Abstract

The invention discloses a high aluminum powder casting coating. The high aluminum powder casting coating comprises the following components in parts by weight: 25-35 parts of methyl alcohol, 10-18 parts of acrylate, 40-65 parts of high aluminum powder, 5-8 parts of copper powder, 1-2 parts of phenolic resin, 1-2 parts of lithium-based bentonite, 0.05-0.08 part of polyvinyl butyral, and 0.3-0.5 parts of fatty alcohol-polyoxyethylene ether. The benefits are as follows: the high aluminum powder casting coating is strong in chemical stability and not easy to deform; besides, the coating is not adhered to the material as the viscosity of the high aluminum powder casting coating is far lower than that of the conventional product, the surface integrity of a casting cavity or a sand core can be ensured, and the smooth degree of the product is improved.

Description

technical field [0001] The invention relates to the field of casting, in particular to a high-aluminum powder casting coating. Background technique [0002] Foundry coatings refer to casting auxiliary materials used to coat the surface of cavity or sand core to change their surface refractoriness, chemical stability, metal erosion resistance, sand sticking resistance and other properties. Traditional casting coatings have weak chemical stability and high viscosity, and are easy to stick to materials during production, so they are not suitable for large-scale industrial production. Contents of the invention [0003] The object of the present invention is to provide a high-alumina powder casting coating with strong chemical stability and low viscosity for the above-mentioned defects in the prior art. [0004] In order to achieve the above object, the technical solution provided by the present invention is: a high-alumina powder casting coating, including the following compo...
