Description

Technical Field

[0001] The 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 human current, the movement of charged particles, the permeability of the sarcolemmal system, and the magnetic moment orientation of biopolymers, etc., so that the physiological and biochemical processes of tissue cells change, producing analgesia, swelling, and promoting blood and lymphatic circulation. Magnetic therapy can be used for a variety of diseases. For example, magnetic therapy can improve the blood circulation of the lower ends of the hair follicles on the head, so that the hair papilla can get sufficient blood supply, thereby significantly increasing the nutrition and melanin particles of the medulla and cortex of the hair, enhancing cell activity, and accelerating division, which is conducive to darkening hair and effectively treating hair loss. Magnetic therapy can affect the charged particles in the blood, change their movement speed and direction in the blood, and then increase the blood flow rate, improve the blood supply to the local lesion, improve the blood circulation in the local lesion, thereby reducing inflammation and promoting tissue repair, and has a good therapeutic effect on diseases such as prostatitis. In addition, the magnetic field can dilate the cardiovascular system, improve blood circulation, increase the heart's oxygen supply capacity, strengthen 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 tension problems, and other health 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. Summary of the invention

[0004] In view of the above technical problems, the present invention proposes a preparation and application of a magnetic silicone health-care material. The magnetic silicone health-care material is composed of a magnetic conductive layer, a silicone magnetic material layer and a magnetic field shielding layer from the inside to the outside. The silicone magnetic material layer can generate a stable and lasting magnetic field force, and multiple effects such as drugs and heating can work together to enhance the effect. It has a good magnetic therapy health-care effect, is beneficial to human health, and has good skin affinity. The magnetic conductive layer can strengthen the magnetic field at the distribution of acupuncture points, further improving the therapeutic health-care effect. 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 a targeted manner to treat hair loss, low back pain, prostate disease, etc.

[0008] Furthermore, the method for preparing the magnetic material comprises the following steps: (1) Add rare earth materials into a vacuum melting and rapid solidification furnace and evacuate the vacuum to 20 Pa; (2) When the temperature rises to 200°C, continue to evacuate to 5 Pa and fill with helium; (3) When the temperature rises to 1600°C, the speed of the water-cooled copper roller is adjusted to 50 rpm, the inlet water temperature is controlled at 12-14°C, the rapidly solidified rare earth quick-solidified sheet is taken out and sent to a cooling tank, and the rare earth alloy sheet is obtained after cooling for 3-4 hours; (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 obtain a powder with a particle diameter D50 of 120-150 nm to obtain a magnetic material.

[0009] Furthermore, the rare earth material in step (1) includes the following raw materials in parts by weight: 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.

[0010] Furthermore, the preparation method of the microporous silica gel comprises the following steps: i The tetramethyltetravinylcyclotetrasiloxane and octamethylcyclotetrasiloxane according to a mass ratio of 4-7: 3-5 was mixed to obtain a mixed solution I; ii. To the mixed solution I obtained in step i, sodium hydroxide is added as a catalyst, the amount of sodium hydroxide is 0.1-0.15% by mass of the mixed solution I, after being thoroughly mixed, vacuum dried to remove water, gradually heated to 90-110 ° C, reacted for 10-15 h, to obtain a mixed solution II; iii. Add 0.3-1% of the mass of the capping agent decamethyltetrasiloxane to the mixed solution II, and remove small molecules in vacuo after 15-20 h to obtain polymethylvinylsiloxane; iv. adding isopentane to polymethylvinylsiloxane at a mass ratio of 2:1 at 20-25 ° C, mixing well and heating to 30-35 ° C to obtain microporous silica gel.

[0011] Furthermore, the Chinese herbal medicine is one or more of cinnamon twig, kudzu root, dried ginger, codonopsis pilosula, and pollen pollen.

[0012] 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.

[0014] Furthermore, the magnetic shielding filler is graphite powder with a particle size of 10-15 μm.

[0015] The present invention also proposes a method for preparing a magnetic silica gel health-care material, comprising the following steps: S1. Ferrous sulfate, ferric chloride and distilled water were mixed thoroughly in a mass ratio of 3:4:250 to prepare a solution, the hydrogel-graphene composite material was added to the solution, stirred for 24 hours, and then placed in pure water with an equal volume to the distilled water, and a 1 mol / L sodium hydroxide solution was added in a ratio of pure water to sodium hydroxide solution of 25:1 by volume, and stirred for 6 hours to convert iron ions into ferroferric oxide nanoparticles to prepare a magnetic conductive layer; S2. After the magnetic material, iron silicide, graphene and calamine are mixed and ball-milled for 2-3 hours, the mixture is added to microporous silica gel, stirred evenly, poured into a mold, heated and cured, and demolded to obtain a silica gel sheet layer.

The coating amount of the magnetic shielding coating layer is 0.5 g / cm 2 , that is, a magnetic silica gel health-care material of the present invention is obtained.

[0016] 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.

[0017] Furthermore, the magnetic silicone health care material is applied to products such as hats, underwear, knee pads, waist pads, etc., which can treat diseases such as hair loss, gray hair, prostatitis, leg pain, back pain, etc., and is beneficial to human health.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (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 a phase change in the crystal structure, thereby improving the magnetic properties and increasing the magnetic energy product. The rare earth materials can be used as permanent magnet materials. Ferroferric oxide is also a permanent magnet material with strong magnetism. It can synergize 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.

[0019] (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 the 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 the air permeability and reduce the discomfort of human skin.

[0020] (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 drug and better exert the efficacy of the drug. The synergistic effect of the two can significantly enhance the therapeutic effect. The present invention also adds calamine, which is a natural zinc carbonate that has a protective effect on the skin and can effectively inhibit bacteria, thereby avoiding allergies and discomfort that may be caused by skin contact with the silica gel material.

[0021] (4) The present invention adds iron silicide, which has a low specific heat capacity. 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 cramps 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.

[0022] (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 acupuncture points on the human body and bonded to the side of the silica gel magnetic material layer close to the human body. The magnetic field strength at the acupuncture points can be strengthened in a targeted manner, thereby enhancing the health care effect.

[0023] (6) The magnetic field shielding layer of the present invention is composed of resin, diluent, dispersant, reinforcing agent and magnetic shielding filler. The resin has adhesiveness, the diluent and additive are used to reduce the viscosity of the resin and wet the filler, the dispersant can fully disperse the conductive filler, the reinforcing agent can increase the adhesion between the magnetic field shielding layer and the silica gel magnetic material layer, the conductive filler is graphite powder, which has good dispersibility, low price and poor conductivity, and is a more ideal magnetic shielding material. The magnetic field shielding layer can be coated on the outside of the silica gel magnetic material layer to avoid the phenomenon of magnetic field weakening or disappearance when the silica gel magnetic material layer is exposed to a stronger magnetic field for a long time, thereby affecting the health care effect.

[0024] (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, gray hair, pain, prostatitis, etc. BRIEF DESCRIPTION OF THE DRAWINGS
