Abstract

The invention discloses an alcohol-based foundry coating of blast furnace slag. The alcohol-based foundry coating is characterized by being prepared from the following raw materials in parts by weight: 30-40 parts of flint clay, 40-50 parts of chromite, 2-4 parts of clay sand, 15-20 parts of blast furnace slag, 4-8 parts of sodium silicate-bonded sand, 1-2 parts of TRFR high-flame retardant and high-viscosity resin, 0.2-0.5 part of silane coupling agent, 0.3-0.6 part of polyvinyl alcohol fiber, 0.4-0.7 part of sodium carbonate, 9-12 parts of chestnut shell, 1-3 parts of vinyl silicone oil, 2-6 parts of phenolic resin, 3-4 parts of hexamine, 40-55 parts of ethanol and 3-6 parts of assistant. The alcohol-based foundry coating is low in production cost, and the blast furnace slag is added to the raw materials, so that not only is the problem of discharge of the waste solved, but also the suspendability of the coating is improved, and comprehensive utilization of the blast furnace slag is achieved. Therefore, the alcohol-based foundry coating has strong market competition ability as well as promotion and application values.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a blast furnace slag 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, whic...
