無機質板の製造方法
Document Type and Number:
Japanese Patent JP3980183
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing an inorganic board, intended to improve the mechanical strength of a mat subjected to forming by dry process so as to ensure the mat not to get out of shape. SOLUTION: This method for producing an inorganic board comprises the following process: a stock mixture comprising a hydraulic material, a woody material and a powdered thermosetting resin is prepared without using any water and then subjected to forming on a mat followed by hot pressing to effect melt curing of mainly the powdered thermosetting resin; subsequently, such an amount of water as to be necessary for hardening the hydraulic material is fed to the resultant mixture followed by performing an autoclave curing; therefore, the alkaline component in the hydraulic material is not leached during the hot pressing process and the thermosetting resin is cured smoothly.
