Abstract

The invention relates to a polyurethane black smooth-faced hammer paint, which is characterized in that the paint is composed of the following ingredients (by weight): 67-73% of 1000H polyester, 0.4-0.6% of a catalyst, 4-6% of a curing agent, 20-24% of enriched precipitated barium sulphate, 0.1-0.3% of wax powder, 0.3-0.5% of a micronized wax defoamer, 0.2-0.4% of a leveling agent, 0.4-0.6% of a friction charging agent, 0.5-0.7% of carbon black, and 0.5-0.7% of a moire agent. With the1000H polyester, the catalyst and the curing agent, the polyurethane black smooth-faced hammer paint has good fineness and high weather resistance, and brightness of the coating is enhanced. With the moire agent, the powder has good texture, the texture is more uniform, and the three-dimensional visual effectof the coating is better.

Description

technical field [0001] The invention relates to the field of hardware coatings, in particular to a polyurethane black cotton paint and a preparation process thereof. Background technique [0002] Hardware materials are generally coated with a layer of paint on the surface to protect the metal, but the coating of existing hardware materials has poor weather resistance and cannot play a good protective role. The coating has low brightness and uneven texture, resulting in The stereoscopic effect is poor, and the appearance is not beautiful. Contents of the invention [0003] In order to solve the above problems, the present invention provides a polyurethane black cotton paint with good weather resistance, good brightness and uniform graining and its preparation process. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: a kind of polyurethane black cotton paint, its composition content is: [0005] [0006] ...
