[0004] Chinese patent CN 106221172 B "A Low Warpage Reinforced PC / ABS Alloy Material and Its Preparation Method" discloses a low warpage reinforced PC / ABS alloy material, which changes the orientation of glass fibers by adding four-needle zinc oxide whiskers, reducing the The degree of orientation of the glass fiber along the flow direction reduces the shrinkage difference between the flow direction of the part and the vertical flow direction, and reduces the warpage. However, the material does not have a low-odor effect

Abstract

The invention discloses an ABS (Acrylonitrile Butadiene Styrene) composite material as well as a preparation method and application thereof, and relates to the field of modified plastics. The ABS composite material is prepared from the following components in parts by weight: 40 to 55 parts of ABS resin, 25 to 45 parts of flat glass fiber, 10 to 20 parts of random copolymer SMA and 2 to 5 parts of synergist, wherein the flatness ratio of the flat glass fibers is 4-6; the synergist is shell powder. According to the invention, the ABS resin, the flat glass fiber, the random copolymer SMA and the synergist are optimized, so that the ABS composite material with low warpage and low odor is provided.

Description

technical field [0001] The invention relates to the field of modified plastics, in particular to an ABS composite material and a preparation method and application thereof. Background technique [0002] ABS resin (acrylonitrile-butadiene-styrene copolymer) has the advantages of high rigidity and high impact strength, and is widely used in household appliances, lighting equipment, office equipment, auto parts and other fields. However, ABS resin also has shortcomings. ABS materials generally have a relatively strong odor, and ordinary glass fiber-reinforced ABS has a general warpage. [0003] LED display screens are widely used in indoor office presentations, outdoor advertising and video playback, and are an important communication medium. LED display screens are generally assembled by modules, and LED modules are composed of PCB boards, LED brackets, LED lights and LED masks. Among them, the LED bracket material has a great influence on the flatness of the entire display ...
