PC/ABS alloy material based on waste regeneration and preparation process thereof

Abstract

The invention discloses a PC / ABS alloy material based on waste regeneration and a preparation process thereof. The alloy material is composed of the following raw materials in parts by weight: 60-80 parts of ABS water gap waste, 20-40 parts of PC water gap waste, 3-5 parts of a toughening agent, 5-8 parts of a compatilizer, 0.2-0.4 part of an antioxidant, 2-4 parts of a synergistic flame retardant, 1-3 parts of a flame retardant, 5-7 parts of black color master batch, 0.1-0.3 part of lubricating grease, and 0.5-0.7 part of an anti-dripping agent. The PC / ABS alloy material is prepared by recycling the injection molding runner water gap PC and ABS materials serving as waste materials, so that resource recycling is achieved, and environmental pollution is avoided; the internal and external stress coefficients of the material are kept uniform and stable through two-stage high-speed mixing machine processing, the material structure is blended through an antioxidant and a lubricant, the material is nitrided in the extrusion period, and nitrogen atoms permeate into chemical heat treatment of the surface layer of a workpiece; therefore, the finally prepared PC / ABS has excellent mechanical properties of wear resistance, fatigue resistance, corrosion resistance and high temperature resistance.

Description

technical field [0001] The invention relates to the technical field of waste alloy plastic preparation, in particular to a PC / ABS alloy material based on waste regeneration and a preparation process thereof. Background technique [0002] Polycarbonate (PC) is a linear polycarbonate, which is an amorphous engineering plastic with good toughness, transparency and heat resistance. ABS engineering plastic has good fluidity and impact performance. Due to their excellent properties, these materials are widely used in injection molding processing, that is, mold production and as raw materials; [0003] In the process of mold injection molding, due to the design and processing characteristics of the mold itself, especially when it involves longer or larger injection molded parts, the flow channel area of ​​the mold will also increase accordingly.

Problems solved by technology

[0003] In the process of mold injection molding, due to the design and processing characteristics of the mold itself, especially when it involves longer or larger injection molded parts, the flow channel area of ​​the mold will also increase accordingly. The quality and volume of the ABS or PC waste of the nozzle will also increase accordingly, and the runner nozzle material is generally used as the waste of mold processing, and is often discarded carelessly, which not only wastes production resources, but also causes damage to the environment. Caused unnecessary economic loss;
