Abstract
A disclosed composite material used for LED lampshades is composed of the following compositions in parts by weight: 50-80 parts of PC (polycarbonate), 10-30 parts of nanometer TiO2, 0.2-0.5 part of a flexibilizer, 0.5-2 parts of an anti-oxidant, 1-3 parts of a light diffusion agent, 0.1-2 parts of an ultraviolet ray absorber, and 5-10 parts of a blending agent. The composite material is formed by improving a PC material, possesses good light-ageing resistance, possesses various physical mechanical performances and thermodynamic properties which are basically not influenced, and has wide application prospect.
Description
Technical field
The present invention relates to a kind of matrix material for LED lamp cover, belong to technical field of polymer materials.
Background technology
PC (polycarbonate) has excellent shock resistance, creep resistance, dimensional stability and electric insulating quality, a kind of engineering plastics of superior performance, be widely used in the fields such as mechanical means, electronic product, automobile making, but also there is poor fluidity, easily stress cracking, the easily aging and shortcoming such as to wear no resistance, its application is in a lot of fields restricted.In recent years, along with expanding economy, plasticity and the chemical stability of PC engineering plastics are relatively good, but, when being used as LED lamp cover, owing to being subject to the irradiation of light for a long time, easily causing aging, the demand in market can not be met.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to the defect overcoming prior art, providing a kind of aging-resistant for the matrix material of LED lamp cover.
In order to realize above-mentioned target, the present invention adopts following technical scheme: a kind of matrix material for LED lamp cover, is characterized in that, comprises following component and the parts by weight of each component are:
PC 50-80 part;
