Sesame sauce residue/coal gangue compounded alcohol group casting paint and preparation method thereof

Abstract

The invention discloses sesame sauce residue / coal gangue compounded alcohol group casting paint and a preparation method thereof. The sesame sauce residue / coal gangue compounded alcohol group casting paint is characterized by being prepared from the following raw materials in parts by weight: 70-95 parts of corundum powder, 1.1-2.3 parts of titanium oxide, 2-3 parts of chromium oxide, 20-30 parts of cordierite, 25-35 parts of coal gangues, 0.4-0.6 part of sodium antimonite, 1-4 parts of graphene, 13-17 parts of sesame sauce residues, 1-2 parts of bentonite, 5-8 parts of polyvinyl alcohol carboxyl butyraldehyde, 45-60 parts of alcohol and 3-6 parts of auxiliaries. According to the sesame sauce residue / coal gangue compounded alcohol group casting paint disclosed by the invention, the sesame sauce residues and the coal gangues are modified and compounded and then are added into raw materials, so that not only can various comprehensive performances of the paint be strengthened, but also the environment is protected and the cost is lowered, and therefore, the paint has extremely high economic benefits and social benefits. The paint prepared by adopting the preparation method disclosed by the invention can reach the effects of the casting paint, and can realize the comprehensive utilization and cyclic utilization.

Description

technical field [0001] The invention relates to the field of casting coatings, in particular to an alcohol-based casting coating compounded with sesame paste residue / coal gangue 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 ...
