Description

Technical Field

[0001] This invention belongs to the field of composite material technology, and specifically relates to a passive terahertz fragrance bead and its preparation method; particularly, a technical solution for composite materials to generate terahertz radiation by being excited by human body heat sources. Background Technology

[0002] With changes in modern lifestyles, sub-health issues are becoming increasingly common, particularly eye strain, neck discomfort, lumbar muscle strain, and joint pain, which plague a large population. Terahertz therapy, as a non-invasive physical therapy, is widely used in the health care field due to its safety, comfort, and lack of side effects.

[0003] In existing technologies, terahertz health products are mainly divided into two categories: one is electrically heated products, which generate terahertz radiation through heating resistance wires or carbon fibers, but these have problems such as safety hazards, inconvenience in washing, and high energy consumption; the other is room-temperature terahertz products, which use materials such as tourmaline and ceramic powder to emit terahertz waves at room temperature, but these have shortcomings such as limited emissivity and limited functionality. In recent years, passive terahertz materials have become a research hotspot in the health field, but existing materials still have considerable room for improvement in terms of emissivity and semiconductor characteristic regulation.

[0004] Furthermore, existing traditional Chinese medicine health products are mostly available in the form of medicine packets or powders, which have problems such as uncontrollable drug release, uneven drug distribution, and easy failure. There is limited research on combining passive terahertz materials with traditional Chinese medicine, and a lack of in-depth exploration of the synergistic mechanism between the two.

The composition is based on typical prescriptions selected according to the symptoms, including extracts of effective components of traditional Chinese medicine and / or cell wall-breaking powder of traditional Chinese medicine. The amount of composite ceramic material powder is 30-120% of the total weight of the traditional Chinese medicine composition powder. The two are mixed to form beads.

[0007] The rare earth element in the composite ceramic material includes lanthanum oxide. It also includes 2-4 parts by weight of yttrium oxide. .

This synergistic formula is made of 50 parts Angelica sinensis extract, 50 parts Carthamus tinctorius extract, 50 parts Vaccaria segetalis extract, 50 parts dried ginger powder, 10 parts cinnamon twig powder, 5 parts Asarum sieboldii powder, 5 parts camphor, and 10 parts borneol.

[0009] Furthermore, the extract involved in the traditional Chinese medicine composition refers to the extract powder obtained by extracting 1 part of dried Chinese medicinal materials with water or alcohol.

[0010] Furthermore, it also includes nanmu wood adhesive powder, accounting for 40-60% of the total weight of composite ceramic material powder and traditional Chinese medicine composition powder.

[0011] The method for developing passive terahertz compound fragrance beads includes the preparation of composite ceramic material powder and the production of traditional Chinese medicine composition powder. The preparation steps of the composite ceramic material are as follows: S1 Mixing and Granulation: Nickel oxide, chromium trioxide, iron oxide, cobalt oxide, activated carbon powder, and lanthanum oxide are mixed according to the formula. Anhydrous ethanol and grinding balls are added, and wet ball milling is performed for 8-12 hours. The ball-to-material mass ratio is (2-4):1. The ball-milled slurry is dried at 80-120℃ for 20-30 hours and passed through a 200-mesh sieve to obtain a mixed powder. A polyvinyl alcohol (PVA) aqueous solution accounting for 5-10% of the powder mass is added to the mixed powder as a binder. The mass concentration of the polyvinyl alcohol (PVA) aqueous solution is 8%. After stirring evenly, the mixture is granulated through a 40-mesh sieve. The resulting wet granules are dried at 60-80℃ for 1-2 hours and passed through a 40-mesh sieve again to obtain dry granules with uniform particle size and good flowability. S2 molding: The granulated material is pressed into a green body under a pressure of 150-200MPa; the green body can be directly used in the subsequent sintering process, and if the surface is wet, it is dried at 80℃ for 1-2 hours. S3 sintering: The green body is buried with mixed embedding powder and sintered in two stages under inert gas protection. First, the temperature is raised to 600-800℃ and held for 1-2 hours to remove the binder. Then, the temperature is raised to 1150-1200℃ and held for 2-4 hours to sinter. The composite ceramic material is then cooled in the furnace. S4 Grinding: Powder is obtained by ball milling and passing through a 400-mesh sieve, and is ready for use; The steps for preparing the powdered traditional Chinese medicine composition are as follows: Mix the Chinese herbal extracts and cell wall-breaking powder raw materials in the specified proportions, and pass them through a 200-mesh sieve for later use; Making Incense Beads: Mix the raw materials obtained above with the Nanmu adhesive powder in a certain proportion, add water of 40-60% of the total weight of the powder, knead for 1-3 hours to make the mud, make incense beads with a diameter of 2-5mm, and dry them for 3-5 days at 20-30℃ and 45-65% relative humidity, turning them 1-2 times a day to obtain the Chinese medicine incense beads.

[0012] Step S3 includes the following steps: S3-1 Pre-treatment of the green body: The formed green body is placed in a graphite crucible and completely buried with a mixed embedding powder; the mixed embedding powder is carbon powder and silicon dioxide in a mass ratio of 1:1. Powder, or a 1:1 mass ratio of toner to silicon carbide Powder; Carbon powder provides a reducing atmosphere. Silica or silicon carbide is chemically stable and does not react significantly with carbon powder at 1150-1200℃, thus avoiding changes in the composition of the embedded powder or contamination of the sample due to the formation of SiC. S3-2 Atmosphere Replacement: Place the crucible in an atmosphere sintering furnace, first evacuate to below -0.1MPa, then fill with high-purity inert gas to atmospheric pressure, repeat the replacement 2-3 times to remove all oxygen; S3-3 First stage sintering: Increase the temperature to 600-800℃ at 3-5℃ / min, hold for 1-2 hours, and complete the low-temperature removal of the binder; S3-4 Second stage sintering: Continue to raise the temperature to 1150-1200℃ at a rate of 3-5℃ / min, and hold for 2-4 hours; maintain an inert gas flow rate of 2-5L / min throughout the process to ensure a positive pressure protective environment inside the furnace and achieve high-temperature activation sintering; S3-5 Cooling: After the heat preservation is completed, maintain the atmosphere protection and allow the furnace to cool naturally to room temperature. Remove the furnace to obtain the passive terahertz high emissivity composite ceramic material.

[0013] The inert gas is high-purity argon or high-purity nitrogen, with a purity ≥ 99.99%.

[0014] Compared with existing technologies, this invention has the following beneficial effects: The material of this invention is a typical passive terahertz material. During operation, it requires no external power supply and relies solely on the thermal excitation generated by contact with the human body's temperature to achieve efficient terahertz radiation through physical mechanisms such as phonon polaritons and free carrier absorption, thus achieving zero-power health intervention. The traditional Chinese medicine formula of this invention combines extracts with cell-wall-broken powder, with cassia seed, buddleja flower, and dendrobium as the principal herbs, wolfberry and Hangzhou white chrysanthemum as the assistant herbs, and borneol as the adjuvant herbs, conforming to the traditional Chinese medicine theory of "clearing the liver and improving eyesight, promoting blood circulation and unblocking the meridians." The use of extracts increases the concentration of effective ingredients, and the cell-wall-broken powder technology enhances bioavailability.

[0015] This invention employs a ternary compound system of "traditional Chinese medicine powder + functional material powder + adhesive" and integrates it with the "awakening mud" process. The resulting incense beads possess the ability to release drugs slowly and sustainably, achieving a synergistic effect between passive terahertz therapy and traditional Chinese medicine aromatherapy. It can be widely used in health care products such as eye masks, pillows, neck supports, waist supports, and knee supports. Detailed Implementation

[0023] Step 4: Molding: Press the granules into round blanks with a diameter of 30mm and a thickness of 3mm under a pressure of 200MPa.

[0024] Step 5: Sintering (1) Pre-treatment of embedding powder: The blank is placed in a graphite crucible and completely embedded with mixed embedding powder (carbon powder: silicon powder = 1:1).

[0025] (2) Atmosphere replacement: Place the crucible in the atmosphere sintering furnace, evacuate to -0.095MPa, fill with high-purity argon to atmospheric pressure, and repeat 3 times.

[0026] (3) First stage sintering: Heat to 600℃ at 5℃ / min, hold for 1 hour, and complete the glue removal.

[0027] (4) Second stage sintering: The temperature is increased to 1150℃ at 4℃ / min and held for 3 hours. The argon flow rate is 3L / min throughout the process.

[0028] (5) Cooling: After the heat preservation is completed, the furnace is cooled to room temperature to obtain composite ceramic material sample S1.

[0029] Example 2: Preparation of passive terahertz composite ceramic material (silicon content 15%) The experiment was essentially the same as in Example 1, except that the amount of single-crystal silicon powder was adjusted to 15g, nickel oxide to 18g, chromium trioxide to 23g, and kaolin to 4g. The sintering temperature was maintained at 1150℃. Sample S2 was obtained.

[0030] Example 3: Preparation of passive terahertz composite ceramic materials (sintering at 1200℃) The process was essentially the same as in Example 1, except that the sintering temperature was adjusted to 1200℃. Sample S3 was obtained.

[0031] Example 4: Preparation of passive terahertz composite ceramic materials (composite rare earth) The experiment was essentially the same as in Example 1, except that the amount of lanthanum oxide was adjusted to 3g, and 3g of yttrium oxide and 4g of kaolin were added. Sample S4 was obtained.

[0032] Comparative Example 1 (Basic spinel formulation, without Si or rare earth elements) The experiment was essentially the same as in Example 1, except that no single-crystal silicon powder, activated carbon powder, or lanthanum oxide were added. Instead, only 25g of nickel oxide, 30g of chromium trioxide, 15g of titanium dioxide, 10g of iron oxide, 5g of cobalt oxide, and 5g of kaolin were used. The sintering temperature was 1150℃. Sample D1 was obtained.

[0035] III. Ceramic Material Performance Testing The above samples were subjected to performance tests, and the results are shown in Table 1.

[0036] Table 1: Performance test results of different ceramic materials

[0037] Results analysis: 1. Emissivity: The emissivity of samples S1-S4 of this invention is ≥0.94, of which S1 (0.96) and S4 (0.97) are significantly higher than that of basic spinel D1 (0.85) and SiC system D3 (0.90).

[0038] 2. Semiconductor characteristics: The resistivity of samples S1-S4 is between 10¹ and 10³ Ω·cm, and the carrier concentration is 10¹ 6 ~10¹ 8 / cm³, proving that single-crystal silicon successfully retains its semiconductor properties. D2 loses its semiconductor properties due to oxidation of silicon obtained through air sintering.

[0039] 3. Temperature effect: S3 (1200℃) contains a small amount of SiC, and the emissivity decreases slightly. 1150℃ is preferred.

[0040] 4. Rare earth composite: The emissivity of S4(La+Y) is increased to 0.97, which is better than that of single La doping.

[0085] Example 11: Preparation of Traditional Chinese Medicine Incense Beads (with different amounts of light wave materials) The method is basically the same as in Example 5, except that: 12.0g of light-wave ceramic powder (accounting for 60% of the total weight of the Chinese medicine composition powder) and 16.0g of Indonesian nanmu adhesive powder (accounting for 50% of the total weight of the Chinese medicine powder and light-wave material) are added, along with 24.0g of water (50% of the total powder mass). Sample H2 is obtained.

[0086] Comparative Example 4: Incense beads without ceramic materials The experiment was essentially the same as in Example 5, except that the light-wave ceramic powder was not added. Instead, 20.0g of the traditional Chinese medicine composition powder and 12.0g of Indonesian nanmu adhesive powder were used, along with 16.0g of water (50% of the total powder mass). Sample H3 was obtained.

[0087] Comparative Example 5: Direct Powder Filling Take 20.0g of the traditional Chinese medicine composition powder from Example 5, do not make it into pills, and use it directly as a filler, which is recorded as sample H4.

[0088] V. Performance Testing of Incense Beads 1. Physical performance testing The physical properties of the incense beads H1 prepared in Example 5 were tested, and the results are shown in Table 3.

[0089] Table 3: Physical Properties of Incense Beads

[0090] 2. Volatile oil release performance test Equal masses (10g) of samples H1, H2, H3, and H4 were placed in a sealed container at 37°C and 50% relative humidity. The cumulative release of volatile oil (based on borneol) was measured over 24 hours.

[0091] Table 4: Comparison of volatile oil release from different samples over 24 hours

[0092] Results analysis: The release of volatile oil from the incense beads containing light-emitting materials (H1) was higher than that from those without (H3), demonstrating that the terahertz thermal effect of the light-emitting materials can significantly promote the release of volatile components from traditional Chinese medicine. The release further increased with increasing light-emitting material content (H1→H2), indicating a dose-response relationship.

[0093] While direct powder filling (H4) yields the highest release, it releases too quickly (58% of the 24-hour release is achieved in the first 4 hours), resulting in a short duration of efficacy and poor release uniformity (CV=42.7%). In contrast, the compound fragrance beads of this invention release stably with the best release uniformity (CV=18.5%), exhibiting a sustained-release effect.
