A kind of antistatic plastic and preparation method thereof

Abstract

The invention discloses an antistatic plastic and a preparation method thereof. The antistatic plastic is mainly prepared from the following raw materials in parts by mass: 110-130 parts of PVC (polyvinyl chloride), 30-35 parts of PP (polypropylene), 30-40 parts of ABS (acrylonitrile-butadiene-styrene), 10-15 parts of fatty group sulfonate, 5-8 parts of tribasic lead sulfate, 4-8 parts of catalyst, 5-10 parts of antistatic agent, 10-20 parts of carbon black, 6-10 parts of hydroxymethyl fatty amine, 10-20 parts of shock-resistant modifier, 10-15 parts of graphite, 3-6 parts of cocatalyst, 5-10 parts of dibasic lead phosphite and 1-5 parts of white oil. The preparation method comprises the following steps: thoroughly mixing the components uniformly; adding the mixture into a double screw extruder; granulating by melting and plastification under certain conditions; and carrying out injection molding on the granules under certain conditions. The method disclosed by the invention is simple in technique, and convenient for large-scale production; and the product has the advantages of high notch impact strength, high bending strength, high hardness, and favorable antistatic property.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antistatic plastic. technical background [0002] Plastic material is a material with good performance. Because plastic has the advantages of light weight, no rust, and good insulation, it is used in many aspects of electronic product production. Plastic is easy to process, has good dimensional stability and surface gloss, and is easy to paint. Coloring, widely used in the field of electronic appliances. In recent years, in the electronic and electrical market, plastics have to maintain their position in the electronic and electrical market, and their performance must be improved. For example, the generation of static electricity will bring many troubles, such as electrostatic discharge, which will harm electronic equipment, cause various failures of equipment, and shorten the service life. With the expansion of the market for electronic and electrical products,...

AI Technical Summary

Problems solved by technology

However, general-purpose plastics on the market have low thermal conductivity, low operating temperature, high hardness of fillers, great wear and tear on equipment, and are prone to static electricity.

[0003] The quality of the existing antistatic plastics on the market is not stable, its bending strength and hardness are not high, and its service life is short, which cannot meet the requirements of the existing market for materials; and some plastics with better effects have undergone complicated processes. Made, but the product cost is too high

For example, Chinese patent 201210311205.2 discloses a formula for antistatic plastics and a formula for antistatic modified plastics disclosed in 201210261587.2. The antistatic plastics disclosed in these two patents have low bending strength and hardness and short service life.
