Abstract
A flame-retardant metal-coated cloth having a high degree of flame retardancy and a soft feeling without the use of any halogen compound or antimony compound is provided. In the flame-retardant metal-coated cloth, a flame-retardant film comprising a mixture (E) of a phosphorus compound (A), a metal hydroxide (B), a phosphoric ester (C), and a thermoplastic resin (D), is formed on at least one surface of a metal-coated cloth, and the ratio of (A):(B):(C):(D) is 20 to 200:100 to 950:10 to 250:100 in terms of a weight ratio.
Claims11
A flame-retardant metal-coated cloth, comprising:
- a metal-coated cloth having a first surface and a second surface, the metal coated cloth comprising a synthetic fiber;
- and
- a flame-retardant coating provided over the first surface;
- wherein the flame-retardant coating comprises a mixture (E) of a phosphorous compound (A), aluminum hydroxide (B), a phosphoric ester (C), and a thermoplastic resin (D), characterized in that the ratio of (A):(B):(C):(D) is 20 to 200:100 to 400:10 to 250:100 in terms of a weight ratio,
- wherein the weight of the flame-retardant coating formed by the mixture (E) is 100 to 300% by weight based on the weight of the metal-coated cloth,
- wherein the flame-retardant coating does not include a halogen compound or an antimony compound,
- wherein the thermoplastic resin is capable of dissolving in benzene, toluene, xylene, methyl ethyl ketone or dimethyl formamide to form the coating solution having a viscosity of 3000 to 25000 cps,
- wherein the flame-retardant metal-coated cloth has a thickness of 100 to 300 μm,
- wherein the flame-retardant metal-coated cloth has an acceptable VTM-0 flame retardancy when the flame-retardant metal-coated cloth is evaluated in accordance with UL94, VTM-0 Testing Method,
- wherein the flame-retardant metal-coated cloth has a rigidity/softness value of 42 mm to 84 mm measured by a 45° Cantilever Method in accordance with JIS-L-1096.
