Problems solved by technology

Traditional cast steel materials use expensive zircon powder or graphite powder as the main raw material, and the graphite powder used is heavy in color, easy to dye, and mostly radioactive
Furthermore, after the traditional quartz sand coating is processed at high temperature, the coating is prone to sand sticking and cracking, the surface roughness of the casting is high, it is difficult to meet the quality standard, and the amount of residual waste remains high.

Abstract

The invention relates to a water-based cast steel coating which comprises the following raw materials in parts by weight: 50-70 parts of kyanite powder, 0.5-3 parts of attapulgite, 1-5 parts of magnesium chloride, 0.5-6 parts of barium chloride, 0.2-2 parts of resins, 0.1-3 parts of silica gel and 0.1-3 parts of an emulsifier. The water-based cast steel coating provided by the invention is applicable to brush-coating resin sands and synthesized sand moulds. Magnesium chloride and barium chloride are added into the coating for easy shelling and preventing sand burning, so that the strength of the coating is improved, the resistance of the coating to high temperature molten steel is improved, the roughness on the casting surface is effectively improved, and the quantity of waste products is greatly reduced. The water-based cast steel coating has a greater market prospect.

Description

technical field [0001] The invention relates to a paint, in particular to a water-based cast steel paint. Background technique [0002] In recent years, with the development of China's industry, the requirements for steel materials are getting higher and higher. Traditional cast steel materials use expensive zircon powder or graphite powder as the main raw material, and the graphite powder used is heavy in color, easy to dye, and mostly radioactive. Furthermore, after the high-temperature treatment of the traditional quartz sand coating, the coating is prone to sand sticking and cracking, the surface roughness of the casting is relatively high, it is difficult to meet the quality standard, and the amount of residual waste remains high. [0003] The purpose of the present invention is to overcome the above defects, to produce a novel water-based cast steel coating that is easy to shell, high temperature resistant and sand sticking resistant. The object of the present invent...
