Problems solved by technology

[0002] Due to the limitations of the coating process of colored steel plates and aluminum plates, usually only a flat and uniform coating film surface can be produced after the coating is formed, and most of the coating films with special effects cannot be realized on the flow-type roller coating line. Steel plates and aluminum plates are somewhat insufficient in terms of personalization and aesthetics. Therefore, the development of colored steel plates and aluminum plates in the field of decoration in pursuit of beauty, novelty, and individuality is subject to certain restrictions.

Abstract

The invention relates to a coil coating with imitated velvet effect and a preparation method thereof and the coil coating is a colour paint coating used for colour steel and colour aluminum for architectural decoration. According to the technical scheme provided by the invention, the coil coating with imitated velvet effect comprises the following components in parts by weight: 35-40 parts of branched saturated polyester resin, 0.3-1.5 parts of macromolecular block copolymer, 5-30 parts of coloring pigment, 5-25 parts of filler, 3-5 parts of 100# aromatic solvent, 1-3 parts of cyclohexanone, 1-3 parts of dibasic ester, 5-20 parts of polyester polyol resin, 1-3 parts of enclosed type polyurethane curing agent, 2-5 parts of methylated melamine resin, 0.6-1.8 parts of enclosed type p-toluenesulfonic acid, 0.5-1.5 parts of polyethylene wax, 0.15-1.5 parts of triethylamine or ethylenediamine and 0.3-1.5 parts of fluorine modified acrylic leveling agent. The paint capability of the coating of the invention can fully reach all kinds of requirements of forming and can also meet the requirements of good look, newfangled, personality, and the like.

Description

technical field [0001] The invention relates to a coil paint with velvet imitation effect and a preparation method thereof, which is used for colorful coating paint for architectural decoration and belongs to the field of architectural decoration materials.
