Abstract

The invention provides a conductive full vulcanized thermoplastic elastomer and its preparation method, and relates to the technical field of full vulcanized thermoplastic elastomer. The full vulcanized thermoplastic elastomer is obtained by melt-blending components including rubber particles having crosslinking structure with mean particle diameter of 0.02 to 1 μm, carbon nanotubes as conductive fillers and thermoplastic plastics once, wherein the weight ratio of the rubber particles and the thermoplastic plastics is from 30:70 to 75:25 and the content of conductive fillers is from 0.3 to 10 weight parts based on the total weight of rubber particles and thermoplastic plastics of 100 weight parts. The resulting conductive full vulcanized thermoplastic elastomers have low content of conductive fillers and excellent combination performances. It can be prepared by conventional rubber processing methods and can be used to produce electronic production equipment, means, electronic instrument, instrument housing and decorative materials of clean production workshop having static resistance, electro magnetic interference resistance and clean requirement.
