Abstract

The invention relates to a high-impact-resistant low-temperature-resistant stress-cracking-resistant regenerated ABS material and a preparation method thereof. The regenerated ABS material comprises the following compositions in percent by weight: 83-87% of regenerated ABS, 2-4% of a stress-cracking-resistant agent, 1-2% of a compatilizer, 8-10% of a high glue powder, 0.3-0.5 % of a lubricant, and 0.2-0.5 % of an anti-oxidant. By adding the specific stress-cracking-resistant agent metallocene LLDPE or PE-MAH and combining the stress-cracking-resistant agent with the compatibilizer POE-MAH, the compatibility of the matrix resin ABS and the stress-cracking-resistant agent is effectively solved, and also the low-temperature impact resistance and the solvent resistance of the ABS material are substantially improved.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-impact, low-temperature-resistant, stress-cracking-resistant regenerated 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, espec...
