Anhydrous water-base forsterite powder paint

Abstract

The anhydrous water-base forsterite powder paint has the main components of forsterite powder, white latex, suspending agent, dextrin, and sodium carboxymethyl cellulose. Through adding forsterite powder and other matter, mixing and grinding, the powder paint is made to í‹matureíŒ, homogenize, disperse, swell, increase in specific surface and become favorable to form film. The present invention can raise the suspension performance and stability of paint, reduce fermentation, and make the casting produced with the paint no chemical sand adhesion and easy to clean. The present invention is especially suitable for use in producing casting of high manganese steel, stainless steel and other high alloy steel to result in excellent use effect.

Description

technical field

[0001] The invention relates to a powder coating, in particular to an anhydrous water-based forsterite powder coating and a preparation method thereof. Background technique

[0002] The water-based coating for lost foam casting is one of the essential key materials in the lost foam casting process. There are two main sources of coatings for foundries: one is the finished paste water-based coating. Paste coating not only increases packaging cost, but also brings inconvenience to transportation. In particular, any slurry or paste water-based paint contains a certain amount of organic particles. Organic matter soaked in water for a long time will more or less produce tiny bubbles due to fermentation. The bubbles remain in the suspended slurry and directly affect the coating. use effect. In order to prevent the fermentation phenomenon caused by long-term storage of paint, it is necessary to add highly toxic preservatives, which will cause great harm to human sk...
