Abstract

The invention relates to a conductive thermoplastic resin composition as well as a preparation method and application thereof. The composition comprises the following components in parts by weight: 40-90 parts of polypropylene; 0.05 to 2 parts of a carbon nano tube; 10 to 30 parts of conductive carbon black; 2 to 20 parts of a cycloolefin copolymer; and 0.5 to 2 parts of an ethyoxyl amide compound. The composition is high in resistance retention rate, high in tensile strength and small in carbon black shedding amount after being subjected to stretching processing.

Description

technical field [0001] The invention belongs to the field of conductive plastics, in particular to a conductive thermoplastic resin composition and its preparation method and application. Background technique [0002] Conductive plastics have the advantages of ordinary plastics (light weight, low price, corrosion resistance, easy molding, etc.), and have metal-like conductive properties, so they are widely used in electronics, chemical and energy fields. Conductive plastics need to go through different processing steps to make products of different shapes according to application requirements, such as injection molding, spinning, extrusion and stretching. Among them, during the stretching (especially high stretching ratio) process of the conductive carbon black filled conductive material, due to the internal microstructure changes under the tensile load, the resistivity after stretching is greatly increased compared with that before stretching, and There is the problem of c...
