Description
Technical field
The invention belongs to chemical material field, relate to a kind of energy conductive rubber.
Background technology
Conductive rubber is that conductive particle is evenly distributed in silicon rubber by glass silvering, aluminium be silver-plated, silver-colored etc., by pressure, conductive particle is contacted, and reaches good conductivity.Military and commercially have an application.Its Main Function is sealing and electromagnetic shielding.Product can mold pressing or extrusion molding, has on chip or other die-cut shapes is available.Shielding properties is up to 120dB(10GHz).Being divided into graphite nickel plating fills out silicon rubber, silver-colored filled silicon rubber, extrudes the silver-plated silver-plated silver-plated silicon rubber, graphite filled out of silicon rubber, glue copper of filling out of silicon rubber, nickel of filling out of liner aluminium and fill out silicon rubber and fine silver and fill out silicon rubber silver and fill out silicon rubber etc.
Conductive rubber has good electromagnetic sealing and water vapor seal ability, and good electroconductibility (blanketing frequency reaches 40GHz) can be provided under certain pressure.Product meets the standard MIL-G-83528 of U.S. army widespread use in the fields such as electronics, telecommunications, electric power, military project, Aeronautics and Astronautics, naval vessel.This product mainly be take high performance silicon rubber as base-material, joins special type filler (as silver-plated in copper, aluminium is silver-plated, glass silvering, graphite nickel plating particle etc.) and auxiliary agent, and is made through strict controlled technique, and volume specific resistance can reach 0.004 Europe * centimetre, good stability.
Conductive rubber typically refers to volume resistance in 9 ohmcms of 10, because rubber is good isolator, and 14 left and right that volume resistance is greater than 10.The conductive rubber that graphitized carbon black is filled, volume resistance can remain on several kilo-ohms conventionally, and owing to having used single Shawinigan black in existing formula, its tensile strength can only reach 12Mpa, can not meet actual needs far away.
Summary of the invention
It is large that technical problem to be solved by this invention is to provide a kind of tensile strength, and what conduct electricity very well can conductive rubber.
For solving above technical problem, a kind of energy of the present invention conductive rubber, the weight part of each component is as follows:
