Abstract

A formula of PC/ABS waste materials recycle essentially comprises the ingredient components in mass fraction ratio: 80 to 90 PC/ABS waste materials, 1 to 3 for compatilizer, 1 to 3 plasticizer, 3 to 8 for bromide fire retardant, 1 to 3 for stibium fire retardant, 4 to 8 for acrylic acid impact resistance modifier, 0.2 to 0.5 oxidation inhibitor, 0.1 to 0.3 for ultraviolet absorber. By adding auxiliary agent such as compatilizer, plasticizer, fire retardant and antiaging dope, etc., the formula of PC/ABS waste materials recycle of the invention reproduces and reuses the PC/ABS waste materials based on environmental protective, and achieves the PC/ABS raw material standard of various properties of PC/ABS waste materials; so that the invention reduces the production cost, avoids the environmental pollution and has favorable social benefits and economic benefits.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a recycling formula of polymer materials. Background technique [0002] PC / ABS resin 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 and...
