LATENT HEAT ACCUMULATION MATERIAL COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a latent heat accumulation material composition capable of suppressing the supercooling in coagulation without lowering the proper freezing point (57-58 deg.C and the latent heat accumulation of sodium acetate. SOLUTION: This latent heat accumulation material composition is composed mainly of sodium acetate and contains water at a weight ratio [sodium acetate (in terms of anhydrous state):water (including crystallization water contained in the system)] of 55:45 to 68:32. The composition further contains 0.1-3 pts.wt. of one or more kinds of >=14C straight-chain saturated fatty acid alkali metal salts based on 100 pts.wt. of the sum of sodium acetate and water.
