In order to verify the cyclical stability of thermos cup, 100 experimental tests (initial water temperature is 95 DEG C) are carried out to the thermos cup that embodiment 17 to 22 obtains.Result shows, the hot water rate of temperature fall in the thermos cup of embodiment 17 to embodiment 20 and temperature retention time, without significant change, show that it has good cyclical stability.For embodiment 17 and 18, supposition is that form phase transformation does not cause adverse effect to aerogel heat-insulating material because the heat filling effect in heat conduction phase change layer high in embodiment 17 to embodiment 18 forms " Gu Gu-"; For embodiment 19 to embodiment 20, supposition avoids the destruction that the liquid state phase change material after phase transformation causes aerogel heat-proof layer.The thermos cup of embodiment 21 and 22 is when second time uses, and temperature retention time foreshortens to 0.5h by 1.5h; When using for the 5th time, it is without obvious insulating process, supposition is because heat filling is less, the pore space structure of liquid to aerogel material produced during the phase transformation of heat conduction phase change layer produces obvious destruction, its heat-proof quality is caused greatly to decline, the temperature retention time showing as thermos cup shortens greatly, reduces Practical Performance.
Embodiment described herein is only to preferred embodiment example of the present utility model explanation.The utility model person of ordinary skill in the field can carry out various amendment according to content disclosed in the utility model to described embodiment, but the technical scheme not departing from essence of the present utility model revised thus and obtain still drops within appended claims limited range.
