Abstract
The invention discloses a novel electromagnetic shielding composite material. The novel electromagnetic shielding composite material is made by, by weight, 4-8 parts of carbon black, 0.6-0.8 part of gas-phase silica, 7-18 parts of friction performance regulator, 10-19 parts of soft magnetic material, 12-16 parts of nano magnetic material, 3-6 parts of tricobalt tetraoxide, 7-11 parts of polyvinyl chloride, 3-5 parts of polyethylene wax, 2-4 parts of coupling agent, 15-23 parts of epoxy resin, 13-16 parts of reduced iron powder, 6-15 parts of graphite, 2-6 parts of magnetic colloid and 3-5 parts of 3301 resin. The novel electromagnetic shielding composite material has the advantages of being good in processing performance, stable in friction wear performance, good in heat resistance and low in making cost.
Description
Technical field
The present invention relates to a kind of novel electromagnetic shielding composite material.
Background technology
Along with the development of science and technology, the mankind enter information society, and the electronic electric equipment used aborning gets more and more, and living environment has had dense electromagnetic environment intension.Along with increasing rapidly of urban population, automobile, electronics, communication, computer and electrical equipment enter family in a large number, the electromagnetic energy of electromagnetic wave outside radiation just with annual 7% ~ 14% speed increase, electromagnetic environmental pollution is day by day serious.Electromagnetic shielding is the major technique suppressing electromagnetic interference, and shielding material market competition is growing more intense, and shielding composite, as a kind of Novel shielding material, is subject to the great attention of investigators day by day.Performance perameter for the electromagnetic shielding material of electromagnetic shielding is the key determining effectiveness.Electromagnetic shielding material in the market also has many deficiencies, poor in processability, is subject to environmental corrosion, poor mechanical property, so be further improved.
Summary of the invention
For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of novel electromagnetic shielding composite material, has good processing characteristics, and possesses stable friction and wear behavior and good thermotolerance, and manufacturing cost is lower.
For solving prior art problem, technical scheme provided by the invention is, a kind of novel electromagnetic shielding composite material, and it is made up of the raw material of following parts by weight:
Carbon black 4-8 part, aerosil 0.6-0.8 part, frictional property regulator 7-18 part, soft magnetic material 10-19 part, nano magnetic material 12-16 part, tricobalt tetroxide 3-6 part, polyvinyl chloride 7-11 part, polyethylene wax 3-5 part, coupling agent 2-4 part, epoxy resin 15-23 part, reduced iron powder 13-16 part, graphite 6-15 part, magnetic colloid 2-6 part, 3301 resin 3-5 parts.
The invention has the beneficial effects as follows: novel electromagnetic shielding composite material of the present invention, have good processing characteristics, and possess stable friction and wear behavior and good thermotolerance, manufacturing cost is lower.
