Abstract

The invention discloses a PU elastic paint, which comprises a main paint, a curing agent and a diluent, wherein the main paint comprises 27 to 35 percent of elastic resin, 0.2 to 1 percent of drier, 1 to 3 percent of elastic powder, 5 to 7 percent of matting agent, 50 to 60 percent of solvent and 1 to 4 percent of organic silicon assistant. The elastic paint disclosed by the invention is easy in construction, the spraying thickness exerts little affect on the luster of the paint film, and the paint film offers a full handfeel and has a soft luster and uniform chroma.

Description

Technical field [0001] The invention relates to a paint, in particular to a PU elastic paint. Background technique [0002] Paint is an indispensable decorative material in modern life. PU paint is a kind of paint with a large amount and a wide range in modern paint, which gives decoration and protection. [0003] Elastic paint, also known as hand-feel paint, is a PU two-component paint with flexible polyester as the main raw material and aliphatic isocyanate curing agent. Mainly used on ABS, PC and other substrates, especially suitable for the coating of some mobile phones, computers, mice, microphones and other products. The existing elastic paint takes a long time to bake during painting, and it is easier to have uneven color tone and blooming. Summary of the invention [0004] The invention provides a PU elastic paint, which solves the problem that the existing PU elastic paint is prone to blooming. [0005] A PU elastic paint comprising a main paint, a curing agent and a dilue...
