Description
Technical Field
The invention relates to the technical field of ABS (Acrylonitrile butadiene styrene) base materials and preparation, in particular to an antistatic ABS base material and a preparation method thereof.
Background
ABS is a terpolymer composed of acrylonitrile, butadiene and styrene, is one of the most widely used engineering plastics, has excellent performances of high strength, insulation, corrosion resistance and the like, and is widely applied to industries of chemical industry, coal, building decoration, radio communication and the like. However, ABS is susceptible to static electricity, which causes accidents such as fire explosion and failure of electronic components in chemical plants, oil houses, coal mines, etc., and thus, antistatic modification of ABS is required. The common antistatic modification modes are two, one is to reduce the friction coefficient of the ABS surface and reduce the generation of charges; another is to add a conductive medium to the ABS to rapidly transfer charge. The latter method has obvious advantages in terms of antistatic mechanism, and can completely eliminate electrostatic hazard. The ABS antistatic material is a hard sheet material which is prepared by mixing ABS resin as a main body, conducting fillers and carrying out mixing and plasticizing processing, is a permanent static conductor and is homogeneous and transparent, namely the materials from bottom to surface are the same, and when the appearance of the material is burnt or scratched, the damaged surface is polished by a polisher and then waxed again as new.
Antistatic materials have a strict demarcation in terms of resistance. The common resistance value is 10 6 ～10 9 The material between omega is called antistatic material, and the resistance value is 10 4 ～10 6 Between Ω is called conductive material. The antistatic material is mainly used for spaces with special requirements on static electricity, such as machine rooms, special wards, fine workshops and the like. Graphite is a natural mineral resource, graphene can be prepared from the graphite, and the conductivity of the graphene is hundreds of times higher than that of common nonmetallic ores, so that the graphene is an ideal antistatic modified material. However, for applications requiring antistatic properties, graphene contents of more than 5% are required. However, the bulk density of graphite or graphene is extremely small, more than 1% of the bulk density is difficult to disperse uniformly, the bulk density is far greater than the bearing capacity of ABS, the mechanical properties of the composite material are drastically reduced due to the high addition amount of the graphite or graphene, meanwhile, the material also loses the characteristics of light plastic, and the density of the material is drastically increased. Wang Pinghua et al found by modified graphene doped ABS studies that when the modified graphene content was 1.8%, the volume resistance was 6.46×10 8 Omega, the impact strength of the material gradually decreases with the increase of the graphene content (Wang Pinghua, wang Zhigang, liu Chunhua, etc.. Research on the influence of graphene composite material on ABS performance [ J ]]Chemical new material 2011,39 (9): 3.).
