Description

Technical Field

[0001] The present invention relates to the technical field of infrared irradiation sources, and more specifically, to an infrared irradiation source, a preparation method thereof, and an application thereof. Background Art

[0002] Infrared irradiation technology is a technology based on the principle of the interaction between matter and infrared radiation. When the infrared wavelength emitted by the infrared irradiation source is close to the characteristic absorption wavelength of the irradiated substance, a resonance effect will occur, and the irradiated substance will undergo changes such as molecular structure change, chemical bond breakage and recombination. This provides a theoretical basis for the application of infrared irradiation technology in the fields of physiotherapy and health care, air purification, antibacterial, deodorization, and antiviral.

[0003] Among them, the irradiation source is the core component of infrared irradiation technology. The existing irradiation sources mainly have the following problems: (1) The radiation wavelength range of the irradiation source is narrow, and it is difficult to meet the requirements of different specific application fields for broadband radiation; (2) The emissivity of the irradiation source is low and the radiation intensity is insufficient, and it is difficult for the irradiated object to obtain sufficient energy input, resulting in poor irradiation effect. Summary of the Invention

[0004] The present invention provides an infrared irradiation source with a wide radiation wavelength range or a high emissivity.

[0005] Another object of the present invention is to provide a preparation method of the infrared irradiation source.

[0006] Another object of the present invention is to provide an application of the infrared irradiation source in a health instrument.

[0007] Another object of the present invention is to provide an application of the infrared irradiation source in air purification.

[0008] To solve the above technical problems, the technical solution provided by the present invention is:

[0009] An infrared irradiation source, the components of which contain iron oxide, graphene, and epoxy resin, and also contain zirconium oxide and zinc oxide.

[0010] In the irradiation material of the irradiation source of the present invention, zirconium oxide, zinc oxide, iron oxide, and graphene are uniformly dispersed in the epoxy resin matrix in a certain proportion, and have the following technical effects:

[0011] (1) The infrared irradiation source has a wide radiation wavelength range

[0012] In the irradiation source of the present invention, zirconia emits infrared rays in the wavelength range of 20 - 400 μm, zinc oxide emits infrared rays in the wavelength range of 8 - 14 μm, iron oxide emits infrared rays in the wavelength range of 3 - 8 μm, and graphene emits infrared rays in the wavelength range of 5 - 20 μm. At specific ratios of the above components, graphene can form a nanonetwork with zirconia, zinc oxide, and iron oxide, serving as a bridge and regulation center for electron transport, enabling the irradiation source to respond to a relatively wide wavelength range from near-infrared to far-infrared, effectively broadening the emission wavelength range of the entire irradiation source.

[0013] (2) The infrared irradiation source has a high emissivity

[0014] The interaction between the components of the irradiation source of the present invention can improve the emissivity of the irradiation source:

[0015] Zirconia has a stable structure, which can reduce the structural changes of zinc oxide during the irradiation process of the irradiation source, contributing to the more stable electron transition and surface plasmon resonance of zinc oxide. Thus, it cooperates with the phonon propagation and other characteristics of zirconia to further promote the transfer and conversion of energy within the material, improve the generation efficiency of infrared radiation, and thereby increase the emissivity.

[0016] The energy absorbed by iron oxide can be transferred to zirconia in the form of heat transfer, etc., enhancing the phonon vibration of zirconia and promoting phonon propagation. Thereby, it further accelerates the energy transfer within iron oxide, enabling iron oxide to release the absorbed energy in the form of infrared radiation more quickly, improving the overall emissivity of the irradiation source.

[0017] After zinc oxide and iron oxide absorb light of different wavelengths, the generated electron-hole pairs can recombine through charge transfer at the interface to release infrared photons, further increasing the intensity of infrared radiation and improving the emissivity of the irradiation source.

[0018] Using the structure of zirconia as a support, graphene can better exert its advantages in carrier transport and heat conduction. Furthermore, it can quickly transport the carriers generated by zinc oxide and iron oxide to other parts of the irradiation source, and change the surface properties and electronic structure of iron oxide, further optimizing its infrared emission performance and improving the emissivity of the irradiation source.

[0019] The infrared irradiation source of the present invention contains the following components in parts by mass:

[0020] Zirconia 5 - 20 parts;

[0021] Zinc oxide 10 - 25 parts;

[0022] Iron oxide 10 - 25 parts;

[0028] S3. Add the irradiation material to the irradiation source substrate, mix evenly, pour it into a mold, demold after condensation and molding, and obtain an infrared irradiation source;

[0029] The shape of the mold in the present invention is that the inner diameter is 5-10 cm, the height is 2 cm, and there is a perforated column with a diameter of 3 mm in the middle.

[0030] The material of the mold in the present invention is stainless steel.

[0141] The multifunctional infrared irradiator provided by the present invention generates a resonance effect with toxic substances such as formaldehyde, benzene series, and TVOC in a similar wavelength band. The molecular chain structure of organic compounds changes, the molecular structure becomes smaller and the activity increases. The material structure expands to accelerate the redox reaction of toxic gases. The thermal effect promotes the expansion of the material structure, which is conducive to the continuous release of toxic gases, and accelerates the redox reaction of toxic substances such as formaldehyde, benzene series, and TVOC with oxygen to generate water and carbon dioxide. Therefore, it can more effectively remove the toxic substances contained in the material. Since far-infrared can use water molecules as a medium to spread and form an accumulative superposition state in the air, the energy can be continuously retained in a specific space for a quite long time. Therefore, even after the multifunctional infrared irradiator is removed, it can retain the function of removing toxic substances such as formaldehyde, benzene series, and TVOC and antibacterial and antiviral effects for a quite long time.

[0142] As described above, it is only the implementation mode of the present invention, and the patent protection scope is not limited thereby. Those skilled in the art make non-substantive changes or substitutions based on the present invention, and still fall within the patent protection scope.
