Abstract

The invention relates to paint special for curtain coating, which comprises the following components in part by weight: 20-55 parts of film forming substance, 30-65 parts of preservative, 5-40 parts of solvent and 0.05-5 parts of drier. Compared with the prior art, the paint special for the curtain coating has the characteristics that: (1) the dryness of a coating is enhanced by reducing the content of epoxy ester resin and increasing the dosage of the drier; (2) in a coating solvent, cyclohexanone is added into dimethylbenzene, so that the volatilization speed is adjustable; and the volatilization speed of a coating solvent system and the dryness of the coating can be adjusted; (3) the paint has excellent corrosion resistance; and (4) the paint has high insulating performance, temperature change resistance and ultraviolet resistance, and is suitable for the curtain coating and outdoor conditions.

Description

technical field [0001] The invention relates to a paint, in particular to a special paint for curtain coating. Background technique [0002] Flow coating is one of the paint construction methods, which is to store the paint in the high-level tank, pour it from above through the nozzle or narrow slit, and shower it on the object to be coated driven by the conveyor in the form of a curtain, forming a uniform coating film. The paint flows back into the container and is pumped to the header tank for recycling. For small batches of objects, manual operation is used to pour paint on the painted objects (commonly known as pouring paint method). After developing into automatic assembly line production, it is called curtain coating. It is suitable for coating flat and strip-shaped materials such as steel sheets, plywood, and plastic sheets produced in large quantities. The thickness of the coating film on the product is controlled by the size of the nozzle or the width of the slit...
