Abstract

PURPOSE: To prepare the titled board having light weight, excellent water resist ance, weather resistance and mechanical strength, easily, by mixing inorganic powder with raw materials of a polyurethane resin foam, and foam-molding the mixture.
CONSTITUTION: 50W5wt% of raw materials of a polyurethane resin foam are mixed with 50W95wt% of inorganic powder having the size of ≤100μ and foam-molded to give a goard having a specified gravity 1sp of 0.1W1.5. when a film-forming material is applied to the surface and dried, a board having high waterproofness and unique surface patterns is obtained. The mixture of the raw materials of the polyurethane resin foam and the inorganic powder is laminated onto a sheet and subjected to the one-piece foam molding taking advantage of the self-adhesive properties to obtain a board having further improved strength.
