Abstract

The invention provides an attapulgite casting coating with a good suspension property and relates to the field of casting. The attapulgite casting coating is composed of the following raw materials including, by weight, 100-140 parts of quartz sand, 5-9 parts of pearl powder, 11-15 parts of kieselguhr, 5-9 parts of an adsorbing agent, 16-20 parts of a suspending agent, 2-5 parts of a surface active agent, 3-6 parts of an accelerant, 4-10 parts of attapulgite, 5-9 parts of sodium hydrogen phosphate, 3-6 parts of bentonite, 4-8 parts of sodium benzoate, 3-7 parts of resin, 0.5-3 parts of normal propyl alcohol, 6-14 parts of carboxymethyl cellulose, 0.5-0.9 part of ethyl acetate and 0.5-1.8 parts of fatty alcohol-polyoxyethylene ether. By means of the attapulgite casting coating with the good suspension property, the problem that an existing casting coating is poor in anti-erosion property, suspension property, adsorption property, coating wear resistance and chemical stability is solved.

Description

technical field [0001] The invention belongs to the field of casting, and in particular relates to an attapulgite casting coating with good suspending properties. Background technique [0002] Foundry coatings refer to casting auxiliary materials used to coat the surface of mold cavity or sand core to change their surface refractoriness, chemical stability, metal erosion resistance, sand sticking resistance and other properties. However, the existing casting coatings have the problems of poor erosion resistance, poor suspension, poor adsorption and poor wear resistance of the coating. [0003] A Chinese patent document published on September 30, 2015, a corundum powder casting coating (authorized announcement number CN103506565B), including the following components by weight: 25-35 parts of methanol, 60-65 parts of corundum powder, rosin 1 -2 parts, 3-8 parts of epoxy resin, 1-3 parts of dicyandiamide, 1-2 parts of lithium bentonite, 0.05-0.08 parts of polyvinyl butyral, 0....
