Abstract
A kind of composite material of high conductivity is grouped as by each group of the quality for following percentage：1~3% polypropylene, 1~3% polyethylene, 0.1~0.5% maleic anhydride, 0.1~0.5% polar monomer, 2~4% plasticizer, remaining is carbon black.The invention has the beneficial effects that：This alloy can be with the performance that resistance is low, conductivity is high, and for resistivity less than 0.3 Ω .cm, formula design is simple, and conductive filler is easily dispersed, and fluid viscosity is relatively low, can be prepared completely by simple plastics molding process such as extruding or injection molding.
Description
First, technical field
The present invention relates to a kind of composite material, more particularly to a kind of composite material of high conductivity.
2nd, background technology
With the development of defense and commercial industry, higher requirement is proposed to the comprehensive performance of conductive material.Conduction material
The electric property of material is more and more valued by people as one of index for reflecting its comprehensive performance.Especially as conduction
The resistivity of one of material electric property index, not only reflects the conductive capability of material, and with the ingredient of material and interior
Portion organizes related, and the interior tissue of material is related with its condition of heat treatment.So the resistivity of material is heat-treated shape with it
State and mechanical property necessarily have certain association (because the mechanical property of material is also dependent upon the ingredient and interior tissue of material).
The collocation use of the dispersed and rational conductive filler type of conductive filler is to prepare the highly conductive composite wood of production
The key of material.To improve conductive filler dispersibility, enhancing the mechanical performance of composite material and improving processing forming, Ren Menyi
As coupling agent or lubricant etc. are added in compound system, but the addition of a small amount of coupling agent and lubricant can not often realize improvement
The purpose of conductive filler dispersibility and enhancing interface cohesion, and largely add in the decline for easily leading to electric conductivity.Also someone's profit
Appropriate processing early period is carried out to conductive filler with coupling agent etc., but which increase the complexity of entire technological process.
Study at this stage it is a kind of there is resistance is low, conductivity is high performance, it is energy saving and can be used in multiple fields
Conductive material is very important.
3rd, invention content
