Abstract

The invention relates to a high-temperature-resistant high-metal-effect plastic paint and a preparation method thereof. The preparation method comprises the following steps: sequentially adding 20-30 wt% of acrylic resin A, 20-35 wt% of acrylic resin B, 10-20 wt% of polyester resin, 2-3 wt% of catalyst, 0.2-1.0 wt% of acrylic leveling agent, 0.2-0.8 wt% of organic silicon leveling agent, 0.5-1.0 wt% of weather-resistant assistant and 15-25 wt% of mixed solvent, slowly stirring, and stirring at the high speed of 600-800 rpm for 15 minutes to obtain the high-temperature-resistant high-metal-effect plastic paint. Compared with the prior art, the method enhances the high temperature resistance, high metal effect, wear resistance and other properties of the plastic paint.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to a plastic paint with high temperature resistance and high metal effect and a preparation method thereof. Background technique [0002] At present, with the development of automotive paints, plastic paints that can withstand temperatures within a small range no longer meet people's needs. Some automotive plastic parts work in high-temperature environments for a long time, so high-temperature-resistant plastic paints are more in line with the requirements. [0003] Chinese patent CN102277076A discloses a low-temperature water-based two-component metal effect paint and its preparation method. The metal effect paint includes the following components and parts by weight: water-based resin 25-30, defoamer 2-2.5, cosolvent 5- 6. Dispersant 1.5~2, substrate wetting agent 0.3~0.4, thickener 2~3, aluminum powder 4~6, amine neutralizer 0.5~0.6, deionized water 45~50, curing agent ...
