Vanadium iron slag-thermal power plant coal ash evaporative pattern casting coating and preparation method thereof

Abstract

Provided are a vanadium iron slag-thermal power plant coal ash evaporative pattern casting coating and a preparation method thereof. The vanadium iron slag-thermal power plant coal ash evaporative pattern casting coating comprises vanadium iron slag, thermal power plant coal ash, magnesia, diatomite, silicon carbide, high-bauxite fine powder, brucite, tantalum carbide, aluminum nitride, boron nitride, gamma-methacryloxy propyl trimethoxyl silane, tetra-octyl di (phosphate di-butyl laurate) titanate, isobutanol etherified melamine methyl ether resin, dicumyl peroxide, Fatty alcohol polyoxyethylene ether, vac-veova emulsion, carbon fiber, dextrin, sodium alginate, pentaerythritol, sodium benzoate, ethanol and water. The prepared vanadium iron slag-thermal power plant coal ash evaporative pattern casting coating has excellent use performance and is low in production cost, and the purposes of comprehensively recycling the vanadium iron slag and the thermal power plant coal ash and reducing production cost are achieved.

Description

technical field [0001] The invention belongs to the field of lost foam casting coatings, and in particular relates to a vanadium iron slag-fired power plant fly ash lost foam casting coating and a preparation method thereof. Background technique [0002] Lost foam casting technology is a new casting process in the foundry industry. The lost foam casting process refers to making foam plastic (EPS, ETMMA or EPMMA) into the shape, structure and size of the required castings. After the refractory coating is dried, it is embedded in a special sand box with dry sand (usually quartz sand) for molding, and then poured under a certain negative pressure. Lost foam casting is mainly called dry sand solid mold casting and negative pressure solid mold casting in China, and it is referred to as EPC casting abroad. [0003] At present, the most mature lost foam casting process is used in the mass production of automotive castings. The products produced include aluminum alloy castings (suc...

AI Technical Summary

Problems solved by technology

Foreign research on lost foam casting coatings started earlier, and there are already some commercial coatings, but the price is too expensive, resulting in increased production costs, which limits the development of lost foam casting technology to a certain extent

At present, many universities and research institutes in China have carried out research and development work on various aspects of lost foam casting, such as pattern materials, molding processes, coating technology, tooling equipment, etc., and have achieved certain achievements, but compared with foreign countries, there are still relatively large Gaps, such as poor commoditization of coatings
