Problems solved by technology

Chinese patent application No. 201010224699.1 is limited to LED lamp shades, and uses the traditional extrusion granulation processing method to start with the problem
Once yellowing occurs and the color of the material becomes darker, it will inevitably absorb light energy, resulting in the loss of light energy
In the prior art, there is no research on the yellowing of ABS low-shading materials after long-term use in high-temperature environments

Abstract

The invention relates to the technical field of polymer alloy materials, and in particular relates to an anti-yellowing and low transmittance acrylonitrile-butadiene-styrene / polycarbonate alloy material and a preparation method thereof. The material is prepared from the following components in parts by weight: 55 to 69 parts of ABS resin selected from acrylonitrile-butadiene-styrene resin produced by an emulsion grafting method, 10 to 25 parts of polycarbonate, 6 to 11 parts of flexibilizer, 3 to 15 parts of light diffusion agents, 2 to 15 parts of light blocking agents, 0.5 to 2 parts of light stabilizer and 0.5 to 2 parts of processing agents, and the components are evenly mixed, sent into an internal mixer for mixing, pressed into 1 to 5-mm sheets with a film pressing machine, and then cut into pellets with a knife. The dispersion effect of the material components is good and uniform, the material has excellent low transmittance in thinner pieces, and has excellent performance of resisting yellowing when working in a high temperature environment for a long time. The yellowing-resisting and low transmittance acrylonitrile-butadiene-styrene or polycarbonate alloy material is suitable for optical components in the fields of illumination, electronic appliances, automobiles, aviation and the like.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of polymer alloy materials, and specifically relates to an acrylonitrile-butadiene-styrene / polycarbonate alloy material with the advantages of yellowing resistance, low light transmittance and the like and a preparation method thereof. [0003] (2) Background technology [0004] Acrylonitrile-butadiene-styrene composition (ABS for short) is a graft copolymer of three monomers: acrylonitrile, butadiene and styrene. Because it combines the chemical resistance and high surface hardness of acrylonitrile, the toughness of butadiene, and the coloring and good processability of styrene. [0005] Optical products with high added value, such as automotive lampshades, LED lampshades for lighting, LED display frames, display screen frames, and mobile phone frames in the field of electronic appliances, have higher and higher requirements for lighting. For example, LED lampshades and dashboard instrument lamps...
