Abstract

The invention discloses high temperature-resistant anticorrosive paint and a preparation method thereof. The high temperature-resistant anticorrosive paint is prepared from the following raw materials: epoxy-modified silicon resin, polytetrafluoroethylene resin, SiC micro powder, talcum powder, asbestos powder, glass powder, modified boric acid, a silane coupling agent, a defoaming agent, a flatting agent and a film-forming agent. The paint not only has excellent high temperature resistance performance and flame retardation performance, but also has good anticorrosive performance of salt fog resistance, water resistance, salt water resistance, ageing resistance and the like, can adapt to different construction modes, and is ideal heat-resistant anticorrosive paint.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-temperature-resistant anti-corrosion coating and a preparation method thereof. Background technique [0002] Some equipment used in high-temperature environments, such as: exhaust pipes of automobiles and motorcycles, chimneys, etc., due to long-term exposure to high-temperature and harsh environments, the life of the equipment will be reduced, so it needs to be protected. The commonly used method is spray coating. However, traditional anti-corrosion coatings are not resistant to high temperatures, have a short lifespan under high temperature conditions, and contain a large amount of metal compounds, which not only pollute the environment, but are also harmful to the human body. Contents of the invention [0003] The object of the present invention is to provide a high temperature resistant anticorrosion coating and a preparation method thereof. The coatin...
