[0002] In the field of hairdressing, the performance and safety of hairdressing equipment have always been the focus of attention. There are many problems with the heating structure of traditional hairdressing equipment, such as uneven heating that causes hair damage, too high or too low temperature that affects the hairdressing effect, and the rough surface of the heating structure that is easy to damage the hair. In order to improve these problems, new low-temperature ceramic heating structures have gradually attracted attention; however, the existing low-temperature ceramic heating structure preparation process still needs to be improved; some processes are difficult to accurately control the shape and thickness of the heating structure, resulting in poor contact with the hair; some processes are not optimized in material selection and ratio, which affects the performance and stability of the heating structure; and some processes fail to fully consider surface treatment and temperature uniformity, resulting in insufficient protection of the hair during the hairdressing process.

[0003] In addition, as people's requirements for hairdressing quality increase, the heating structure is not only required to provide a stable and appropriate temperature, but also required to be able to directly contact the hair without causing damage, and at the same time have good hair care functions; therefore, developing a preparation process for a hair-friendly low-temperature ceramic heating structure used in hairdressing instruments, which can accurately control structural parameters, optimize material ratios, perform fine surface treatment and ensure temperature uniformity, has become a key technical issue to meet market demand and enhance the hairdressing experience. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0005] The preparation process of the hair-friendly low-temperature ceramic heating structure used in hairdressing equipment includes the following steps: Step 1, prepare materials. The materials for making low-temperature ceramic heating structures include nano-grade ceramic powder, organic salt low-temperature sintering aids and organic cross-linking agents. Step 2: Modeling of low-temperature ceramic heating structure. Through modeling software, the ceramic heating structure is set to a thin sheet with a thickness between 0.5mm and 5mm. Tiny arc grooves and textures are designed on the surface of the ceramic heating structure. The groove width is 0.1mm-0.3mm, the groove depth is 0.05mm-0.15mm, and the texture spacing is 0.2mm-0.5mm. Step 3, chemically modifying the surface of the nano-ceramic powder by introducing functional groups that can enhance the binding force with the organic salt low-temperature sintering aid and the organic cross-linking agent through chemical vapor deposition or chemical solution impregnation; Step 4, slurry preparation, the nano-ceramic powder treated in step 3, the organic salt low-temperature sintering aid and the organic cross-linking agent are mixed in the following proportions, the mass of the nano-ceramic powder accounts for 40%-60%, the amount of the organic salt low-temperature sintering aid added is 5%-15% of the mass of the nano-ceramic powder, and the mass of the organic cross-linking agent accounts for 25%-45%, and a high-speed stirring device is used to stir at 1000-3000 rpm for 30-60 minutes to form a uniform slurry; Step 5, molding, according to the low-temperature ceramic heating structure modeling in step 2, setting a corresponding mold, and forming the slurry prepared in step 4 into a desired sheet-like structure through the mold; Step 6, low temperature sintering, placing the formed structure into a low temperature sintering furnace, controlling the sintering temperature at 150°C-250°C, and the sintering time at 60-120 minutes, so that the low temperature ceramic structure reaches a certain strength and stability; Step 7, surface treatment, after sintering, use fine sandpaper or grinding equipment to grind the surface, and then polish it to make the surface roughness reach less than 0.1 micron; Step 8, performance testing, conducts a temperature uniformity test on the prepared low-temperature ceramic heating structure to ensure that within the operating temperature range, the surface temperature difference does not exceed 5 degrees Celsius, thereby making a hair-friendly low-temperature ceramic heating structure.

[0006] Preferably, the particle size of the nano-scale ceramic powder is in the range of 1 nm to 100 nm.

[0007] Preferably, the organic salt low-temperature sintering aid is a citrate material or an oxalate material.

[0008] Preferably, the organic cross-linking agent is a modified silicone rubber material or a modified polyester material.

[0009] Preferably, the functional group is a methyl group or a vinyl group.

[0010] Preferably, the heating rate of the low temperature sintering furnace is controlled at 5° C. / min-15° C. / min.

[0011] Preferably, after the surface treatment, a hair care coating containing hair care ingredients is coated on the surface of the low-temperature ceramic structure, the hair care ingredients are serine or squalane, and the mass proportion of the hair care ingredients in the coating is 10%-30%, and the thickness of the hair care coating is 5μm-20μm.

[0012] Compared with the prior art, the present invention has the following beneficial effects: Compared with traditional high-temperature sintering, the low-temperature sintering process greatly reduces energy consumption, helps reduce energy costs in the production process, and is more in line with energy-saving and environmental protection requirements. Shorter sintering time and relatively low temperature help speed up the production process, improve production efficiency, and meet market demand more quickly. The lower operating temperature reduces safety risks during operation and reduces accidents and hidden dangers that may be caused by high temperatures. Low-temperature sintering does not require expensive high-temperature equipment and complex high-temperature resistant facilities, reducing equipment investment and maintenance costs; at the same time, lower temperature requirements also reduce the demand for special heat-resistant materials, further reducing raw material costs, and low-temperature sintering helps maintain the microstructure and properties of nano-ceramic powders, making them perform better in terms of heating uniformity, stability and service life.
