Abstract

A heat-absorbing material including particles including a magnesium phosphate hydrate and a binder.

First claim

The invention claimed is:

1. A heat-absorbing material comprising particles comprising a magnesium phosphate hydrate and a binder, the amount of the magnesium phosphate hydrate being 70 to 99 wt %.

2. The heat-absorbing material according to claim 1 , wherein the magnesium phosphate hydrate is magnesium phosphate tribasic octahydrate.

3. The heat-absorbing material according to claim 1 , wherein the binder is an inorganic binder.

4. The heat-absorbing material according to claim 1 , wherein the binder is sodium silicate.

5. The heat-absorbing material according to claim 1 , wherein the particles have an average diameter of 0.01 mm to 20 mm.

6. The heat-absorbing material according to claim 1 , wherein the particles are accommodated in a container.

7. The heat-absorbing material according to claim 6 , wherein the container comprises a heat-resistant cloth.

8. The heat-absorbing material according to claim 7 , wherein the heat-resistant cloth is a glass cloth, a silica cloth or an alumina cloth.

9. A heat-absorbing material comprising particles comprising a magnesium phosphate hydrate and a binder, wherein the particles are accommodated in a container that comprises a heat-resistant cloth, the heat-resistant cloth is a glass cloth, a silica cloth or an alumina cloth, and the heat-resistant cloth is a cloth with aluminum being deposited on a surface thereof.

10. The heat-absorbing material according to claim 6 , wherein a plurality of the containers are serially connected to each other.

11. A method of producing the heat-absorbing material of claim 1 , comprising;
mixing a magnesium phosphate hydrate and a liquid glass to form a mixture,
granulating the mixture to form hydrous particles, and
removing water from the hydrous particles to obtain particles.

12. The method according to claim 11 , further comprising accommodating the particles in a container.

13. The heat-absorbing material according to claim 8 , wherein the binder is sodium silicate.

14. The method according to claim 11 , further comprising accommodating the particles in a container that comprises a heat-resistant cloth, and the heat-resistant cloth is a glass cloth, a silica cloth or an alumina cloth.

15. The method according to claim 14 , wherein the heat-resistant cloth is a cloth with aluminum being deposited on a surface thereof.
