Abstract

PURPOSE: A structural material that is made by impregnating a flexible polyurethane foam with water glass and drying them, thus showing cushioning properties, combustion resistance and smoking resistance to be suitably used as an inexpensive rigid polyurethane foamlike cushioning material for furnitures.
CONSTITUTION: A flexible polyurethane foam is dipped in a solution of water glass in a solvent such as water with a proper viscosity and their temperature is raised to effect the impregnation of the foam with water glass more than 10 times the weight of the foam on the solid basis. Then, they are dried.
