SOUNDPROOF HEAT INSULATING MATERIAL AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a soundproof heat insulating material low in cost and capable of preventing the scattering of a fiber fine powder generated by the thermal deterioration of inorganic fibers or the like being the main component of a base material layer while holding soundproof properties. SOLUTION: An aqueous dispersion of a scaly ore is applied to the surface of a base material comprising heat-resistant fibers such as inorganic fibers or the like by a brush, a spray system, a roll coater, a dipping system, a shower system or the like and the coated base material is dried to form a scaly ore coating layer.
