Problems solved by technology

Since the polypropylene material itself is a flammable and insulating material, the usual method is to add a certain amount of antistatic agent to its system to meet the antistatic performance requirements of its products, but the use of a large amount of additives will affect the mechanical properties of the polypropylene material itself. Performance such as toughness caused a significant decline

Abstract

The invention discloses a modified antistatic polypropylene material and a preparation method thereof, and the modified antistatic polypropylene material comprises the following components in parts by weight: 100-120 parts of homo-polypropylene, 20-30 parts of glass fiber, 10-20 parts of a flexibilizer, 5-10 parts of a moisture absorbent, 6-10 parts of CNT conductive master batch, 3-8 parts of an antistatic agent, 10-15 parts of graphene, 2-5 parts of a dispersant, 1-3 parts of an antioxidant, and 0.5-3 parts of a lubricant. By adding the graphene and the CNT conductive master batch, a long-acting conductive network can be formed in the polypropylene material, the polypropylene material has lasting conductivity, and by adding the moisture absorbent and the antistatic agent which can be subjected to melt polymerization with the main body material, the moisture absorption conductivity is enhanced, rapid conductivity can be achieved, and the antistatic performance of the whole material is enhanced.

Description

technical field [0001] The invention relates to the technical field of polypropylene composite materials, in particular to a modified antistatic polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a kind of thermoplastic resin prepared by polymerization of propylene monomer. Stereoregular polypropylene has good general performance, good heat resistance, stress crack resistance and rigidity, and is easy to process and shape, and the raw material price is low , has a wide range of application values, so it is widely used in various fields of production and life. [0003] Antistatic properties are widely used in various fields such as automobile interior decoration, mining, chemical industry, oil and gas transportation, etc. Since the polypropylene material itself is a flammable and insulating material, the usual method is to add a certain amount of antistatic agent to its system to meet the antistatic performance requirement...
