Abstract

The invention provides a conductive thermoplastic elastomer and a preparation method thereof. The thermoplastic elastomer includes following blended components: a. thermoplastic resin; b. rubber particles having crosslinking structures; c. a conductive filling material; and d. low-melting-point metal. Gel content in the component b is, by weight, 60% or more than 60%. An average particle size of the rubber particles is 0.02-1 [mu]m. The component c is not melted at a processing temperature of the thermoplastic resin. The component d is at least one of a single-component metal and a metal alloy. A melting point of the component d ranges from 20-480 DEG C and is lower than the processing temperature of the thermoplastic resin. A weight ratio of the component b to the component a is more than 30:70 and is lower than 75:25. The conductive polymer composite material is low in filling amount of the conductive filling material and the low-melting-point metal, is excellent in conductive performance, can be prepared through a melt blending method, can be used for manufacturing electronic production devices and tools which have an anti-static function and an electromagnetic wave interference resistant function and is of a dust-free requirement, can be used for manufacturing shells of electronic instruments and meters, can be used as a decoration material in a dust-free production workshop and can be used as shells and circuit boards of various flexible electronic products.

Description

technical field

[0001] The present invention relates to a fully vulcanized thermoplastic elastomer, and furthermore, the present invention relates to a conductive fully vulcanized thermoplastic elastomer and a preparation method thereof. Background technique

[0002] Fully vulcanized thermoplastic elastomer is a new material developed in the 1980s. It has the characteristics of both plastic and rubber: it shows high elasticity of rubber at room temperature, and can be plasticized at high temperature. The strength, elasticity, heat resistance and compression set resistance of fully vulcanized thermoplastic elastomers are greatly improved compared with uncrosslinked thermoplastic elastomers. At the same time, the chemical resistance and processing stability are significantly improved, and the rubber-plastic blending ratio can be changed in a wide range, so that the material has greater room for adjustment in performance. Therefore, the application range is very wide. In the...
