Problems solved by technology

[0008] In addition, there are gaskets formed by adding flame retardants other than halogen-containing compounds and antimony compounds to general-purpose synthetic resins, laminating them on the surface of conductive fabrics, and laminating hot-melt resin sheets by lamination. This kind of gasket has the problem that the softness of the fabric is impaired due to the large number of layers, and the number of processing steps is also increased.

preparation example Construction

[0093] Preparation of the mixed treatment liquid is not particularly limited. A method capable of uniformly dispersing and mixing various raw materials may be used. Examples thereof include dispersion mixing by propeller stirring, and dispersion mixing by kneading with a kneader, a drum, or the like.

[0094] The flame-retardant metal-clad fabric of the present invention can be produced by forming a layer composed of the composition (G) on the metal-clad fabric by, for example, a direct coating method, a lamination method, or an adhesive method.

[0095] As a coating method, a common method using a knife coater, a roll coater, a slit coater, etc. can be used.

[0096] After coating the mixed treatment liquid on the metal-coated fabric, the solvent is removed by drying or the like to form a flame-retardant coating layer composed of the composition (G).

[0097] The application amount of the mixed treatment solution on the metal-coated fabric can be set to 100 to 300% by weigh...

Embodiment 1

[0128] (Manufacturing of metal clad fabric)

[0129] After refining, drying and heat-treating the polyester fiber fabric (warp yarn 56dtex / 36f, weft yarn 56dtex / 36f), in the 40 After immersing in an aqueous solution at ℃ for 2 minutes, wash with water. Next, it was immersed in fluoboric acid at an acid concentration of 0.1N at 30° C. for 5 minutes, and then washed with water. Then, it was immersed in a 30° C. electroless copper plating solution containing 7.5 g / L of copper sulfate, 30 ml / L of 37% formalin, and 85 g / L of Rochelle salt for 5 minutes, followed by washing with water. Next, in an electroplating nickel solution containing 300g / L of nickel sulfamate, 30g / L of boric acid, and 15g / L of nickel chloride, at 35°C, at 5A / dm 2 Immerse for 10 minutes at a current density of 10 minutes to wash the nickel after lamination.

Abstract

A metal-coated fabric having excellent electromagnetic-wave-shielding properties. The metal-coated fabric has, on at least one side thereof, a layer made of a flame retardant composition prepared without using any halogenated compound or antimony compound.

Description

technical field [0001] The present invention relates to a metal-clad fabric, in particular to a metal-clad fabric and a gasket used for shielding electromagnetic waves generated by electronic equipment or anti-static. Background technique [0002] In offices or homes, with the rapid popularization of electronic devices, mainly various information terminals, people are worried about the impact of static electricity or electromagnetic waves generated by these electronic devices on other electronic devices or human bodies. In order to prevent these hazards caused by static electricity or electromagnetic waves, excellent electromagnetic wave shielding properties are required. In addition, due to the implementation of the Product Liability Act (PL Act), etc., there is an urgent need for gaskets for electromagnetic wave shielding that conform to UL standards, etc., and have high flame retardancy. [0003] As an example of the gasket for electromagnetic wave shielding, there is a ...
