In order to relieve visual fatigue, a variety of eyeglass products with the function of relieving eye fatigue have appeared on the market.

[0003] For example, patent CN209060339U discloses a liquid medicine that can be placed in a spectacle frame to treat dry eyes and relieve visual fatigue, which belongs to the field of spectacle frame technology. The method includes: leaving space in the spectacle frame to place a volatile liquid medicine, which has the effect of relieving visual fatigue. However, this method has the problems of small storage capacity and fast volatilization, resulting in frequent replacement of the liquid medicine, and the concentration of the liquid medicine leads to a limited range of action.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The present application provides an organic composite material, which uses carbon fiber as a carrier and can more effectively adsorb compound essential oils. Compared with traditional small liquid medicine storage spaces or liquid adsorption blocks, the high load capacity and structural stability of carbon fiber can allow for a larger storage of essential oils, thereby reducing the frequent replacement of liquid medicines or adsorption blocks; the carbon fiber can also help slow down the volatilization rate of the compound essential oil to extend its duration of action; and the compound essential oil is composed of volatile active components extracted from Poria cocos, Angelica sinensis, Lycium barbarum, Cassia seed, Raspberry, Lutein and Coptis chinensis, which can produce a synergistic effect to relieve visual fatigue and improve eye health;

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0041] In the drawings, the size of the constituent elements, the thickness of the layer or the area may be exaggerated for the sake of clarity. Therefore, any implementation of the present disclosure is not necessarily limited to the size shown in the drawings, and the shapes and sizes of the components in the drawings do not reflect the true proportions. In addition, the drawings schematically show ideal examples, and any implementation of the present disclosure is not limited to the shapes or values ​​shown in the drawings.

[0042] In the related art, it has become the norm for modern people to face electronic screens for a long time in daily life and work. However, staring at the electronic screen for a long time will not only lead to decreased vision, but also cause eye fatigue problems, which manifest as dry eyes, stinging, blurred vision, tears, eye muscle tension and other discomfort symptoms. In order to alleviate the problems caused by eye fatigue, many people choose to wear glasses with anti-blue light, radiation protection and other functions. However, most of the existing eyewear products focus on physical protection, while ignoring the eye's own adjustment and relief needs. Therefore, the related art proposes to fill a small amount of liquid medicine in the frame of the glasses, and the liquid medicine evaporates to relieve eye fatigue and improve eye health. However, these methods are common, with problems such as small liquid medicine inventory and limited volatilization range.

[0043] Based on the above problems, the present application proposes to prepare a new type of organic composite material, so that the material itself has the effect of slow-release compound essential oil. This material is used as a raw material and is made into a spectacle frame plate together with other materials, so that volatile active ingredients are distributed at any position inside the plate. When the spectacle frame made of it is worn, the compound essential oil has a larger volatilization range and a wider effective area, and the relief or improvement effect on the eyes is more obvious and the action time is longer. It can stably and continuously release the active ingredients, overcoming the problems in the prior art.

[0044] Specifically, an embodiment of the present application provides an organic composite material, wherein the organic composite material uses carbon fiber as a carrier and is loaded with a compound essential oil composition;

[0045] The compound essential oil is composed of volatile active components extracted from Poria cocos, Chinese angelica, Chinese wolfberry, cassia seed, raspberry, lutein and coptis root;

[0046] The loading amount of the compound essential oil on the carbon fiber is 10 mL / kg-70 mL / kg.

[0047] In specific implementation, the carbon fiber selected in the embodiment of the present application has the characteristics of being gentle to the skin, having strong stability, high plasticity, and excellent comfort. Secondly, the porous structure of the carbon fiber as a carrier helps to absorb and retain the compound essential oil, allowing it to evaporate slowly, thereby slowing down the volatilization rate of the compound essential oil, thereby extending the duration of a single use of the compound essential oil;

[0048] The compound essential oil is composed of active ingredients extracted from a variety of natural Chinese medicinal herbs. Compared with other types of liquid medicines, it is gentler and safer and will not cause irritation or discomfort to the eyes. Ingredients such as Poria cocos, Angelica sinensis, Lycium barbarum, Cassia seed, Raspberry, Lutein and Coptis chinensis all have the effect of improving eyesight and can work synergistically to effectively relieve uncomfortable symptoms such as dryness and soreness caused by visual fatigue.

[0049] In some embodiments, the loading amount of the compound essential oil on the carbon fiber is 30 mL / kg-50 mL / kg.

[0050] In some embodiments, the carbon fibers are graphite fibers having a carbon content greater than 99%.

[0051] In specific implementation, graphite fiber has extremely high strength and modulus. The organic composite material composed of graphite fiber as the carrier is more stable when subjected to external force and is not easy to deform or break. Graphite fiber with high carbon content has excellent thermal stability and chemical stability, which helps the compound essential oil to evaporate stably over a long period of time without destroying the ingredients.

[0052] In some embodiments, the mass ratio of Poria cocos, Angelica sinensis, Lycium barbarum, Cassia seed, Rubus idaeus, lutein and Coptis chinensis used to extract the compound essential oil is (5-10): (5-10): (10-15): (15-20): (10-15): (10-20): (5-10).

[0053] In specific implementation, different Chinese medicinal materials contain different active ingredients, and the interaction between the ingredients will affect the stability and volatility of the essential oil. Therefore, by limiting the mass ratio, the amount of active components extracted from each Chinese medicinal material can be controlled, making the compound essential oil composed of them more stable and easy to volatilize, and maximizing the synergistic effect between the components. It also helps to ensure the safety of the compound essential oil during use and reduce potential health risks.

[0054] In the specific implementation, the mass ratio of Poria cocos, Chinese angelica, wolfberry, cassia seed, raspberry, lutein and coptis chinensis for extracting the compound essential oil is 5:10:10:15:15:10:10, 10:5:15:20:10:20:5 or 5:10:10:15:15:10:10.

[0055] The present application also provides a method for preparing the above-mentioned organic composite material, comprising:

[0056] Immersing the carbon fiber in the compound essential oil for 1 h to 5 h, so that the compound essential oil is loaded on the carbon fiber to obtain the organic composite material;

[0057] The loading amount of the compound essential oil in the carbon fiber is 10 mL / kg-70 mL / kg.

[0058] In specific implementation, the carbon fiber is immersed in the compound essential oil for 1 h-5 h, so that the compound essential oil fully penetrates into the pores of the carbon fiber to achieve efficient loading. The preparation method is relatively simple and easy to operate and control. By directly immersing the carbon fiber in the compound essential oil, no complicated chemical reaction or equipment is required, which helps to reduce preparation costs and improve production efficiency.

[0059] In some embodiments, the carbon fiber needs to be cleaned and dried before impregnation to make the surface of the carbon fiber clean and free of impurities to achieve better adsorption performance.

[0060] The reagents used for cleaning the carbon fiber include, but are not limited to, alcohol, acetone, methyl isobutyl ketone, xylene, and trichloroethylene.

[0061] In some embodiments, see Figure 1 , the specific preparation steps of the organic composite material include:

[0062] Step S1: immersing the carbon fiber in the compound essential oil for 1 h to 5 h, so that the compound essential oil is loaded on the carbon fiber to obtain an organic product;

[0063] Step S2: placing the obtained organic product in an oven and drying it at 60°C-100°C for 1 h-4 h to obtain an organic composite material.

[0064] In some embodiments, the carbon fiber is immersed in the compound essential oil for 2 h-4 h.

[0065] By optimizing the immersion time of carbon fiber in the compound essential oil, on the one hand, the compound essential oil can be evenly loaded on the carbon fiber, and on the other hand, it is avoided that the carbon fiber is immersed for too long, which leads to a decrease in the strength of the carbon fiber.

[0066] In some embodiments, in step S2, nitrogen gas may be introduced into the oven, which helps to remove excess compound essential oil on the surface of the organic composite material after heating, making the surface of the organic composite material drier after drying.

[0067] In some embodiments, see Figure 2 , the extraction method of the compound essential oil comprises:

[0068] Step S11: extracting Poria cocos, Chinese angelica, wolfberry, cassia seed, raspberry, lutein and coptis chinensis as raw materials under the action of a gaseous extractant to obtain a first essential oil containing 5%-30% of active components and a solid-liquid mixture;

[0069] Step S12: adding a liquid extractant to the solid-liquid mixture, taking an upper layer of liquid after standing for stratification to obtain a second essential oil containing 60%-90% of the active component, and mixing the first essential oil and the second essential oil to obtain the compound essential oil;

[0070] The liquid extractant is any one of ethyl acetate, ethanol and petroleum ether.

[0071] In specific implementation, by adopting a method combining gas phase extraction and liquid extraction, the volatile active components in the traditional Chinese medicine composition can be extracted more efficiently, thereby increasing the content of active components in the compound essential oil.

[0072] Since the compound essential oil contains a higher content of active ingredients, when used, it can more effectively relieve symptoms such as dryness, soreness, etc. caused by visual fatigue.

[0073] The Chinese medicine composition for preparing the compound essential oil in the embodiment of the present application not only includes Chinese medicine ingredients that are beneficial to the eyes, such as cassia seed and raspberry, but also Chinese medicine ingredients with antibacterial and anti-inflammatory effects such as lutein and coptis root, thereby enhancing the comprehensive improvement effect of the compound essential oil and realizing the functional diversification of the organic composite material.

[0074] In specific implementation, gas phase extraction is first used to recover some volatile active components from various natural Chinese herbal medicines, while removing some compounds that hinder subsequent extraction, such as silicates, etc., thereby shortening the extraction time and improving the extraction efficiency.

[0075] In some embodiments, see Figure 3 , the extraction comprises:

[0076] Step S111: mixing the Poria cocos, Angelica sinensis, Lycium barbarum, Cassia seed, Rubus idaeus, lutein and Coptis chinensis, introducing the gaseous extractant into the obtained traditional Chinese medicine composition, and extracting the active components in the traditional Chinese medicine composition under the conditions of 60° C.-100° C. and 0.1 MPa-5 MPa;

[0077] Step S112: After the obtained product is condensed, n-hexane is added, and the product is allowed to stand for stratification and the upper layer is taken to obtain the first essential oil, and the remaining material is the solid-liquid mixture;

[0078] The gaseous extractant is water vapor or nitrogen.

[0079] In specific implementation, during the extraction, the temperature is 60 ℃-100 ℃ and the pressure is 0.1 MPa-5 MPa, wherein the heating can cause the various components of the traditional Chinese medicine to swell, making it easier for the gaseous extractant to extract the active components therein, so as to achieve a faster and more accurate extraction reaction.

[0080] In some embodiments, the extracting further comprises:

[0081] placing the weighed Chinese herbal composition in a reactor, introducing a gaseous extractant into a reaction chamber of the reactor, the gaseous extractant propagating through the reaction chamber and separating the active component from the substantially solid Chinese herbal composition, and the gaseous extractant leaving the reaction chamber is condensed to produce a liquid extract rich in the active component;

[0082] The reactor is constructed as a batch reactor or a continuous flow reactor. During extraction, the temperature in the reactor is adjusted to 60°C-100°C, and the pressure in the reactor is adjusted to 0.1 MPa-5 MPa. The flow rate of the gaseous extractant passing through the reactor is then adjusted to keep the residence time of the separated traditional Chinese medicine composition in the reactor at 1 min-30 min, ensuring that the first essential oil with an active component content of 5%-30% can be extracted during recovery.

[0083] In some embodiments, the gaseous extractant extracts the active components in the traditional Chinese medicine composition under the conditions of 70°C-90°C and 0.5 Mpa-1.5 Mpa.

[0084] In specific implementation, the gaseous extractant extracts the active components in the traditional Chinese medicine composition at a temperature of 70°C, 75°C, 80°C, 85°C or 90°C and a pressure of 0.5Mpa, 0.6Mpa, 0.7Mpa, 0.8Mpa, 0.9Mpa, 1.0Mpa, 1.1Mpa, 1.2Mpa, 1.3Mpa, 1.4Mpa or 1.5Mpa.

[0085] An embodiment of the present application also provides an application of the above-mentioned organic composite material, wherein the organic composite material is used as a component raw material of eyeglass frame plate material to prepare eyeglass frames.

[0086] During specific implementation, since the organic composite material provided by the embodiment of the present application uses carbon fiber as a carrier and loads compound essential oil, the eyeglass frame plate made of it can achieve stable load and lasting release of compound essential oil. The eyeglass frame made of the plate is stored with compound essential oil as a whole, which expands the storage space of compound essential oil, solves the problem of small storage capacity and fast volatilization of liquid medicine, and does not need to replace liquid medicine or compound essential oil. Through the uniform distribution of these active components in the eyeglass frame plate, the scope of action of the compound essential oil is wider, and the surrounding area of ​​the eye can be covered more comprehensively, thereby enhancing the symptoms of soreness and dryness caused by relieving eye fatigue, and being more conducive to improving eye health. At the same time, the combination of carbon fiber and compound essential oil also gives the eyeglass frame plate more functionality, such as antibacterial and antiallergic, meeting the diverse needs of different groups of people for eye health products.

[0087] In some embodiments, the application includes:

[0088] The titanium-zinc alloy core plate is used as the substrate, and 150 g / m 2 -250g / m 2 At a rate of , apply epoxy resin glue with an epoxy value of 0.35;

[0089] The organic composite material is spread on the epoxy resin glue, and hot-pressed at 60°C-100°C and 0.5 MPa, and then kept hot and pressed for 2 hours for curing and molding to obtain the eyeglass frame plate, which is used to prepare eyeglass frames.

[0090] In specific implementation, the titanium-zinc alloy core plate has the characteristics of high strength, corrosion resistance and light weight. Using the titanium-zinc alloy core plate as the middle layer can enhance the elastic modulus and yield strength of the plate and increase the service life of the plate; the epoxy resin glue has good sealing and permeability, which can enhance the bonding force between the organic composite material and the titanium-zinc alloy core plate, making the organic composite material not easy to peel or fall off. During preparation, by limiting the temperature, pressure and time of the hot pressing treatment, it is helpful to control the stability and dimensional accuracy of the plate structure.

[0091] In summary, the plate material prepared in the embodiment of the present application uses a titanium-zinc alloy core plate as the middle layer and an organic composite material as the inner and outer layers to prepare a new type of eyeglass frame plate material. The plate material not only has excellent structural stability and durability, but also can release the active components in the compound essential oil for a long time, effectively relieve visual fatigue, and improve the improvement effect.

[0092] In order to enable those skilled in the art to more clearly understand the present invention, an organic composite material, a preparation method and an application thereof according to the present invention are now described in detail through the following examples.

[0093] Example 1

[0094] (1) Preparation of a compound essential oil:

[0095] 1) Accurately weigh 5 g of Poria cocos, 10 g of Angelica sinensis, 10 g of Lycium barbarum, 15 g of Cassia seed, 15 g of Rubus idaeus, 10 g of Lutein, and 10 g of Coptis chinensis, and mix them to obtain a Chinese medicine composition;

[0096] 2) Place the Chinese medicine composition in a reactor, continuously introduce water vapor for 15 min, extract the active components in the Chinese medicine composition under the conditions of 80°C and 1 MPa, condense the obtained product to room temperature, add n-hexane for extraction, let stand and separate the layers, and take the upper layer to obtain the first essential oil containing 20% ​​of the active components, and the remaining material is a solid-liquid mixture;

[0097] 3) Add ethanol to the solid-liquid mixture, let it stand at room temperature for stratification, and take the upper liquid to obtain a second essential oil containing 75% of the active component. Mix the first essential oil and the second essential oil to obtain a transparent oily compound essential oil with a special smell.

[0098] (2) Preparation of an organic composite material:

[0099] 1) Immerse the carbon fiber in the compound essential oil for 2.5 h, so that the compound essential oil is loaded on the carbon fiber to obtain an organic composite material;

[0100] 2) The obtained organic composite material was placed in an oven and dried at 80°C for 2 h. In the dried organic composite material, the loading amount of the compound essential oil on the carbon fiber was 40 mL / kg.

[0101] Based on Example 1, see Figure 4 , Figure 4 The microscopic SEM images of the particles before and after the carbon fiber loaded with the compound essential oil proposed in Example 1 of the present application are shown. Figure 4 (a) shows the microstructure of carbon fiber before loading compound essential oil. Figure 4 (b) shows the microstructure of carbon fibers after loading the compound essential oil.

[0102] according to Figure 4 It can be seen that the compound essential oil is evenly loaded in the pores of the carbon fiber, which proves that Example 1 of the present application uses carbon fiber as a carrier to evenly load the compound essential oil, and utilizes its porous structure to achieve the effect of sustained release of the compound essential oil.

[0103] Since the compound essential oil is more distributed in the pores of the carbon fiber, and only a small part is impregnated on the surface of the carbon fiber, the organic composite material does not produce a sticky feeling when used. Furthermore, when the organic composite material is used to prepare the eyeglass frame plate, physical means such as grinding and polishing can be used to further remove the compound essential oil on the surface of the plate to enhance the comfort when wearing. Since the compound essential oil is less distributed on the surface, the loss caused by grinding does not affect the effect of the compound essential oil in relieving eye fatigue and dryness.

[0104] See also Figure 5 , Figure 5 The infrared spectrum of the organic composite material prepared in Example 1 of the present application is shown. Figure 5 (1) in the formula represents anthocyanin, Figure 5 (2) in the formula represents taurine, which proves that the organic composite material prepared in the present application does contain natural compounds such as anthocyanins and taurine that can relieve visual fatigue. When the eyeglass frame plate made of the organic composite material is used, it can volatilize active components that can relieve visual fatigue, thereby expanding the scope of action of the compound essential oil when the eyeglass frame is worn, and further enhancing the comfort of the user's eyes.

[0129] Experimental example

[0130] The organic composite material prepared in Example 1 was used as an object to conduct a method for detecting volatile active components in the sustained-release compound essential oil of the organic composite material. The instrument involved in the experiment was a tandem TGA-GC / MS. The particle size of the organic composite material used in the experiment was uniform and not larger than 20 meshes.

[0131] The specific steps are as follows:

[0132] Step 1: Fill the TGA with nitrogen, helium, or a mixture of any of the above gases and oxygen, or air, and set the gas flow rate to 20 mL / min;

[0133] Step 2, set the TGA to heat from the initial temperature state to any temperature T, where room temperature < T < 50 °C, and keep it at a constant temperature under the temperature condition of T, and set the temperature heating rate to 10 °C / min; the temperature heating rate refers to the temperature and running time of the gas sample collection of the GC / MS experiment, and the time of the gas sample collection of the adjacent GC / MS experiments is greater than the running time of the GC / MS experiment separation and detection;

[0134] Step 3: Collect the thermogravimetric curve and draw a thermogravimetric curve diagram. Figure 6 ;

[0135] Step 4, collecting gas samples for GC / MS experiments;

[0136] (1) The gas sample for GC / MS experiment is the gas generated by TGA operation at temperature T, which is collected;

[0137] (2) Setting GC / MS parameters, including chromatographic conditions and mass spectrometry conditions; the chromatographic conditions include: setting the chromatographic column to a weak polarity column, setting the carrier gas to helium, using constant flow mode to fill the carrier gas, and setting the carrier gas flow rate to 1.0 mL / min; setting the chromatographic temperature program, which is to heat to 30 °C and hold for 5 min, then heat to 280 °C at 10 °C / min and hold for 1 min-10 min; the mass spectrometry conditions are to set the transmission line temperature to 250 °C, set the EI ion source temperature to 250 °C, set the ionization energy to 50 eV, and set the scanning range to 10 amu-500 amu;

[0138] (3) Scan the sample, measure the peak area, and calculate the content of the active component of the Chinese medicine extract of the sample based on the average value of the peak area repeated three times;

[0139] (4) The particle samples were sealed and measured, and the measurements were repeated every 10 days. The gas chromatographic peak areas of the samples were recorded. The experiment lasted for 100 days. Figure 7 .

[0140] according to Figure 7 It can be obtained that the organic composite material prepared by Example 1 of the present application has the effect of slow-release compound essential oil, and after slow-release for 100 days, it still has a slow-release rate of more than 45%, which can achieve more efficient and lasting volatilization of compound essential oil. The preparation of eyeglass frame plate with this material can be achieved only by physical means, so the slow-release effect of the material itself will not be changed, and the prepared eyeglass frame plate has at least the same slow-release rate as the organic composite material. And the eyeglass frame made of the plate also has the same slow-release effect, which can effectively relieve the symptoms of eye fatigue and dryness when worn, and improve eye health.

[0141] In summary, the present application provides an organic composite material, a preparation method and its application, including using a gas phase extraction method to obtain a volatile active component that can relieve visual fatigue in a preferred Chinese medicine material, extracting a compound essential oil, and then placing carbon fiber in the compound essential oil, obtaining an organic composite material after impregnation, making the organic composite material into a spectacle frame plate, and finally using the plate to make a spectacle frame. The plate is formed by hot pressing and gluing a titanium zinc alloy plate as an intermediate layer and an organic composite material as an inner and outer layer to obtain a spectacle frame that can be used to slowly release a compound essential oil extracted from natural Chinese medicine and relieve visual fatigue. The spectacle frame has the advantages of being lightweight and low in cost. The prepared spectacle frame has excellent plasticity, stability, safety, impact resistance, and comfort, and contains a compound essential oil that can be slowly released when worn, effectively relieving eye fatigue and improving eye health.
