Description
Technical field
The invention belongs to rubber technology field, be specifically related to a kind of cable accessory conductive silicon rubber.
Background technology
At present, conductive rubber products is very fast as the development of functional rubber goods, and range of application is increasingly extensive.
Conductive rubber belongs to conductive polymeric composite, and its electrical conduction mechanism mainly contains macroscopical seepage theory (conductive path mechanism), Bcs mechanics tunnel effect and Bcs mechanics field emission effect.Conductive path mechanism, tunnel effect and field emission effect exist in conductive rubber simultaneously, may be to take a certain or certain two kinds of mechanism as main under different condition.When conductive filler material is when critical is above, conductive path is main conduction pattern, take conductive path mechanism as main; When conductive filler material consumption is less or impressed voltage hour, the gap of isolated electron or its aggregate is compared with large and cannot participate in conduction, thermal vibration excited electron generation transition, forms larger tunnel current, now take tunnel effect as main; When amount of filler is less, between particle, internal electric field is very strong, matrix interlayer is equivalent to inner distributed capacity, and now field emission effect is more remarkable.
The conductive rubber that existing graphitized carbon black is filled, volume resistance can remain on several kilo-ohms conventionally, and because the carbon black using in existing formula is unreasonable, its tensile strength can only reach 12Mpa, can not meet actual needs far away.
