Abstract

The invention discloses high-temperature-resistant environment-friendly metal casting coating and a preparation method thereof. The coating comprises, by weight, 3-5 parts of attapulgite clay, 12-15 parts of quartz powder, 5-12 parts of talcum powder, 4-10 parts of superfine glass powder, 1.5-4 parts of sodium silicate, 3-5 parts of bauxite, 3-8 parts of diatomaceous earth, 2-4 parts of bentonite, 6-10 parts of polyethylene glycol, 3-9 parts of organic siloxane, 5-9 parts of silicon resin, 6-12 parts of linseed oil water-soluble alkyd resin, 4-6 parts of triphenyltin hydroxide, 2-6 parts of lignosulfonic acid, 1-3 parts of oxidizing agents, 1-2 parts of wetting agents, 2-5 parts of defoaming agents, 4-9 parts of preservatives, 2-6 parts of bonding agents, 5-8 parts of curing agents and 75-90 parts of deionized water. Compared with the prior art, the casting coating prepared through the method has excellent high temperature resistance, crack resistance and scouring resistance, and is good in adhesiveness and air permeability; meanwhile, the produced coating is uniform, environmentally friendly, free of pollution, good in stability and adsorbability, and capable of meeting the requirements for mass production of large castings, and improves the surface quality of the castings.

Description

technical field [0001] The invention relates to the technical field of casting coatings, in particular to a high-temperature resistant and environment-friendly metal casting coating and a preparation method thereof. Background technique [0002] Foundry coatings refer to casting auxiliary materials that are used to coat the surface of the cavity or sand core to change their surface refractoriness, chemical stability, metal erosion resistance, sand sticking resistance, etc. It is composed of various properties. It is a dispersion system composed of high-quality materials, and its composition mainly includes refractory materials, suspending agents, carriers, binders and special additives. When acting on castings, it is required that the coating has good process performance, work performance, quality stability and application reproducibility. It has been widely used in the production of steel, iron, and non-ferrous castings to prevent defects such as cracking, trachoma, and wh...
