Functional inorganic board and manufacturing method thereof

摘要

The present invention relates to an inorganic board comprising a base layer containing magnesium-based inorganic materials and phase change materials, and to a method for producing the board. The inorganic board of the present invention employs magnesium-based inorganic materials instead of plaster used in conventional boards, and thus improves the strength and water resistance thereof as compared to conventional plaster boards. Accordingly, the board of the present invention is formed so as to be thin, and the content of the phase change materials in the base layer increases by the superior blending ratio of magnesium-based inorganic materials and phase change materials, thus maintaining the indoor temperature of the structure constructed by the board of the present invention at a comfortable level. Therefore, the inorganic board of the present invention can be effectively used in interior materials or the like for a building, which require strength and water resistance properties.

主权项

1. An inorganic board comprising:
a base layer containing a magnesium-based inorganic material and a phase change material, a density of the magnesium-based inorganic material and a density of the phase change material are about the same, with the densities of the magnesium-based inorganic material and the phase change material being 0.8-1.0 g/cm3; a surface layer formed on one or both sides of the base layer and comprising at least one selected from the group consisting of paper, glass fiber, cellulose, and polyester fiber; and a glass fiber reinforcing layer between the base layer and the surface layer, wherein the magnesium-based inorganic material comprise mixtures of magnesium oxide and magnesium chloride.
