Abstract

The invention discloses conductive rubber, which contains the following substances: natural rubber, zinc oxide, stearic acid, anti-aging agent, Rhine powder 25, middle and ultrahigh wear-resistance carbon black N220, acetylene carbon black, 46# machine oil, scorch retarder, polymeric sulphur, diethyldithiocarbamicacid, 4-4'-dithiodimorpholine and N-hexamethylene-2-benzothiazole sulfonamide. Compared with the prior art, the produced conductive rubber is an atrous rubber material, is excellent in gross rubber fluidity, is easy to be vulcanized and processed and is high in yield; the conductive rubber can be easily caked with metal; when 500V electricity is conducted by the rubber in a maximum parting position, resistance is not more than 500 kilo-ohms from the rubber to the metal; a tensile strength of the rubber is more than or equal to 21Mpa; an elongation at break is more than or equal to 550 percent; and the rubber is excellent in ageing resistance and is suitable for the production of a conductive bush and a conductive rubber damping product.

Description

Conductive rubber
Technical field
The present invention relates to rubber, particularly relate to the conductive rubber that is used for lining.
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
Technical problem to be solved by this invention provides a kind of tensile strength can be greater than the conductive rubber of 21Mpa.
The technical scheme of technical solution problem of the present invention is: conductive rubber, contain following material and weight part:
Figure BDA0000086509590000011
Figure BDA0000086509590000021
Preferred conductive rubber, contain following material and weight part:
Figure BDA0000086509590000022
The model of described anti-aging agent is BLE.
The model of described scorch retarder is CTP-80.
Preparing method of the present invention is identical with the preparation method of existing conductive rubber.
Among the present invention, the consumption of the wear-resisting carbon black N220 of middle superelevation is too much or very few, all can not accomplish the present invention.
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 property; 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.
