Abstract

The invention discloses a regenerative PETG / PC alloy light diffusion material and a preparation method thereof. The regenerative PETG / PC alloy light diffusion material is prepared from, by weight, 80-92 parts of PETG regenerative material, 8-20 parts of PC, 0.2-2 parts of light diffusion agent, 0.2-2 parts of antioxidant and 0.2-2 parts of lubricating agent. PETG / PC alloy is adopted to serves as a light diffusion substrate, enough light transmittance can be guaranteed, and meanwhile the heat deformation temperature is increased to 80 DEG C or above; the requirement of an LED lamp for the heat deformation temperature of the light diffusion material is met, the advantages of other light diffusion materials are achieved, the regenerative PETG / PC alloy light diffusion material is not prone to friability, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a recycled PETG / PC alloy light diffusion material and a preparation method thereof. Background technique [0002] With the development of LED lighting technology and market, various lamps based on LED light sources have been applied in various fields. LED light sources have strong luminous intensity and good lighting effects, but they are very dazzling, especially in indoor environments, which can easily cause people's visual fatigue and visual impairment. Therefore, there is a need for a substrate that can satisfy the high light transmittance of the LED and prevent the line of sight from directly contacting the light source. At present, the base materials of existing light diffusion materials on the market are generally PC, PMMA, PS, PP, etc., but there are certain defects, such as PMMA and PS are brittle and can only be made into light diffusion plates, and the shrin...
