Abstract

The invention discloses a low-temperature-brittleness modified acrylonitrile-butadiene-styrene copolymer. The low-temperature-brittleness modified acrylonitrile-butadiene-styrene copolymer is preparedfrom the raw materials of, in parts by weight, 100-140 parts of acrylonitrile-butadiene-styrene copolymers, 40-60 parts of polytetrafluoroethylene, 4-6 parts of di-tert-butyl hydrogen peroxide, 1-2 parts of 2,4,6-tri(dimethylamine)phenol, 2.5-4.5 parts of silane coupling agents KH-570, 15-25 parts of hollow glass beads, 10-18 parts of vermiculite powder, 6-12 parts of mica powder, 12-20 parts ofprecipitated barium sulphate, 10-18 parts of polyurethane rubber, 4-8 parts of calcium sorbate and 4-8 parts of sodium dodecyl benzene sulfonate. The low-temperature-brittleness modified acrylonitrile-butadiene-styrene copolymer is good in low temperature brittleness, good in anti-aging effect, high in structural strength and high in anti-impact strength, and is suitable for parts in the field ofautomobiles.

Description

technical field [0001] The invention relates to the technical field of plastics, in particular to a modified acrylonitrile-butadiene-styrene copolymer with low low-temperature brittleness. Background technique [0002] Acrylonitrile-butadiene-styrene copolymer (ABS resin) has the advantages of high toughness, dimensional stability, chemical stability, thermal stability and lubricating properties, and is suitable for making automobile body panels, automobile side guards, and fenders , automotive door frames, etc., gear boxes, automotive bumpers, and products that require chemical resistance and corrosion resistance, thermal stability, impact resistance, and geometric stability. [0003] However, the toughness of ABS resin plastic alloy will be greatly affected by temperature, and generally manifests as low-temperature brittleness. Therefore, the plastic is modified to improve its low-temperature resistance performance, so as to broaden the application field of plastic. Cont...
