Abstract

The invention discloses a polyester resin-based light scattering composite. The polyester resin-based light scattering composite is prepared by mixing the following raw materials by weight: 100 parts of matrix resin, 0.3 to 1.5 parts of a light scattering agent, 0.1 to 0.6 part of an anti-oxidant and 0.1 to 0.5 part of a release agent. The matrix resin is composed of, by weight, 30 to 90% of polycarbonate and 10 to 70% of polyterephthalate, wherein polyterephthalate is one or more selected from a group consisting of PET, APET and PETG. According to the invention, the advantages of a plurality of resins are comprehensive utilized and give to full play, so the disadvantages of gap sensitivity, poor resistance to organic chemicals and the like of PC resin used in traditional LEDs are overcome; and cost for light scattering materials used for LEDs is substantially reduced, which exerts active promotion effect on application of LED illumination systems to houses of ordinary people so as to allow ordinary people to enjoy convenience brought by modern science and technology.

Description

technical field [0001] The invention relates to a light-diffusing composite material, in particular to a polyester resin-based light-diffusing composite material. Background technique [0002] LED lighting products have the characteristics of energy saving, environmental protection, and long service life, and their application prospects are very optimistic. According to PIDA forecast, the LED lighting market will maintain a rapid growth until 2016, when the global LED bulb market capacity can reach 5.6 billion per year. The high-performance light diffusion material can be widely used in light scattering and uniform light components of LED lamps, such as bulbs and lamp tubes of LED bulbs, light diffusion panels with large LED panels, astigmatism components of LED downlights, etc. In order to improve the light quality of the LED light source, ensure the luminous efficiency of the LED, and reduce the overall cost of the LED light source. [0003] 1) Polycarbonate (Polycarbona...
