Abstract

A thermogenic sheet combined poultice comprising a thermogenic composition layer capable of generating heat in the presence of air or oxygen and a heat-stable wet pack composition layer; and a process for the production of the thermogenic sheet combined poultice.

Claims

1. A thermogenic sheet combined poultice comprising a heat-stable wet pack composition layer and a thermogenic composition layer capable of generating heat in the presence of air or oxygen, the thermogenic composition layer comprising (1) at least one member selected from the group consisting of alkali metal sulfides and polysulfides and the hydrates thereof and (2) at least one member selected from the group consisting of iron carbide and carbonaceous materials.

2. A thermogenic sheet combined poultice according to claim 1, wherein the alkali metal is a member selected from the group consisting of Li, Na, K, Rb and Cs, and the carbonaceous material is a member selected from the group consisting of carbon black, activated carbon, charcoal, coal, coke, pitch, asphalt and graphite.

3. A thermogenic sheet combined poultice according to claim 1, wherein the wet pack composition layer comprises a base ingredient for wet pack and other ingredients necessary therefor.

4. A thermogenic sheet combined poultice according to claim 3, wherein the other ingredient for wet pack is at least one member selected from the group consisting of tackifiers, softening agents and wetting agents.

5. A thermogenic sheet combined poultice according to claim 3, wherein the base ingredient is at least one member selected from the group consisting of kaolin, bentonite, talc, wax, vaseline, sodium lactate, zinc oxide, boric acid and aluminum silicate, and the other ingredient is at least one member selected from the group consisting of sodium alginate, methylcellulose, carboxyvinyl polymers, carboxymethylcellulose, ethylcellulose, polyvinylpyrrolidone, polyvinyl alcohol, polyvinyl methyl ether, sodium polyacrylate, tragacanth gum, atactic polypropylene, guaiachol, ester gum, natural rubber latex, gelatine, fluid paraffin, silicone, glycerine, propylene glycol, polyethylene glycol, diethyl glycol monoethyl ether, magnesium oxide, sorbitol, xylytol, urea, aluminum acetate, beryllium hydroxide, magnesium hydroxide, calcium hydroxide, barium hydroxide and water.

6. A thermogenic sheet combined poultice according to claim 3, wherein the wet pack composition layer comprises, by weight, 2-21 parts of the base ingredient for wet pack and 79-97 parts of the other ingredients for wet pack.
