FIG. 5(a) is a graph showing the operation of the 3cm by 3cm low voltage heating ink packs prepared in example 1 of the present invention at different voltages.And respectively switching on heating data of direct current voltages of 1.0v, 1.5v, 2.0v, 2.5v and 3.0v, and testing the temperature response rate of the low-voltage heating ink block and the saturation temperature of the low-voltage heating ink block at each working voltage. The temperature influence speed is fast, the saturation temperature can be reached by switching on the power supply for about 10s, the required voltage is extremely low, the heating efficiency is high, and the heating rate is fast. When 1.0v of voltage is applied to the low-voltage heating ink block, the passing working current is 0.28A, and the saturation temperature which can be reached is about 47 ℃; when 1.5v voltage is switched on, the passing working current is 0.428A, and the saturation temperature is 70 ℃; when 2.0v of voltage is applied, the working current is 0.583A, and the saturation temperature is 100 ℃; when 2.5v of voltage is applied, the working current is 0.749A, and the saturation temperature is 130 ℃; when 3.0v voltage was applied, the operating current was 0.915A, and the saturation temperature reached by the low voltage heat-generating ink block was about 175 ℃. The prepared low-voltage heating ink block has very high electrothermal radiation conversion efficiency, extremely low required working voltage and safer use of the low-voltage heating ink. Fig. 5(b) shows the operation of the low voltage heating ink block under the condition of continuously changing voltage, the voltage applied to the low voltage heating ink block is continuously increased from 1.0v to 3.0v at intervals of 0.5v, and it can be seen that the response rate and the heating stability are very stable, and the saturation temperature reached at the same voltage is consistent with that of the graph in fig. 5 (a). According to an electrothermal radiation conversion efficiency formula: β ═ S α (T)r 4-T0 4) P, where β is the electrothermal radiation conversion efficiency of the electrothermal film, S is the heating area of the electrothermal film, and α is the Spander-Boltzmann constant (5.67 × 10)-8In the unit of W/m2K4)，TrIs the saturation temperature, T, at a certain operating voltage0P is the ambient temperature and electric power. According to the formula, the electrothermal radiation conversion efficiency beta of the low-voltage heating ink block under the working voltage of 3v is 74.75 percent, which is about 10 percent higher than that of the traditional electrothermal material.
The carbon material is stable in chemical property, can stably exist in the air, is not suitable for reacting with oxygen, the aqueous acrylic resin used by the low-voltage heating ink block is stable and does not decompose in the air below 250 ℃, and the conductive carbon particles are stable and does not decompose in the air below 400 ℃, so that the prepared low-voltage heating ink block can continuously and stably work at the running temperature below 200 ℃. To further verify that the low voltage heat-generating ink block can continuously and stably operate at high temperature (175 ℃), the low voltage heat-generating ink block is modulated to have higher working voltage (3.0v) and is kept for more than 4h in the operation state at 175 ℃. As shown in fig. 6, the temperature-time variation relationship shows that the saturation temperature remains unchanged in the high-temperature state, which indicates that the electrothermal infrared radiation efficiency of the low-voltage heat-generating ink block, and the composition and performance of the ink are not changed, which is sufficient to prove that the stability of the low-voltage heat-generating ink in the air and in the high-temperature state is very outstanding.
Fig. 7 shows a functional relationship between the heating temperature and the power density of the low-voltage heating ink block prepared in this embodiment, and a fitted curve of the temperature and the power density is approximately linear (T ═ 249 × P +37, T is the temperature, and P is the energy density), and as can be seen from the graph, the slope is steep (about 249.53 ℃ c, cm2W-1), which indicates that the saturation temperature that can be reached per unit area under the same power density condition is higher, i.e., the electrothermal infrared radiation efficiency is higher, which indicates that the electrothermal infrared radiation efficiency of the low-voltage heating ink block prepared based on this embodiment is higher, and the energy consumption is lower.
Fig. 8 is a graph of the volt-ampere (V-a) relationship of the low voltage heat-generating ink stick prepared in this example, and it can be seen from the fitted curve that the voltage V applied to the low voltage heat-generating ink stick is almost proportional to the passing current a, indicating that the resistance of the low voltage heat-generating ink stick does not change with the increase of temperature (the saturation temperature is 47 ℃ at 1.0V to 175 ℃ at 3.0V), i.e., the resistance does not change with the change of temperature.
Fig. 9 is a graph of the relationship between the input voltage and the saturation temperature of the low-voltage heat-generating ink stick prepared in this example, and it can be seen from the fitted curve in the graph that the saturation temperature reached when the low-voltage heat-generating ink stick was operated with electricity is exponential to the voltage applied across: t ═ A1exp(-V/t1)-y0Where T is the saturation temperature of the electrothermal film, V is the voltage at which it is switched on, A1＝39.98±13.40，t1＝-1.91±0.31，y0＝-14.84±16.71. The exponential relationship between temperature and voltage shows that the conversion efficiency of the low-voltage heat-generating ink block prepared in the embodiment through infrared heat radiation is high.
The low-voltage heating ink block is placed in a room-temperature air environment, the same voltage of 3.0v is applied to the same low-voltage heating ink block for ten consecutive days, the temperature response rate and the maximum saturation temperature of the low-voltage heating ink block are almost unchanged, the stable operation in the air is shown, and the advantage of the low-voltage heating ink block is obvious compared with some metal electrothermal materials (such as silver electrothermal materials) which are easy to oxidize in the air.
