Abstract

The invention relates to a fire resistant and anticorrosive coating paint with rust and the preparing method, which solves the technique problem how to provide a 300Deg. C fire resistant and anticorrosive coating paint with rust and the preparing method. The invention generates the modified polysilicate with fluosilicic acid and ethyl orthosilicate, which disperses color, filler and adjuvant in the glue solution of the composite binding material with the newest coupling dispersing technique, mixing the phosphoric acid solution; forming the active coating material system which removes the rustof the steel and iron. The paint can react with the iron rust and forms the fast and inactivating coating, which forms fire resistant, anti-rust and anticorrosive coating owing to the inorganic resinas the main film substance. The fire resistant and anticorrosive coating paint is provided with the advantages of anti-rust and fire resistant, which doesn't need to derust when painting the metal surface.

Description

technical field [0001] The invention relates to a high-temperature-resistant anti-corrosion coating with rust and a preparation method thereof. Background technique [0002] Also do not have rust high temperature resistant coating on the existing market. Contents of the invention [0003] The technical problem to be solved by the present invention is how to fill the above-mentioned gaps in the prior art, and provide a high-temperature-resistant rust-resistant anti-corrosion coating with anti-rust and anti-corrosion functions and a preparation method thereof that can withstand high temperatures above 300°C. [0004] In order to solve the above-mentioned technical problems, the high-temperature-resistant anti-corrosion coating with rust of the present invention is made from the following raw materials in weight ratio: [0005] 10% by weight polyvinyl butyral ethanol solution: 5 to 25 parts; [0006] Ethyl silicate with a silicon dioxide content of 28%: 10-50 parts; [000...
