Abstract
The invention discloses an anti-aging photodiffusion PC (Poly Carbonate)-based resin which is prepared from the following raw materials in parts by mass: 95-98 parts of PC aggregates, 2-4 parts of PC powder, 0.5-2 parts of photodiffusant, 0.02-0.05 part of antioxidant and 0.005-0.01 part of UV (Ultraviolet) assistant. A preparation method of the anti-aging photodiffusion PC-based resin comprises the following steps: 1) mixing the PC powder, the photodiffusant, the antioxidant and the UV assistant for 5-10 minutes through a high mixing machine to obtain a mixture; and 2) placing the mixture obtained in the step 1) with the PC aggregates in a low mixing machine to be stirred and mixed for 5-10 minutes, and then placing in an extruder to be subjected to melt extrusion, and pelleting. The anti-aging photodiffusion PC-based resin disclosed by the invention has relatively high light transmittance, good ageing resistance and high notch impact strength, and the product obtained has good comprehensive performance.
Description
Technical field
The present invention relates to a kind of anti-aging light diffusion PC base resin and preparation method thereof.
Background technology
In present LED Lighting Industry, lampshade and fluorescent tube generally adopt PC and the blend of scattering of light auxiliary agent to form, due to problems such as disperse phase capacitives, be difficult to take into account mist degree and the light transmission of material, the shock strength of material is also lower, and after using for some time, there is flavescence phenomenon in product.Have a strong impact on lighting effects, light fixture is shortened work-ing life on the whole.
The material using now, due to problems such as disperse phase capacitives, the shock strength of material is on the low side, and melting index is little, injection moulding demoulding difficulty, production efficiency is low.
