Abstract

The invention discloses a quartz sand/fire clay composite alcohol group casting coating. The quartz sand/fire clay composite alcohol group casting coating is characterized by comprising following raw materials in part by weight: 40-60 of quartz sand, 30-40 of fire clay, 3-4 of rosin, 1-2 of kieselguhr, 0.2-0.4 of zinc borate, 0.1-0.3 of calcium stearate, 0.4-0.8 of magnesium chloride, 1-4 of waste foam plastic particles, 1.2-3.2 of ammonium sulfate, 1.1-2.4 of abietate, 4-7 of traditional Chinese medicine dregs, 0.3-0.6 of dichloromethane, 40-50 of ethyl alcohol, and 3-6 of an adjuvant. The coating provided by the invention has the advantages that the coating is not easy to settle, the suspension property is good, air sending volume is small, high temperature is resisted, the fire resistance is good, the coating property is good, the traditional Chinese medicine dregs after processing are added into the raw materials, the coating has an anti-mould effect, the suspension effect of the coating is improved, and thus the coating is suitable for different castings.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to an alcohol-based casting coating composed of quartz sand / refractory mud 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 c...
