Document Type and Number:
WIPO Patent Application WO/2020/135057
Kind Code:
A1
Abstract:
The present invention relates to bumper paint having silver powder effect and no shielding effect on an automobile radar and a preparation method thereof. The bumper paint is prepared by the raw materials with the following components in parts by weight: 18-28 parts of wax additive, 6-9 parts of acrylic resin, 2-5 parts of modified polyester, 5-6 parts of amino rheological agent, 40-45 parts of cellulose acetate, 0.2-0.5 parts of flatting agent, 8-10 parts of solvent, 6-9 parts of sheet mica, and 0.2-0.5 parts of dispersing agent. Compared with the prior art, the bumper paint uses special sheet mica having silver powder effect as a pigment, and can exhibit a variety of silverysheens that are delicate, soft and sparkling by utilizing light refraction and transmission; and since pure natural sheet mica is used as the raw material, the paint has characteristics such as non-toxic, high temperature resistance, acid and alkali resistance, light resistance, non-conductivity and the like, and can completely replace metal aluminum powder pigment to be directly constructed on the bumper, and has no shielding effect on automotive radar.
