Abstract

The invention discloses a novel anti-sulfuration casting coating, and relates to the field of coatings, and the novel anti-sulfuration casting coating comprises 200-400 parts of a high-activity calcium-containing magnesium-containing material, 200-500 parts of deposited calcium carbonate, 100-300 parts of calcined kaolin, 65-95 parts of furan resin sand, 55-85 parts of zircon powder, 15-45 parts of titanium dioxide, 5-9 parts of vegetable gum, 8-15 parts of a suspending agent, 4-12 parts of a surface additive, and 30-60 parts of fatty alcohol-polyoxyethylene ether. According to the anti-sulfur-seepage coating disclosed by the invention, a high-activity calcium-containing and magnesium-containing material is adopted, and calcium and magnesium elements react with sulfur at a high temperature, so that permeation of sulfur into molten metal is reduced; the superfine active powder is used, the permeation reaction of the coating to a sand mold is increased, the contact area of the coating and the sand mold is increased, and the sintering reaction effect is improved; a product reacted with a casting forms a sintering layer on the surfaces of the casting and a sand mold, so that sulfur elements in the sand mold are further prevented from permeating into molten metal, the variation of the structure of the molten metal is reduced, and the influence of sulfur in furan resin sand and a curing agent on the material of the casting is solved.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a novel anti-sulfur seepage casting coating. Background technique [0002] Foundry coating is a casting auxiliary material covered on the surface of the core during the casting process to improve its surface refractoriness, chemical stability, resistance to liquid metal erosion, anti-sand sticking and other properties; casting coating can be made into slurry, paste or In powder form, spray, brush, invade, flow and other methods are applied on the surface of the core. ZD coating can insulate the heat, balance the temperature, avoid the impact and corrosion of the molten metal, so as to protect the mold and prolong the service life of the mold. Up to 1 / 3 or more; the casting coating can effectively prevent the cracking and white iron formation of casting products caused by local cooling too fast; the casting coating adsorption time is as long as 7 days, with good air permeability, and acety...
