Embodiment 1

[0017] Embodiment 1: A permanent antistatic ABS flame retardant material, including styrene-acrylonitrile resin, high rubber powder, brominated flame retardant, antimony flame retardant, antistatic agent, antioxidant and lubricant, each The proportion of ingredients is:

[0018]

[0019] Wherein, the styrene-acrylonitrile resin is a SAN resin with a melt flow index greater than 2.5; the high rubber powder is butadiene, and the rubber content of the butadiene is 45%-65%. The brominated flame retardant is one of decabromodiphenylethane, tetrabromobisphenol A or bromotriazine. The antimony-based flame retardant is antimony trioxide or sodium antimonate. The antistatic agent is a polyether ester antistatic agent. The antioxidant is a compound of Ciba Irganox 1076 and Ciba Irgafos 168, and the ratio of the two is 1:2. Described lubricant is polyethylene wax or vinylbisstearamide.

Abstract

The invention discloses a permanent antistatic ABS (acrylonitrile butadiene styrene) flame-retardant material. The material is characterized by comprising, in percentage by weight, 40%-65% of styrene-acrylonitrile resin, 15%-25% of high glue powder, 8%-20% of a brominated flame retardant, 2%-6% of an antimony flame retardant, 4%-12% of an antistatic agent, 0.1%-1% of an antioxidant and 0.2%-1% of a lubricant. The styrene-acrylonitrile resin is SAN (styrene acrylonitrile) resin with the melt flow index larger than 2.5. The good anti-impact performance of the ABS is guaranteed, and the material has a permanent antistatic effect.

Description

technical field [0001] The invention relates to an ABS material, in particular to a permanent antistatic ABS flame-retardant material. Background technique [0002] ABS resin is one of the five major synthetic resins. It has excellent impact resistance, heat resistance, low temperature resistance, chemical resistance and electrical properties. It also has the characteristics of easy processing, stable product size, and good surface gloss. It is easy to paint. , coloring, and secondary processing such as surface metal spraying, electroplating, welding, hot pressing and bonding, etc. It is widely used in industrial fields such as machinery, automobiles, electronic appliances, instrumentation, textiles and construction. Wide range of thermoplastic engineering plastics. [0003] In the prior art, most of the office equipment is made of ABS material, but these materials cannot meet the long-term antistatic and flame-retardant requirements of the office equipment. Therefore, how...
