Abstract

Vanadium iron slags, corundum slags, magnesite, kaoline, silicon carbide, zinc-aluminum oxide spinel fine powder, brucite, glass powder, sea-foam stone powder, siliceous shale powder, isocyanate propyl group triethoxy silane, isopropoxy tri-(dodecylbenzene) titanate, isobutanol etherified melamine methyl ether resin, dicumyl peroxide, polyethylene alcohol ether, tert-acetic emulsion, asbestos fiber, starch, sodium dodecyl sulfate, pentaerythritol, sodium benzoate, ethanol and water are used as raw materials, and a coating with the good using performance and low production cost for lost foam casting is obtained. The purposes of comprehensively recycling the vanadium iron slags and the corundum slags and lowering the 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-corundum slag 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 (such as intake ...
