Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen-dissolving materials, and in particular to a high-efficiency hydrogen-dissolving material and a preparation method thereof. Background Art

[0002] The normal dissolved hydrogen in water at room temperature and pressure is about 1500ppm. To obtain supersaturated hydrogen water, high-pressure hydrogen dissolution is generally used, and other methods include ultrasonic and circulating hydrogen dissolution. Hydrogen is dissolved in drinking water. After drinking, the water and hydrogen can be quickly absorbed by the body. The hydrogen in the water can directly enter the cell nucleus, play a role in removing oxidative free radicals and reducing oxidation, can repair cells and prevent many chronic diseases. The higher the concentration of hydrogen in the water, the better the effect.

[0003] After searching, the Chinese patent application number CN2019100961552 discloses a hydrogen-soluble aqueous solution and a preparation method thereof, wherein the hydrogen-soluble aqueous solution contains 8-10ppm of hydrogen. Ordinary water (large molecular cluster water) enters through the water inlet of the micro-nano generator, and is cut by a rotary cutter. After the cutting is completed, it passes through a filter, and ordinary water becomes small molecular cluster water (the greater the density of the molecular cluster water, the higher the dissolved hydrogen concentration). Through micro-nano technology, the structure of hydrogen molecules and water molecules can be changed, and its structure is transformed into a quantum mechanical effect. The hydrogen-soluble water formed by the cutting micro-nano dissolution pressure technology can quickly repair and improve human cells and mitochondria, increase cell energy and immunity, and remove oxidative hydroxyl radicals from the body. A hydrogen-soluble aqueous solution and a preparation method thereof in the above-mentioned patent have the following deficiencies: Although the above method achieves the fusion of hydrogen and water in the form of a pressure tank, the hydrogen in the water will quickly escape as the pressure of the pressure tank decreases, and the amount of hydrogen actually reaching the human body does not increase, resulting in a decrease in the quality of dissolved hydrogen and a decrease in the amount of hydrogen that the human body can absorb. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-efficiency hydrogen-dissolving material and a preparation method thereof.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A high-efficiency hydrogen-dissolving material comprises PES, a binder, a solvent, a dispersant, cellulose, an anticoagulant and an organic pore-forming agent, wherein the mass percentages thereof are as follows: PES 42%-50% Adhesive 20%-22% Solvent 5%-6% Dispersant 2.5%-3% Cellulose 2.5%-4% Anticoagulants 7%-7.5% Organic pore former 10%-12%.

[0006] Preferably: the PES is a polyethersulfone resin, and the polyethersulfone resin can be replaced by any one of polypropylene, polyethylene and polyethylene terephthalate; the adhesive is selected from any at least one of polyurethane, chitosan, epoxy resin, melamine and vinyl acrylate; the solvent is selected from any one of dimethylacetamide, N-methylpyrrolidone and acetone; the dispersant is selected from any at least one of polyvinyl pyrrolidone, hydroxypropyl methylcellulose, polyethylene glycol and hydroxypropyl methacrylate.

[0007] Furthermore: the cellulose is selected from any one of protein fiber and polyester fiber; the anticoagulant is selected from any one of heparin iron nanoparticles and polylactic acid-polyethylene glycol copolymer; the organic pore-forming agent is selected from any at least one of phthalates, γ-butyrolactone, benzoates, sebacates, adipates, trimellitates or phosphates.

[0008] On the basis of the above scheme: the mass parts of the PES, binder, solvent, dispersant, cellulose, anticoagulant and organic pore-forming agent are as follows: PES 60-100 parts, binder 30-40 parts, solvent 7-12 parts, dispersant 3-6 parts, cellulose 5-8 parts, anticoagulant 9-15 parts, organic pore former 16-20 parts.

[0009] A more preferred solution in the above solution is that the mass parts of the specific components of the PES, binder, solvent, dispersant, cellulose, anticoagulant and organic pore-forming agent are as follows: 7 parts of polyethersulfone resin, 32 parts of polyurethane, 9 parts of acetone, 5 parts of hydroxypropyl methacrylate, 6 parts of protein fiber, 11 parts of polylactic acid-polyethylene glycol copolymer, and 16 parts of γ-butyrolactone.

[0010] A method for preparing a high-efficiency hydrogen-dissolving material comprises the following steps: The PES, adhesive, solvent, dispersant, cellulose, anticoagulant and organic pore-forming agent are mixed to prepare a hollow fiber membrane, and the specific preparation steps of the hollow fiber membrane are as follows: S1: preparing a solution of polyethersulfone resin and mixing it for use, and at the same time dissolving a binder, a dispersant, cellulose, an anticoagulant and an organic pore-forming agent in a solvent and mixing them to obtain a mixed solution for use; S2: putting the polyethersulfone resin solution and the mixed solution into a reaction kettle for vacuum mixing, the mixing temperature is controlled at 50-75°C, the mixing speed is 500-700r / min, the mixing time is 6-13h, and a membrane mixture is obtained after mixing; S3: putting the membrane mixture into an extruder, controlling the temperature to 140-250° C., introducing air, and extruding hollow fiber membrane filaments; S4: cooling the extruded hollow fiber membrane filament, and stretching the cooled hollow fiber membrane filament at a length ratio of 2 to 5 times in the length direction at a temperature of 20 to 90° C.; S5: extracting the organic pore-forming agent and solvent in the hollow fiber membrane formed after stretching by a polar solvent, and the extraction temperature is controlled at 20 to 80° C.; S6: After the elution treatment, the hollow fiber membrane is washed with pure water and then heat-set at a temperature controlled at 120-200°C.

[0011] Meanwhile, the S3 step can be replaced by the following specific steps: A1: Drop the membrane mixture onto a flat table surface to volatilize the solvent in the membrane mixture and gradually solidify it into a thin film; A2: The film is introduced into a rotary spinning machine, and the rotary spinning machine performs spinning to form a hollow fiber membrane filament; A3: During the spinning process, the unvolatile solvent will evaporate again during its movement.

[0012] As a preferred embodiment of the present invention, the step A1 can be replaced by the following specific steps: dripping the film mixture onto a rotating table, and evenly coating the film mixture on the table surface by centrifugal force, while the film mixture is easily volatile and gradually solidifies into a thin film.

[0013] Meanwhile, the heat setting treatment has the following working steps: C1: The hollow fiber membrane is cleaned and placed in a heat treatment device to heat the polymer resin molecules in the membrane to cause thermal motion, so that the polymer resin molecules are fully cross-linked and crystallized; C2: After the heat setting treatment, the intermittent cooling method is used to solidify the polymer resin in the film and maintain the desired structure; C3: Test the surface quality, structural stability and separation performance of the prepared hollow fiber membrane.

[0014] As a more optimal solution of the present invention: in the step S4, the cooling temperature of the hollow fiber membrane filament is 25°C, and the length stretching ratio of the hollow fiber membrane filament is 3.2 times, and the temperature under stretching is controlled to be 67°C.

[0015] The beneficial effects of the present invention are: 1. This is a highly efficient hydrogen-soluble material and its preparation method. The material can also be made into a hollow fiber tube or a flat coating. Hydrogen penetrates from one side into the water on the other side through micropores to form hydrogen water with high hydrogen value, good stability at normal pressure, and high hydrogenation efficiency. This material is made into a 40-100um thick membrane or a hollow fiber membrane to form pores of 1 to 5um, so that the pressure difference passing through reaches 0.5 to 4 bar, which effectively ensures the quality of hydrogen water absorbed into the human body.

[0016] 2. This kind of high-efficiency hydrogen-dissolving material and its preparation method, by dropping a membrane mixture onto a flat table surface, volatilizing the solvent in the membrane mixture, and gradually solidifying it into a thin film, has the advantages of being simple and easy to operate, widely applicable, highly controllable, suitable for large-area preparation and low cost. At the same time, the film is introduced into a rotary spinning machine, and the rotary spinning machine is used for spinning to make it into a hollow fiber membrane filament, thereby ensuring the efficiency of the preparation of the hollow fiber membrane filament.

[0017] 3. This is a highly efficient hydrogen-dissolving material and a preparation method thereof. The membrane mixture is dripped onto a rotating table, and the membrane mixture is evenly coated on the surface of the table by centrifugal force. At the same time, the easily volatilized substances in the membrane mixture gradually solidify into a thin film, thereby achieving precise control of the film thickness and ensuring the preparation of a film of the required thickness. The centrifugal force evenly distributes the solution on the surface of the table, so that a smooth and uniform film can be obtained, thereby improving the quality and performance of the membrane.

[0018] 4. This kind of high-efficiency hydrogen-dissolving material and its preparation method, by heat-setting the hollow fiber membrane fibers, enhances the cross-linking and crystallization degree of the polymer resin molecules, thereby improving the thermal stability and chemical stability of the membrane, making it more durable; and helps to optimize the pore structure and surface morphology of the membrane, improve separation efficiency and selectivity, and enhance the performance of the membrane in applications such as separation and filtration.

[0026] Among them, step S3 can be replaced by the following specific steps: A1: Drop the membrane mixture onto a flat table surface to volatilize the solvent in the membrane mixture and gradually solidify it into a thin film; A2: The film is introduced into a rotary spinning machine, and the rotary spinning machine performs spinning to form a hollow fiber membrane filament; A3: During the spinning process, the unvolatile solvent will evaporate again during its movement.

[0027] The preparation of the film by the above steps has the advantages of being simple, easy, widely applicable, highly controllable, suitable for large-area preparation and low cost, while ensuring the efficiency of the preparation of the hollow fiber membrane filaments.

[0028] The heat setting process comprises the following steps: C1: The hollow fiber membrane is cleaned and placed in a heat treatment device to heat the polymer resin molecules in the membrane to cause thermal motion, so that the polymer resin molecules are fully cross-linked and crystallized; C2: After the heat setting treatment, the intermittent cooling method is used to solidify the polymer resin in the film and maintain the desired structure; C3: Test the surface quality, structural stability and separation performance of the prepared hollow fiber membrane.

[0030] In the step S4, the cooling temperature of the hollow fiber membrane filament is 25°C, the length stretching ratio of the hollow fiber membrane filament is 3.2 times, and the temperature under stretching is controlled to be 67°C. Example 5

[0031] A method for preparing a highly efficient hydrogen-dissolving material, wherein the polyethersulfone resin, adhesive, solvent, dispersant, cellulose, anticoagulant and organic pore-forming agent are mixed to prepare a hollow fiber membrane, and the specific preparation steps of the hollow fiber membrane are as follows: S1: preparing a solution of polyethersulfone resin and mixing it for use, and at the same time dissolving a binder, a dispersant, cellulose, an anticoagulant and an organic pore-forming agent in a solvent and mixing them to obtain a mixed solution for use; S2: putting the polyethersulfone resin solution and the mixed solution into a reaction kettle for vacuum mixing, the mixing temperature is controlled at 50-75°C, the mixing speed is 500-700r / min, the mixing time is 6-13h, and a membrane mixture is obtained after mixing; S3: putting the membrane mixture into an extruder, controlling the temperature to 140-250° C., introducing air, and extruding hollow fiber membrane filaments; S4: cooling the extruded hollow fiber membrane filament, and stretching the cooled hollow fiber membrane filament at a length ratio of 2 to 5 times in the length direction at a temperature of 20 to 90° C.; S5: extracting the organic pore-forming agent and solvent in the hollow fiber membrane formed after stretching by a polar solvent, and the extraction temperature is controlled at 20 to 80° C.; S6: After the elution treatment, the hollow fiber membrane is washed with pure water and then heat-set at a temperature controlled at 120-200°C.

[0032] Among them, step S3 can be replaced by the following specific steps: A1: Drop the membrane mixture onto a flat table surface to volatilize the solvent in the membrane mixture and gradually solidify it into a thin film; A2: The film is introduced into a rotary spinning machine, and the rotary spinning machine performs spinning to form a hollow fiber membrane filament; A3: During the spinning process, the unvolatile solvent will evaporate again during its movement.

[0033] Among them, step A1 can be replaced by the following specific steps: dripping the membrane mixture onto a rotating table, and evenly coating the membrane mixture on the surface of the table by centrifugal force. At the same time, the easily volatile substances in the membrane mixture gradually solidify into a thin film.

[0036] Example: A comparison experiment was conducted on the hydrogen content in the hydrogen water prepared by high pressure and hollow fiber membrane, as shown in the following table:

[0037] Under the three conditions of controlling the amount of hydrogen injected, the amount and temperature of water, and the time for dissolving hydrogen, it can be seen from the above table that the hollow fiber membrane prepared by the hydrogen-soluble material in this case has the best hydrogen content in the hydrogen water prepared. Furthermore, it is concluded that under normal pressure, using the hollow fiber membrane as a separation membrane, the hydrogen content of the hydrogen water obtained by injecting hydrogen into water is greater than the hydrogen content of the hydrogen water prepared under high pressure in a confined space. It is concluded that the hollow fiber membrane prepared by the hydrogen-soluble material in this case is more efficient and simpler to prepare supersaturated hydrogen water.
