[0002] Since glasses are worn for a long time, the comfort and durability of the glasses legs are particularly important. Currently, the materials of glasses legs mainly include metal, plate, ordinary plastic, wood, TR90, carbon fiber, etc., and the glasses legs made of these materials have their own advantages and disadvantages.

[0003] Carbon fiber temples are widely used due to their lightweight, corrosion-resistant, and non-deformable properties. They combine carbon fiber's strong tensile strength with its softness and workability, resulting in durability and a durable, long-lasting color. Compared to temples made from other materials, these temples offer many advantages and are therefore widely used. However, a drawback of carbon fiber is its brittleness.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0060] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0061] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0062] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0063] Since the use of carbon fiber materials in the prior art to make parts will cause brittleness and easy breakage, the present invention proposes a temple. This structure combines the lightweight and stability of high-strength carbon fiber with the high toughness advantage of high-model carbon fiber. By connecting parts with different characteristics of different materials, a carbon fiber composite temple with light weight and good anti-fracture toughness can be obtained.

[0064] Please refer to Figures 1 to 3 In an optional embodiment of the present invention, the temple 1 includes:

[0065] The main body 11 is a high-strength carbon fiber composite elastic member;

[0066] a tail end 12 connected to one end of the main body 11 and made of a high-model carbon fiber composite material; and

[0067] The connecting end 13 is connected to the other end of the main body 11 and is a high-strength carbon fiber composite rigid component.

[0068] In this embodiment, the temple 1 can be used for myopia glasses, plain glasses, sunglasses or AR glasses, etc., which are not limited here. It is understandable that the temple 1 is a long rod, and the connecting end 13, the main body 11 and the tail end 12 are connected in sequence in their respective extension directions to form the temple 1. The main body 11 is the intermediate structure of the temple 1, which serves to connect the tail end 12 and the connecting end 13. Its material is a high-strength carbon fiber composite material. The high-strength carbon fiber here refers to a carbon fiber with high strength (strength greater than 3.5GPa) and moderate modulus (modulus generally between 230GPa and 310GPa). For example, the high-strength carbon fiber is one of T300, T700, T800, and T1000. These types are usually measured by tensile strength index and have high tensile strength, thereby effectively preventing the risk of breakage. The main body 11 is set as an elastic member, that is, its shape can undergo certain elastic deformation, thereby facilitating appropriate adjustment of curvature within a certain range and improving wearing comfort.

[0069] The connecting end 13 is mainly used as a part for connecting the frame 2, so its strength requirement is also high. The connecting end 13 is set to be a high-strength carbon fiber composite rigid part. The higher tensile strength of the high-strength carbon fiber ensures its resistance to deformation and fracture, and is set as a rigid part to ensure its hardness and connection stability.

[0070] The tail end 12 is designed to fit the user's ear. To ensure its shape, it is designed to be a high-modulus carbon fiber composite material. The carbon content of the high-modulus carbon fiber must be greater than 98%, and the modulus must be at least 310GPa. For example, the high-modulus carbon fiber is one of M40, M55, M60, M40J, M55J, or M60J, which has good toughness and can effectively prevent deformation and fracture. The connecting end 13 and the tail end 12 are respectively connected to the two ends of the main body 11, thereby improving the overall structural stability of the temple 1. The tail end 12 adopts a streamlined design that conforms to ergonomics and fits smoothly against the ear, relieving ear pressure.

[0071] In the technical solution of the present invention, the temple 1 includes a main body 11, a tail end 12 and a connecting end 13. The main body 11 is a high-strength carbon fiber composite elastic part. The characteristics of the high-strength carbon fiber composite material, which is light, corrosion-resistant and high in strength, can be utilized to make the main body 11 lightweight and resistant to fracture. The shape design of the elastic part allows it to meet a certain elastic deformation, meet the demand for good toughness required by the temple 1, facilitate bending and adjustment, and improve wearing comfort. At the same time, the connecting end 13 is a high-strength carbon fiber composite rigid part, thereby meeting the requirements of lightweight, high strength and not easy to break. The tail end 12 is a high-modulus carbon fiber composite part, which can make use of the high modulus of high-modulus carbon fiber to have good resistance to deformation and fracture and good toughness. The temple 1 of this structure meets the corresponding performance requirements of each part by combining three different composite materials, which can make the temple 1 have good fracture resistance and toughness, and extend its service life.

[0072] In an optional embodiment, the high-strength carbon fiber composite elastic member includes a three-dimensional woven structure of high-strength carbon fibers and a thermosetting resin matrix that are stacked;

[0073] The high-strength carbon fiber composite material rigid component comprises a two-dimensional woven structure of high-strength carbon fibers and a thermosetting resin matrix that are stacked;

[0074] The high-modulus carbon fiber composite material part includes a two-dimensional woven structure of stacked high-modulus carbon fibers and a thermoplastic resin matrix.

[0075] In this embodiment, in order to improve the properties of carbon fiber, a resin matrix is ​​added to the carbon fiber material in the main body 11, tail end 12, and connecting end 13, thereby improving the toughness, impact resistance, and wear resistance of the structure. Specifically, the high-strength carbon fiber composite elastic member includes a three-dimensional woven structure of high-strength carbon fibers stacked together and a heat-set resin matrix. Because the three-dimensional woven structure has the advantage of being an integrated molding, it can have higher integrity and strength, effectively prevent breakage and delamination, and can achieve more complex structural shapes, making the structure more flexible. The three-dimensional woven structure can be optionally one of three-dimensional four-way, three-dimensional five-way, three-dimensional six-way, and three-dimensional seven-way to facilitate the production of the desired structural shape. The thermosetting resin matrix is ​​a resin that can solidify when heated. Optionally, the thermosetting resin matrix is ​​one of epoxy resin, phenolic resin, unsaturated polyester resin, and urea-formaldehyde resin. It has excellent mechanical properties and can improve the tensile strength and modulus of the high-strength carbon fibers.

[0076] At the same time, the high-strength carbon fiber composite rigid member serves as the connection end 13, including a two-dimensional woven structure of stacked high-strength carbon fibers and a thermosetting resin matrix. The type of high-strength carbon fibers is the same as the type range of the high-strength carbon fibers of the main body 11, and the two types can be the same or different. The carbon fibers here are of a two-dimensional woven structure. Because the two-dimensional woven structure has good integrity, high shear strength and strong impact resistance, it can significantly improve the strength and impact resistance of the connection end 13. Optionally, the two-dimensional woven structure is one of a plain, twill, or satin woven structure. For example, plain carbon fiber refers to a structural layer of a plain carbon fiber fabric, which is characterized by the warp and weft yarns being interwoven in an up-and-down pattern, that is, the warp and weft yarns are interlaced every other yarn, resulting in many interlacing points. The fabric is strong, wear-resistant, stiff, and smooth. In addition, the fiber bundles of this type of carbon fiber fabric have many bending points, and the elongation during tension is high, the tensile strength is high, and it is easier to handle when the structure is simple. The type range of the thermosetting resin matrix can also be the same as the range of the thermosetting resin matrix in the main body 11, and the specific type can be the same as or different from the thermosetting resin matrix type of the main body 11. The connecting section of this structure can effectively improve the tensile strength and impact resistance, ensure structural stability, have a certain hardness and rigidity, and effectively prevent deformation and fracture.

[0077] The high-model carbon fiber composite material part includes a two-dimensional woven structure of high-model carbon fibers and a thermoplastic resin matrix arranged in a stacked manner. The high-model carbon fibers herein refer to the above-mentioned embodiment, and the type of the two-dimensional woven structure also refers to the above-mentioned type range. The thermoplastic resin matrix is ​​one of polyethylene, polypropylene, polyvinyl chloride, and polystyrene, so as to have a good impregnation effect on the carbon fiber layer. Of course, the thermoplastic film layer is not limited to the above-mentioned types. The obtained high-model carbon fiber composite material part has a high modulus, good toughness, effectively prevents it from breaking, and has better heat resistance, corrosion resistance and structural stability.

[0078] Of course, the number of layers of the carbon fiber and resin matrix stacked above is not limited and can be set according to actual needs.

[0079] Introducing thermoplastic resin into carbon fiber can effectively improve the fracture toughness of the matrix and its composite materials. The molecular structure of thermoplastic resin composite materials is chain-like and flexible, so they have good toughness and excellent impact resistance. In addition, thermoplastic resin composite materials also have the advantages of no storage time and temperature restrictions, short molding cycle, simple molding process, etc., which effectively saves costs.

[0080] In an optional embodiment, the content of thermosetting resin in the high-strength carbon fiber composite elastic member is 30% to 60%;

[0081] And / or, the content of thermosetting resin in the high-strength carbon fiber composite material rigid part is 30% to 60%;

[0082] And / or, the thermoplastic resin content in the high modulus carbon fiber composite material part is 30% to 50%.

[0083] It is understandable that in order to ensure the toughness improvement effect of each component, the content of the resin matrix should not be too small. Of course, as the main strengthening structure foundation, the resin content of carbon fiber should not be too large. Therefore, the thermosetting resin content in the high-strength carbon fiber composite elastic part is set to 30% to 60%, for example, 40%, 45%, 50%, 55%, etc., so as to ensure the good impregnation effect and strength of the high-strength carbon fiber composite material. Similarly, the thermosetting resin content in the high-strength carbon fiber composite rigid part is set to 30% to 60%, such as 40%, 45%, 50%, 55%, etc., to ensure the impregnation effect and strength.

[0084] Please refer to Figure 1 In an optional embodiment, the high-strength carbon fiber composite elastic member is a positive wave component or a sine-cosine wave component;

[0085] And / or, the high-strength carbon fiber composite material rigid component is in a rectangular parallelepiped shape.

[0086] In this embodiment, to achieve high-strength elastic properties, the high-strength carbon fiber composite elastic member is configured as a positive wave member. Specifically, it comprises at least two flexures, each comprising a first and a second perpendicular section. The two flexures are connected end-to-end, allowing the main body 11 to undergo a certain degree of elastic deformation at the flexures, thereby enhancing wearing comfort. In other embodiments, the main body 11 may be configured as a sine-cosine wave member, with the flexures forming a curved shape, which also provides improved elastic properties.

[0087] On this basis, the high-strength carbon fiber composite material rigid part is set to a rectangular shape, that is, the connecting end 13 is a rectangular shape, and optionally, it is a rectangular plate, which is convenient to prepare, has good strength and anti-deformation ability, and improves structural stability.

[0088] Please combine Figure 1 and Figure 4 In an optional embodiment, a metal piece 14 is embedded in the end of the connecting end 13 away from the main body 11 , and the metal piece 14 is used to connect with the frame 2 .

[0089] In this embodiment, the temple 1 is connected to the frame 2 via the connecting end 13, thereby achieving a wearing function. It is understandable that the temple 1 and the frame 2 are usually hinged to achieve a storage effect, so the end of the connecting end 13 has a rotational matching structure connected to the frame 2. Here, a metal part 14 is embedded at the end of the connecting end 13, and the rotational matching with the frame 2 is achieved through the metal part 14. The good wear resistance and strength of the metal part 14 ensure the stability of the connection between the temple 1 and the frame 2, effectively preventing breakage. Optionally, the material of the metal part 14 is one or more of titanium-zinc alloy, copper-zinc alloy, and high-nickel alloy. The above-mentioned types of metal have good stability, corrosion resistance, good metallic gloss, and good fatigue resistance and fracture toughness, thereby improving the service life of the glasses.

[0090] In an optional embodiment, the metal part 14 is an embedded part and is partially exposed at the connecting end 13;

[0091] And / or, the end of the metal member 14 is disc-shaped and defines a hinge hole 141 .

[0092] In this embodiment, the metal part 14 is an embedded part. When preparing the connecting end 13, a part of the metal part 14 can be directly embedded in the carbon fiber laminate structure, and the two are connected through a hot pressing one-piece molding process. The other part of the metal part 14 is exposed at the connecting end 13, effectively ensuring the connection strength and stability between the connecting end 13 and the metal part 14.

[0093] As will be appreciated, to achieve rotational connection with the frame 2, the end of the metal member 14 is disc-shaped and has a hinge hole 141 formed therein. A fastener or a rotating shaft can be inserted through the hinge hole 141 and the hole in the frame 2 to achieve rotational engagement. The disc-shaped structure allows for smoother rotation. Of course, in other embodiments, the end of the metal member 14 can also be provided with a rotating shaft to directly rotate with the shaft hole in the frame 2.

[0094] Please refer to Figure 2 and Figure 3 In an optional embodiment, the tail end 12 and the main body 11 are connected by a snap connection or a plug connection;

[0095] And / or, the connection end 13 and the main body 11 are snap-connected or plug-connected.

[0096] To facilitate assembly, the tail end 12 and the main body 11 are connected by a snap-fit ​​mechanism. For example, a snap is formed on the end of the tail end 12 facing the main body 11, and a snap hole is formed on the end of the main body 11 facing the tail end 12. The snap-fit ​​mechanism and the snap hole connect to achieve a detachable connection between the tail end 12 and the main body 11. This is simple and convenient, improves assembly efficiency, facilitates replacement and maintenance, and saves costs. In other embodiments, the snap and the hole can also be a mortise and tenon structure, or a direct interference fit between the plug and the socket to achieve a detachable connection.

[0097] Similarly, a snap-fit ​​connection is provided between the connecting end 13 and the main body 11 to further facilitate the assembly of the temple 1. Here, the type of snap-fit ​​structure is not limited, for example, a snap-fit ​​structure or a mortise and tenon structure, or a plug-in connection is provided between the connecting end 13 and the main body 11.

[0098] Made of carbon fiber composite material, the temple 1 is lightweight, and its overall configuration adopts a streamlined design that conforms to ergonomics, fits smoothly against the ear, and relieves ear pressure. It is understandable that in the scenario where the temple 1 is used, the structural weight requirement is low, while the strength requirement is high. In the above embodiment, the size of the temple 1 should not be too large or too small, and its length is set to 13.5cm to 14.5cm, for example, 14cm, and the resin content is set to 30% to 50%, for example, 40%. When the shape of the connecting end 13 is set to be a rectangular parallelepiped, its thickness is 0.2 to 0.4mm, for example, 0.3mm, its length is 3 to 6cm, for example, 4cm or 5cm, and its width is 0.5 to 3cm, for example, 0.8cm, 1cm, 1.5cm, or 2cm. The thickness of the main body 11, the thickness of the tail end 12, and the thickness of the connecting end 13 are all the same, which are 0.2 to 0.4 mm. The length of the main body 11 is 5 to 8 cm, for example, 6 cm or 7 cm. The width and the width of the connecting end 13 are all in the range of 0.5 to 3 cm. The length of the tail end 12 is 5 to 6 cm. Thus, while ensuring structural strength, the temple 1 is made lighter and more comfortable to wear.

[0099] Please refer to Figure 5 The present invention also provides a method for preparing temples. The structure of the temples can refer to the temples of any of the above embodiments. The preparation method comprises:

[0100] Step S1: manufacturing a high-strength carbon fiber composite plate and a high-modulus carbon fiber composite plate through a hot pressing process;

[0101] Step S2: forming the high-strength carbon fiber composite plate and the high-modulus carbon fiber composite plate into a high-strength carbon fiber composite elastic member, a high-strength carbon fiber composite rigid member, and a high-modulus carbon fiber composite member through a compression molding process to obtain a main body, a connecting end, and a tail end, respectively;

[0102] Step S3: connecting the main body and the connecting end, and connecting the main body and the tail end to obtain the temples.

[0103] In this embodiment, since the high-strength carbon fiber composite elastic member of the main body is made of carbon fiber composite material, during preparation, step S1 requires the preparation of carbon fiber prepreg, that is, the high-strength carbon fiber composite plate and the high-model carbon fiber composite plate are respectively made by hot pressing process. The hot pressing process can be formed in one step without secondary processing. The prepared carbon fiber prepreg has a smooth surface, good density, and is durable, so that the structural strength of the high-strength carbon fiber composite plate is high and the toughness of the high-model carbon fiber composite plate is good. In step S2, since the main body, connecting section and tail end need to have corresponding shape characteristics, the prepared high-strength carbon fiber composite plate and the high-model carbon fiber composite plate are heated and pressurized through a mold to form the required structural shape, which is simple and convenient to manufacture. In step S3, the prepared main body, connecting end and tail end are prepared, and the main body is connected to the other two respectively. Here, the connection can be detachable, such as snap-on or plug-in, or fixed, such as adhesive, to obtain the temple structure.

[0104] Please refer to Figure 6 In an optional embodiment, step S1 of manufacturing a high-strength carbon fiber composite board and a high-model carbon fiber composite board by a hot pressing process includes:

[0105] Step S11: placing a laminate of high-strength carbon fiber and thermosetting resin film in a preheated press; and placing a laminate of high-modulus carbon fiber and thermoplastic resin film in a preheated press;

[0106] Step S12: performing the first decompression process several times, with a preset time interval between each two times;

[0107] Step S13: setting a first temperature, a first pressure, and a first pressurizing time, and then performing hot pressing to form a high-strength carbon fiber prepreg and a high-model carbon fiber prepreg, respectively, and then maintaining the pressure and cooling;

[0108] Step S14: stacking and pressing a plurality of the high-strength carbon fiber prepregs to form high-strength carbon fiber composite plates respectively through a hot pressing process; and alternately stacking and pressing a plurality of the high-model carbon fiber prepregs to form a high-model carbon fiber composite plate.

[0109] In this embodiment, in step S11, high-strength carbon fibers are stacked together with thermosetting resin films to form a physical mixed prepreg cloth, which is then placed in a preheated press as a preparatory step. In this process, the weaving structure and resin content of the high-strength carbon fibers need to be reasonably set so as to obtain the required rigidity and elasticity respectively as needed. For example, here, a three-dimensional weaving structure is used in the composite plate for high-strength carbon fiber composite elastic parts, while a two-dimensional weaving structure is used in the composite plate for high-strength carbon fiber composite rigid parts. Similarly, high-model carbon fibers are stacked with thermoplastic resin films and placed in another preheated press. Here, the high-model carbon fibers are also a two-dimensional weaving structure.

[0110] In step S12, the first decompression treatment is performed to ensure the subsequent pressurization effect. The whole process can be divided into multiple times and separated by a certain preset time. In step S13, various parameters for the hot pressing process are set again, such as the first temperature, the first pressure, and the first pressurization time, so as to be selectively set according to the material properties. Then hot pressing is performed. During the hot pressing process, the thermoplastic resin film will infiltrate the carbon fiber through flow, thereby forming a high-model carbon fiber prepreg. The thermosetting resin film can achieve better structural stability and improve the strength of the high-strength carbon fiber prepreg.

[0111] The thermosetting resin film's resin material properties can further improve the structural stability and corrosion resistance of the high-strength carbon fiber prepreg. The thermoplastic resin film's properties also enhance the fracture toughness of the high-model carbon fiber prepreg.

[0112] In step S14, the high-strength carbon fiber prepreg is stacked and laid, and a composite plate is formed by a hot pressing process. Here, the number of layers of the high-strength carbon fiber prepreg is 3 to 5 layers. For example, 3 layers, 4 layers or 5 layers, so as to have a better reinforcement effect without increasing the cost too much. Similarly, the high-model carbon fiber prepreg is also stacked and laid, and a composite plate is pressed by a hot pressing process. Here, the number of layers of the high-model carbon fiber prepreg is also not limited, for example, 3 layers, 4 layers or 5 layers.

[0113] In an optional embodiment, the first temperature range is 120-150° C., the first pressure range is 0.5-2 MPa, the first pressurization time is 20-60 min, the preset time is 10-20 s, and the number of depressurization times is 3-4 times.

[0114] In this embodiment, the number of depressurization times for the first time is set to 3 or 4 times, and the interval time between each two times is 10 to 20 seconds, for example, 10 seconds, 15 seconds, or 18 seconds, so as to obtain a better molding environment. The first temperature is 120 to 150°C, for example, 130°C, 140°C, etc., the first pressure is 0.5 to 2MPa, for example, 1MPa, 1.5MPa, etc., and the first pressurization time is 20 to 60 minutes, for example, 30 minutes, 40 minutes, or 50 minutes, etc., to ensure the hot pressing molding effect. At the same time, after the hot pressing is completed, the first pressure is kept unchanged during the cooling process of the mold, and the holding time is 40 to 60 minutes, for example, 40 minutes, 50 minutes, etc., so that the temperature is gradually cooled to room temperature, so as to obtain better structural stability and prevent internal structure cracking.

[0115] Please refer to Figure 7 In an optional embodiment, the step 2 of forming the high-strength carbon fiber composite plate and the high-model carbon fiber composite plate into a high-strength carbon fiber composite elastic member, a high-strength carbon fiber composite rigid member, and a high-model carbon fiber composite member by a compression molding process to obtain the main body, the connecting end, and the tail end, respectively, includes:

[0116] Step 21: Cut the high-strength carbon fiber composite plate and the high-modulus carbon fiber composite plate separately and place them in a preset metal mold;

[0117] Step 22: placing the metal mold on a preheated hot press for a second decompression process;

[0118] Step 23: setting a second temperature, a second pressure, and a second pressurizing time, and then performing hot pressing molding, maintaining the pressure and cooling down, to obtain a high-strength carbon fiber composite elastic part, a high-strength carbon fiber composite rigid part, and a high-model carbon fiber composite part.

[0119] In this embodiment, due to the particularity of the main body structure of the present application, a mold of a corresponding structure can be designed as needed. For example, when the main body is a positive wave component, the inner cavity structure of the mold is adapted thereto. In step S21, the prepared carbon fiber pre-composite plate is cut to conform to the approximate size of the desired product, so that it can be conveniently placed in the mold. The mold here selects a metal counter-mold to ensure high temperature resistance and anti-deformation effects. It is understandable that when the mold is made, there will usually be some oil stains or dirt remaining in the inner cavity, so before compression molding, it is cleaned with clean water or alkaline substances to remove the oil stains and impurities in the inner cavity. A release agent can then be applied to the inner cavity wall to facilitate subsequent demoulding. The high-strength carbon fiber composite plate and the high-model carbon fiber composite plate are placed in different molds respectively to form the corresponding required structural shapes.

[0120] In step S22, the mold is placed in a preheated hot press to ensure production efficiency and product stability, and then a second decompression process is performed to facilitate subsequent pressurization. In step S23, hot pressing parameters are set, such as a second temperature, a second pressure, and a second pressurization time, and hot pressing is performed. During this process, high-strength carbon fiber composite elastic parts, high-strength carbon fiber composite rigid parts, and high-model carbon fiber composite parts can be formed, and their internal structures can be further infiltrated and bonded to improve structural stability.

[0121] In an optional embodiment, the second decompression treatment is performed 3 to 4 times, with an interval of 10 to 20 seconds between each decompression treatment.

[0122] The second temperature is 130-180° C., the second pressure is 2-10 MPa, the second pressurizing time is 30-90 min, and the pressure holding time is 30-60 min.

[0123] In this embodiment, the second decompression is set to 3 or 4 times, and the interval between each two times is 10 to 20 seconds, for example, 10 seconds, 15 seconds, and 18 seconds, so as to obtain a better molding environment. The second temperature is 130 to 180°C, for example, 140°C, 150°C, 160°C, 170°C, etc. The second pressure is 2 to 10 MPa, for example, 3 MPa, 4 MPa, 5 MPa, 6 MPa, 7 MPa, 8 MPa, etc. The second pressurizing time is 30 to 90 minutes, for example, 40 minutes, 50 minutes, 60 minutes, 70 minutes, 80 minutes, etc., to ensure the molding effect. At the same time, after the heating and molding is completed, the second pressure is kept unchanged during the cooling process of the mold, and the holding time is 30 to 60 minutes, for example, 40 minutes, 50 minutes, etc., so that the temperature is gradually cooled to room temperature, so as to obtain better structural stability and prevent internal structure cracking.
