Embodiment Construction

[0017] The technical scheme of the present invention will be further described below in conjunction with specific examples:

[0018] A preparation method of anti-aging ABS material, comprising the following steps:

[0019] (1) Put the polycarbonate into the injection molding machine, heat it to 130°C, keep it warm for 50 minutes, add 0.1% by mass of nano-silver oxide to the obtained product, and then send it into the injection molding machine to stir for 25 minutes and then go through twin-screw extrusion Particles to obtain nano-silver oxide-polycarbonate;

[0020] (2) Mix ABS resin and nano-silver oxide-polycarbonate into the injection molding machine at a mass ratio of 75:25, mix and inject at 130°C, and then extrude and granulate through twin-screw to obtain ABS prefabricated granules;

[0021] (3) Add ABS prefabricated granules, titanium dioxide, anti-aging agent, epoxy soybean oil, organotin stabilizer, and zinc stearate into the high-mixer at a mass ratio of 85:3:0.5:2...

Abstract

The invention discloses a preparation method of an anti-aging ABS material. The preparation method comprises the following steps that (1) polycarbonate is mixed with nano silver oxide, and through twin-screw extrusion granulation, nano silver oxide-polycarbonate is obtained; (2) ABS resin and nano silver oxide-polycarbonate are mixed and conveyed into an injection molding machine for mixing injection molding, and then ABS pre-formed granules are obtained through twin-screw extrusion granulation; (3) the ABS pre-formed granules, titanium dioxide, an anti-aging agent, epoxidized soybean oil, anorganic tin stabilizer and zinc stearate are mixed and added to a high-speed mixer to be mixed and plasticized; and (4) the obtained material is cooled and conveyed into a twin-screw extrusion granulator for extrusion granulation. According to the preparation method of the anti-aging ABS material, good anti-aging and tensile properties are achieved while excellent performance of resin materials isachieved, the cost is low, the process is simple, and thus the preparation method is convenient to popularize.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of an anti-aging ABS material. Background technique [0002] ABS is a thermoplastic polymer structure material with high strength, good toughness and easy processing. ABS resin is currently the polymer with the largest output and the most widely used. It organically unifies the various properties of PS, SAN, and BS, and has excellent mechanical properties of toughness, hardness, and rigid phase balance. However, due to the development of material technology, it is often necessary to further improve some properties of materials in the actual use process in order to achieve the ideal use effect. [0003] Although the ABS material has good fluidity and a certain strength, its anti-aging and tensile strength have certain limits. For some complex or load-bearing accessories, such as electromagnetic plastic reels, they cannot fully meet the...
