Abstract
The invention relates to frosting resin, in particular to PC (polycarbonate) frosting resin and a preparation method thereof, and is intended to solve the problems that the prior art has improved glass frosting effect, while coating of polyurethane frosting paint is required to arrive at frosting, the technique is complex, and the quality is difficult to guarantee. The PC frosting resin is characterized by comprising, by weight, 80-97 parts of PC resin, and 3-20% of organosilicon microspheres; the above ratio helps increase the refractivity of PC resin to 1.61-1.74 and decrease light transmittance by 5-12%; light from an LED lamp is softer with higher intensity and good toughness; the formula is simple, preparing is easy, the cost is low, and the needs of consumers are better met.
Description
technical field [0001] The present invention relates to frosting resin, more specifically, it relates to PC frosting resin and its preparation method. Background technique [0002] Generally speaking, frosting is a process of making an object with a smooth surface rough, so that light irradiates on its surface to form a diffuse reflection, and the resulting product becomes a frosted product. [0003] In order to achieve the effect of soft light, the lamps and lanterns usually use frosted glass or resin, but the production of frosted glass or resin by mechanical processing methods, such as sandblasting, is not only labor-intensive, but also the effect is not ideal. [0004] In view of the above problems, at present, the Chinese patent with the publication number CN103342952A discloses a polyurethane resin frosted coating and a preparation method thereof. Spray it on cleaned glass and bake it to get a frosted effect. [0005] Although the above solution improves the frosting...
