Abstract

A metallized textile web includes a homogeneous metal layer on the textile web and is as flexible as the textile web itself, wherein the textile web itself can be composed of glass fibers, synthetic resin fibers, carbon fibers, etc., and the composite metallized textile web is suitable for wallpaper-like metallic lining of a space. The metallized textile web provides a material which forms an electronically impermeable Faraday'"'"'s cage and at the same time is elastic and vibration- and displacement-secure so as to provide electronic release of respective structures. A first metal layer is applied by spraying of a rod metal melted in electric arc to form spider-like microscopic metallic parts on a workpiece, and then a second metal layer is applied by spraying of metal powder melted in a gas flame for forming ball-shaped or droplet-shaped particles, so that the "spider legs" of the spider-like metal particles engage in one another and provide an elastically flexible metal cover while the metal balls seal them and provide electronically impermeable structure.

Claims

1. A metallized textile web comprising a textile web having a web surface;

a first polymer adhesive agent layer applied on said web surface of said textile web and composed of a dried latex enriched with powdered quartz, acrylic acid and alkyd resin;

a second adhesive agent layer applied on said first adhesive agent layer and composed of a dried water dispersion of powdered quartz and sugar;

a first metal layer applied on said second adhesive agent layer and composed of a metal in form of spider-shaped microscopical individual particles; and

a second metal layer applied on said first metal layer and composed of the same metal in form of ball-shaped or droplet-shaped microscopic particles.

2. A metallized textile web as defined in claim 1, wherein the metal of said metal layers is selected from the group consisting of copper, aluminum, silver and iron.

3. A metallized textile web as defined in claim 1, wherein said first adhesive agent layer is a water-resistant layer and includes the following ingredients:

space="preserve" listing-type="tabular">______________________________________ latex 35 weight % water 23 weight % powdered quartz 23 weight % water-soluble polyvinylchloride 9 weight % acrylic acid 7 weight % hydrosol 2 weight % alkyd resin lacquer 1 weight %. ______________________________________

4. A metallized textile web as defined in claim 3, wherein said latex is a fine dispersion of a polymer, said water being softened water, said hydrosol being an aqueous dispersion of acrylic acid and monostyrene, and said alkyd resin lacquer being linseed oil and polyalcohol.

5. A metallized textile web as defined in claim 1, wherein said second adhesive agent layer is a water-soluble adhesive agent layer and composed of the following ingredients:

6. A metallized textile web as defined in claim 5, wherein said water is a softened water, said sugar solution being sugar and water in equal weight, said glue being wallpaper glue, said metal powder being nickel powder.

7. A method of producing a metallized textile web, the method comprising the steps of providing a textile web having a web surface;

applying on the web surface a first polymer adhesive agent layer composed of dried latex enriched with powdered quartz, acrylic acid and alkyd resin;

applying on said first adhesive agent layer a second adhesive agent layer composed of dried water dispersion of powdered quartz and sugar;

applying on said second adhesive agent layer a first metal layer composed of a metal in form of spider-shaped microscopic individual particles; and

finally applying on said first metal layer a second metal layer composed of the same metal in form of ball-shaped or droplet-shaped microscopic particles.

8. A method as defined in claim 7, wherein said steps of applying the metal layers includes applying the metal layer composed of the metal selected from the group consisting of copper, aluminum, silver and iron.

9. A method as defined in claim 7, wherein said step of applying the first adhesive agent layer includes applying the first adhesive agent layer in form of a water resistant layer with the following ingredients:

space="preserve" listing-type="tabular">______________________________________ latex 35 weight % water 23 weight % powdered quartz 23 weight % water-soluble polyvinylchloride 9 weight % acrylic acid 7 weight % hydrosol 2 weight % alkyd resin lacquer 1 weight %. ______________________________________

10. A method as defined in claim 9, wherein said step of applying the second adhesive agent layer includes applying the first adhesive agent layer in which the latex is a fine dispersion of a polymer, water is softened water, the hydrosol is an aqueous dispersion of acrylic acid and monostyrene, and the alkyd resin lacquer is linseed oil and polyalcohol.

11. A method as defined in claim 7, wherein said step of applying the second adhesive agent layer includes applying the adhesive agent layer as a water-soluble layer with the following ingredients:

space="preserve" listing-type="tabular">______________________________________ relieved water 35 weight % powdered quartz 33 weight % sugar solution 13 weight % water soluble polyvinylchloride 9 weight % glue 7 weight % metal powder 3 weight %. ______________________________________

12. A method as defined in claim 11, wherein said step of applying the second adhesive agent layer includes applying the second adhesive agent layer in which the water is softened water, the sugar solution is sugar and water with equal weight, the glue is wallpaper glue, and the metal powder is nickel powder.

13. A method as defined in claim 7, wherein said steps of applying the adhesive agent layers include first applying the adhesive agent layers and then drying the adhesive agent layers, said step of applying the first metal layer including applying the first metal layer after the drying of the adhesive agent layers and by spraying the metal of a metal wire melted in electric arc without oxygen, by means of a spraying gun.

14. A method as defined in claim 13, wherein said step of applying the second metal layer includes applying the metal in form of metal powder by a spraying gun in gas flame.

15. A method of producing a metallized textile web as defined in claim 7, comprising the step of subsequently spraying an adhesive upon the non-metallized side of the textile web.
