Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen-rich water storage, and particularly to an oily material for preventing hydrogen escape, a preparation method thereof, and a usage method thereof. Background Art

[0002] Hydrogen-rich water is a newly emerging type of health-care drinking water. However, under normal circumstances, hydrogen is completely insoluble in water. After hydrogen-rich water is produced by equipment, it is very easy to escape. At present, there is no suitable container that can be conveniently filled and stored to ensure that the hydrogen content remains at a certain concentration within a certain period. The commonly used large-molecule plastic water buckets in the market cannot "contain" small-molecule hydrogen at all! The hydrogen escapes within one or two days. At present, only bagged hydrogen-rich water can be produced and sold in the market, with too high costs, resulting in too high prices, which seriously affects the marketization and popularization of hydrogen-rich water.

[0003] In Chinese Patent Application No. 202110071398.8, with the patent title "Application of Mannose as a Hydrogen Escape Retarding Agent, Hydrogen-Rich Water and Preparation Method Thereof", it discloses providing a mannose as a hydrogen escape retarding agent, adding mannose to hydrogen-rich water to obtain hydrogen-rich water with a certain degree of inhibition of hydrogen escape.

[0004] Although the hydrogen escape rate in hydrogen-rich water can be slowed down in the above patent, it is impossible to store hydrogen-rich water for a long time. Therefore, there is an urgent need for a method that can long-term preserve hydrogen-rich water and prevent hydrogen escape. Summary of the Invention

[0005] The present invention discloses an oily material for preventing hydrogen escape, a preparation method thereof, and a usage method thereof to solve the problem of how to provide a method that can long-term preserve hydrogen-rich water and prevent hydrogen escape in the above background art.

[0006] To solve the above technical problems, the following technical solutions are now proposed:

[0007] An oily material for preventing hydrogen escape, which is composed of the following components by weight percentage: 90-95% of oil, 4-8% of modifier, and 1-2% of dispersant;

[0008] Among them, the modifier is a eutectic liquid mixture formed by mixing a hydrogen bond donor and a hydrogen bond acceptor.

[0009] Preferably, the hydrogen bond donor is one or more of vitamin C, citric acid, and malic acid;

[0010] The hydrogen bond acceptor is one or more of vitamin BT, betaine, and choline chloride.

[0011] Preferably, the dispersant includes one of sodium polyacrylate, rhamnolipid, sucrose ester, or phosphatidylcholine.

[0012] Preferably, the modifier is a mixture of a hydrogen bond donor and a hydrogen bond acceptor in a molar ratio of 1:1.

[0013] Preferably, the oil is one or more of olive oil, tea oil, palm oil, and grape seed oil.

[0014] The present invention also discloses a preparation method of an oil-based material for preventing hydrogen escape, which is used to produce the oil film for preventing hydrogen escape described in any one of the above. Weigh 90-95% of the oil, 4-8% of the modifier, and 1-2% of the dispersant by weight percentage and add them into the reaction kettle in sequence. Stir at 20-30 °C and a rotation speed of 50-100 r / min for 15-30 min.

[0015] The present invention also discloses a usage method of an oil-based material for preventing hydrogen escape. Apply the oil-based material for preventing hydrogen escape prepared by the preparation method of the oil-based material for preventing hydrogen escape described above. Add the oil-based material into a container filled with hydrogen-rich water so that the oil-based material covers the surface of the hydrogen-rich water. When the escaped hydrogen in the hydrogen-rich water contacts the oil-based material, the oil-based material reacts with the hydrogen to generate a semi-solid oil film layer. The oil film layer and the container form a closed space to prevent hydrogen escape.

[0016] Preferably, before adding the oil-based material into the container, add a water-oil separation membrane into the container, and place the oil film layer on the water-oil separation membrane.

[0017] Preferably, the water-oil separation membrane is made by mixing 80-90% of EVOH resin, 5-10% of sorbitol, and 10-15% of glycerol, extruding them into a thin film, and then soaking them in a 10% sodium alginate solution and a 5% calcium chloride solution respectively, and circulating 3-5 times.

[0018] Preferably, the water-oil separation membrane uniformly covers the surface of the hydrogen-rich water to form a water-oil separation membrane layer with a thickness of 10-100 μm.

[0019] Beneficial effects:

[0020] (1) The eutectic liquid formed by the hydrogen bond acceptor and the hydrogen bond donor not only has antioxidant properties, but also has the function of reducing hydrogen escape. At the same time, these substances are beneficial to the human body and plants to a certain extent.

[0021] (2) The slow hydrogenation reaction between the oil-based material and hydrogen enables the oil film not only to prevent escape, but also to utilize the hydrogen escaped from the hydrogen-rich water to avoid risks.

[0022] (3) By using a water-oil separation membrane with ductility and water-oil separation characteristics, the flow of the oil film can be effectively avoided, making the entire escape membrane system recyclable and more stable. Brief Description of the Drawings

[0023] Figure 1 This is a flowchart of the usage method of the oil-based material for preventing hydrogen escape in the present invention. Detailed Embodiments

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

[0025] The following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] The present invention relates to an oil-based material for preventing hydrogen escape, which is composed of the following components by weight percentage: 90 - 95% of grease, 4 - 8% of modifier, and 1 - 2% of dispersant. The grease is one or a combination of olive oil, tea oil, palm oil, and grape seed oil. A large amount of polyunsaturated fatty acids exist in the above-mentioned grease. Under certain conditions, the polyunsaturated fatty acids will undergo a hydrogenation reaction with hydrogen molecules and then be converted into monounsaturated fatty acids. In the present invention, the grease absorbs the hydrogen escaping from the hydrogen-rich water, causing the grease to form a solidified or semi-solidified oil film layer. The oil film layer forms a closed space with the container for holding the hydrogen-rich water, thereby preventing the continuous escape of hydrogen in the hydrogen-rich water and enabling the long-term storage of the hydrogen-rich water.

[0027] The modifier is a liquid mixture formed by mixing a hydrogen bond donor and a hydrogen bond acceptor, namely a deep eutectic solvent. Deep eutectic solvents (DESs) are a new type of eutectic mixed solvent formed by the complexation of a hydrogen bond acceptor (HBA) and a hydrogen bond donor (HBD). DESs have physical properties similar to those of ionic liquids (ILS), such as similar viscosities, refractive indices, high electrical conductivities, and low surface tensions. However, compared with ILS, DESs have the advantages of simple preparation, low toxicity, biodegradability, biocompatibility, and recyclability, and have become a new alternative to ionic liquids. Among them, the hydrogen bond donors are vitamin C, citric acid, and malic acid, and the hydrogen bond acceptors are vitamin BT, betaine, and choline chloride. The modifier is a deep eutectic solvent, a deep eutectic liquid mixture formed by the strong hydrogen bond interaction between the hydrogen bond donor and the hydrogen bond acceptor. It not only has antioxidant properties, making the oil more stable, but also has a binding effect on hydrogen, so that the hydrogen escaping from the hydrogen-rich water can be captured by the modifier, preventing more hydrogen from escaping from the oil.

[0028] The dispersant includes one of sodium polyacrylate, rhamnolipid, sucrose ester, or phosphatidylcholine. By adding the dispersant to the oil, when the produced oily material is sprayed in a container, the oily material can be evenly dispersed, preventing the oily material from aggregating into oil droplets under stress, so that after the oily material undergoes a hydrogenation reaction with hydrogen molecules to form an oil film layer, it cannot form a sealed space with the container and cannot prevent hydrogen from escaping.

[0029] Among them, vitamin C can not only participate in the complex metabolic processes of the animal body, promote growth and enhance resistance to diseases, but also be used as a nutritional supplement and antioxidant. In agriculture, vitamin C can also improve the soil matrix and promote plant growth.

[0030] As natural biodegradable organic acids, citric acid and malic acid can not only effectively promote the germination of seeds, but also improve the germination potential, germination rate, germination index, and vigor index of seeds; at the same time, they can promote the plant roots to secrete more beneficial substances such as organic acids to promote plant growth.

[0031] Betaine is a non-toxic osmotic regulator widely distributed in microorganisms, higher plants, and animals, with relatively stable physical and chemical properties. A number of studies have shown that under stress, plants can induce small molecule substances such as betaine and proline in the body to improve the osmotic adjustment ability of cells, reduce the damage to the structure and function of membranes, enzymes, and proteins caused by osmotic water loss, and thus improve the stress resistance of plants.

[0032] Choline chloride (CC) is a quaternary amine base. After entering the plant body, it is converted into phosphatidylcholine, thus having a repair effect on the membrane system. Exogenous application of CC can alleviate the damage of salt stress to plants by reducing membrane lipid peroxidation, inhibiting chlorophyll decomposition, and increasing the accumulation of proline and betaine. Secondly, choline chloride is a B vitamin and is often used as an animal feed supplement.

[0033] Sodium polyacrylate, with the chemical formula (C3H3NaO2)n, is a new type of functional polymer material and an important chemical product. The solid product is white or light yellow block or powder, and the liquid product is colorless or light yellow viscous liquid, odorless. It can be used in industries such as food, feed, and water treatment. Sodium polyacrylate with low molecular weight (generally below 10,000, preferably 500 - 5000) is a good dispersant and has good dispersion effect.

[0034] Rhamnolipid is a biosurfactant with biological metabolic properties produced by Pseudomonas or Burkholderia. It belongs to a kind of glycolipid anionic surfactant. Rhamnolipid can be used on crops, vegetables, fruits, and flowers for stimulating growth, assisting in nutrient absorption, increasing the effects of pesticides and fertilizers, etc., and has been proven to be non-toxic to humans and animals. In addition to having good surface activity, rhamnolipid also has good cell permeability. It is derived from biology and has good non-toxic and degradable characteristics.

[0035] Sucrose ester is a non-ionic surfactant with excellent performance. Its sucrose part is the hydrophilic group, and the long-chain fatty acid part is the lipophilic group. The more the content of monoesters, the more hydrophilic it is; while for diesters... It is harmless to humans, does not irritate the skin and mucous membranes, is non-toxic; has no pollution, and can be completely biodegradable.

[0036] It should be noted that the oils, modifiers, and dispersants used in the examples are all substances harmless to humans, animals, or plants. Secondly, among the modifiers, the chemical properties of vitamin C, citric acid, malic acid, vitamin BT, betaine, and choline chloride show great guarantee of the safety when using oily materials with many natural components in animals and plants. Therefore, even if the oily materials are in direct contact with hydrogen-rich water during use and some substances in the oil film dissolve in the hydrogen-rich water, these hydrogen-rich waters will not only not harm humans or other animals and plants, but also promote plant growth.

[0037] In this embodiment, the modifier is a mixture of a hydrogen bond donor and a hydrogen bond acceptor in a molar ratio of 1:1. The antioxidant properties and hydrogen-binding ability of the eutectic solvents formed at different ratios are different. When the molar ratio of the hydrogen bond donor to the hydrogen bond acceptor is less than 1:1, the antioxidant properties and hydrogen-binding ability of the eutectic solution will be weakened. When the molar ratio of the hydrogen bond donor to the hydrogen bond acceptor is too high, the production cost will increase significantly. Therefore, in this embodiment, it is preferred that the modifier is a mixture of a hydrogen bond donor and a hydrogen bond acceptor in a molar ratio of 1:1.

[0038] A preparation method of an oil-based material for preventing hydrogen escape is also disclosed, which is used to produce the oil film for preventing hydrogen escape according to any one of the above. Weigh 90-95% of the grease, 4-8% of the modifier, and 1-2% of the dispersant by weight percentage and add them into the reaction kettle in sequence. Stir at 20-30 °C and a rotation speed of 50-100 r / min for 15-30 min.

[0039] A usage method of the oil-based material for preventing hydrogen escape is also disclosed. Refer to Figure 1 , for the oil-based material for preventing hydrogen escape prepared by the preparation method of the oil-based material for preventing hydrogen escape described above, add the oil-based material into a container filled with hydrogen-rich water so that the oil-based material covers the surface of the hydrogen-rich water. When the hydrogen escaping from the hydrogen-rich water contacts the oil-based material, a hydrogenation reaction occurs between the oil-based material and the hydrogen, generating a semi-solid oil film layer. The oil film layer and the container form a closed space to prevent hydrogen escape.

[0040] In this embodiment, during the use process, since the process of the oil-based material reacting with hydrogen molecules to generate a semi-solid oil film layer requires a certain reaction time, and not all oil films can generate a semi-solid oil film layer. Therefore, a part of the oil film remains in a liquid state during the use process. Therefore, to prevent the oil-based material from being taken out together with the hydrogen-rich water when taking out the hydrogen-rich water in the container, which may cause pollution, before adding the oil-based material into the container, add a water-oil separation membrane into the container. The oil film layer is placed on the water-oil separation membrane, forming a water-oil separation membrane on the surface of the hydrogen-rich water. While ensuring that hydrogen can contact the oil film, the oil film can be separated from the hydrogen-rich water. At the same time, the oil film layer and the water-oil separation membrane combine to form an anti-escape membrane for preventing hydrogen escape, which can better prevent hydrogen escape.

[0041] Specifically, the water-oil separation membrane is made by mixing 80-90% of EVOH resin, 5-10% of sorbitol, and 10-15% of glycerol and extruding them into a thin film with a thickness of 10-100 μm, and then soaking them in a 10% sodium alginate solution and a 5% calcium chloride solution respectively for 3-5 cycles.

Then spray the oily material into the container so that the oily material covers the water-oil separation membrane layer. After the oily material reacts with the hydrogen escaping from the hydrogen-rich water in the container, a semi-solid oil film layer with a thickness of 5 μm is formed. The oil film layer and the container form a sealed storage cavity to prevent the continuous escape of hydrogen in the hydrogen-rich water.

[0050] (3) Add an appropriate amount of hydrogen-rich water into the container.

Then spray the oily material into the container so that the oily material covers the water-oil separation membrane layer. After the oily material reacts with the hydrogen escaping from the hydrogen-rich water in the container, a semi-solid oil film layer with a thickness of 10 μm is formed. The oil film layer and the container form a sealed storage cavity to prevent the continuous escape of hydrogen in the hydrogen-rich water.

[0051] Example 3:

[0052] (1) Preparation of water-oil separation membrane: Weigh 80% of EVOH resin, 10% of sorbitol, and 10% of glycerol by weight percentage, mix and extrude them into a thin film, then soak the film in 10% sodium alginate solution and 5% calcium chloride solution respectively, and cycle 3 - 5 times;

After the oily material reacts with the hydrogen gas escaping from the hydrogen-rich water in the container, a semi-solid oil film layer with a thickness of 20 μm is generated. The oil film layer and the container form a closed storage cavity to prevent the hydrogen in the hydrogen-rich water from continuing to escape.

[0058] Experimental design: Each container is filled with an equal amount of 1600ppb hydrogen-rich water, and the container is sealed.

[0059] Table 1 Changes in hydrogen content of hydrogen-rich water under different treatments (ppb)

[0060]

[0061]

[0062] Conclusion: The hydrogen-rich water without any anti-escaping layer all escaped hydrogen after 1 hour. The hydrogen content of the control group 1, i.e. the hydrogen-rich water without water-oil separation membrane, decreased rapidly with the increase of time, and uneven white semi-solid oil appeared, which was also the main factor causing the hydrogen escape. In the anti-escaping membrane under the joint action of oily material and water-oil separation membrane, the hydrogen content in the hydrogen-rich water was relatively stable, and there was little white solid in the upper layer. This may be because hydrogen is less likely to escape and react with oil under the action of water-oil separation membrane, thus making the hydrogen-rich water in a relatively closed space.

[0063] The above are only several specific embodiments of the present invention disclosed, but the present invention is not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
