Abstract
The invention discloses stable conductive rubber. The stable conductive rubber is prepared from 6-10 parts by weight of butyl rubber, 3-9 parts by weight of a sulfuration promoter, 4-8 parts by weight of a physical aging inhibitor, 2-6 parts by weight of stearic acid, 7-12 parts by weight of butadiene rubber, 3-7 parts by weight of aromatic hydrocarbon oil, 3-9 parts by weight of nanometer carbon fibers, 2-7 parts by weight of paraffin, 3-8 parts by weight of calcium sulfate, 1-4 parts by weight of nanometer zinc oxide, 2-6 parts by weight of a dispersant and 6-11 parts by weight of conductive carbon black. The stable conductive rubber has good electrical conductivity, good strength and fatigue resistance.
Description
Technical field
The present invention relates to a kind of stable conductive rubber.
Background technology
Conductive rubber typically refers to volume resistance within 9 ohmcms of 10, and because rubber is excellent isolator, volume resistance is greater than about 14 times of 10.Conductive rubber is divided into anti-electrostatic rank conductive rubber, and volume resistance, between 9 powers of 5 times to 10 of 10, is even more low to moderate one or two hundred Europe, then is that difficulty is very large lower than 50 ohmcms.The conductive rubber that graphitized carbon black is filled, volume resistance can remain on several kilo-ohms usually, and owing to employing single Shawinigan black in existing formula, its tensile strength can only reach 12Mpa, can not meet actual needs far away.Conductive rubber is military and commercially have application, and its Main Function seals and electromagnetic shielding.Product can mold pressing or extrusion molding, has on chip or other die-cut shapes is available, and shielding properties is up to 120dB(10GHz).Therefore need invention a kind ofly both to have good conductivity, there is again the rubber of larger tensile strength.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of stable conductive rubber, has good electroconductibility, have good intensity and anti-fatigue ability simultaneously.
For solving prior art problem, technical scheme provided by the invention is, a kind of stable conductive rubber, and it is made up of the raw material of following parts by weight:
Isoprene-isobutylene rubber 6-10 part, vulcanization accelerator 3-9 part, physical antioxidant 4-8 part, stearic acid 2-6 part, cis-1,4-polybutadiene rubber 7-12 part, aromatic hydrocarbon oil 3-7 part, carbon nano fiber 3-9 part, paraffin 2-7 part, calcium sulfate 3-8 part, nano zine oxide 1-4 part, dispersion agent 2-6 part, graphitized carbon black 6-11 part.
The invention has the beneficial effects as follows: stable conductive rubber of the present invention, has good electroconductibility, has good intensity and anti-fatigue ability simultaneously.
