Abstract

The invention discloses a high-impact, oil-resistant modified and regenerated ABS material and a preparation method thereof. The modified recycled ABS material of the present invention comprises the following components by weight: 78-85% of recycled ABS, 2-5% of PET, 8-10% of high rubber powder, 1-2% of compatibilizer, and 0.3% of lubricant ‑0.8%, antioxidant 0.4‑0.8%, filler 2‑5%. In the present invention, by adding specific content of PET resin, nanometer BaSO4, and high rubber powder, the impact resistance and oil resistance performance of ABS can be improved, and the requirements for use as a high-impact and oil-resistant battery shell can be met, wherein the rubberization of high rubber powder increases Toughness improves impact strength, PET resin and nano-BaSO4 play a role in improving the polarity of ABS surface and reducing surface microscopic defects.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-impact, oil-resistant modified recycled ABS material and a preparation method thereof. Background technique [0002] ABS resin is a graft copolymer of acrylonitrile, butadiene and styrene. The styrene component in ABS resin provides good processability, the acrylonitrile component contributes to the strength and chemical resistance of the resin, and the butadiene component brings good impact properties to the resin. Because ABS resin has the advantages of good impact resistance, processability, dimensional stability, low temperature resistance, electrical insulation performance, wear resistance and chemical corrosion resistance, it is widely used in parts of automobiles, electronics, electrical appliances, office equipment and other industries and casing. A large number of applications of ABS in the above-mentioned fields, especially in the past five years, a l...
