Abstract

The invention discloses a heat-resistant conductive polypropylene composite material and a preparation method thereof; the heat-resistant conductive polypropylene composite material comprises components in parts by mass: 45-75 parts of polypropylene, 5-30 parts of glass fiber and 16-24 parts of conductive carbon black. The composite material takes polypropylene as matrix resin and is prepared by a one-step melt kneading method; the glass fiber and the conductive carbon black have an obvious conductive synergistic effect, so that the composite material has excellent rigidity, heat resistance and good electrical conductivity; and the surface resistance is not higher than 109W, so that the composite material can be applied to a package and a chip carrier with anti-static requirement as well as a motor vehicle and the information and communication industry with electromagnetic shielding requirement.

Description

technical field [0001] The invention relates to a polypropylene composite material, in particular to a heat-resistant and conductive polypropylene composite material and a preparation method thereof. Background technique [0002] Glass fiber reinforced polypropylene is added glass fiber and other additives to the original polypropylene matrix to improve the rigidity and heat resistance of the material and reduce shrinkage. Generally speaking, most of the glass fiber reinforced materials are mostly used in the structural parts of the product. It is a structural engineering material and expands the scope of use of polypropylene resin. [0003] Carbon black is the most commonly used conductive filler. The raw material is easy to obtain and light in weight. Its volume resistivity is about 0.1W cm. According to the filling amount, the resistivity of the composite material can be flexibly adjusted. Carbon black filled composite materials are easy to form and process, and have bee...
