Technical Field
With the increasingly better living conditions, people have more and more demands on clothes, so that the demands on small alloy parts such as zipper heads and the like are also increased. The surface treatment of common spraying, curtain coating and dip coating processes cannot be adopted due to the small volume, large specific surface area and the like of small alloy parts such as the zipper head. The most common painting method in the industry for small alloy pieces such as zippers is roll-on painting. The traditional roll-painting paint is generally an oily acrylic resin system, an oily epoxy resin system and the like, and the used diluent is an oily solvent such as sky blue water, toluene, xylene and the like. These oily solvents are harmful to human bodies and are not environmentally friendly. The temperature of the roller spraying painting is generally 90-130 ℃, the flash point of the oily solvent is low, flash explosion accidents are easy to occur, and the damage to the bodies of operators and the surrounding environment is great. The product sprayed by the traditional oily roller painting roller is rough in surface, low in gloss and very cheap.
Therefore, how to overcome the defects that the existing oily roller painting is not environment-friendly and unsafe and the surface quality of the prepared product is poor is a problem to be solved in the industry.
