Abstract

상분리 및 과냉각 현상이 없는 냉난방용 잠열 축열재가 제공된다. 이 축열재는 난방용의 경우 이미 가교 반응이 완료되어 다량의 수분을 흡수할 수 있는 고흡수성 고분자를 조핵제와 함께 망초에 직접 혼합시키고, 냉방용의 경우 상기의 난방용 축열재에 추가로 상전이 온도를 망초의 상전이 온도 이하로 낮추어줄 수 있는 빙점 강하제를 첨가시킨 것이다.Provided is a latent heat storage material for heating and cooling, which is free from phase separation and subcooling. This heat storage material is a mixture of superabsorbent polymers that can absorb a large amount of water and complete the crosslinking reaction for heating, and directly mixed with nucleating agent to the forget-me-not, and in case of cooling, the phase transition temperature is added to the heating heat storage material for heating. It is the addition of a freezing point depressant that can lower the phase transition temperature below.
