Embodiment 1

[0015] An antistatic masterbatch for engineering plastics, its components are proportioned by mass percentage: PE 30%, polyethylene glycol alkyl ether 30%, modified calcium carbonate filler 30%, light stabilizer 5%, antioxidant 1.5% calcium stearate and 3.5% calcium stearate. The modified calcium carbonate filler is heavy calcium carbonate nanoparticles whose surface is treated with an aluminum-titanium composite coupling agent and whose particle size is 10-80nm. The light stabilizer is The compound of hindered amine high molecular weight light stabilizer GW-944Z and GW-622 with a mass ratio of 1:1, the antioxidant is hindered phenolic antioxidant 1010 and phosphite with a mass ratio of 1:1 A compound of antioxidant 168.

[0016] Preparation method: Weigh each component according to the weight ratio, and add them into the high-speed mixer respectively, and stir together for 3 to 15 minutes. After being melted and kneaded, extruded and granulated, then dried and packaged, the ...

Abstract

The invention discloses an antistatic masterbatch for engineering plastics and a preparation method thereof. The antistatic masterbatch for engineering plastics provided by the invention comprises the following components by mass: 15%-50% of a carrier, 25%-40% of an antistatic agent, 15%-50% of a modified calcium carbonate filler, 2%-8% of a light stabilizer, 0.5%-2% of an antioxidant, and 0.5%-5% of a dispersion agent. The antistatic agent is at least one of fatty acid polyethylene glycol ester, polyethylene glycol alkyl ether, polyethylene oxide, polyether ester amide, polyether ester imide, glycerol monostearate, alkyl sodium sulfonate, and nanoscale antimony doped tin oxide. When applied to engineering plastic production, the antistatic masterbatch provided by the invention has excellent antistatic properties, also maintains good mechanical properties and machinability, is low in production cost and convenient to use, and is suitable for a variety of engineering plastics.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an antistatic master batch for engineering plastics and a preparation method thereof. Background technique [0002] Plastics generally have good electrical insulation properties. In industrial production and product applications, friction and peeling often occur. This will bring electrostatic hazards to these polymer materials, such as causing distortion of precision instruments, scrapping of electronic components, fire and explosion accidents. Due to their excellent performance, engineering plastics can replace metals as structural materials, and have become new materials that cannot be replaced by any other materials in some fields. Therefore, it is widely used in automobile, machinery, electronics, electrical, chemical industry, building materials, military industry, medical treatment and sporting goods, etc. It plays an increasingly prominent role in various field...
