Abstract

The invention relates to a room temperature-curable high temperature-resistant anticorrosion coating. The coating comprises a component A and a component B. The component A comprises, by mass, 30-50 parts of a main film forming substance, 5-10 parts of an auxiliary film forming substance, 5-20 parts of a silicate compound, 5-15 parts of a high temperature-resistant pigment, 5-15 parts of an antirust filler, 5-15 parts of a low melting point blend, 1-5 parts of a high temperature-resistant whisker reinforcement material, 0.5-1.5 parts of a dispersant, 0.5-2 parts of an anti-settling agent, 1-2parts of a silane coupling agent and 10-20 parts of a solvent; and the component B is a titanate catalyst, and accounts for 0.5-3% of the mass of the main film forming substance. The high temperature-resistant coating has the advantages of excellent temperature resistance, good cold and heat exchange resistance, no cracking, and realization of high hardness and high adhesion after a high temperature; and the high temperature-resistant coating also has the advantages of good high temperature resistance, realization of self-curing at room temperature, high crosslink density, good corrosion resistance, simplification of the construction process, saving of the construction energy consumption, and friendliness to the environment.

Description

technical field [0001] The invention relates to a high temperature resistant anticorrosion coating, which belongs to the field of new chemical materials. Background technique [0002] Generally, metals will produce surface oxidation under high temperature conditions. Oxidation will not only cause metal loss, but also cause changes in elements in the alloy, which will seriously affect the quality of the metal and lead to a decrease in service life. Aiming at the problem of high temperature oxidation of metals, high temperature resistant coating materials are currently used more often. The high temperature resistant coating is easy to construct, low in cost and good in temperature resistance, and has been widely used in modern industry, military and aerospace fields. There are many kinds of high-temperature-resistant coatings, which are divided into organic high-temperature-resistant coatings and inorganic high-temperature-resistant coatings. They are widely used in the surfa...
