BUMPER PAINT HAVING SILVER POWDER EFFECT AND NO SHIELDING EFFECT ON AUTOMOBILE RADAR AND PREPARATION METHOD

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 m
