Problems solved by technology

Although this method can effectively reduce the temperature, there is a problem because the chemical composition in the preparation process is relatively simple: the dissolution rate of salt in water is very fast, and the temperature will change rapidly, but there is no supplement to maintain this low temperature. Substances that lead to short refrigeration time

Abstract

The invention discloses a durable chemical ice bag and a preparation method thereof. The durable chemical ice bag is prepared from the following components in part by weight: 60 to 70 parts of ammonium nitrate, 60 to 70 parts of sodium carbonate decahydrate, 20 to 30 parts of aluminum potassium sulfate dodecahydrate, 1 to 4 parts of polyvinyl alcohol, 3 to 7 parts of ethanol and 10 to 20 parts of sodium chloride. The preparation method for the durable chemical ice bag comprises the following steps of weighing the components according to the weight parts; adding the weighed polyvinyl alcohol into the aluminum potassium sulfate dodecahydrate for stirring; heating a mixture to 90 to 100DEG C; when a solution becomes transparent, stopping heating, and naturally cooling the solution to room temperature to obtain a solution A; sequentially adding the ammonium nitrate, the sodium carbonate decahydrate and the ethanol into the solution A by stirring, and uniformly stirring a mixture to obtain a solution B; adding the sodium chloride into the solution B; when the solution is uniformly stirred and becomes transparent, packaging with bags to obtain the durable chemical ice bag. The durable chemical ice bag disclosed by the invention is long in refrigeration time.

Description

technical field [0001] The invention relates to a durable chemical ice bag and a preparation method thereof, belonging to the technical field of chemistry. Background technique [0002] Chemical ice packs are made by using the principle that certain chemical substances (such as ammonium salts) absorb heat during the dissolution process, and the temperature in the bag drops rapidly. It is mainly used in medical care (such as cold compress to reduce swelling), or food preservation, or medicine (such as vaccine) cold storage, etc., and has good results. In short, chemical ice packs play a relatively important role in daily life. [0003] Usually people use ice cubes to realize the purpose of cooling, but use ice cubes to bring great inconvenience, such as ice cubes are solid, the contact area is not large, the cooling is uneven, and it is difficult to achieve the desired effect. Compared with ice cubes, chemical ice packs have the characteristics of small size, light weight, ...
