Description

Technical Field

[0001] The present invention relates to the technical field of composite rust-proof paper, and particularly to a paper-plastic glue-bonded composite rust-proof paper and a preparation system thereof. Background Art

[0002] ‌‌Rust-proof paper is a paper material used to prevent metals from rusting. Its base material is usually selected as packaging kraft paper, which is applicable to various metal materials and products. Currently, the base paper of rust-proof paper is mostly made by mixing bamboo pulp and wood pulp with lignosulfonate (to enhance moisture resistance). After the pulp is formed into a basic base paper through papermaking and calendering; however, the amount of bamboo pulp used in rust-proof paper is relatively large.

[0003] At present, the field of biomass conversion materials is booming, and the types of available materials are rich and diverse. Straw pulp is a very representative one. During the agricultural harvest season, there are often mountains of straw piled up in the fields. These seemingly useless agricultural wastes actually contain huge potential value.

[0004] If straw can be reasonably applied to the production process of the base paper of rust-proof paper, it is undoubtedly a very forward-looking and environmentally friendly innovative measure. In this way, the use ratio of traditional pulp in the production of rust-proof paper can be significantly reduced. From the perspective of resource recycling, this realizes the efficient recycling of straw materials, giving new life to straw that might otherwise be burned or discarded.

[0005] More importantly, this practice fully demonstrates its environmentally friendly characteristics. During the production process of traditional pulp, there are often problems of high energy consumption and environmental pollution. For example, a large amount of tree felling will damage the forest ecosystem, and the production of some chemical pulp will also generate pollutants such as wastewater and waste gas. In contrast, using straw pulp to make the base paper of rust-proof paper can effectively reduce the dependence on natural resources, reduce carbon emissions and pollutant emissions during the production process, contribute to environmental protection, and truly achieve the organic unity of resource conservation and environmental protection.

[0006] In addition, during the production of rust-proof paper, the first step is the treatment of the base paper, such as dust removal, and then the coating of the rust-proof liquid; currently, although the coating of the rust-proof liquid can be completed by a coating roller, due to the uneven amount of the rust-proof liquid transported to the coating roller by the application roller, the quality of the coating of the rust-proof liquid is not uniform, and subsequent treatment of the coated rust-proof liquid is required to make it evenly spread on the base paper, increasing the steps of the coating work and the investment in equipment; for this reason, the present application proposes a paper-plastic glue-bonded composite rust-proof paper and a preparation system thereof. Summary of the Invention

[0007] The object of the present invention is to solve the above technical problems, and to provide a paper-plastic glue-bonded composite rust-proof paper and its preparation system.

[0008] To achieve the above object, the present invention adopts the following technical solutions: A paper-plastic glue-bonded composite rust-proof paper, comprising a biomass conversion material substrate, a PE film, a PE / PP woven fabric layer, and an OPP film. A VCI rust-proof liquid is coated on the biomass conversion material substrate. A glue is coated between the PE / PP woven fabric layer and the OPP film. The biomass conversion material substrate, the PE film, the PE / PP woven fabric layer, and the OPP film are sequentially placed from bottom to top and pressed together to form a composite rust-proof paper.

[0009] Preferably, the biomass conversion material substrate is formed by mixing straw pulp and wood pulp and then undergoing papermaking and calendering.

The rust-proof liquid storage grooves are communicated with the connecting pipe through a plurality of air holes. When the coating roller rotates, the rust-proof liquid is coated on the biomass conversion material substrate in a strip shape. The hot air discharged from the air holes accelerates the separation of the rust-proof liquid from the rust-proof liquid storage grooves. The strip-shaped coating liquid spreads outwards and covers the entire biomass conversion material substrate due to gravity and the air discharged from the air holes.

[0011] Preferably, the guiding roller group includes two first driving rollers and two second driving rollers rotatably installed in the mounting frame.

The heat exchange mechanism includes a serpentine pipe located in the VCI rust inhibitor storage tank. Hoses are installed at both ends of the serpentine pipe. The two hoses are respectively connected to the air delivery pipe and the air outlet pipe.

[0016] Preferably, it further includes a dust removal mechanism. The dust removal mechanism includes a dust filtering box installed in the mounting frame.

[0017] Preferably, it further includes a transmission mechanism. The transmission mechanism includes a transmission shaft coaxially and fixedly connected to the rotating column. A linkage shaft is rotatably installed on the mounting frame. First synchronous pulleys are installed on the driving shaft and the linkage shaft.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Environmentally friendly and resource-saving: Using a mixture of straw pulp and wood pulp to produce the base material of the biomass conversion material, replacing part of the traditional pulp, significantly reducing the dependence on natural resources, especially reducing the felling of trees, which is beneficial to the protection of the forest ecosystem. The application of straw pulp realizes the efficient recycling of straw materials, avoids the burning or discarding of straw, reduces carbon emissions and pollutant emissions, and contributes to environmental protection.

[0019] 2. Improve the coating quality of the rust preventive liquid: The rust preventive liquid coating mechanism realizes the uniform coating of the rust preventive liquid through the design of the VCI rust preventive liquid storage tank, coating roller, air holes, etc. The design of the rotating plate in the VCI rust preventive liquid storage tank ensures the equal supply of the rust preventive liquid, controls the pressure between the VCI rust preventive liquid storage tank and the coating roller, and avoids the problem of uneven coating.

[0020] 3. The design of the rust preventive liquid storage groove and air holes on the coating roller enables the rust preventive liquid to be coated on the base material in a strip shape, and the hot air discharged through the air holes accelerates the separation of the rust preventive liquid from the storage groove. Using the action of gravity and air, the rust preventive liquid is evenly spread over the entire base material, improving the coating quality.

[0021] 4. Reduce subsequent processing steps: Since the rust preventive liquid is evenly coated, the subsequent steps of further processing the coated rust preventive liquid to make it evenly spread on the base paper are reduced, reducing the production complexity and equipment investment.

[0022] 5. Integration of dust removal and drying: The dust removal mechanism effectively removes the dust on the surface of the biomass conversion material base through the design of the dust filter box and suction pipe, ensuring the quality of the subsequent production of rust-proof paper. The drying mechanism air-dries the base material coated with the rust preventive liquid through the heated air, improving the production efficiency and ensuring the air-drying effect of the rust preventive liquid.

[0023] 6. Energy saving and temperature control: The heating mechanism heats the air through the design of the heating box and heating wire, and heats the rust preventive liquid through the heat exchange mechanism to keep it at a suitable temperature, ensuring that the fluidity of the rust preventive liquid meets the coating requirements. The temperature control mechanism ensures that the temperature of the air heated by the heating wire is within the appropriate range, avoiding energy waste and the volatilization of internal substances in the rust preventive liquid.

[0024] 7. Optimization of the transmission mechanism: The transmission mechanism realizes the linkage and transmission between components through the design of synchronous wheels, synchronous belts and gears, improving the production efficiency and stability. From the dust removal, rust preventive liquid coating, drying of the biomass conversion material base to the lamination of each layer of materials, the entire production process realizes automation and continuity, improving the production efficiency and product quality.

[0025] In summary, the present invention utilizes biomass conversion materials such as straw pulp to reduce dependence on natural resources, lower carbon emissions and pollution, and achieve resource recycling. At the same time, the rust preventive liquid coating mechanism is innovated to ensure uniform coating and reduce subsequent processing steps. The supporting mechanisms such as dust removal and drying improve the quality of the rust preventive paper, providing an environmentally friendly, efficient and high-quality solution for the production of rust preventive paper.

The biomass conversion material substrate, the PE film, the PE / PP woven fabric layer, and the OPP film are placed and pressed in sequence from bottom to top to form a composite rust-proof paper.

[0030] Among them, the biomass conversion material substrate is formed by mixing straw pulp and wood pulp through papermaking and calendering; by using biomass conversion materials instead of the original bamboo pulp, the use ratio of traditional pulp in the production of rust-proof paper can be significantly reduced. From the perspective of resource recycling, this realizes the efficient recycling of straw materials, gives new life to straw that might otherwise be burned or discarded, and using straw pulp to make the base paper of rust-proof paper can effectively reduce the dependence on natural resources, reduce carbon emissions and pollutant emissions during the production process, contribute to environmental protection, and truly achieve the organic unity of resource conservation and environmental protection.

[0031] The present invention also discloses a preparation system for a paper-plastic adhesive composite rust-proof paper, which includes a base 1. An installation frame 2 is installed on the base 1, and a guiding roller group is installed on the installation frame 2. The guiding roller group includes two first driving rollers 3 and two second driving rollers 13 rotatably installed in the installation frame 2. The two second driving rollers 13 are located below the two first driving rollers 3 and are inclined outward. The biomass conversion material base material is wound around the first driving rollers 3 and the second driving rollers 13.

[0032] A PE film composite pressing mechanism 4, a PE / PP woven fabric laminating mechanism 5, and an OPP film composite pressing mechanism 6 are sequentially installed in the installation frame 2 from left to right. The biomass conversion material base material is wound around the guiding roller group, and the biomass conversion material base material passes through the PE film composite pressing mechanism 4, the PE / PP woven fabric laminating mechanism 5, and the OPP film composite pressing mechanism 6 in sequence to be pressed to form a composite rust-proof paper.

[0033] A VCI rust-proof liquid coating mechanism for treating the biomass conversion material base material is installed in the installation frame 2. The rust-proof liquid coating mechanism includes a VCI rust-proof liquid storage tank 7 installed in the installation frame 2. A circular groove 36 is provided in the VCI rust-proof liquid storage tank 7. A rotating column 37 rotatably provided and coaxial with the circular groove 36 penetrates through the VCI rust-proof liquid storage tank 7. A rotating plate 38 slidably abutted against the inner wall of the circular groove 36 is fixed on the rotating column 37. The rotating plates 38 are circumferentially arranged in an array outside the rotating column 37. The same-volume VCI rust-proof liquid feeding spaces are formed between adjacent two rotating plates 38 and the circular groove 36, and an equal amount of VCI rust-proof liquid can be provided at the lower end of the VCI rust-proof liquid storage tank 7.

[0034] The bottom of the VCI rust-proof liquid storage tank 7 is in a converging and gutter-shaped setting. A connecting pipe 40 is rotatably connected in the VCI rust-proof liquid storage tank 7. A coating roller 31 fixedly connected thereto is sleeved on the connecting pipe 40. The coating roller 31 is located at the lower end inside the VCI rust-proof liquid storage tank 7 and is slidably abutted. Among them, a plurality of stoppers are fixed on the inner wall of the VCI rust-proof liquid storage tank 7. The stoppers are arranged in cooperation with the rust-proof liquid storage grooves 41, so that one side of the coating roller 31 can be blocked, and it can only be discharged from the space between the other side and the VCI rust-proof liquid storage tank 7.

[0035] Part of the coating roller 31 is located below the VCI rust-proof liquid storage tank 7. A plurality of rust-proof liquid storage grooves 41 in an annular shape are provided on the outside of the coating roller 31. The rust-proof liquid storage grooves 41 are communicated with the connecting pipe 40 through a plurality of air holes 39. When the coating roller 31 rotates, the rust-proof liquid is coated on the biomass conversion material base material in a strip shape. The hot air discharged from the air holes 39 accelerates the separation of the rust-proof liquid from the rust-proof liquid storage grooves 41. The strip-shaped coating liquid spreads outward and covers the entire biomass conversion material base material due to gravity and the air discharged from the air holes 39.

[0036] It further includes a gas supply mechanism for supplying gas to the air holes 39. The gas supply mechanism includes a drive shaft 17 fixedly connected coaxially with the first driving roller 3. A circular plate 15 is fixed on the drive shaft 17. A connecting rod 27 is eccentrically hinged to the circular plate 15. A piston cylinder 16 is installed on the mounting frame 2. A moving piston 26 is slidably connected in the piston cylinder 16. The connecting rod 27 is hinged to the moving piston 26. An exhaust pipe 24 is installed at the upper end of the piston cylinder 16. A first one-way valve 28 is installed on the exhaust pipe 24. The first one-way valve 28 only allows air to be transported into the exhaust pipe 24 through the piston cylinder 16.

[0037] A rotating pipe 20 is rotatably connected to the exhaust pipe 24. The rotating pipe 20 is fixedly connected to the connecting pipe 40. An intake pipe 25 is installed on the piston cylinder 16. A second one-way valve 29 is installed on the intake pipe 25. The second one-way valve 29 only allows air to enter the piston cylinder 16 through the intake pipe 25.

[0038] It further includes a heat supply mechanism for delivering hot air to the air holes 39. The heat supply mechanism includes a heating box 8 installed in the mounting frame 2. An electric heating wire 32 is installed in the heating box 8. The intake pipe 25 is connected to the heating box 8. Among them, a temperature control mechanism is installed in the heating box 8, so that the temperature of the air heated by the electric heating wire 32 is between 25 and 35 degrees Celsius.

[0039] It further includes a drying mechanism. The drying mechanism includes an air delivery pipe 12 connected to the heating box 8. The other end of the air delivery pipe 12 is provided with an air outlet pipe 10. An exhaust box 14 is installed at the lower end of the air outlet pipe 10. A blower is installed in the exhaust box 14. The air inlet end of the blower is connected to the air outlet pipe 10. A plurality of exhaust slots 33 opposite to the air outlet end of the blower are provided through the bottom of the exhaust box 14. After the rust preventive liquid is coated on the biomass conversion material substrate, the heated air can dry the coated rust preventive liquid.

[0040] It further includes a heat exchange mechanism for heating the rust preventive liquid in the VCI rust preventive liquid storage tank 7. The heat exchange mechanism includes a serpentine pipe 34 located in the VCI rust preventive liquid storage tank 7. Hoses 35 are installed at both ends of the serpentine pipe 34. The two hoses 35 are respectively connected to the air delivery pipe 12 and the air outlet pipe 10. The serpentine pipe 34 through which hot air passes can heat the rust preventive liquid to keep it at a suitable temperature to ensure that the fluidity of the rust preventive liquid meets the coating requirements.

[0041] It further includes a dust removal mechanism. The dust removal mechanism includes a dust filtering box 9 installed in the mounting frame 2. The dust filtering box 9 is connected to the heating box 8 through a pipe 11. A dust filtering plate 42 is installed in the dust filtering box 9. A dust suction pipe 30 located below the dust filtering plate 42 is installed on one side of the dust filtering box 9. The dust suction pipe 30 is arranged opposite to the biomass conversion material substrate, and can remove dust from the biomass conversion material substrate to ensure the quality of the subsequent production of rust proof paper.

[0042] It further includes a transmission mechanism, which includes a transmission shaft 23 coaxially and fixedly connected to the rotating column 37. A linkage shaft 43 is rotatably installed on the mounting bracket 2. First synchronous pulleys 18 are installed on both the drive shaft 17 and the linkage shaft 43. The two first synchronous pulleys 18 are connected by a first synchronous belt 19. Gears 44 are installed on both the linkage shaft 43 and the rotating tube 20. The two gears 44 are meshed with each other. Second synchronous pulleys 21 are installed on both the rotating tube 20 and the transmission shaft 23. The two second synchronous pulleys 21 are connected by a second synchronous belt 22.

[0043] A motor is installed in the present invention. The motor is installed on the mounting bracket 2 and is connected to the first transmission roller 3. The rotation of the first transmission roller 3 can drive the drive shaft 17 to rotate and supply power to the blower at the same time.

[0044] The production process of the rust-proof paper is as follows: The biomass conversion material base material such as Figure 1 is wound around the first transmission roller 3 and the second transmission roller 13 as shown. When the blower works, the external air enters the dust filtering box 9 through the dust suction pipe 30, and then successively passes through the pipeline 11, the heating box 8, the air supply pipe 12, the hose 35, the serpentine pipe 34, and the air outlet pipe 10 and enters the exhaust box 14.

[0045] When the air enters the dust filtering box 9 through the dust suction pipe 30, the nozzle of the dust suction pipe 30 is in a negative pressure state at this time, so that the dust on the surface of the biomass conversion material base material can be removed, that is, the side to be coated with rust-proof water is dusted, reducing the influence of subsequent dust and the like on the coating of rust-proof water and subsequent pressing, and also ensuring the quality of the production of rust-proof paper.

[0046] When the air and dust pass through the dust filtering box 9, the dust in the air can be filtered through the dust filtering plate 42, that is, the clean air enters the heating box 8 through the pipeline 11, and the air can be heated through the electric heating wire 32; the heated air enters the serpentine pipe 34 through the air supply pipe 12 and the hose 35, and the rust-proof liquid can be heat-exchanged and heated through the serpentine pipe 34 so that it is at a temperature of about 30 °C. At this time, the fluidity of the rust-proof liquid is good and the internal substances will not volatilize, which is beneficial to the subsequent coating work.

[0047] Then, the air enters the exhaust box 14 through the air outlet pipe 10 and is discharged through the exhaust groove 33.

[0048] Among them, the rotation of the first driving roller 3 drives the rotation of the driving shaft 17. When the driving shaft 17 rotates, the linkage shaft 43 rotates under the cooperation of the first synchronous pulley 18 and the first synchronous belt 19. Under the transmission of the two gears 44, the rotating pipe 20 rotates in the opposite direction to the rotation direction of the linkage shaft 43. Under the transmission of the second synchronous belt 22 and the second synchronous pulley 21, the transmission shaft 23 rotates. The rotation of the transmission shaft 23 drives the rotation of the rotating column 37, and the rotation of the rotating column 37 drives the rotation of the rotating plate 38. Cooperating with the circular groove 36, when the rotating plate 38 rotates, the rust preventive liquid in the VCI rust preventive liquid storage tank 7 can be evenly transported to the lower part of the VCI rust preventive liquid storage tank 7 and fall between the VCI rust preventive liquid storage tank 7 and the coating roller 31. In this way, it is avoided that the pressure between the coating roller 31 and the VCI rust preventive liquid storage tank 7 is too large, resulting in the rapid discharge of the rust preventive liquid. In this way, the pressure between the rust preventive liquid and the coating roller 31 and the VCI rust preventive liquid storage tank 7 can be effectively controlled, and the coating work can be carried out more stably and effectively.

[0049] The rust preventive liquid accumulates in the rust preventive liquid storage tank 41. When the coating roller 31 rotates against the substrate, the rust preventive liquid can be discharged through the rust preventive liquid storage tank 41, and the rust preventive liquid is rolled on the substrate in a strip shape. Due to the gravity of the rust preventive liquid, the rust preventive liquid spreads outwards, so that the rust preventive liquid is coated on the substrate.

[0050] The rotation of the driving shaft 17 drives the rotation of the circular plate 15. The rotation of the circular plate 15 drives the movement of the connecting rod 27. The movement of the connecting rod 27 drives the up and down movement of the moving piston 26. When the moving piston 26 moves downwards, the hot air in the heating box 8 can be inhaled into the piston cylinder 16 through the air inlet pipe 25. When the moving piston 26 moves upwards, the hot air in the piston cylinder 16 can be transported to the rotating pipe 20 through the exhaust pipe 24 and finally discharged through the plurality of air holes 39; the air holes 39 located in the VCI rust preventive liquid storage tank 7 are not easily discharged due to the pressure of the rust preventive liquid, while the air holes 39 in other positions are under less pressure and can discharge air. In this way, the rust preventive liquid in the rust preventive liquid storage tank 41 can be more completely coated on the substrate, ensuring that the rust preventive liquid coated on the substrate is more uniform.

[0051] When there is no rust preventive liquid in the rust preventive liquid storage tank 41, the air discharged from the air holes 39 can blow towards the rust preventive liquid, making the dispersion effect of the rust preventive liquid better, ensuring the quality of coating the substrate, and thus ensuring the quality of the subsequent production of rust proof paper.

[0052] When the substrate coated with the rust preventive liquid moves to the exhaust box 14, the hot air is discharged through the exhaust groove 33 and blows towards the substrate. In this way, the substrate can be air-dried for subsequent pressing work. In addition, a gradient drying device can be set up to gradually increase the drying temperature of the substrate to ensure the drying quality.

[0053] The dried base material passes through the PE film composite laminating mechanism 4, and through the unwinding and laminating of the PE film, the PE film composite laminating work is achieved; similarly, through the PE / PP woven fabric laminating mechanism 5 and the OPP film composite laminating mechanism 6, the lamination of the PE / PP woven fabric and the composite lamination of the OPP film are achieved, thus completing the production of the rust-proof paper.

[0054] After the production of the rust-proof paper, trimming and winding can be carried out.

[0055] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
