Problems solved by technology

[0006] At present, the low light transmittance of acrylonitrile-butadiene-styrene in the existing technology is mostly from the large amount of ABS (such as the invention patent of Chinese patent application number 201210221191.5), or the narrow optional range of ABS (such as Chinese patent Patent of invention with application number 201310267948.9), or traditional extrusion granulation processing method (such as patent of invention with application number of Chinese patent 201310267948.9) to deal with the problem
At the same time, the prior art only discloses light-shielding explanations for thicker products (for example, the Chinese patent application number 201310267948.9 is a 2 mm thick light-shielding material)
[0007] There are some deficiencies: ①The solution to the low light transmittance of thinner products is not effective; ②The range of conditions for ABS resin selection is not completely resolved; ③Light diffusing agents and light blockers that reduce light transmittance have no clear selection targets; ④ The heat resistance problem of ABS with low light transmittance is not solved; ⑤The traditional extrusion granulation processing method does not effectively improve the dispersion effect of light diffusing agent and light blocking agent in resin

Abstract

The invention belongs to the technical field of high molecular materials and relates to high-heat-resistant low-light-transmittance acrylonitrile-butadiene-styrene composition and a preparation method thereof. The composition is prepared from the following ingredients in parts by weight: 55 to 74 parts of acrylonitrile-butadiene-styrene resin which is chosen from emulsion grafting method production, 0 to 12 parts of acrylonitrile-styrene, 10 to 20 parts of heat-resisting agent, 3 to 15 parts of light diffusion agent, 2 to 15 parts of light blocking agent, 0.5 to 2 parts of light stabilizer and 0.5 to 2 parts of processing aid. All the ingredients are evenly mixed and then sent into an internal mixer to be extruded and mixed, are compressed into 1 to 5-millimeter slices by a laminator and then are cut into a particle material by a cutter. The material has a good and uniform-phase ingredient dispersion effect, has excellent low light transmission in thinner work pieces, further has good heat resistance and is suitable for being applied to optical components in the fields of electric appliances, automobiles, aviation and the like.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of polymer materials, and in particular relates to an acrylonitrile-butadiene-styrene composition with the advantages of high heat resistance and low light transmittance 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 of its combination of chemical resistance and high surface hardness of acrylonitrile, toughness of butadiene, coloring and good processability of styrene, it is widely used in appearance parts in household appliances, automobiles, aviation and other fields. [0005] At present, with the continuous development of science and technology, optical products with high added value, such as automotive lampshades, SLR camera hoods, LED lampshades, LED display frames, display frames, and mobile phone frames, have higher a...
