Abstract
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...
Examples
Embodiment 1
[0048] Weigh the following materials in proportion:
[0049] PC / ABS scrap 81
[0050] SMA resin 3
[0051] MBS 3
[0052] Brominated polycarbonate (58% bromine content) 6
[0054] Acrylic impact modifier 5.5
[0055] Antioxidant 1010 0.3
[0056] UV absorber 0.2
[0057] Then the blended material is mixed and granulated in an extruder, and the resulting mixed and granulated product is made into a finished product by injection molding. Finally, the mechanical properties of the finished product are tested according to the national standard GB13525 / T-92 and the UL94 standard of the American Electrotechnical Association. Test its flame retardant performance, and measure the melt mass flow rate (MFR) of the product according to the national standard GB / T3682-2000. The results are compared with the performance of PC / ABS raw materials before improvement, as shown in Table 1.
