Problems solved by technology

Patent CN102250462 A discloses a method of using polycarbonate to prepare light-diffusing materials and then to prepare LED lampshades. In this technology, light-diffusing agents such as silicone resin are added to polycarbonate to make the haze of the material reach more than 90%, but the transparent The light rate is only 40%, so it cannot be directly used as a light diffusion material

Abstract

The invention relates to a polycarbonate resin composition with high haze and high light transmittance, and a preparation method thereof, belonging to the technical field of high polymer materials. The polycarbonate resin composition is characterized by comprising the following blended components: a, polycarbonate resin; b, organosilicone resin microspheres; and c, cross-linked copolymer microspheres. On the basis of 100 parts by weight of the component a, the component b accounts for 0.01 to 10 parts by weight while the component c also accounts for 0.01 to 10 parts. The polycarbonate resin composition has haze of no less than 92% and light transmittance of no less than 55%; preferably, the composition has haze of no less than 92% and light transmittance of no less than 59%; and more preferably, the composition has haze of no less than 95% and light transmittance of no less than 59%. The polycarbonate resin composition provided by the invention achieves excellent light scattering effect while saving a great amount of energy, reduces material cost and is easy for industrial large-scale production.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a polycarbonate resin composition with high haze and high light transmittance and a preparation method thereof. Background technique [0002] The current society is short of energy, and the whole society is advocating energy conservation and environmental protection. In terms of lighting, in order to reduce energy consumption, the state has promulgated the "Announcement on Gradually Prohibiting and Selling General Lighting Incandescent Lamps" in 2011, which stipulates that the import and sale of general lighting incandescent lamps of 100 watts and above is prohibited nationwide. Therefore, energy-saving lighting will gradually replace ordinary incandescent lamps in the future. [0003] Due to its high energy conversion rate, low power consumption, long service life, and no heavy metals, LED lights have become a development trend as an energy-saving lighting source and ...
