Abstract

PURPOSE: An inorganic powder is mixed with inorganic fibers, viscosity controller and others and foamed to produce rigid foam inexpensively with no use of solvent, which is suitably used as a heat insulation material or fire-proof boards because of its high mechanical strength.
CONSTITUTION: An inorganic powder such as calcium carbonate of 30W200 mesh is mixed with a foaming agent such as ammonium carbonate, a small amount of inorganic fiber such as glass fiber and a liquid thermosetting resin such as unsaturated polyester as a viscosity controller, preferably by 30W300wt% based on the inorganic powder and they are foamed under normal pressure.
