Abstract
The invention relates to a super shielded cable with the functions of electromagnetic shielding, electromagnetic compatibility, electromagnetic interference resistance, high-low frequency shielding, electrostatic shielding, information leakage prevention, lightning induction electromagnetic shielding and the like. The principle of the adoption of an anti-radiation alloy material (patent application number: 200910147486.0) is adopted to control the induction and the radiation of electromagnetic interference and electromagnetic wave from one region to another region so as to manufacture the super shielded cable for realizing shielding. The super shielded cable is applied to control lines of igniters of modern airplanes, missiles, tanks and warships in military, and also applied to national defense communication cables, undersea cables, computer network lines and control lines of various kinds of equipment.
Description
Affiliated technical field: electromagnetic shielding, electromagnetic compatibility
The technical problem that solves: prevent electromagnetic interference, anti electromagnetic wave, low-and high-frequency shielding, electrostatic screen, lightning induction electromagnetic shielding, prevent information-leakage etc.
Manufacture method: the place that the manufacture method of super shielded type cable is different with common shielded type cable manufacture method is a screen.The screen of super shielded type cable is to adopt the anti-radiation alloy material (patent No.: 200910147486.0) be processed into wire and metal dust for raw material.Diameter wiry decides according to the screening effectiveness dB of cable, because screening effectiveness dB is relevant with the thickness and the density of screen, the effect of shielding is good more, and the screen of employing is thick more, so the diameter wiry of processed finished products is complementary according to the requirement of shielded type cable.
The processed finished products granularity of metal dust is 80nm, and heating 500 ℃ through vacuum dehydrogenation stove is incubated 1 hour, and (manufacture method is seen Appendix: the radiation shielding coating specification) to be processed into radiation shielding coating then.The wire of processed finished products will intensification 425-650 ℃ of annealing be incubated 1 hour in vacuum dehydrogenation stove, to recover conductivity.
The manufacture method of screen: adopt the wire of wire knitting machine utilization after vacuum dehydrogenation stove is handled that the cable through cabler is carried out 360 shielding braids of spending, with the radiation proof material that processes the screen that weaves is sprayed then.Notice that spraying must evenly will make the crosspoint of line and line and metal coating be connected to form sealant, thus assurance high conductivity and shielding preferably.Be cured through heating tube, coating through plastic extruding machine at last.Super shielded type cable can carry out bilayer or multilayer screen.
------spraying---is solidified---plastic extruding machine coating---finished product---check---warehouse-in to shielding braid in technological process: coat stranding
Main application: be used for power on control circuit on the control circuit, national defence communication cable, computer network lines, submarine cable, various device of igniter of modernized aircraft, guided missile, tank and warship in the military affairs.
Attached: the radiation shielding coating specification
Affiliated technical field: electromagnetic shielding, electromagnetic compatibility
The technical problem that solves: prevent electromagnetic interference, anti electromagnetic wave, low-and high-frequency shielding, electrostatic screen, lightning induction electromagnetic shielding, prevent information-leakage etc.Raw material proportioning (mass parts):
Acrylic resin 25 butyl acetates-dimethylbenzene (5: 3) 80
Radiation proof alloy powder 100
Compounding method: at first the powder that anti-radiation alloy material is utilized the laser ablation method make under vacuum condition carries out surface treatment, get 5 parts in KH560 type silane, adding acetone mixes for 100 parts at normal temperatures, stir and obtain surface conditioning agent, with granularity is that the radiation proof alloy powder of 80nm is put into the surface conditioning agent for preparing, can reach the dispersion requirement in 8 minutes with ball mill grinding, filter out unnecessary solvent then, 60 ℃ of oven dry down.
The coating preparation: film-forming resin selects for use acrylic resin, solvent to select the mixed liquor of butyl acetate and dimethylbenzene for use, and the proportioning of solvent is a butyl acetate: dimethylbenzene=5: 3.Raw material in above-mentioned 3 grinding in ball grinder 20 minutes, can be reached the requirement of dispersion, make finished product.
Material combination:, make conductive filler with nanoscale radiation proof alloy powder according to the characteristic of electromagnetic wave shielding theory and radiation proof alloy powder.This coating component comprises film-forming resin, nanoscale radiation proof alloy powder and coupling agent.Each percentage formula range of forming part is film-forming resin 16.7-23.1, radiation proof alloy powder 75.4-78.3 coupling agent 1.5-5.
Film-forming resin is selected a kind of in epoxy resin, polyurethane, phenolic resins, the acrylic resin for use.
Solvent can be selected a kind of in ethyl acetate, toluene, acetone, ethanol, methyl alcohol, methylethylketone, methyl acetate, the butyl acetate for use.
Coupling agent can be selected a kind of in titanate esters, the silane coupler for use.
This product is used: is used for shielding electromagnetic wave, can be used on the electromagnetic equipment of needs shielding, and indoor shielding.
Product performance: the coating that is provided can be greater than 70dB, at 1KHZ at the electromagnet shield effect of 1-1000KHZ low frequency range---in the 1000MHZ wideband section, balanced electromagnet shield effect is arranged all.
