Problems solved by technology

Although this method can quickly refrigerate, because the heat absorbed by the dissolution of ammonium chloride in water is not very large, and the dissolution of barium hydroxide octahydrate in water releases heat, the temperature of refrigeration is not low enough to meet the needs of practical applications.

Abstract

The invention discloses a novel quick-cooling chemical ice bag and a preparation method of the novel quick-cooling chemical ice bag. The novel quick-cooling chemical ice bag is prepared from the following components in parts by weight: 20 to 30 parts of ammonium chloride, 50 to 60 parts of barium hydroxide, 30 to 40 parts of ammonium nitrate, 2 to 6 parts of polyvinyl alcohol, 10 to 20 parts of ferric chloride and 15 to 20 parts of sodium chloride. The preparation method of the novel quick-cooling chemical ice bag comprises the steps of accurately weighing according to the weight ratio of each component, adding the weighed polyvinyl alcohol into the barium hydroxide and stirring, wherein the stirring speed is 150 to 250 r / min, and the temperature can be heated up to be 70 to 80 DEG C; stopping heating after the solution becomes transparent, enabling the solution to be naturally cooled to room temperature, and obtaining solution A; sequentially adding the ammonium chloride, the ammonium nitrate and the ferric chloride in the solution A under a stirring state, and obtaining solution B by uniformly stirring the mixed solution; adding the sodium chloride in the solution B, and sealing and packaging the obtained solution in a bag when the mixed solution is uniformly stirred and becomes transparent. According to the novel quick-cooling chemical ice bag disclosed by the invention, the refrigerating speed is fast, and the refrigerating temperature is low.

Description

technical field [0001] The invention relates to a novel quick-cooling chemical ice pack 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, l...
