PURPOSE : A composition for compound heat-insulating material is provided to offer thermal ability and various function by including phase change material(PCM), deodorizing/adsorbing agent, antimicrobial agent, and rice bran. CONSTITUTION : A composition for compound heat-insulating material comprises 42-55%% of heptadecane, 1-3%% of acrylic binder, 10-12%% of rice chaff powder, 3-5%% of the ceramic inorganic binder, 1-1.5%% of rapid hardening material, 1%% if antimicrobial agent, 20-25%% of more than one of quartz, vermiculite, tourmaline, rare earth, and illite, 3%% of zeolite powder or liquid, 3-4%% of potassium silicate and/or sodium silicate, 2-3%% of calcium carbonate, and 0.3-0.4%% of cellulose based on 100weight%% of composition. The rice chaff powder has average particle diameter of 1000 mesh. More than one of the quartz, vermiculite, tourmaline, rare earth, and illite are pulverized to 800mesh. The ceramic inorganic binder is loess which is shattered into average particle diameter of 3000 mesh pieces. COPYRIGHT KIPO 2012
