Problems solved by technology

The disadvantage of ABS resin is that its light transmittance is low
Although the light transmittance of the ABS composite material prepared by this prior art has been improved to a certain extent, the light transmittance is still not high enough, the astigmatism is poor, the haze value is low, and the shading performance is poor, which cannot meet the requirements of the outer cover for LED lighting fixtures. High light transmission and high shading requirements for materials

Abstract

The present invention relates to the technical field of ABS materials, in particular to a high light-transmitting, high-shading ABS material, comprising the following raw material components in mass percentages: 93.0-99.5% ABS resin, 0.1-0.6% antioxidant, 0.1-2.3% organic Silicone resin light diffusing agent; the antioxidant is one or a mixture of antioxidant 1076 or antioxidant 168; the sum of the mass percentages of the above components is 100%. The preparation method is as follows: first put the antioxidant and the silicon-based light diffusing agent into a high-speed mixer and stir evenly, then add ABS resin for three-stage mixing, and finally put the evenly mixed material into a twin-screw extruder for extrusion Pellet out to make ABS material. The ABS material of the present invention has good light astigmatism performance, can achieve the balance of haze and light transmittance at the same time, meets the requirements of the outer cover of LED lighting lamps, has a simple preparation method, and is favorable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ABS material with high light transmission and high light shielding and a preparation method thereof. Background technique [0002] Light-emitting diodes (Light Emitting Diode, LED) are increasingly widely used in the fields of display, transportation, electrical appliances and lighting due to their small size, long life, rich color rendering and outstanding energy-saving and environmental protection characteristics. , one of the key technologies for cleaner production and sustainable development. [0003] Due to its light-emitting characteristics of point light sources and high brightness, LEDs have disadvantages compared with conventional light sources such as strong light, glare, people can't look directly, or can't get soft visual effects in the field of lighting. In order to make up for the lack of application of LED light sources in the field of lighting, it is...
