Abstract

The invention discloses an anti-UV LED lampshade. The LED lampshade is prepared from raw materials in pars by weight as follows: 70-80 parts of PP, 20-30 parts of PMMA, 3-5 parts of a coupling agent,2-3 parts of a flame retardant, 2-3 parts of an anti-UV agent, 1-2 parts of an antioxidant and 3-5 parts of a filling agent, wherein the anti-UV agent is prepared from 70-80 parts by weight of a benzotriazole UV absorbent, 20-30 parts by weight of phenyl salicylate, 15-25 parts by weight of zinc borate, 5-10 parts by weight of zinc oxide, 4-10 parts by weight of magnesium hydrate and 5-10 parts byweight of cerium oxide. According to the anti-UV LED lampshade, a main body of the LED lampshade is produced by combination of PP and PMMA, meanwhile, with adoption of the coupling agent, the flame retardant, the anti-UV agent, the antioxidant and the filling agent, dispersing performance of the LED lampshade can be obviously improved, light transmittance and haze are obviously improved, and mechanical property and surface hardness are remarkably improved.

Description

technical field [0001] The invention relates to an LED lampshade, in particular to an anti-UV LED lampshade and a preparation method thereof. Background technique [0002] LED light sources have the advantages of small size, low power consumption, long service life, high brightness, and environmental protection, and are more and more popular among people. LED lampshade is a kind of LED accessories. Its function is to better gather light, make the light more concentrated and softer, and avoid direct glare of LED light. In addition to high light transmission and high diffusion properties, LED lampshades also need high flame retardancy and high impact strength to benefit the life and safety of LED lamps. [0003] However, most of the existing LED lampshades are made of PC, but the PC material LED lampshades have poor heat resistance and low UV resistance. Therefore, it is necessary to propose a novel UV-resistant LED lampshade and a preparation method thereof. Contents of th...
