Abstract

The invention discloses a city building waste alcohol-based casting coating. The city building waste alcohol-based casting coating is characterized by being prepared from the following raw materials in parts by weight: 65-85 parts of quartz tailings, 14-20 parts of high-alumina cement, 1-2 parts of magnesium oxide, 2-3 parts of ferric oxide, 1-3 parts of furnace clinker, 5-8 parts of petroleum coke, 0.3-0.6 parts of an MCA fire retardant, 0.7-1.2 parts of a styrene-acrylic emulsion, 8-14 parts of city building wastes, 2-4 parts of phenolic resin, 2-5 parts of hexamethylenetetramine, 45-60 parts of ethanol and 3-6 parts of an aid. The preparation method has the advantages that the materials are reasonably selected, and the process is simple; the city building wastes are added into the raw materials after being modified, so that various technical indexes of the coating are enhanced, meanwhile, the processing problem of the wasted building wastes is relieved, the environment is protected, and the prepared coating has good sintering character, high temperature resistance and heat preservation character.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to an alcohol-based casting coating for urban construction waste 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 coa...
