Embodiment 1

[0025] A high-impact, oil-resistant modified recycled ABS material comprising the following components by weight ratio:

[0026]

[0027] The preparation method of the above-mentioned high-impact, oil-resistant modified regenerated ABS material comprises the following steps:

[0028] (1) Dry the PET at 110-120°C for 4 hours;

[0029] (2) Dry the regenerated ABS at 80°C for 8 hours;

[0030] (3) PET processed through step (1), regenerated ABS processed through step (2), high rubber powder, SEBS-MAH, calcium stearate, nano BaSO 4 , the antioxidant is added to the high-speed mixer according to the weight ratio and mixed, and stirred at room temperature for 10-15 minutes;

[0031] (4) Put the above-mentioned mixture into a twin-screw extruder, and melt, knead, extrude, cool, dry, and pelletize at a temperature of 80-220°C and a screw speed of 350-450 rpm. , Packaging to get the product.

Abstract

The invention discloses a high-impact greasy-dirt-resistant modified regenerated ABS material and a preparation method thereof. The modified regenerated ABS material is prepared from, by weight, 78%-85% of regenerated ABS, 2%-5% of PET, 8%-10% of ABS, 1%-2% of compatilizer, 0.3%-0.8% of lubricating agent, 0.4%-0.8% of antioxygen and 2%-5% of filler. The PET resin, nano BaSO4 and ABS of the specific content are added, the impact resistance and greasy dirt resistance of the ABS material are improved, the use requirement of the ABS material as a high-impact greasy-dirt-resistant storage battery shell is met, impact strength is improved due to rubber toughening of the ABS, and the PET resin and nano BaSO4 achieve the functions of improving the surface polarity of the ABS material and reducing surface microdefects of the ABS material.

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...
