High-performance PC (Polycarbonate)/ABS (Acrylonitrile Butadiene Styrene) alloy prepared by waste electrical PC/ABS material and preparation method and application thereof

Abstract

The invention discloses a high-performance PC (Polycarbonate) / ABS (Polyacrylonitrile) alloy prepared by waste electrical PC / ABS material and a preparation method and an application of high-performance PC (Polycarbonate) / ABS (Polyacrylonitrile) alloy. The PC / ABS alloy comprises the following material components by weight: 95-97 parts of waste electrical PC / ABS crushed materials, 0.2-0.4 part of B-215 long-acting heat stabilizer, 2-4 parts of SBS (sodiumbisulfite) flexibilizer, 1-2 parts of EMA flexibilizer and 0.3-0.5 part of anti-ultraviolet agent. The PC / ABS alloy provided by the invention has the characteristics of high performance, high flame retardance, high impact resistance, high coldness resistance, high stability and static electricity resistance and the like, can be used for manufacturing an intelligent electric meter housing, a meter housing, a fax machine housing or a copier housing and the like.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to waste plastic recycling technology, in particular to a technology for preparing high-performance PC / ABS alloys from waste electrical PC / ABS materials. Background technique [0002] Polycarbonate (PC) is a general-purpose plastic that contains carbonate groups. According to the structure of ester groups, it can be divided into aliphatic, aromatic and other types. It is a colorless and transparent amorphous thermoplastic material. The chemical properties are weak acid resistance, weak alkali resistance, neutral oil resistance, ultraviolet light resistance and strong alkali resistance, and its physical property is linear expansion rate: 38×10cm / cm 2 , The thermal deformation temperature is 135°C, and it has the disadvantages of poor stability, easy cracking due to stress, low impact resistance to notches, poor wear resistance, low adhesion to metal parts, high viscosity, p...

Problems solved by technology

[0005] (1) Incineration or landfill, since harmful gases such as sulfur dioxide are produced during the incineration process, it is easy to cause environmental pollution, and landfill will waste Land resources, the refractory nature of polycarbonate / ABS will also cause great harm to the environment, and this method is currently being phased out;

[0006] (2) Simply recycle and granulate such waste electrical housing materials, defective materials, defective products or recycled products without any scientific modification, and downgrade them to ordinary plastics. Although the problem of environmental pollution has been solved, it has not Making full use of the economic value of these secondary materials will cause the root cause of inferior products in the market
