Problems solved by technology

The mechanism of action of the small molecule antistatic agent is that, due to its poor compatibility with the polymer, it will migrate to the surface of the product after a period of time to form an oriented amphiphilic molecular layer, and the outward hydrophilic group can absorb water. Form a conductive layer to eliminate static electricity. This type of antistatic agent has a certain degree of persistence, but as the surface conductive layer continues to wear, it will still be exhausted after a period of time

Abstract

The invention provides a permanent antistatic high-toughness talcum powder filled polypropylene material and a preparation method thereof. The polypropylene material is prepared from the following components by weight: 40 to 80 parts of polypropylene resin, 5 to 20 parts of antistatic functional master batch, 2 to 10 parts of polyethylene, 5 to 20 parts of ethylene-octene copolymer (POE), 5 to 30parts of talcum powder, 0.2 to 2 parts of stabilizer and 0.5 to 2 parts of toner. The invention relates to a permanent antistatic high-toughness talcum powder filled polypropylene material and a preparation method thereof. By adding the antistatic functional master batch taking the polypropylene resin as the matrix and selecting the POE-polyethylene synergistic toughening system, the material hasa permanent antistatic effect and excellent mechanical properties, especially higher notch impact strength.

Description

technical field [0001] The invention belongs to the field of modified plastics, and in particular relates to a permanent antistatic high toughness talcum powder filled polypropylene material and a preparation method thereof. Background technique [0002] Polypropylene is a polymer with excellent performance. It is widely used in industries such as automobiles and home appliances because of its advantages such as light weight, non-toxicity, easy molding and processing, and chemical corrosion resistance. Since the molecular chain of polypropylene is polar and has poor water absorption, it has strong electrical insulation, and it is easy to generate and accumulate static electricity during actual use. When the static electricity on the surface of the material accumulates too much, it will cause dust collection, dust accumulation, discharge and other hazards, which will affect the processing and use of the material, and may even cause explosions and other accidents in severe cas...
