Paper Title:
Preparation and Properties of Sepiolite Thermal Storage Composites
  Abstract

Natural sepiolite composites and selected sepiolite composites were prepared in liquid phase by intercalation, and the properties of composites were characterized by test analysis of TG/ DTA, SEM, XRD. Results show that a wide range of endothermic peak is between 30.0~ 40.0°C, their advisable scope of phase change temperature is 3.81°Cand 4.4°C respectively.LA-SA content in two kinds of sepiolite composites attain 42.3 wt% under the best component condition, their modified temperature is 80°C and room temperature respectively. The weight loss of the composites is no more than 2.0 wt% among phase change temperature. Two kinds of modified sepiolite as carrier have little effect on properties of composites, LA-SA content does more. A large amount of LA-SA is adsorbed effectivelly into internal pores or surfaces of modified sepiolite. In view of cost and resource,natural sepiolite has advantages over selected one. This research provides prospective applicaiton foundation for energy-saving building thermal storage composites.
