Abstract

The invention discloses a calcined quartz powder casting coating and a production method thereof. The calcined quartz powder casting coating comprises the following components: 80-100 parts of quartz powder, 0-50 parts of corundum powder, 0-100 parts of mullite powder, 0-30 parts of bauxite powder, 0-100 parts of zircon powder, 0-10 parts of flake graphite, 0-20 parts of earthy graphite, 0-5 parts of red iron oxide, 6-8 parts of a suspension, 5-8 parts of resin and an appropriate amount of a solvent. The production method comprises the following steps: adding the suspension, the resin and the appropriate amount of solvent in a blender to be stirred for 10-30 minutes, then adding quartz powder, alumina powder, mullite powder, bauxite powder, zircon powder, flake graphite, earthy graphite, and red iron oxide to be stirred for 30-60 minutes, adding the appropriate amount of solvent to be adjusted to an appropriate proportion to obtain the casting coating. According to the calcined quartz powder casting coating and the production method thereof provided by the invention, the calcined quartz powder is used as a refractory material to produce the coating, and the resource of quartz powder is rich, so that the problem of lack of resources is solved; the cost is greatly reduced, the product quality is improved, the market competitiveness is strong and the popularization and application value is high.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to a calcined quartz powder 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 The dispersion system composed of different materials 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, which can be roughly divided into two types...
