Abstract
The present application is directed to a novel composition which acts as a barrier to noxious agents while adding self-detoxifying catalytic treatments to neutralize the noxious and harmful warfare agents when applied for example on a fabric, or other solid support.
Claims41
A composition for protection against harmful or noxious agents comprising:
- a) from 1 to 95% by weight of a porous media;
- b) from 2 to 60% by weight of an aliphatic amine or hydrophilic amine polymer or monomer;
- and,
- c) from 10 to 90% by weight of water.
1 more element
A method of preparing a laminated support comprising the steps of:
- a) mixing together from 1 to 95% by weight of a porous media, from 2 to 60% by weight of an aliphatic amine or hydrophilic amine polymer or monomer, from 0 to 90% by weight of a polyvinyl acetate polymer or copolymer, from 0 to 20% by weight of a polyvinyl alcohol polymer or copolymer, from 0 to 60% by weight of a polyurethane polymer, from 0 to 60% by weight of an acrylic polymer, and from 10 to 90% by weight of water at a temperature between 20 to 100° C.;
- b) adding from 0 to 10% by weight of a surfactant agent, from 0 to 10% by weight of an epoxy resin or of a crosslinking agent, from 0 to 5% by weight of one or more metal salts or oxides, and from 0 to 10% by weight of a defoamer agent to yield a laminate composition;
- c) casting said laminate composition on a solid support to yield said laminated support;
- and
- d) curing said laminated support at a temperature in the range of 100 and 220° C.

A method of preparing a laminated support comprising a carbon fabric, wherein said method comprises the steps:
- a) mixing together from 1 to 95% by weight of said carbon fabric, from 2 to 60% by weight of an aliphatic amine or hydrophilic amine polymer or monomer, from 0 to 90% by weight of a polyvinyl acetate polymer or copolymer, from 0 to 20% by weight of a polyvinyl alcohol polymer or copolymer, from 0 to 60% by weight of a polyurethane polymer, from 0 to 60% by weight of an acrylic polymer, and from 10 to 90% by weight of water at a temperature between 25 to 50° C.;
- b) adding from 0 to 10% by weight of a surfactant agent, from 0 to 10% by weight of an epoxy resin or of a crosslinking agent, from 0 to 5% by weight of one or more metal salts or oxides, and from 0 to 10% by weight of a defoamer agent to yield a laminated support;
- and,
- c) curing said laminated support at a temperature in the range of 100 and 220° C.
