Problems solved by technology

The antistatic agents currently used have their good antistatic side, but they also have great limitations. They either have poor timeliness for use, or have problems with stickiness and odor, or affect other physical properties, or are restricted by color. Either the cost is high, it is difficult to produce industrially, or it is limited by compatibility, and many are affected by air humidity, so a kind of static electricity can be developed that can not only reduce the generation of static electricity, but also eliminate the generated static electricity, and can overcome the above problems. The additive is the ideal antistatic agent

Abstract

The invention discloses an antistatic PC / ABS (Poly Carbonate / Acrylonitrile Butadiene Styrene) alloy material which comprises 70 to 80 parts of PC, 5 to 10 parts of ABS, 0.5 to 1.0 part of a solubilizer, 3 to 5 parts of a flexibilizer, 8 to 12 parts of a compound antistatic agent, 0.5 to 1.0 part of a heat stabilizer DSTP (disteaxyl thiodipropionate), 0.1 to 0.5 part of an antioxidant 1010, and 0.1-0.5 part of an antioxidant 168, wherein the compound antistatic agent is formed by compounding ABS and siloxane. According to the invention, the PC / ABS alloy material is used as a base material; by compounding the ABS and the siloxane, the static elimination is carried out, so that the antistatic performance of the material is ensured and meanwhile, the impact resistance, the mechanical property and transparency of the material are all well reinforced; the solubilizer promotes compatibility between the compound antioxidant and the alloy material; the flexibilizer enhances the toughness of the material.

Description

technical field [0001] The invention relates to a PC / ABS alloy material, in particular to an antistatic PC / ABS alloy material and a preparation method thereof, belonging to the technical field of chemical materials. Background technique [0002] At present, PC / ABS alloy is the most widely used and sold variety among PC alloys. It is used in many fields, such as automobiles, machinery, electronics, chemicals, building materials, medical treatment and sports, etc., and occupies an important position in the national economy. . The alloy materials in the above fields need to have high impact resistance and certain antistatic properties. [0003] Polymer materials are prone to static electricity accumulation during use, leading to dust collection, electric shock, and even spark discharge and other undesirable phenomena, so their use in some fields is limited. In order to solve the above problems, it is common practice to add an antistatic agent to the polymer material to reduce...
