Problems solved by technology

Physical adsorption can have a good effect in short-term room temperature, but since adsorption and removal are a reversible process, when used at high temperature or for a long time, the physically adsorbed substances will still be emitted, endangering human health; and extraction The removal method, such as the technical solution disclosed in Chinese patent CN103740039A, can effectively reduce the emanating substances in the material, but it can only be improved during the extrusion process, and the material is degraded due to thermal oxygen after post-processing, such as injection molding. function, and will emit small molecular substances, resulting in a substantial increase in emissivity

Abstract

The invention relates to an adsorbent master batch, a low-sporadic-performance PC / ABS alloy with the same and a preparing method. The adsorbent master batch is prepared from, by weight, 10 parts to 80 parts of physical adsorbents, 20 parts to 90 parts of acrylonitrile-styrol-copolymer-grafted glycidyl methacrylate, 0.1 part to 1 part of antioxidants and 0.1 part to 1 part of lubricating agents; the low-sporadic-performance PC / ABS alloy with the adsorbent master batch is prepared from, by weight, 40 parts to 80 parts of polycarbonate, 20 parts to 60 parts of acrylonitrile-butadiene-styrene copolymers, 2 parts to 10 parts of toughening agents, 0.5 part to 10 parts of the adsorbent master batches, 0.1 part to 1 part of antioxidants and 0.1 part to 1 part of lubricating agents. Compared with the prior art, the adsorbent master batch, the low-sporadic-performance PC / ABS alloy and the preparing method have the advantage that the sporadic performance of a PC / ABS alloy material is obviously reduced.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to an adsorbent master batch, a PC / ABS alloy with low emission and a preparation method containing the master batch. Background technique [0002] PC / ABS alloy is an amorphous engineering plastic with excellent impact strength, heat resistance, high rigidity and other properties, and is widely used in automobiles, electronics, home appliances and other fields. [0003] As my country promulgated the "Guidelines for the Evaluation of Air Quality in Passenger Cars" on March 1, 2012 and began to implement it, many automobile OEMs, parts factories and even material manufacturers are very concerned about the development of materials used in low-emission automobiles and use. There are also many patents in this area. For example: CN104761877A this patent has adopted a kind of physical adsorbent to improve the emission of material; CN104592729A this patent has adopted clay and attapulgite a...
