Problems solved by technology

Such as carbon black, carbon fiber, carbon nanotubes, etc., carbon black and carbon fiber are generally added in a large amount, resulting in poor toughness of the material
[0004] Chinese patent CN 110615953A discloses an antistatic ABS composite material and its preparation method. The invention introduces ionic liquid as a compatibilizer for ABS resin and carbon nanotubes. By adding 2-5 parts of carbon nanotube antistatic agents, the material The surface resistance of the 10 5 Ω, but the amount of carbon nanotubes added is more, the impact of the material is reduced
[0005] Chinese patent CN102268171A discloses a new type of antistatic resin material and its preparation method. Through the synergistic effect of carbon black, carbon nanotubes and polyaniline, the surface resistance of the material reaches 10 5 Ω is even lower, but there are many types of antistatic agents, and the overall addition amount is relatively high, resulting in a large loss of mechanical properties of the material

Abstract

The invention discloses a carbon nanotube modified permanent antistatic ABS material and a preparation method thereof, and belongs to the field of high polymer materials. The carbon nanotube modifiedpermanent antistatic ABS material comprises the following components in percentage by mass: 95%-98% of ABS resin, 1%-3% of carbon nanotube masterbatch, 0.5%-2% of a compatilizer, 0.2%-1% of an antioxidant and 0.2%-1% of a lubricant. The invention also discloses a preparation method. According to the method, the carbon nanotube masterbatch is prepared from the low-polarity resin, then the ABS resinand the carbon nanotube masterbatch are blended and extruded, the carbon nano tube exists in a low-polarity component, the structure of the carbon nano tube is kept complete, and the antistatic effect can be achieved when the actual adding amount of the carbon nano tube is reduced to be within 1%; meanwhile, the mechanical property and the processability of the material are good.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a permanent antistatic ABS material modified by carbon nanotubes and a preparation method thereof. Background technique [0002] ABS resin is a polymer material with high impact, high rigidity, low temperature resistance and easy processing and molding. It also has good gloss and chemical resistance. It is widely used in household appliances, electronic appliances, automobiles and other industries. However, ABS resin is an insulating material, and it is easy to accumulate static electricity during use and cause danger, thus limiting the application of ABS resin. [0003] At present, the antistatic modification methods of ABS resin mainly include the following methods: 1. Adding surfactants or conductive polymers. Surfactants generally only produce short-term antistatic effects; while conductive polymers are generally added in large amounts, which have a gre...
