PRODUCTION PROCESS FOR CEMENTED WOOD BOARD

摘要

PROBLEM TO BE SOLVED: To provide a production process for a cemented wood board which has excellent adhesion to a coating film and remarkably improved dimensional stability and, in which no microcrack is caused, even when the board contains mica. SOLUTION: This production process comprises preparing a raw material mixture that consists essentially of a wood reinforcing material and a cement- based inorganic material and also contains powdery mica which has a >=150μm average particle size and has an aspect ratio (length/thickness) of >=65, spraying the raw material mixture on a plate to form a mat, and clamping the mat and subjecting the clamped mat to autoclave curing at >=60 deg.C, in the presence of water.
