Abstract

The invention discloses a modified pork bone type alcohol-based casting coating, which is characterized in that it is made of the following raw materials in parts by weight: high alumina cement 10-14, polyvinyl butyral 0.3-0.5, alkylsulfonic acid Sodium 0.2-0.6, zircon powder 45-60, white corundum 40-60, nano-scale clay 1-3, alkylated diphenylamine 0.1-0.3, sodium nitrate 0.2-0.4, xanthan gum 1-2, hydrogen silicone oil 1.2-3.2, pig bone 12-14, phenolic resin 3-5, hexamethylenetetramine 1-3, ethanol 40-50, auxiliary agent 3-7; the present invention adds animal bone pig bone to the raw material after modification Among them, it has a good suspension effect and high temperature resistance strength. At the same time, the coating made by compounding other raw materials has the advantages of good fire resistance, strong anti-sand sticking ability, good brushing performance, and good leveling performance. The casting coatings used by casting manufacturers rely on imports for a long time, which fills the domestic gap and has good adaptability.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a modified pork bone type alcohol-based 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. Prevent defects such as cracking, trachoma, and white iron formation caused by excessive local cooling of casting products. There are many kinds of casting coatings,...
