Abstract
The present invention discloses a snow -feeling regenerative heat, the way of making it and regenerative heat and cold articles including this regenerative heat agent consists of three components : Celluloses derivative or starch flour derivative, sodium salt, and water. The mixture is made of the three components by proportion 3-11 to 2-10 to 40-220, according to the range of weight. It can be used as cooling or warming agents, besides it can be made into regenerative heat and cold articles including regenerative heat agent. The present invention is easily made, conveniently and widely used, and the price is cheap. This regenerative heat agent appears a high molecular gel condition to the room temperature. So it has pretty good capacity to regenerate heat. After cooling it appears a snow-feeling condition, when the temperature is raised up it absorbs more heat than the usual regenerative cold agents, so it is better in keeping cold.
Description
【Technical field】 [0001] The present invention relates to a technology of cold storage and heat storage, in particular, it provides a heat storage agent with a snow texture after freezing and a cold storage heat storage product containing the heat storage agent, which are used in people's life, work, travel or medical treatment. middle. 【Background technique】 [0002] In people's daily life, work, travel, etc., the use of physical methods for cold and heat regulation is becoming more and more widely used. In labor protection, heatstroke prevention and cooling, medical rescue, high fever cooling, anti-inflammatory and pain relief, sprains and injuries, post-operative care, as well as heat storage and cold storage in the transportation of food preservation, ornamental fish, medicines, biochemical reagents, vaccines, etc. It has also been used to save energy. widely used. Especially in medical treatment, it has achieved good results in clinical applications. The working prin...
