Abstract

A fireproof heat insulating board including a foamed resin molded body filled with a slurry, the foamed resin molded body having continuous voids, wherein the filled slurry forms a hydrate containing water of crystallization in an amount of 50 kg/m 3 or more through hydration reaction after the filling, and at least a part of the surface of the board is reinforced with one or more inorganic fibers selected from the group consisting of a basalt fiber and a ceramic fiber.

First claim

1 . A fireproof heat insulating board comprising a foamed resin molded body filled with a slurry, the foamed resin molded body having continuous voids, wherein
the filled slurry forms a hydrate containing water of crystallization in an amount of 50 kg/m 3 or more through hydration reaction after the filling, and at least a part of a surface of the board is reinforced with one or more inorganic fibers selected from the group consisting of a basalt fiber and a ceramic fiber.

2 . The fireproof heat insulating board according to claim 1 , wherein the hydrate contains one or more selected from the group consisting of gypsum dihydrate and ettringite in an amount of 50% by mass or more.

3 . The fireproof heat insulating board according to claim 1 , wherein the foamed resin molded body comprises one or more selected from the group consisting of a foamed polyurethane resin, a foamed polystyrene resin, a foamed polyolefin resin, and a foamed phenolic resin.

4 . The fireproof heat insulating board according to claim 1 , wherein a continuous void ratio of the foamed resin molded body is 25 to 70% by volume.

5 . The fireproof heat insulating board according to claim 1 , wherein the fireproof heat insulating board has a density of 250 to 800 kg/m 3 .

6 . A fireproof heat insulating structure comprising the fireproof heat insulating board according to claim 1 .
