Abstract

The invention discloses a high-cost performance alcohol-based foundry coating. The high-cost performance alcohol-based foundry coating is characterized by being prepared from the following raw materials in parts by weight: 75-90 parts of emery, 2.3-4.5 parts of silica gel powder, 4.1-6.2 parts of asbestos powder, 3-5 parts of attapulgite, 1.2-3.1 parts of E12 epoxy resin, 2.4-3.6 parts of phenolic resin, 1-2 parts of polybenzimidazole fiber, 0.4-0.7 parts of coco fatty acid diethanol amide, 0.7-0.9 parts of butadiene styrene rubber, 12-15 parts of shrimp shell, 11-13 parts of flaxseed meal, 1-3 parts of rosin, 45-60 parts of ethanol and 2-4 parts of auxiliaries. According to the high-cost performance alcohol-based foundry coating, the shrimp shell and the flaxseed meal are added to the raw materials after being specially treated, so that the production cost of the coating is reduced and various performance indexes of the coating are also increased; the obtained coating has the advantages of high cost performance, high-temperature resistance, good suspension property and the like, and is suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to an alcohol-based casting coating with high cost performance 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. Prevent defects such as cracking, trachoma, and white iron formation caused by excessive local cooling of casting products. There are many kinds of casting coati...
