HEAT INSULATING MATERIAL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide a new material which has the heat insulating property comparable to that of urethane foam and in which at least one of the defects of urethane foam is improved. SOLUTION: This heat insulating material composition contains cement, aggregate, a granular body of an expanded organic resin of≥4 parts weight and <40 parts weight on the basis of 100 parts weight cement and an organic binder (excluding a water-soluble macromolecule) of≥1 part weight and≤50 parts weight. The content of the granular body of the expanded organic resin exceeds 5 wt.% of this composition. COPYRIGHT: (C)2004,JPO
