Abstract

An expendable pattern casting coating superior in using performance and low in production cost is prepared with high-aluminum blast furnace slag, high-magnesium phosphate tailings, quartz milltailings, pyrite tailings, attapulgite, silicon carbide, kaolin fine powder, siliceous shale powder, diaspore, silicon boride, thorium dioxide, gamma-(methylacryloyl oxygen base) MAPTMS, 2-(phosphorous acid 2-glycerol trilaurate) 4-oxygen octyloxy titanate, isooctyl palmitate, dicumyl peroxide, polyving akohol, hydroxy propyl distarch phosphate, carbon fiber, sodium gluconate, petroleum sodium sulfonate, neopentyl glycol, ethanol and water as raw materials. The purposes of comprehensively recycling high-aluminum blast furnace slag and high-magnesium phosphate tailings and reducing the production cost are achieved.

Description

technical field [0001] The invention belongs to the field of lost foam casting coatings, in particular to a high-alumina blast furnace slag-high magnesium phosphorus tailings 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 cas...
