ENERGY STORAGE BUILDING MATERIALS USING PHASE CHANGE MATERIAL IN MICROCAPSULE AND THE METHOD FOR MANUFACTURING THEREOF

摘要

Provided are an encapsulated fine particle for a heat storage building material, and a highly functional heat storage building material prepared by using the encapsulated fine particle which maintains the temperature of a room to be constant to reduce the cooling or heating cost. The encapsulated fine particle comprises 70-90 wt% of a paraffin-based material as a phase transition liquid latent heat material; and a melamine-based resin which encapsulates the paraffin-based material. Preferably the paraffin-based material is selected from the group consisting of hexadecane (m.p. 18.1 deg.C), heptadecane (m.p. 21.9 deg.C) and octadecane (m.p. 28.1 deg.C). The heat storage building material is prepared by mixing the encapsulated fine particle with a polymer resin.
