Description
Technical field
The present invention relates in the caused by spinning industrial production textile materials be carried out vacuum splashing and plating and the method for electroless plating composite manufacturing making electromagnetic wave screen fabric and the high-performance electromagnetic wave shielding fabric that makes in this way, product can be widely used in industrial fields such as military project, scientific research, workers and peasants doctor, and the shielding and the protection of the household electrical appliance unwanted electromagnetic wave of common people family.
Background technology
The textile materials that electromagnetic wave shielding is used has wire cloth, wire and textile yarn interweave or the embedding woven fabric, the blended fabric of steel fiber or carbon fiber and conventional textile fibres, plated metal film fabric, the chemical plating metal film fabric, vacuum metallization film fabric etc.In above-mentioned numerous electromagnetic wave shielding textile materials, wire cloth and wire interweave or the embedding woven fabric emerges the earliest.Wire mainly adopts copper wire, nickel wire or Stainless Steel Wire, and its fabric shield effectiveness is better, in 0.15MHz～20GHz scope, can reach 〉=60dB, but fabric is thick and heavy, firmly, not folding.As a radar operation soldier's the protective clothing 9kg that just weighs.Steel fiber and conventional textile fibres BLENDED FABRIC are metal (mainly being nickel or stainless steel) to be pumped into fibrous, are made into cloth with 5%～20% left and right sides ratio after with textile fibres blending resultant yarn.This class textile materials is lighter, and wear behavior makes moderate progress, and feel is soft, and chromatogram is also more.But because steel fiber is than great, cohesive force is little, is difficult to the spinning high grade cotton yarn, and effectiveness of shielding only reaches 15～30dB in 0.15～3GHz scope, far inferior to the wire cloth and the embedding woven fabric that interweaves thereof.Plated metal fabric cost is lower, but the compactness of metallic membrane, the too late vacuum plating of homogeneity and electroless plating fabric, feel is also poor, and fabric is harder, not folding.Owing to electroplate is that the mat electric current makes the reduction of solution metal ion being formed metallic membrane by the plating substrate surface, so be used for metallizing and plastics morely, seldom is used to plate the very big fabric of surface-area.And electroplating technology produces a large amount of waste water, and is seriously polluted.The chemical plating metal fabric has good shield effectiveness, and is soft, good permeability, and waste water is less, but chemical plating technology is more complicated.The stability of chemical plating fluid is difficult to control, especially electroless copper.The electroless plating of textiles is based on copper facing, nickel plating and silver-plated at present.The effectiveness of shielding of electroless copper, silver coating fabric can reach 〉=60dB in 0.15MHz～20GHz scope, and the effectiveness of shielding of chemical nickel plating fabric can reach 40～60dB in 0.15MHz～20GHz scope.The vacuum splashing and plating metal fabric also has a good protection effect with chemical metal-coated fabric is the same, and the gained metallic membrane is finer and close evenly, and ventilation property might as well.Nearly all metal all can be used for sputter, and technology is simple, and whole technological process does not have the three wastes and produces.But the sputter rete is very thin, and it is very uneconomical to reach the above effectiveness of shielding of 60dB, and cost is high, and applying of vacuum splashing and plating fabric is very limited.ZL97106422.7 is the manufacture method that Chinese patent has proposed a kind of radiation-proof fabric, it is characterized in that base material is the synthetic fibre mixed fabric that polyblends of elemental substances such as general fibre and carbon containing, barium, its material is activated, sensitization handles that the back is silver-plated with chemical plating method, copper, nickel etc., do cylinder or PLATE SCREAM PRINTING processing with the acrylate thickener seal slurry of multiple elemental substances such as siliceous, carbon, sodium, niobium, lithium, iron more subsequently, this fabric has good absorptive character to hertzian wave, and 40～60dB decays in 30～1000MHz scope.
Above-mentioned all kinds of electromagnetic wave screen fabric all can't integrate flexibility, environmental protection, economy, high-effect, and none method can obtain the electromagnetic shielding effectiveness of flexible fabric more than wideband segment limit 90dB.
Summary of the invention
Be the deficiency of avoiding above-mentioned electromagnetic wave screen fabric to exist, obtain the above high effectiveness of shielding of 90dB in the wideband segment limit, the flexible high-performance electromagnetic wave shielding fabric that the invention provides a kind of vacuum sputtering coating and plated film compound manufacture method and make by rationally the inlaying of this compounding technology, cooperation, synergy.

Embodiment
The principle of vacuum splashing and plating is a metal targets of utilizing the energetic particle hits shielding electromagnetic wave to use, do energy exchange after, sputter atom or molecule deposition from target material surface and form metallic film to the textile substrate substrate.Primary process is such: utilize discharge to make the gas that feeds vacuum chamber excite the generation plasma body, contain the electronics and the ion that are ionized out in this plasma body, they are in higher-energy state.Positive ion is driven target out of under effect of electric field.After doing energy exchange, the state of target with atom or molecule sputtered out, fly to the textile substrate substrate, and be deposited on the film that substrate forms shielding electromagnetic wave with the atom of target material surface or molecule.The result of mass spectroscopy shows that most sputtering particles are the monatomic of target material, though there is the part sputtering particle can be in the discharge space ionization, ratio be very little, generally only accounts for about 1%.So their electromagnetic shielding effectiveness is directly based on atoms metals such as copper, silver.Because sputtering coating target does not have phase transformation, the compound composition is difficult for changing, and alloy also is difficult for taking place fractionation, and therefore the plated film that uses is very extensive with material.And sputtering sedimentation is 50 times that evaporation coating produces particle energy to the particle energy on the substrate, so the electromagnetic shielded film that is formed by sputtering particle can adhere on fabric very securely.
Chemical plating principle is to adopt reductive agent to make the metal ion reduce deposition form metallic membrane, must be before the fabric plated film through abundant pre-treatment, remove impurity such as grease, dirt, polyester piece good need be made the alkali decrement treatment, to improve the attachment fastness of coating and base material.The present invention adopts the conventional chemical coating process, generally comprises catalysis, activation, three primary processes of plated film.
Can directly enter plated film behind the fabric vacuum splashing and plating film and bathe, can save the preceding necessary catalysis of former plated film and two processes of activation.Also technology can be adjusted into first plated film vacuum sputtering coating again, can save like this and go up this process of protective layer after the electroless plating, but can not save catalysis and activation before the plated film.
