Abstract

The invention relates to a production method of paint and in particular relates to a production method of an alcohol-based flow coating paint for cast iron. The production method of the alcohol-based flow coating paint for the cast iron comprises the following steps: adding a dissolved rosin liquid and a pretreated bentonite liquid into a dispersing kettle, then sequentially adding ethanol, a combustion-supporting agent, isopropyl alcohol and a thickening agent in residual content, carrying out electric stirring, sequentially adding polyvinyl butyral, a silicate composite suspending agent, a defoaming agent and a surface active agent into the dispersing kettle, regulating the stirring rate to be 500r / min after charging is finished, sequentially adding flake graphite and mullite into the dispersing kettle, regulating the stirring rate after charging is finished, dispersing, sequentially adding quartz powder and white corundum into the dispersing kettle, regulating the stirring rate to be 1200r / min after charging is finished, dispersing for 20 minutes, and discharging. The production method of the alcohol-based flow coating paint for the cast iron is unique, and the produced alcohol-based flow coating paint for the cast iron has the advantages of superior liquidity, good levelling property, high suspension stability, heat shock crack resistance, high temperature stability, sand burning resistance and low gas-forming property.

Description

technical field [0001] The invention relates to a production method of paint, in particular to a production method of alcohol-based flow coating for cast iron. Background technique [0002] With the continuous development of the market economy, users have higher and higher requirements for the dimensional accuracy and appearance quality of castings. However, due to the low quality of the coating, the surface of the castings has obvious brush marks and the edges and corners of the shape are not clear, so the surface roughness of some castings does not meet the requirements, and there are surface defects, which affect the advantages of the product in the market competition. By improving the coating quality and adopting the flow coating process, the surface quality of the casting has been greatly improved. [0003] The flow coating process was seen in the United States, Western Europe and other countries in the 1980s. It is a rapid application process for paint. The flow coat...
