Abstract

The invention discloses a high-temperature-resistant, anti-corrosion and thermal-insulation coating which comprises components in parts by weight as follows: 45-60 parts of film-forming resin, 20-30 parts of a pigment and filler, 15-30 parts of an aid and 25-30 parts of a solvent. The invention further designs a preparation technology of the high-temperature-resistant, anti-corrosion and thermal-insulation coating. The technology comprises steps as follows: firstly, mixing the film-forming resin with the pigment and the filler, sequentially adding an antifoaming agent, a leveling agent, a coupling agent, a crosslinking agent and a curing agent, and evenly stirring the mixture at the normal temperature to obtain the high-temperature-resistant, anti-corrosion and thermal-insulation coating. The coating has the advantages of environment-friendliness, low cost, high hardness, long service life, good heat resistance, good flexibility, good high-temperature resistance and the like.

Description

technical field [0001] The invention belongs to the field of paint preparation, and in particular relates to a high-temperature-resistant, anti-corrosion, heat-insulating paint and a preparation process thereof. Background technique [0002] With the continuous development of my country's modern industry, especially in metallurgy, petrochemical, energy, new materials and military industries, more and more high-temperature equipment and supporting facilities are used. However, metal materials are prone to contact with oxygen in the air in high-temperature environments. Oxidation reaction occurs and rust occurs, so that the metal material gradually loses its strength and leads to structural loss, which becomes a hidden danger of various accidents. Therefore, the surface of high-temperature equipment generally needs to be protected by coating with high-temperature resistant anti-corrosion coatings to prevent oxidation and corrosion of metal materials and prolong the service life...
