Abstract

The invention discloses a preparation method of a high-temperature-resistant and corrosion-resistant coating, and relates to the field of coating preparation. The technical problem that an existing coating is poor in high temperature resistance and corrosion resistance is solved. The method comprises the following steps: weighing raw materials; uniformly mixing nano-silver, nano-zinc, nano-copper, benzyl bromoacetate, 2, 2, 4-trimethyl-1, 3-pentanediol monoisobutyrate and water to obtain a mixed solution; putting titanium dioxide, alumina powder, quartz powder, fly ash, wollastonite powder and kaolin into a ball mill for ball milling and uniform stirring, and then adding titanium carbide, titanium diboride, titanium nitride and graphene powder to obtain a mixed material; adding melamine, aluminum silicate, silicon oxide, epoxy resin, a dispersing agent, barium sulfate and a mixed solvent; and adding expanded perlite, hollow glass micropowder and wet-ground sericite. The void ratio of the high-temperature-resistant coating is increased, the heat conductivity coefficient of the high-temperature-resistant coating is reduced, and the coating has the sterilization and mildew removal effects, can be attached to the outer wall of a building for a long time and is high in reliability. The method is used for preparing the high-temperature-resistant and corrosion-resistant coating.

Description

technical field [0001] The invention relates to the field of paint preparation. Background technique [0002] Coatings are one of the indispensable materials for the development of the national economy. Due to the many special functions of coatings, there are many kinds of coatings. Among them, architectural coatings have the functions of decoration, protection and habitability improvement. With the development of the economy, people's demand for architectural coatings continues to grow, and at the same time more requirements are put forward for the functionality of coatings. Due to the large amount of exterior wall coatings, there is a certain market for exterior wall coatings in terms of high temperature resistance and anti-corrosion. need. And at present commonly used exterior wall coating usually just takes place mildew after painting for a period of time, even comes off, and has a strong impact on the aesthetics of metope; In addition, the high temperature resistance ...
