A raw materials formula of the polycarbonate / ABS alloy comprises the following components by weight parts: 25-50 parts of PC, 20-50 parts of PC reworked material, 20-30 parts of ABS reworked material, 5-10 parts of MBS, 5-8 parts of TPP, 0.3-0.5 part of FR2025 fire retardant, 0.5-2 parts of titanium dioxide, 0.1-0.5 part of anti-oxidant1010, 0.1-0.5 part of anti-oxidant168, 0.1-0.5 part of ultraviolet resistance agentUV-531, 0.03-0.08 part of proliferation powderEBS, 0.02-0.06 part of ultramarine powder, 0.02-0.4 part of iron oxide red powder and 0.005-0.01 part of high temperature resistance fluorescent yellow powder. The alloy of the invention has the characteristics of high performance, high flame retardation, high impact, high stability, antistatic property and the like, and can be used for producing intelligent ammeter housing and terminal strips.

Description

technical field [0001] The present invention relates to the field of polymer materials, in particular to the field of polycarbonate / ABS alloys, in particular to a polycarbonate / ABS alloy prepared by using recycled polycarbonate materials and ABS recycled materials, a preparation method thereof and a method for preparing a smart meter Applications in housings, terminal blocks. 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 crac...

Problems solved by technology

[0006] (1) Incineration or landfill method, because harmful gases such as sulfur dioxide are generated during the incineration process, which can easily cause environmental pollution, and landfill method, polycarbonate The refractory properties of ester and ABS will also cause great harm to the environment, and this method is currently being phased out;

[0007] (2) Simple recovery and granulation of defective materials, defective products or recycled products without any modification, downgraded to ordinary plastics, although it solves the problem of environmental Pollution problems, but failed to fully utilize the economic value of these waste materials
