Abstract

The invention discloses a nano titanium oxide alcohol-based casting coating, which is characterized by being prepared from the following raw materials by weight: 75-85 parts of zircon powder, 0.3-0.6 part of aluminum chloride, 1-2 parts of organic bentonite, 0.4-0.7 part of ethylene bis stearamide, 0.2-0.5 part of antioxidant 1076, 1-3 parts of nano titanium oxide, 7-10 parts of expanded perlite, 4-6 parts of starch, 0.8-1.5 parts of potassium iodide, 2-5 parts of phenolic resin, 3-7 parts of hexamethylenetetramine, 40-50 parts of ethanol and 3-6 parts of an assistant; the nano titanium oxide alcohol-based casting coating is prepared by modified addition of the starch into the raw materials by use of a special process, so that the adhesion performance of the coating is increased, the coating prepared by optimized preparation method has the advantages of high temperature resistance, good abrasion resistance, and good air permeability.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a nano-titanium oxide 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, whi...
