Abstract

The invention provides a PC / ABS alloy material with low odor and low emission, and a preparation method and application thereof. The PC / ABS alloy material, based on the total weight of polycarbonate resin, ABS resin, compatibilizer and foamed polymer as 100%, includes the following raw material components: polycarbonate resin 30-90%, ABS resin 5% ‑60%, compatibilizer 0.5‑10%, foamed polymer 0.1‑10%. The PC / ABS alloy material of the invention not only has the characteristics of low odor and low emission, but also has excellent mechanical properties and good hydrolysis resistance.

Description

technical field [0001] The invention belongs to the field of polymers, and in particular relates to a PC / ABS alloy material with low odor and low emission, and a preparation method and application thereof. Background technique [0002] PC / ABS alloy material is one of the common materials for automotive interior parts, such as instrument panel frame, sub-instrument panel, ceiling controller, air-conditioning outlet, defogging grille, interior rearview mirror, etc. [0003] As the safety of air quality inside the car is getting more and more attention, it is imperative to research and develop PC / ABS alloy materials with low VOC (volatile organic compounds) content and low odor. [0004] A lot of research work has been done on how to reduce the odor and VOC content of PC / ABS alloy materials. For example: Patent document CN101469122A discloses: a PC / ABS alloy material with low odor and low emission: PC resin 50-80%, ABS / PP graft 10-45%, hydrophobic odor-absorbing masterbatch 1-...
