Document Type and Number:
Japanese Patent JPH11227095
Kind Code:
A
Abstract:
To provide a fire-resistant composite flooring material, which is lightweight, and excellent in fire resistance and processability, and has high hardness by using a gypsum for flooring material.
A fire-resistant composite flooring material 7 is composed by adhering a reinforcing layer 4 composed of a thermosetting resin and an inorganic fiber on a gypsum board 3, or at least one side of a front side 71 or a back side 72 of the gypsum sheet. A thickness of the gypsum board 3 or the gypsum sheet is 9.5-25.0 mm, and a specific gravity of the gypsum board 3 or the gypsum sheet is 0.9-1.5. And a bend strength of the gypsum board 3 is preferably 80-350 kgf/cm2, and a Young's modulus in flexure thereof is preferably 35,000-70,000 kgf/cm2.
