The present invention has the advantages of being light, ventilating, transparent, non-toxic, fireproof, etc. and is especially suitable for use in fields needing shield on strong electromagnetic wave.
Description
Technical field:
The invention belongs to the technical field of Textile Engineering, specifically a kind of relating to, need the shielding electromagnetic wave occasion to use or the fabric manufacturing of dress.
Background technology:
Present shielding electromagnetic wave fabric, the zinc-plated and copper fabric as SHIELDEX, SUPRA, shield effectiveness is 100 decibels when frequency 100MHz; Japan " fiber process " NO.11p27-41 in 2000, screen magnetic field is the 6-46 decibel in 10-1000MHz.Above-mentioned shielding electromagnetic wave fabric, in some high strong-electromagnetic field field, just powerless, bring injury can for so undoubtedly object or human body, cause part fails even paralysis, work hard to carry on, so also need to make the flexible fabric that can shield high strong-electromagnetic field, just can meet the need of market.
Summary of the invention:
The object of the present invention is to provide a kind of compliant conductive fabric, it can the high strong-electromagnetic field of shielding electromagnetic wave in the 0.15MHz-20GHz frequency range.
To achieve these goals, technical scheme of the present invention is: a kind of compliant conductive fabric, mainly comprise its outer metal alloy coating of base cloth and parcel, it is characterized in that: the base cloth of described compliant conductive fabric is formed by weaving by the metal fibre of 35-45% and the cotton fiber of 55-65%, and the metal alloy coating of appearance is divided into bottom and outer two levels.
A kind of manufacture method of compliant conductive fabric is characterized in that: the manufacture method of described compliant conductive fabric may further comprise the steps, and a, is formed by weaving base cloth by the metal fibre of 35-45% and the cotton fiber of 55-65%; B, base cloth is entered the sensitization that is made into by stannous chloride 5-15g/L and hydrochloric acid 10-30ml/L bathe; C, taking-up are after twice of running water rinsing; D, directly immerse the chemical plating silver bath that first bath promptly contains by silver nitrate 3-8g/L and ammoniacal liquor 5-10ml/L and form bottom; E, immerse second again and bathe, by water and formaldehyde 6: 1-15: 1 synthetic reducing bath; F, with immersion plating have silver base cloth again through secondary water washing; G, enter in the alloy electroplating bath then, the infiltration plating through 10-30 minute becomes bottom and outer two levels; Be made as finished product after h, twice of rinsing again, the oven dry.A kind of compliant conductive fabric is woven into base cloth by the metal fibre of 35-45% and the cotton fiber of 65-55%, carry out chemical method silver-plated after, chemical nickel plating, copper, ferroalloy form again, fabric adopts honeycomb to improve effective thickness.
The present invention is owing to doing to take into full account aspect the effective thickness that improves the shielding properties to electromagnetic field, the snap-in force that improves metal level and fabric and raising compliant conductive fabric, fruitful active measures have been taked, possess soft, ventilation, printing opacity, nontoxic, can be fire-retardant etc. series of advantages, being adapted to military project scientific research, Aero-Space, industrial enterprise, health care etc. especially needs the need in the strong electromagnetic wave field of shielding electromagnetic wave in the 0.15MHz-20GHz frequency range to use.
The specific embodiment:
Below in conjunction with embodiment the present invention is further described.
The present invention mainly comprises base cloth and metal alloy coating, select for use the metal fibre of 35-45% and content up to the cotton fiber more than the 65-55% in the base cloth, iron-holder is up to 20-25% in the metal fibre of base cloth, and purpose is that the shielding properties that improves magnetic field is also sturdy and durable; The cotton fiber of high-load in the base cloth is in order to improve the snap-in force of metal level and fabric, to increase the flexibility of fabric, being convenient to be made as ready-made clothes or object outer cover etc. and making articles for use; Fabric employing alveolate texture has improved the effective thickness of compliant conductive fabric, armoured magnetic field effectively.The iron content of metal fibre is 20-25%, C0.02-0.05%, Si0.05-1.5%, S0.06-1.5%, Cr16-18%, Ni10-14%, Mo2-3% in the base cloth.Metal alloy coating of the present invention is divided into bottom and outer two levels, and chemistry soaks silver and is bottom, and method is that base cloth at first enters the sensitization bath that is made into by stannous chloride 10g/L and hydrochloric acid 20ml/L; Take out after first bath is directly immersed in running water rinsing twice, also both by silver nitrate 5g/L and the synthetic chemical plating silver bath of ammoniacal liquor 7ml/L; Continue to immerse second again and bathe, by water and the synthetic reducing bath of formaldehyde (as 9: 1).Because it is not self-catalyzed reaction that chemistry soaks silver, can only plate very thin one deck, shield effectiveness also is nowhere near.Need the skin of chemical nickel plating, copper and ferroalloy again, make its composition as far as possible near permalloy, in order to improve shielding strong-electromagnetic field function of the present invention.The outer layer alloys electroplate liquid formulation is: copper sulphate 10-12g/L, nickelous sulfate 40-45g/L, ferric sulfate 10-15g/L, natrium citricum 40-45%, ammonium chloride 30-35g/L, sodium acetate 35-40g/L, inferior sodium phosphate 25-30g/L, potassium borate 10-12g/L, pH value are between 9-11, and temperature is controlled between 40-45 ℃.Soak be coated with bottom behind the silver base cloth after secondary water washing, just can enter in the plating bath of above-mentioned alloy formula, after 10-30 minute infiltration plating, metal alloy coating is divided into bottom and is made as finished product with outer two level clear water twice of rinsings again, oven dry.Except corresponding mixture ratio or time parameter, all be considered as prior art about the sensitization bath in the manufacture method, silver plating bath, reducing bath, do not specify at this, this fabric resistance value is 1 * 10
-6Ω/cm, electromagnetic wave is in the 0.15MHz-20GHz frequency range, shield effectiveness reaches the 90-120 decibel, armoured magnetic field reaches the 40-50 decibel, formed soft, ventilation, printing opacity, nontoxic, can be fire-retardant etc. series of advantages, be specially adapted to the needs that military project scientific research, Aero-Space, industrial enterprise, health care etc. need the field of shielding strong electromagnetic waves.
