Problems solved by technology

[0005] However, the polypropylene composites disclosed in the prior art have the disadvantage of not achieving a satisfactory combination of low temperature impact toughness and good rigidity.
Moreover, these technologies use Izod or Charpy notched impact strength to evaluate the low-temperature impact performance, and the notched impact strength can evaluate the low-temperature impact performance to some extent but cannot meet the evaluation of the safety performance of automobiles
[0006] Moreover, because the material is a poor conductor of electricity, it is easy to accumulate static charge during processing and use. When the static charge accumulates to a certain extent, static electricity will cause the material to absorb dust and cause material damage. It may also generate static spark discharge, causing chemical The product warehouse exploded and caught fire, causing major personal accidents

Abstract

The invention provides an ultra-low-temperature-resistant antistatic polypropylene composition and a preparation method thereof. The composition is prepared from the following raw materials in parts by weight: 39-90 parts of resin A, 10-40 parts of polyolefin elastomer, 1-30 parts of a filling enhancer, 1-5 parts of a low-temperature modifier, 10-15 parts of an antistatic agent and 0.1-4 parts of other auxiliary agents. The ultra-low-temperature-resistant antistatic polypropylene composition provided by the invention has good low-temperature impact toughness (particularly multi-shaft low-temperature impact strength) and good rigidity, and maintains good dimensional stability.

Description

technical field [0001] The invention belongs to the technical field of polypropylene composite materials, and in particular relates to an ultralow temperature-resistant antistatic polypropylene composition. Background technique [0002] Polypropylene is a general-purpose plastic with a wide range of uses. It is polymerized from propylene monomer. The English abbreviation is PP. Its melting point is 165-175 ° C and it is a semi-crystalline plastic. Polypropylene plastic has the characteristics of light weight and easy processing, and has become the largest and fastest-growing variety of automotive plastics. However, polypropylene material has poor low temperature resistance and low rigidity, which cannot meet the requirements and standards of automotive interior parts. Interior parts include instrument panel, auxiliary instrument panel, A, B and C pillars, glove box, door panel, rear tail box panel, etc. [0003] Automobile parts pay more and more attention to safety perfor...
