Problems solved by technology

[0004] However, small molecule antistatic agents and metal salt antistatic agents migrate to the surface of polypropylene materials to absorb water to play an antistatic effect, but these antistatic agents are greatly affected by the environment and are easy to fall off, making the antistatic effect disappear.
Although the black conductive inorganic material can obtain permanent antistatic, but its high addition amount will affect the mechanical properties and color range of the material

Abstract

The invention discloses an antistatic polypropylene composition. The antistatic polypropylene composition is prepared from the following components in parts by weight: 40 to 80 parts of polypropyleneresin and 1 to 8 parts of antistatic agent, wherein the antistatic agent is hyperbranched polyethylenimine. According to the antistatic polypropylene composition disclosed by the invention, the hyperbranched polyethylenimine is added and is used as the antistatic agent; the tail end of the hyperbranched polyethylenimine contains a lot of amino groups; the amino groups absorb water in the air to become conductive, so that the surface resistivity is reduced, static electricity is eliminated and the composition has the antistatic effect; the antistatic polypropylene composition disclosed by the invention has excellent long-period antistatic property and mechanical property; the antistatic polypropylene composition can be used for preparing inner and outer ornaments of automobiles, improving the antistatic property, reducing the dust collection degree and keeping parts clean and beautiful.

Description

technical field [0001] The invention relates to a polypropylene composition, in particular to an antistatic polypropylene composition. Background technique [0002] Polypropylene (PP) is a semi-crystalline polymer with excellent mechanical properties, heat resistance, chemical resistance and easy formability, and is widely used in industries such as automobiles, home appliances and construction. Polypropylene has strong electrical insulation due to its small molecular polarity and poor water absorption (surface resistivity is as high as 10 16 Ω·m), in the process of production and use, due to friction, peeling or induction process, the plastic surface will generate and accumulate static electricity, resulting in static electricity hazards, such as dust absorption, discharge, breakdown, and even combustion or explosion. Static electricity will also prevent all the materials in the packaging bag from being poured out, and will be adsorbed on the inner wall of the packaging ba...
