Abstract

무기염류의 결정물, 또는, 재결정물이 실온근방에서의 온도상승에 의해 용매인 물에 용해되어 가는 때에 생기는 흡열을 이용한 냉열제이며, ① 인산나트륨염류와, ② 인산암모늄나트륨, 또는 인산암모늄염류와, ③ 물과를 혼합해서된 냉열제이다.
본 발명의 냉열제는 인산나트륨계 염류와 인산암모늄계의 염류와를 병용한 것이며, 종래의 기술의 결점이 있든 결정의 결정의 괴상화가 방지되고, 다수회의 반복시용이 가능하게 되었다.
또, 결정핵 형성제나 고분자보수제 증점제등을 첨가한 경우에는 다시 또 미세하고, 안정된 결정석출상태가 유지되도록 되였다.
따라서, 본 냉열제를 청량베개등에 응용하므로서 우수한 냉각성능을 보유함과 동시에 부드럽고 감촉이 양호하고, 쾌적 또한 안전하고, 더구나 장시간 방치해도 결정이 괴상화 하는 일이 없고 항상 안심하고 반복사용하는 것이 가능해 졌다.
