Problems solved by technology

During construction, it is necessary to add more organic solvents to adjust the paint to a lower viscosity before it can be brushed open, so the thickness of the coating obtained by each brushing is thin, and a large amount of solvents corrode the sand mold, causing harm
[0006] 3. Poor brushing property
The hand feels not smooth when brushing, and the brush feels astringent and tight every time it is dipped in the paint and brushed back and forth several times, which makes the brushing operation time-consuming and laborious, increases the labor intensity of brushing, reduces the brushing efficiency, and cannot meet the requirements of large-scale casting sand molds /Core requirements for large area brushing
[0007] 4. Poor leveling
Due to the poor leveling of the coating, the coating cannot automatically level

Description

technical field [0001] The invention relates to a casting coating, in particular to an alcohol-based zircon powder coating for large castings and a manufacturing method thereof. Background technique [0002] As the basic industry of the country, the heavy equipment manufacturing industry plays a vital role in the national economy. As the core components of national defense, metallurgy, petroleum, chemical industry, power station, nuclear energy and other industries, the quality of large castings is one of the important factors that directly affect the development of these industries. With the continuous development of these industries, the quality of large castings will The level puts forward higher and higher requirements. Applying casting paint on the working surface of the mold (core) is an important process in the production process of large castings. The main functions of the casting paint include: reducing the surface roughness of the casting; preventing and reducing ...
