Abstract

The invention discloses a formula of evaporative pattern casting model coating paint. The evaporative pattern casting model coating paint is composed of white aluminum powder, bauxite, quartz powder, white emulsion, cellulose, anhydrous sodium carbonate, bauxite and adhesives. According to the formula, bubbles are not likely to be generated during casting, and therefore the product glossiness can be good, and no burnt-on sand is generated.

Description

technical field [0001] The invention relates to a formulation of a lost foam model coating paint. Background technique [0002] At present, the mold suitable for the leader of the traditional lost foam: gray cast iron - non-ferrous alloy - ordinary carbon steel - ductile iron - low carbon steel and alloy steel; using conventional technology: foam beads, pre-foaming, appearance Forming and foaming, pattern combination, painting, modeling, pouring, and sand falling; the molds produced in this way have many defects due to the reasons of the mold material itself and the process itself, such as: it is easy to generate air bubbles during pouring. The gloss of the product is not good and there are more sticky sand. Contents of the invention [0003] In order to solve the problems in the background technology, the present invention provides a lost foam model coating paint and its manufacturing process, thereby solving the technical problems that air bubbles are easily generated d...
