Abstract

The invention provides an energy-absorbing and shock-absorbing PC / ABS alloy and a preparation method thereof. The alloy comprises the following components in parts by weight: ABS: 30-50, PC: 50-70; IPN resin 3-20, Toughener 3-15, antioxidant 0.1-1, lubricant 0.2-2. The preparation method of the alloy comprises the following steps: (a) adding ABS resin, PC resin, toughening agent, antioxidant and lubricant into a high-speed mixer for mixing; (b) passing the mixture obtained in step (a) through a twin-screw The extruder is mainly fed, and the IPN component is fed in the seventh zone, blended, melted and extruded, and granulated. Compared with the prior art, the energy-absorbing alloy provided by the present invention adds a microscopic IPN interpenetrating network structure into the alloy through side feeding, and is well dispersed in the PC / ABS alloy and most of it is in the PC phase, increasing the material Rigidity does not reduce toughness at the same time, improving the energy absorption and shock absorption of the alloy.

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...
