the invention can be used in different fields by adding the powder material capable of continuously emitting far infrared rays into different carriers, and particularly, the inventor finds that when the powder material is used for the thermoplastic elastomer, the emission intensity of the far infrared rays of the powder material can be maintained, and the inventor finds that the polyurethane thermoplastic elastomer can increase the loading rate and the coverage rate of the powder material in the elastomer and further enhance the far infrared emissivity of the rare earth material compared with other carriers, the applicant considers that the far infrared emissivity of the rare earth material is further enhanced probably because the selected polyurethane main chain has more NH structures, has better acting force on the powder material and can be adsorbed on more powder raw materials, but the inventor finds that the performance difference of the surfaces of the black tourmaline and the high polymer is larger and is difficult to be stabilized in the polymer material for a long time, after long-time use, the far infrared emission amount of the rare earth material can not be reduced, and the inventor further finds out through experiments that the linear thermoplastic TPU can improve the stability of far infrared emission; the inventor believes that the reason is probably that when linear polyurethane selected under the condition has a certain degree of crosslinking, the rare earth powder material can be fixed in the gap to reduce the mobility of the rare earth powder material, but the linear TPU cannot ensure that the rare earth powder with high load rate can keep better locking effect because the crosslinking degree is lower, and the inventor unexpectedly finds that the specific gravity is selected to be 1.1-1.23g/cm³Meanwhile, when the linear TPU thermoplastic resin with the glass transition temperature of-50 to-15 ℃ is used as a carrier material, the high load rate can be ensuredIn this case, the inventors speculate that the crosslinking space of TPU with this range of glass transition temperature and specific gravity may form a suitable grip on the powder material and a good fixation of the powder, not so tight that the powder is removed, not so loose that the powder is easy to migrate, and reducing the mobility of the thermoplastic elastomer to the powder.

In the experimental process, the inventor finds that when the loading rate of the carrier on the powder material is increased, the performance of the TPU thermoplastic elastomer is influenced, the toughness of the carrier is reduced, the carrier becomes brittle, and the rare earth material is easily scrapped in the use process of the material, so that the use effect of the rare earth material is influenced. However, the inventor unexpectedly finds that the synergistic effect can be generated by adding a certain proportion of hydroxyapatite and rare earth soluble salt for compounding, so that the far infrared emission can be further enhanced, and the toughness of the elastomer carrier can be improved.
