Description

Preparation and application of a magnetic silica gel health care material Technical Field

[0001] The present invention relates to the technical field of health care, and in particular to the preparation and application of a magnetic silica gel health care material. Background Art

[0002] Magnetic therapy is a method of treating diseases by applying magnetic fields to the human body. Magnetic fields can affect the distribution of electrical currents, the movement of charged particles, the permeability of the sarcolemmal system, and the magnetic moment orientation of biopolymers. This can alter the physiological and biochemical processes of tissue cells, resulting in analgesic effects, swelling reduction, and improved blood and lymphatic circulation. Magnetic therapy can be used to treat a variety of conditions. For example, it can improve blood circulation in the hair follicles below the head, ensuring adequate blood supply to the dermal papilla. This significantly increases nutrition and melanin granules in the medulla and cortex, enhancing cell activity and division, promoting hair darkening, and effectively treating hair loss. Magnetic therapy can affect charged particles in the blood, changing their speed and direction of movement. This in turn increases blood flow, improves blood supply to the affected area, and improves circulation, thereby reducing inflammation and promoting tissue repair. It has a significant therapeutic effect on conditions such as prostatitis. In addition, the magnetic field can expand the cardiovascular system, improve blood circulation, increase the heart's oxygen supply capacity, enhance nutritional status, increase the volume of red blood cells, increase oxygen carrying capacity, promote metabolism, remove accumulated free radicals in the body, and have anti-aging effects. Not only that, it also has a certain sedative effect, eliminating insomnia and mental stress problems, and other health care functions.

[0003] At present, achieving health care goals through magnetic therapy products has become a common way. Silicone magnetic therapy products are mostly made of silicone material as the main material, releasing a magnetic field of a certain intensity, but the magnetic field intensity is small, the magnetic therapy effect is poor, the treatment effect is not specific, and the magnetic field is prone to decrease or disappearance when the magnetic therapy product is exposed to other magnetic fields. In addition, common silicone products may cause skin discomfort after long-term contact. Therefore, how to develop a magnetic silicone health care material with strong magnetic field force, multiple effects synergistically enhancing the magnetic therapy effect, and targeted multiple treatment effects, long service life, and good skin affinity is a technical problem that needs to be solved urgently.

[0004] Summary of the Invention

[0005] In response to the above technical problems, the present invention proposes the preparation and application of a magnetic silicone health care material. The magnetic silicone health care material comprises, from the inside out, a magnetic conductive layer, a silicone magnetic material layer, and a magnetic field shielding layer. The silicone magnetic material layer can generate a stable and long-lasting magnetic field force, and the synergistic effects of various effects such as drugs and heating enhance the effect, resulting in good magnetic therapy and health care effects, which are beneficial to human health and have good skin affinity. The magnetic conductive layer can strengthen the magnetic field at the distribution of acupuncture points, further improving the therapeutic and health care effects. The magnetic field shielding layer can prevent the external magnetic field from weakening or eliminating the magnetism of the magnetic material, greatly extending the service life of the magnetic silicone health care material. The prepared magnetic silicone health care material can be used in targeted applications to treat hair loss, low back pain, prostate disease, etc.

[0006] The present invention is achieved through the following technical solutions:

[0010] Furthermore, the method for preparing the magnetic material comprises the following steps:

[0011] (1) Add the rare earth material into a vacuum melting and rapid solidification furnace and evacuate the vacuum to 20 Pa;

[0012] (2) When the temperature rises to 200°C, continue to evacuate to 5 Pa and fill with helium;

[0013] (3) When the temperature rises to 1600°C, adjust the speed of the water-cooled copper roller to 50 rpm, control the inlet water temperature at 12-14°C, take out the rapidly solidified rare earth quick-setting sheet and send it into a cooling tank, and cool it for 3-4 hours to obtain a rare earth alloy sheet;

[0014] (4) The rare earth alloy flakes obtained in step (3) and the ferroferric oxide powder were mixed in a mass ratio of 2:1, and ball milled for 15 hours to form a powder with a particle diameter D50 of 120-150 nm to obtain a magnetic material.

[0015] Furthermore, the rare earth material in step (1) includes the following raw materials in parts by mass: 40-60 parts of neodymium, 2-15 parts of dysprosium, 2-12 parts of lanthanum, 10-30 parts of boron, 0.1-2 parts of aluminum, and 0.1-1 parts of copper.

[0016] Furthermore, the preparation method of the microporous silica gel comprises the following steps:

[0017] i tetramethyltetravinylcyclotetrasiloxane and octamethylcyclotetrasiloxane were mixed in a mass ratio of 4-7: 3-5 to obtain a mixed solution I;

[0018] ii. Sodium hydroxide was added to the mixed solution obtained in step i I as a catalyst, the amount of sodium hydroxide was 0.1-0.15% by mass of the mixed solution I, after thorough mixing, vacuum drying to remove water, gradually heating to 90-110 ℃, reacting 10-15h to obtain a mixed solution II;

[0019] iii. Add 0.3-1% by mass of the capping agent decamethyltetrasiloxane to the mixture II, and remove small molecules in vacuo after 15-20h to obtain polymethylvinylsiloxane;

[0020] iv. Add isopentane to polymethylvinylsiloxane at a mass ratio of 2:1 at 20-25°C, mix well, and heat to 30-35°C to obtain microporous silica gel.

[0021] Furthermore, the Chinese herbal medicine is one or more of cinnamon twig, kudzu root, dried ginger, codonopsis pilosula, and pollen cattail.

[0022] Furthermore, the magnetic shielding coating layer is made of the following raw materials in parts by weight: 25-30 parts of water-based resin, 4-6 parts of methyl cellosolve, 3-5 parts of ethylene glycol butyl ether acetate, 2-4 parts of polyethylene glycol, 28-35 parts of magnetic shielding filler, and 15-20 parts of water.

[0024] Furthermore, the magnetic shielding filler is graphite powder with a particle size of 10-15 μm.

[0025] The present invention also proposes a method for preparing a magnetic silica gel health-care material, comprising the following steps:

[0026] S1. Ferrous sulfate, ferric chloride, and distilled water were thoroughly mixed in a mass ratio of 3:4:250 to form a solution. The hydrogel-graphene composite material was added to the solution and stirred for 24 hours. After that, the solution was placed in pure water with an equal volume of distilled water. A 1 mol / L sodium hydroxide solution was added to the solution at a volume ratio of pure water to sodium hydroxide solution of 25:1 and stirred for 6 hours to convert the iron ions into ferroferric oxide nanoparticles to prepare a magnetic conductive layer.

[0027] S2. After the magnetic material, iron silicide, graphene and calamine were mixed and ball-milled for 2-3h, they were added to microporous silica gel, stirred evenly, poured into a mold, and heated and cured. After demoulding, a silica gel sheet was obtained, and Chinese medicine and water were mixed in a mass ratio of 1:5, boiled and filtered to obtain a filtrate, and after cooling to room temperature, the silica gel sheet was immersed in the filtrate for 20-24h and then the surface was cleaned and dried to obtain a silica gel magnetic layer;

[0028] S3. The water-based resin, polyethylene glycol, magnetic shielding filler, water were mixed, and after grinding, methyl cellosolve and ethylene glycol butyl ether acetate were added to prepare a magnetic shielding coating layer;

[0029] S4. Bond and coat the magnetic conductive layer, silicone material layer, and magnetic shielding coating layer in the order from inside to outside. The coating amount of the magnetic shielding coating layer is 0.5g / cm 2 , that is, a magnetic silica gel health-care material of the present invention is obtained.

[0030] The invention also proposes the application of magnetic silica gel health care materials, which can be used in the field of health care magnetic therapy.

[0031] Furthermore, the magnetic silicone health care material is applied to products such as hats, underwear, knee pads, and waist protectors to treat diseases such as hair loss, gray hair, prostatitis, leg pain, and back pain, which is beneficial to human health.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention performs high-temperature calcination on rare earth materials to change the crystal structure and microstructure of the rare earth materials, causing the crystal structure to undergo a phase change, thereby improving the magnetic properties and increasing the magnetic energy product. The material can be used as a permanent magnet material. Ferroferric oxide is also a permanent magnet material with strong magnetism. It works synergistically with rare earth materials to generate a strong magnetic field, which can accelerate blood circulation, have a health-care effect, and can also effectively relieve pain and treat diseases such as hair loss, white hair, and prostate problems.

[0034] (2) The present invention prepares silica gel containing micropores. On the one hand, it has a large specific surface area and can adsorb the effective ingredients of drugs, thereby improving the health care function and therapeutic effect of magnetic silica gel materials. At the same time, it plays a sustained release role, preventing drugs from accumulating on the surface of the skin and being unable to be absorbed by the human body. On the other hand, it can increase air permeability and reduce the discomfort of human skin.

[0035] (3) The present invention adds Chinese medicine extracts to improve the therapeutic and health care effects of the magnetic silica gel health care material. The Chinese medicine can be selected according to the treatment purpose to enhance specificity. The magnetic field generated by the magnetic material can promote the body's absorption of the medicine and better exert the efficacy of the medicine. The synergistic effect of the two can significantly enhance the therapeutic effect. The present invention also adds calamine, which is a natural zinc carbonate. It has a protective effect on the skin and can effectively inhibit bacteria, which can avoid allergies and discomfort that may be caused by skin contact with silica gel materials.

[0036] (4) The present invention adds iron silicide, which has a low specific heat capacity. When it absorbs the same amount of heat, the temperature rises higher. When the magnetic silicone health care material rubs against the human body and generates heat, the temperature difference between the iron silicide and the human body increases, which can enhance the therapeutic effect of the magnetic field. At the same time, the temperature increase will further increase the blood circulation speed, promote the absorption of the active ingredients of the drug, relieve muscle tension, reduce spasms and pain, and the three effects of temperature increase, magnetic field, and Chinese herbal medicine promote each other synergistically, making the therapeutic health care effect of the magnetic silicone health care material more prominent. The present invention adds graphene, which is a material with high thermal conductivity and low specific heat capacity. It can quickly transfer heat, further increase the temperature of the magnetic silicone health care material, and improve the therapeutic health care effect. The heating process does not require heating by external force such as charging, which is more energy-saving and convenient.

[0037] (5) The magnetic conductive layer of the present invention is composed of a hydrogel-graphene composite material. The hydrogel-graphene composite material is a cylinder with a diameter of 3 cm. It is added to an iron solution to absorb iron ions and convert the adsorbed iron ions into ferroferric oxide nanoparticles. The obtained material has good magnetic conductivity. It is arranged according to the position of the human acupuncture points and bonded to the side of the silicone magnetic material layer close to the human body. It can specifically strengthen the magnetic field strength at the acupuncture points and enhance the health care effect.

[0038] (6) The magnetic field shielding layer of the present invention is composed of a resin, a diluent, a dispersant, a reinforcing agent, and a magnetic shielding filler. The resin has adhesive properties, the diluent and the additive are used to reduce the viscosity of the resin and to wet the filler, the dispersant can fully disperse the conductive filler, and the reinforcing agent can increase the adhesion between the magnetic field shielding layer and the silica gel magnetic layer. The conductive filler is graphite powder, which has good dispersibility, low price, and poor conductivity, making it an ideal magnetic shielding material. The magnetic field shielding layer can be coated on the outside of the silica gel magnetic layer to prevent the silica gel magnetic layer from being weakened or disappearing when the magnetic field is exposed to a stronger magnetic field for a long time, thereby affecting the health care effect.

[0039] (7) The magnetic silica gel health care material obtained by the present invention has good health care effects and can be specifically applied to the treatment of various diseases as needed, such as hair loss, white hair, pain, prostatitis, etc. BRIEF DESCRIPTION OF THE DRAWINGS
