Problems solved by technology

Since PC / ABS alloys are widely used in electronic and electrical products, the amount of waste materials produced after such products are scrapped is very large. In order to reduce environmental pressure and energy consumption, and improve resource utilization efficiency, the traditional method of incinerating and burying waste materials The method is not economical and practical enough, so it is very critical to develop the regeneration of waste materials; in the production process of high-impact PC / ABS alloy, some nozzle materials will be produced due to the reason of the injection molding machine runner and the poor molding of the product. If these nozzle materials are not If it is used, it is quite wasteful and leads to environmental pollution

Abstract

The components containing in a recycle formula of PC / ABS alloy waste can be expressed in terms of mass fraction as 40 to 50 for PC / ABS waste, high-impact PC / ABS, 35 to 55 for regrinds, 1 to 3 for plasticizers, 3 to 7 for bromide fire retardant, 1 to 3 for stibium fire retardant, 2 to 7 for acrylic impact modifiers, and 0.2 to 0.5 for oxidation inhibitor. By mixing high-impact PC / ABS regrinds with general PC / ABS waste and adding various assistant, the formula of the invention can ensure that different properties of PC / ABS alloy waste meets the PC / ABS raw material standard, thereby, with quite good social and economic benefits, the formula can not only reduce production cost but also avoid the environmental pollution caused by the waste.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a formula for recovering polymer materials. Background technique [0002] PC / ABS alloy is a kind of engineering plastic with good comprehensive performance developed in the mid-1960s. It not only has the heat resistance, mechanical strength and dimensional stability of PC, but also has the advantages of easy processability and low price of ABS resin. ; It has good comprehensive performance and reasonable cost performance, and can be widely used in the fields of automobile industry and household appliances. Since PC / ABS alloys are widely used in electronic and electrical products, the amount of waste materials produced after such products are scrapped is very large. In order to reduce environmental pressure and energy consumption and improve resource utilization efficiency, the traditional method of incinerating and burying waste materials The method is not economical a...
