摘要： PROBLEM TO BE SOLVED: To provide a cold storage agent and a cold storage agent pack which can perform cold storage over a long time.
SOLUTION: The cold storage agent comprises 1.0 to 2.5 wt.% sodium sulfate, 0.8 to 2.2 wt.% at least either of sodium chloride and potassium chloride, and the balance of water. The cold storage agent pack is prepared by sealing the cold storage agent and a second nonwoven fabric in a water-impermeable bag made of, e.g., polyethylene, polyvinyl chloride, or nylon, the non water-impermeable bag having a double-ply or two-layer structure, and forming a first nonwoven fabric on the outer surfaces of the top and bottom of the water-impermeable bag.

摘要： PROBLEM TO BE SOLVED: To provide a refrigerant which has a lasting cooling ability and, even when the pack has a hole, does not leak out of the hole. SOLUTION: The refrigerant comprises at least water, salt and a water-absorbing polymer. The mixing ratio of water to the salt is 95-99 pts.wt. of water and 1-5 pts.wt. of the salt, relative to 100 pts.wt. of the sum of water and the salt. The mixing ratio of the water-absorbing polymer is 2.3-4.6 pts.wt. to 100 pts.wt. of water and the salt in aggregate to gelatinize the refrigerant. The salt comprises at least one of sodium chloride, potassium chloride and sodium sulfate. The water-absorbing polymer is sodium polyacrylate with a crosslinked structure. The cooling capacity of the refrigerant is not less than 4 hours at +3°C. As is gelatinized, the refrigerant does not leak out of the pack, even when it has a hole. COPYRIGHT: (C)2008,JPO&INPIT
摘要翻译：要解决的问题：为了提供具有持久冷却能力的制冷剂，并且即使当该包装具有孔时也不会从该孔中泄漏出来。解决方案：制冷剂至少包含水，盐和吸水性聚合物。水与盐的混合比为95-99重量份的水和1-5重量的盐，相对于100重量份水和盐的总和。吸水聚合物的混合比为2.3-4.6重量份到100磅的水和盐，使制冷剂凝胶化。该盐包括氯化钠，氯化钾和硫酸钠中的至少一种。吸水性聚合物是具有交联结构的聚丙烯酸钠。制冷剂的冷却能力在+ 3℃不低于4小时。凝胶化后，制冷剂即使具有孔也不会从包装中泄漏出来。版权所有（C）2008，JPO＆INPIT
