[0002] The PU graphene waterproof and moisture-permeable membrane is a film with waterproof, moisture-permeable, oil-resistant and ultraviolet-resistant properties. It is usually prepared by polyurethane (PU) and graphene together. The application fields of the PU graphene waterproof and moisture-permeable membrane are gradually expanding. In addition to the initial clothing field, it is also applied to multiple industries such as medical, electronic and construction.

[0003] In the forming process of the existing PU graphene waterproof and moisture-permeable membrane, due to factors such as uneven distribution of raw materials, coating process problems or equipment precision, the thickness of the membrane may be uneven, which may further cause unstable product performance and reduced durability.

[0012] Advantages of the present utility model:

[0013] In the present utility model, the graphene film is limited by adjusting the distance between the limit air cylinder and the scraping plate according to the required thickness of the graphene film at the lower end of the scraping plate, so as to accurately control the thickness of the graphene, thereby meeting the different requirements of various specific applications for the material properties. When the graphene film passes through the lower end of the scraping plate, under the action of the return spring, the graphene solution sprayed on the graphene base film is scraped flat, which can ensure its surface flatness and improve the performance and reliability of the device. The graphene base film is placed on the graphene film base layer placement plate and guided by the alignment plate to prevent deviation. When the graphene base film is pushed onto the conveyor belt, the suction pump makes the air suction plate form an adsorption force through the air pipe to fix the graphene base film. Through suction fixation, the object can be quickly adsorbed and fixed at the required position, improving work efficiency and leaving no marks on the surface of the graphene object, ensuring the surface integrity and purity of the graphene. Under the conveyance of the conveyor belt, the graphene base fixed on the air suction plate is conveyed to the lower end of the high-temperature adjustment cover, and the graphene is dried by the heating tubes. The high-temperature environment helps to remove impurities such as moisture adsorbed on the surface of the graphene, improve the purity of the graphene, and at the same time helps to improve the adhesion between the graphene and the substrate or other materials, thereby enhancing the performance of the composite material.

[0022] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0024] Such as Figures 1-5As shown in the figure, a multifunctional PU graphene waterproof and moisture-permeable film preparation machine includes: an equipment base 1, on which an equipment protective cover 3 is fixedly installed. On both sides of the upper end of the equipment base 1 inside the equipment protective cover 3, equipment support plates 101 are fixedly installed. On the equipment support plates 101, a support frame 105 is fixedly installed. On the support frame 105, a limit cylinder 106 is fixedly installed. Below the limit cylinder 106, there is a scraper 107. The scraper 107 is slidably connected to a guide post 109. A return spring 108 is sleeved on the guide post 109. The upper and lower ends of the return spring 108 are respectively fixedly installed on the support frame 105 and the scraper 107.

[0025] In this way, the graphene film is limited by adjusting the distance between the limit cylinder 106 and the scraper 107 according to the required thickness of the graphene film at the lower end of the scraper 107, so that the thickness of the graphene can be accurately controlled, thus meeting the different requirements of various specific applications for the material properties. When the graphene film passes through the lower end of the scraper 107, under the action of the return spring 108, the graphene solution sprayed on the graphene base film is scraped flat, and thus the surface flatness can be ensured, improving the performance and reliability of the device.

[0026] As an alternative implementation, as Figures 1-5 shown, on one side of the support frame 105, there is a telescopic cylinder 102. The telescopic cylinder 102 is fixedly installed on the equipment support plate 101. The output end of the equipment support plate 101 is fixedly connected to a graphene solution placement box 104. At the lower end of the graphene solution placement box 104, a number of uniformly distributed nozzles 103 are fixedly connected.

[0027] In this way, the distance between the nozzle 103 and the graphene base film is adjusted by the telescopic cylinder 102, and then the graphene spraying amount is adjusted by the spraying distance.

[0028] As an alternative implementation, as Figures 1-5 shown, a guide plate 110 is fixedly installed inside the equipment support plate 101. A conveyor belt 116 is slidably arranged on the guide plate 110. The conveyor belt 116 is fixedly installed on a conveyor belt support frame 113 at the upper end of the equipment base 1. At one end of the conveyor belt 116 away from the graphene solution placement box 104, there is a graphene film base placement plate 2. The graphene film base placement plate 2 is fixedly installed on the equipment base 1. On both sides of the graphene film base placement plate 2, alignment plates 201 are fixedly installed. A number of uniformly distributed air suction plates 114 are fixedly installed on the conveyor belt 116. Both ends of the air suction plates 114 are fixedly connected to air pipes 112 for air extraction.

[0029] In this way, the graphene base film is placed on the graphene film base placement plate 2, and the alignment plate 201 guides it to prevent deviation. When the graphene base film is pushed onto the conveyor belt 116, the suction pump forms an adsorption force through the air pipe 112 to fix the graphene base film on the suction plate 114. By suction fixation, the object can be quickly adsorbed and fixed at the required position, improving work efficiency and leaving no marks on the surface of the graphene object, ensuring the surface integrity and purity of the graphene.

[0030] As an alternative embodiment, as Figures 1-5 shown, a high-temperature adjustment cover 111 is provided at the upper end of the suction plate 114. The high-temperature adjustment cover 111 is fixedly connected to the guide plate 110, and a number of uniformly distributed heating tubes 115 are fixedly installed inside the high-temperature adjustment cover 111.

[0031] In this way, under the conveyance of the conveyor belt 116, the graphene base fixed on the suction plate 114 is conveyed to the lower end of the high-temperature adjustment cover 111, and the graphene is dried by the heating tubes 115. The high-temperature environment helps to remove impurities such as moisture adsorbed on the surface of the graphene, improving the purity of the graphene. At the same time, it helps to improve the adhesion between the graphene and the substrate or other materials, thereby enhancing the performance of the composite material.

[0032] In this embodiment, as Figures 1-5 shown, the graphene base film is placed on the graphene film base placement plate 2, and the alignment plate 201 guides it to prevent deviation. When the graphene base film is pushed onto the conveyor belt 116, the suction pump forms an adsorption force through the air pipe 112 to fix the graphene base film on the suction plate 114. By suction fixation, the object can be quickly adsorbed and fixed at the required position, improving work efficiency and leaving no marks on the surface of the graphene object, ensuring the surface integrity and purity of the graphene. The distance between the nozzle 103 and the graphene base film is adjusted by the telescopic cylinder 102, and then the spraying amount of graphene is adjusted by the spraying distance. The graphene film is limited by adjusting the distance between the limit cylinder 106 and the scraping plate 107 according to the required thickness of the graphene film at the lower end of the scraping plate 107, and the thickness of the graphene can be accurately controlled, so as to meet the different requirements of various specific applications for the material performance. When the graphene film passes through the lower end of the scraping plate 107, under the action of the return spring 108, the graphene solution sprayed on the graphene base film is scraped flat, which can ensure its surface flatness and improve the performance and reliability of the device. Under the conveyance of the conveyor belt 116, the graphene base fixed on the suction plate 114 is conveyed to the lower end of the high-temperature adjustment cover 111, and the graphene is dried by the heating tubes 115. The high-temperature environment helps to remove impurities such as moisture adsorbed on the surface of the graphene, improving the purity of the graphene. At the same time, it helps to improve the adhesion between the graphene and the substrate or other materials, thereby enhancing the performance of the composite material.
