[specific embodiment]
See also shown in Fig. 1 and 2, a kind of insulating bag 1, this insulating bag contains oversaturated sodium acetate aqueous solution and air.The aqueous solution of oversaturated sodium acetate is to make by sodium acetate is dissolved in the water, preferably the cooperation ratio of sodium acetate and water is maintained between 10: 1 and 30: 1 in order to obtain preferably heating effect and to reduce cost of manufacture.Sodium acetate aqueous solution can be a sodium acetate trihydrate solution.
Above-mentioned air is to be provided with for continuing of the heating process of stablizing insulating bag and fever time.In addition, the volume of air is preferably between the 0.01%-5% of insulating bag volume.Certainly, also can use the oxygen replaces air, the volume of aforementioned oxygen is identical with the amount of the oxygen that the injection air comprises.
The overcoat 1 that stability of using for above-mentioned insulating bag 1 and sealing utilization are made by PVC, PP or PU is with sodium acetate aqueous solution and aeroseal.
For the state of temperature of better recognition insulating bag 1, can add the different camouflage paints that change of temperature, thereby can dope the temperature of insulating bag 1 by change color according to insulating bag 1.The weight of camouflage paint is preferably less than 5% of whole insulating bag weight.
Insulating bag 1 is after putting the regular hour after the use in 100 ℃ of boiled water, the crystalline solid of inner solid, shaped can become liquid again, can reuse.
See also shown in Figure 3, the aqueous solution of sodium acetate in 100 ℃ boiled water according to after the dissolving of certain ratio, made the aqueous solution of supersaturated sodium acetate, in airtight overcoat, inject the air of certain volume, under the condition of 25 ℃ of room temperature (temperature error ± 0.01 ℃), time period has been done the temperature test (test error ± 0.01 ℃) of heating, and test data is as shown in Table 1.
Comparative example 1 is the supersaturated sodium acetate solution that same method is made, and after putting into elastomeric vibrations material in the insulating bag, utilizes elastomeric physical impact to cause the crystallization of sodium acetate.
