Antistatic anti-aging plastic and preparation method thereof

Abstract

The invention discloses an antistatic anti-aging plastic and a preparation method thereof. The antistatic anti-aging plastic is mainly prepared from the following raw materials in parts by weight: 110-130 parts of HDPE (high-density polyethylene), 40-55 parts of PVC (polyvinyl chloride), 30-40 parts of PA6 (polyamide 6), 10-15 parts of coupling agent, 10-12 parts of hydroxymethyl fatty amine, 10-20 parts of shock-resistant modifier, 14-18 parts of polyalcohol, 5-10 parts of antistatic agent, 10-20 parts of carbon black, 5-10 parts of antioxidant, 10-20 parts of DOP (dioctyl phthalate), 10-15 parts of ultraviolet absorbent, 5-10 parts of epoxy octyl stearate and 1-5 parts of barium stearate. 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 and aging resistance.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to an antistatic and antiaging plastic and a preparation method thereof. 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...

Problems solved by technology

[0003] At the same time, plastics cannot only have antistatic properties to meet people's requirements for plastic properties; they also have other properties. Cracks occur, reducing the service life, and some plastics with better effects are made through complicated processes, but the product cost is too high

Most of the modified plastics on the market are monosexually modified, and there are no plastics with anti-aging and flame retardancy. For example, Chinese patent 201010273202 discloses aging-resistant and environmentally friendly plastics. Anti-aging, but the bending strength and hardness are not high enough to meet the requirements of the existing market for materials
