[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and examples.
[0021] The invention discloses a preparation method of a far-infrared material, such as figure 1 shown, including the following steps:
[0022] S1: Cool and freeze the base material, and keep it for a period of time t0 after reaching the lowest temperature T0;
[0023] S2: Carry out heating treatment on the frozen substrate, and conduct polarization treatment during the heating process. The heating process is that every time the temperature rises to ΔT, keep it for a period of time t1. The maximum temperature of the heating is T1, and the total time of the heating process is t2, the polarization treatment includes emitting far-infrared light waves with a wavelength range of 4 μm-16 μm to the substrate, and simultaneously transmitting high-frequency e...
