of a coating to a certain extent, thecompactness and hydrophobicity of the coating layer are improved, and the corrosion resistance and antibacterial property of the coating are improved. The waterproof coating with antibacterial and anticorrosive properties is prepared and is suitable for coating of building exterior walls.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an antibacterial and antiseptic coating for building exterior walls and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the real estate industry, the demand for exterior wall coatings is increasing, and people's requirements for architectural appearance are also constantly improving. The environmental conditions in different regions are quite different. For some cities with developed heavy industry and mining industry, due to the large amount of dust and other suspended substances in the atmosphere, the coating will lose its original decorative effect. Coatings applied to exterior wall concrete or exterior wall panels are exposed to the atmospheric environment and undergo natural changes in climate such as wind, sun, and rain, which will cause the coating to chalk, discolor, peel off, stain, etc...
