Abstract

This invention relates to a method of manufacturing a salt-coated heat paper, including preparing a powder mixture by mixing a fuel powder with an oxidant powder; preparing a slurry by adding an organic coagulant, after mixing the powder mixture with glass fibers; obtaining a heat paper by a papermaking process utilizing the slurry; primarily drying the heat paper by pressing; coating the heat paper with a salt solution; and secondarily drying the heat paper.

First claim

What is claimed is:

1. A method of manufacturing a salt-coated heat paper, comprising:
preparing a powder mixture by, mixing a fuel powder with an oxidant powder;
preparing a slurry by adding an organic coagulant, after mixing the powder mixture with glass fibers;
obtaining a heat paper by a papermaking process utilizing the slurry;
primarily drying the heat paper by pressing;
coating the heat paper with a salt solution; and
secondarily drying the heat paper, after coating the heat paper with the salt solution,
wherein coating the heat paper with the salt solution enables a combustion temperature of the heat paper to be controlled depending on a number of salt coating processes,
wherein coating the heat paper with the salt solution enables a heating value of the heat paper to be controlled depending on a number of salt coating processes, and
wherein as the number of salt coating processes increases, the combustion temperature is gradually lowered, and physical properties of the salt-coated heat paper are enhanced.

2. The method of claim 1 , wherein the fuel powder comprises at least one selected from among Zr, Fe, Ni, Mg, Ti, W, B, Si, C, S, and P.

3. The method of claim 1 , wherein the oxidant powder comprises at least one selected from among BaCrO 4 , KClO 4 , KNO 3 , BaNO 3 , PbO 2 , Pb 3 O 4 , and CaCrO 4 .

4. The method of claim 1 , wherein a solvent for the salt solution comprises at least one selected from among distilled water, ion exchange water, and an organic solvent.

5. The method of claim 1 , wherein a salt of the salt solution comprises at least one selected from among KCl, NaCl, MgCl 2 , LiCl, LiBr, LiF, NaF, KF, NaOH, NaCl—KCl, and NaCl—KCl—MgCl 2 .
