The invention provides conductive rubber, which comprises the following ingredients: 100 to 120 parts of natural gum, 40 to 50 parts of butadiene styrene rubber, 2 to 15 parts of zinc oxide, 3 to 16 parts of dicumyl peroxide, 45 to 60 parts of silver coated glass microsphere core-shell composite particles, 10 parts of carbon black N330, 5 to 16 parts of bismuth oxide, 3 to 7 parts of 4,4 minute-diisopropyl phenyl diphenylamine and 4 to 8 parts of paraffin oil. The conductive rubber provided by the invention has the following beneficial effects that 1, the conducting performance is good, and the conducting performance reduction due to reaction with other ingredients is avoided; 2, the aging cannot easily occur, and the conductive rubber cannot easily age due to external stimulation such as oxygen gas, ultraviolet rays, ozone and X rays.
Description
Technical field
The present invention relates to field of rubber materials, especially relate to a kind of conductive rubber.
Background technology
Conductive rubber is evenly distributed in silicon rubber by the conductive particle such as silver-plated, silver-colored to glass silvering, aluminium, by pressure, conductive particle contacted, reach good conductivity.Military and commercially have application.Its Main Function is sealing and electromagnetic shielding.Product can mold pressing or extrusion molding, have on chip or other die-cut shapes is available, shielding properties is up to 120dB (10GHz), but still exist in wire rubber and be subject to Magnetic stimulation and easily always change, or it is easily aging to be subject to ray image, use conventional anti-aging agent, the electroconductibility of wire rubber can be reduced.
Summary of the invention
For solving the problems of the prior art, the present invention proposes a kind of conductive rubber, comprise following component: natural gum 100-120 part, styrene-butadiene rubber(SBR) 40-50 part, zinc oxide 2-15 part, dicumyl peroxide 3-16 part, silver-colored bag glass microballon Core-shell Composite Particles 45-60 part, carbon black N330 have 10 parts, bismuth oxide 5-16 part, 4,4 '-diisopropylbenzyl pentanoic 3-7 part, paraffin oil 4-8 part.
