Abstract

The invention provides an energy absorption and shock absorption PC / ABS alloy and a preparation method thereof. The energy absorption and shock absorption PC / ABS alloy is prepared from the following components in parts by weight: 30-50 parts of ABS, 50-70 parts of PC, 3-20 parts of IPN resin, 3-15 parts of a toughening agent, 0.1-1 part of an antioxidant and 0.2-2 parts of a lubricant. The preparation method of the energy absorption and shock absorption PC / ABS alloy comprises the following steps that (a) ABS resin, PC resin, the toughening agent, the antioxidant and the lubricant are added into a high-speed mixer for mixing; (b) the mixture obtained in the step (a) is mainly fed through a double-screw extruder, IPN components are subjected to side-feeding on a seventh zone, blending is carried out, and melting, extruding and granulating are carried out to obtain the energy absorption and shock absorption PC / ABS alloy. Compared with the prior art, the energy absorption and shock absorption PC / ABS alloy is well dispersed in the PC / ABS alloy and is mostly in a PC phase by adding a micro IPN interpenetrating network structure into the alloy through side feeding, so that the rigidity ofthe material is increased without reducing the toughness, and the energy absorption and shock absorption of the alloy are improved.

Description

technical field [0001] The invention relates to the field of polymer material processing, in particular to an energy-absorbing and shock-absorbing PC / ABS alloy and a preparation method thereof. Background technique [0002] Polycarbonate has high toughness, ABS resin can improve processing performance, PC / ABS alloy is a general-purpose alloy, but it is difficult to effectively absorb energy in some safety seats, bumpers, helmets and other scenes that require safety performance, and it is difficult to improve product safety. performance. [0003] Usually super-tough materials deform and absorb some of the energy, but do not provide protection. The high rigidity material can support the protection but cannot block the impact force. In addition, the reinforced PC / ABS alloy will be damaged when it receives external impact, and its toughness will drop sharply. [0004] Disclosed a kind of high-performance PC / ABS alloy material as CN 108219429A, its raw material formula by weig...
