PURPOSE: A composite latent material composition and a manufacturing method thereof are provided to have excellent thermal properties and to be used for various purposes cooking. CONSTITUTION: A composite latent material composition comprises a high temperature phase change material which has the phase change temperature of 140-170 deg. Celsius and a low temperature phase change material which has the phase change temperature of 30-60 deg. Celsius. The high temperature phase change material which has the phase change temperature of 140-170 deg. Celsius is one or more sugar alcohol based phase change material selected from xylitol, isomalt, maltitol and mannitol. The low temperature phase change material which has the phase change temperature of 30-60 deg. Celsius is paraffin based phase change material having 18-30 carbons. The mixing ration of high temperature phase change material to the low temperature phase change material is 9 : 1 - 5 : 5. |
