Full-mold casting paint and preparation method thereof

Abstract

The invention discloses full-mold casting paint, and belongs to the technical field of casting paint. The full-mold casting paint comprises, by weight, 15-17 parts of crystalline flake graphite, 10-15 parts of cyanite powder, 20-24 parts of spodumene powder, 8-10 parts of ceramic fibers, 6-9 parts of zirconium silicate powder, 14-15 parts of aluminum powder, 4-7 parts of forsterite powder, 0.5-0.8 part of iron oxide powder, 17-20 parts of phenolic resin, 1-2 parts of methyl alcohol, 0.01-0.05 part of a surface active agent, 4-6 parts of a defoaming agent, 1-2 parts of an anticorrosive agent, 0.5-1 part of a carbon adsorbing agent, and 24-26 parts of water. The invention further discloses a preparation method of the full-mold casting paint. The full-mold casting paint is environmentally friendly, resistant to corrosion, excellent in high-temperature resistance and fire resistance and high in mechanical strength.

Description

technical field

[0001] The invention relates to the technical field of casting coatings, in particular to a solid casting coating and a preparation method thereof. Background technique

[0002] The solid casting coating is a dispersion system composed of a variety of materials with different properties. Its composition mainly includes refractory materials, polyvinyl alcohol, carriers, nano-attapulgite and special additives. The coating needs to have good process performance and work performance. , quality stability and application reproducibility. The solid casting paint is coated on the outer surface of the foam plastic model, and the molding can only be poured after the paint is dry. Foamed plastics are airtight, have a low heat distortion temperature (about 70°C), and have poor affinity for water; foamed plastics are heated and melted, and after gasification, there are many liquid residues and a large amount of gas generation. If these gases and liquid residues cannot be...
