The novel conductive rubber is high in conductivity and good in shielding effect and capable of meeting the high conductivity requirement as various high-conductivity materials are used. The novel conductive rubber is reasonable in ingredients, low in production cost, oil-proof and high-temperature-resistant, and raw materials are easily obtained.
Description
Technical field
The present invention relates to the rubber technology field, be specifically related to a kind of novel conductive rubber.
Background technology
High speed development along with modern science and technology, the widespread use of each class of electronic devices, its hertzian wave highlights electronics and people's healthy impact, therefore electromagnetic wave shielding device more extensively should be in various electronic, stability and the tolerance range of its electromagnetic wave shielding are also more and more higher, this need to provide the electromagnetic shielding material that flexibility is good, as conductive rubber.Conductive rubber is that the conductive particles such as glass silvering, aluminium be silver-plated, silver-colored are distributed in silicon rubber, by pressure, makes the conductive particle contact, reaches good conductivity, can be for military and commercial use.But the conductive rubber material resistivity had on the market at present is higher, affected the effect of electromagnetic shielding.
Summary of the invention
For the deficiencies in the prior art, technical problem to be solved by this invention is, provides a kind of resistivity little, and electric conductivity is high, and shield effectiveness is good, can effectively meet the novel conductive rubber of the requirement of high conductivity.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of novel conductive rubber, raw material by following parts by weight is made: silicon rubber 40-60 part, stearic acid 10-20 part, white carbon black 5-15 part, vinyl polysiloxane 15-25 part, whipping agent 5-10 part, catalyzer 5-8 part, electrically conductive graphite 2-8 part, copper powder 10-15 part.
The advantage of novel conductive rubber of the present invention is: the present invention uses multiple high conductivity material to make its electric conductivity high, and shield effectiveness is good, can effectively meet the requirement of high conductivity.Composition is reasonable, and starting material are easy to get, and production cost is low, and oil resistant is high temperature resistant.
