Abstract
The invention discloses conductive rubber and relates to the field of rubber. According to the produced conductive rubber, the heat resistance, the air tightness and the deformation resistance are good, the production is simple, the energy-saving and environment-friendly effect is achieved, the shielding effect is good, the tensile strength is large, the anti-aging capability is high, and the conductive rubber is suitable for production and machining requirements.
Description
Technical field
The present invention relates to rubber materials, be specifically related to a kind of conductive rubber.
Background technology
Along with the high speed development of modern science and technology, the widespread use of each class of electronic devices, the healthy impact of its hertzian wave on electronics and people highlights, therefore electromagnetic wave shielding device more extensively should in various electronic, stability and the tolerance range of its electromagnetic wave shielding are also more and more higher, this needs the electromagnetic shielding material providing softness good, as conductive rubber.
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.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.
Summary of the invention
In order to realize object of the present invention, technical scheme provided by the invention: a kind of conductive rubber, comprise natural rubber, nano zine oxide, coumarone indene resin, silicon-dioxide, electro-conductive material and catalyzer, the formula of described conductive rubber, by weight, natural rubber 40-60 part, nano zine oxide 10-15 part, coumarone indene resin 2-7 part, silica 1 0-15 part, electro-conductive material 6-10 part and catalyzer 3-6 part.
Preferably, by weight, natural rubber 50 parts, nano zine oxide 10 parts, coumarone indene resin 5 parts, silica 11 part, electro-conductive material 6 parts and catalyzer 4 parts.
Preferably, described electro-conductive material is glass silvering particle and the silver-plated particle of the aluminium ratio composite grain according to 1:1.
The present invention compared with prior art, adopts conductive rubber prepared by above-mentioned formula, and thermotolerance, resistance to air loss and non-deformability are good, and preparation is simple, energy-conserving and environment-protective, have good shield effectiveness, larger tensile strength, and there is very strong durability, be applicable to the needs of process for processing.
