Abstract
The invention discloses a conductive rubber which comprises the following components in parts by weight: 30-60 parts of silicone rubber, 10-20 parts of spherical conductive particles, 10-15 parts of sulfur, 10-20 parts of zinc oxide, 5-10 parts of copper powder, 5-10 parts of conductive graphite and 1-5 parts of rosin. Compared with the prior art, the prepared conductive rubber is a dark black rubber material and is good in fluidity of a rubber compound, easy to perform vulcanization and high in qualification rate; furthermore, the conductive rubber is easy to be bonded with metal; when the conduction of electricity of the rubber from the maximum parting part achieves 500V, the electricity from the rubber to the metal is not greater than 500k omega; and the tensile strength of the rubber is not less than 21MPa, the elongation at break is not less than 550%, the anti-aging performance is good, and the conductive rubber is suitable for producing conductive liner bushings and conductive rubber vibration damping products.
Description
Technical field
The present invention relates to a kind of conductive rubber.
Background technology
Conductive rubber typically refers to volume resistance in 9 ohmcms of 10, because rubber is good isolator, volume resistance is greater than 10 about 14 times.The conductive rubber that graphitized carbon black is filled, volume resistance can remain on several kilo-ohms usually, owing to used single Shawinigan black in the existing prescription, its tensile strength can only reach 12Mpa, can not satisfy actual needs far away.
Summary of the invention
For the deficiency that prior art exists, technical problem to be solved by this invention is, a kind of with low cost, conductive rubber that conductivity is high is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of conductive rubber is grouped into by the one-tenth of following weight part:
Silicon rubber 30～60;
Spherical conductive particle 10～20;
Sulphur 10～15;
Zinc oxide 10～20;
Copper powder 5～10;
Electrically conductive graphite 5～10;
Rosin 1～5.
The advantage of conductive rubber of the present invention is: the present invention compared with prior art, made conductive rubber is the aterrimus sizing material, the rubber unvulcanizate good fluidity is easy to sulfuration processing, qualification rate is high; And be easy to and metal bonding; Rubber when the 500V, is not more than 500k Ω from maximum somatotype conduct electricity from rubber to the metal; Rubber tensile strength 〉=21Mpa, tensile yield 〉=550%, ageing-resistant performance are good, are fit to produce conduction lining and conductive rubber cushioning product.
Embodiment
Below in conjunction with specific embodiment the present invention is described in further details;
A kind of conductive rubber is grouped into by the one-tenth of following weight part:
Silicon rubber 30～60;
Spherical conductive particle 10～20;
Sulphur 10～15;
Zinc oxide 10～20;
Copper powder 5～10;
Electrically conductive graphite 5～10;
Rosin 1～5.
Certainly, above-mentioned explanation is not to be limitation of the present invention, and the present invention also is not limited to above-mentioned giving an example; those skilled in the art; in essential scope of the present invention, the variation of making, remodeling, interpolation or replacement all should belong to protection scope of the present invention.
