Description
Technical field
The present invention relates to electromangnetic spectrum fields, and in particular to one kind superconducts EPT rubber packing item.
Background technique
In recent years, with science and technology and electronics industry high speed development, it is various digitlization, high frequency electronic apparatus set
The standby electromagnetic wave for having radiated a large amount of different wave lengths and frequency to space at work, so as to cause new environmental pollution-electromagnetism
Wave interference and radiofrequency interference.The electromagnetic interference that electromagnetic radiation generates not only influences the performance realization of electronic product, but also
Caused electromagnetic pollution can cause serious harm to the mankind and other organisms therefrom.To solve caused by electromagenetic wave radiation
Interference and leakage, mainly shielded using electromagnetic shielding material, realize electronic and electrical equipment mutually reconciled with environment, Xiang Gongcun
Electromagnetic compatible environment.
Currently, conductive rubber in the market, high score base-material mainly uses silicon-based rubber material, although silicon-based rubber material
Material has good electric property, weatherability and high-low temperature resistant stability etc., but their current prices are higher, especially have
The silicon rubber of property, price are higher.
There are also the conductive rubbers of some ethylene propylene diene rubber matrixes production, due to adding a large amount of conductive filler (metal powder
The accountings such as end are 70% or more), processing performance is had a greatly reduced quality, and can only be made some molded products, is not able to satisfy extrusion molding
The demand of product.
Summary of the invention
The purpose of the present invention is to overcome the above shortcomings and to provide one kind to superconduct EPT rubber packing item, with low
The EPDM rubber of cost is carrier, only need to add a small amount of conductive filler, has oxidative resistance, ozone-resistant and anti-erosion etc. are excellent
Point, while electric conductivity is very good, can be applied to communication terminal, notebook computer, digital audiovisual and communication equipment etc., with
Meet middle- and high-end applications.
The object of the present invention is achieved like this:
One kind superconducting EPT rubber packing item, the raw material including following mass fraction: EPDM raw rubber is 100 parts, is mended
Strong agent carbon black N550 is 80-160 parts, conductive black is 6-16 parts, plasticizer is 30-100 parts, homogenizing agent is 3-8 parts, zinc oxide
For 5-10 parts, stearic acid be 2-6 parts, surfactant is 1-5 parts, hygroscopic agent is 8-12 parts, vulcanizing agent is 1-2 parts, promotor
It is 3-6 parts.
Preferably, the ratio between mass parts of the conductive black, plasticizer, homogenizing agent are 2:10-18:1.
Preferably, the vulcanizing agent uses sulfur cross-linking system.
Preferably, the plasticizer is paraffin oil, DOP or tri- kinds of DOS mixing.
Preferably, the promotor is tri- kinds of TMTD, DTDM and CZ mixing.
The beneficial effects of the present invention are:
The present invention only need to add a small amount of conductive filler using the EPDM rubber of low cost as carrier, have oxidative resistance, ozone-resistant
And the advantages that anti-erosion, while electric conductivity is very good, can be applied to communication terminal, notebook computer, digital audiovisual and
Communication equipment etc., to meet middle- and high-end applications.
