Abstract
The invention discloses a conductive rubber composite material which comprises the following components in parts by weight: 80 parts of silicon rubber, 30 parts of carbon fiber, 8 parts of polyethylene glycol, 25 parts of coppered glass fiber, 6 parts of vulcanizing agent and 5 parts of an anti-aging agent. The conductive rubber composite material disclosed by the invention is excellent in conductivity and electric shielding property.
Description
Technical field
The present invention relates to a kind of rubber composite, particularly relate to a kind of conductive rubber composite material.
Background technology
In recent years, along with developing rapidly of electronic industry and information technology, the electromagnetic interference problem produced between electronic product is more and more obvious.The problems such as electromagnetic interference, electromagnetic radiation and electrostatic bring very large impact to daily life and industrial and agricultural production.How effectively the problem such as electromagnetic interference, electromagnetic radiation reduced between electronic product becomes the focus of various countries expert research, electromagnetic shielding (EMS) is one of most basic skills of controlling of electromagnetic interference shielding, its function has two: one to be the hertzian wave controlling inside, radiation areas, does not make it run off a certain region; It two is prevent external radiation from entering a certain region.By absorbing, reflection and multipath reflection, electromagnetic energy is depleted in communication process can not the degree that normally works of interference Instrument.
Conductive rubber composite material, with its good electroconductibility, ductility, elasticity, environmental sealing and medium corrosion resistance, is widely applied in EMS field.Such material gives its conducting function by adding conductive filler material in rubber matrix.At present, the research improving conductive rubber performance mainly concentrates on the aspects such as the modification to rubber matrix, the improvement to conducting filler and preparation technology's improvement.And conducting filler is as the functive of conductive rubber, the EMS usefulness of quality to product of its performance has the greatest impact.This functive is mainly divided into carbon conductive filler and me tallic conductive filler two class.
For carbon system, traditional carbon black and graphite cannot give the sufficiently high conductivity of rubber to realize electromagnetic shielding, even if also cannot meet the needs of high shielding properties with conductive rubber prepared by the good acetylene carbon black of conductivity or conductive carbon black.For me tallic conductive filler, traditional shielding filler be generally the metal of high conductivity or high magnetic permeability as silver powder, nickel powder, copper powder etc., but the problem such as the expensive and density of this kind of filler ubiquity is large, thus make it apply to be restricted.
Novel shielding filler is more prone to compound powder, as silver/copper powder, silver/nickel, silver/aluminium, silver/glass microballon etc., they are filled into after in rubber, the volume specific resistance of rubber can be reduced to 10-2 ~ 10-3 Ω .cm, make the conductivity of rubber close to metal, thus there is significant electromagnet shield effect.At present, the research abroad in this is very ripe, reaches industrialization level, and the domestic plating Ag composite particles for high conduction performance also main dependence on import.In addition, the research of nickel plating series composite particles and conductive rubber thereof is also actually rare.Therefore, development of new conductive composite particle, preparation Novel conductive rubber are still the focus of various countries expert, scholar's research.
Summary of the invention
The object of the invention is to provide a kind of electromagnetic shielding conductive rubber composite material.Conductive rubber composite material provided by the invention has good conduction and electric shielding performance.
For reaching above-mentioned purpose, the present invention adopts following technical scheme:
A kind of conductive rubber composite material, by weight containing 80 parts, silicon rubber, 30 parts, carbon fiber, polyoxyethylene glycol 8 parts, 25 parts, copper facing glass fibre, vulcanizing agent 6 parts, protective agent 5 parts; In described copper facing glass fibre, the content of copper is 35wt%; Described vulcanizing agent is PDM; Described anti-aging agent is 4.4 a pair ofs (2.2-dimethyl benzyl) pentanoic.
