Antistatic plastic and production technology thereof

Abstract

The invention discloses antistatic plastic and a production technology thereof. The antistatic plastic is prepared from the following components in percentage by mass: 75-85% of polypropylene resin, 0.1-0.5% of a coupling agent, 2-10% of a dispersing agent, 2-6% of an antistatic agent, 0.5-1% of an antioxidant, 2-10% of inorganic filler and 5-20% of a cold-resistant agent, wherein the inorganic filler is specifically graphene, and the antistatic agent is specifically lauric diethanolamide, coconut diethanolamide, octadecyl methyl dihydroxyethyl ammonium bromide, dodecyl dimethyl phenoxy ethylammonium bromide and ethoxylated octadecylamine. The antistatic plastic prepared by using the technology has the advantages of being low-temperature-resistant, frost-resistant and capable of avoidingcracking. The plastic is resistant to low temperature of -20 to -40 DEG C and is not brittle. The preparation method has the advantages of being simple, feasible, easy to operate, suitable for industrialization and good in application prospect in the fields of refrigerators, refrigeration houses, air conditioners, cold-resistant, frost-resistant and low-temperature-resistant engines and the like.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to an antistatic plastic. Background technique [0002] Plastics have good electrical insulation and high resistivity, and are usually widely used as insulating materials. However, during the production, transportation and use of plastics, the main obstacle caused by static electricity is firstly the adsorption of dust on the plastic surface, which is very easy to pollute. Although it can be wiped off, the processed products give people a dirty feeling, thereby reducing the quality of goods. the value of. If high-potential static electricity is generated during high-speed printing and production of plastic films, the gas in the air will be ionized and spark discharge will occur, which will easily cause combustion and explosion accidents for solvents with low ignition points. Therefore, the antistatic problem of plastics has aroused people's great attention. ...

AI Technical Summary

Problems solved by technology

[0003] The plastics in the prior art have poor dimensional stability and are easy to deform; most plastics have poor low temperature resistance, become brittle at low temperatures, and are easy to age; in the production and use of refrigerators, cold storage, air conditioners, and cold-resistant and low-temperature resistant engines, etc., low-temperature and cold-resistant It needs to have both properties and antistatic properties at the same time, so there is an urgent need for a cold-resistant and antistatic plastic in the market
