Description

Technical Field

[0001] This invention belongs to the field of membrane technology and relates to a manufacturing process and apparatus for a stain-resistant, scratch-resistant, and shiny household appliance film. Background Technology

[0002] The appearance design of home appliances is of great importance. Currently, to achieve the desired aesthetic texture, existing home appliance surfaces typically require a series of complex processing treatments on the steel plates. These processes include spraying, electroplating, and wire drawing, aiming to alter the visual and tactile characteristics of the steel to meet diverse consumer demands for aesthetics, durability, and brand style. To achieve the same effect, using a stain-resistant, scratch-resistant, and shiny appliance film can replicate the results of the previous processing methods. Therefore, designing a manufacturing process and apparatus for a stain-resistant, scratch-resistant, and shiny appliance film to solve the aforementioned problems is of significant necessity. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a manufacturing process and apparatus for a stain-resistant, scratch-resistant, and shiny appliance film.

[0004] To achieve the above objectives, the technical solution of the present invention is: a manufacturing process for a stain-resistant, scratch-resistant, and shiny appliance film, comprising the following specific steps: S1: Weigh diamond powder, curing agent, polishing oil, liquid polyurethane and diluent according to a specific ratio, mix the raw materials and stir continuously to prevent the heavy diamond powder from settling, and ensure that the diamond powder is evenly dispersed in the mixture to obtain the coating slurry. S2: Uniformly coat the prepared coating slurry onto the surface of the PET substrate, controlling the wet coating weight to be 28-32 grams per square meter and the viscosity of the coating slurry to be between 18 and 22, ensuring that 2000-3000 diamond powder particles are distributed on each square centimeter of PET surface after coating. S3: Dry and cure the coated PET to achieve a dry coating weight of 8-10 grams per square meter on the PET surface after curing. S4: Use glue to bond the PET layer and PVC layer together, with PET as the upper layer and PVC as the lower layer. Finally, apply an anti-scratch and anti-fouling treatment to the PET surface to obtain the finished anti-fouling, scratch-resistant, shiny appliance film.

[0005] The coating slurry comprises, by weight, 30-40 parts diamond powder, 6 parts curing agent, 8 parts polishing oil, 60 parts liquid polyurethane, and 10-16 parts diluent.

[0006] The coating slurry prepared by this ratio can maintain good dispersion of diamond powder while ensuring that the final coating has appropriate brilliance and structural strength. Combined with the subsequent scratch-resistant and stain-resistant treatment of the PET surface, the final appliance film, when applied to the steel plate surface of refrigerators and air conditioners, can not only give the steel plate surface a uniform and delicate shiny texture, but also resist scratches and stains in daily use for a long time, thus improving the decorative effect and durability of the appliance's appearance.

[0007] The device includes a frame, on which an upper pressure roller is horizontally rotatably mounted, the height of which is adjustable. Two lower coating rollers are also horizontally rotatably mounted on the frame, driven synchronously by a motor. A material trough is detachably mounted on the frame, and the upper pressure roller, lower coating rollers, and material trough are arranged sequentially from top to bottom. A base is located on the side of the frame, and a disc is rotatably connected to the base via a drive shaft, with the disc and drive shaft being fixedly connected.

One of the L-shaped components has a connecting ear connected to one end of the conveying pipe, and the other end of the conveying pipe is connected to the material trough. The other L-shaped component has a connecting ear connected to one end of the return pipe, and the other end of the return pipe is connected to the material trough. A conveying pump is installed on both the conveying pipe and the return pipe.

[0008] The base is rotatably mounted with pulley one and pulley two. Both pulley one and pulley two are fixedly connected to one end of an auxiliary block. The other end of the auxiliary block is fixedly connected to one end of an auxiliary shaft. The other end of the auxiliary shaft is connected to the two through a Z-shaped connecting block, and the Z-shaped connecting block and the auxiliary shaft are rotatably connected.

[0010] By adopting the above technical solution, the beneficial effects of the present invention are: The appliance film produced by this invention, by uniformly dispersing a corresponding proportion of diamond powder in the PET layer, gives the surface of the appliance steel plate a uniform and delicate shiny visual effect, greatly improving the appearance and texture of the appliance; at the same time, through the scratch-resistant and stain-resistant treatment of the PET surface, the appliance film can effectively resist scratch damage during daily use, is not easy to adhere to stains, and is more convenient to clean and maintain, effectively improving the durability of the appliance exterior layer, and meeting the appearance protection and decoration needs of commonly used appliances such as refrigerators and air conditioners for long-term use.

It does not require frequent manual stirring and replenishment, and can stably maintain continuous production, thereby improving production efficiency and the stability of finished product quality.

[0013] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0014] like Figure 1-3 As shown, the manufacturing process of this stain-resistant, scratch-resistant, and shiny appliance film includes the following specific steps: S1: Weigh diamond powder, curing agent, polishing oil, liquid polyurethane and diluent according to a specific ratio, mix the raw materials and stir continuously to prevent the heavy diamond powder from settling, and ensure that the diamond powder is evenly dispersed in the mixture to obtain the coating slurry. S2: Uniformly coat the prepared coating slurry onto the surface of the PET substrate, controlling the wet coating weight to be 28-32 grams per square meter and the viscosity of the coating slurry to be between 18 and 22, ensuring that 2000-3000 diamond powder particles are distributed on each square centimeter of PET surface after coating. S3: Dry and cure the coated PET to achieve a dry coating weight of 8-10 grams per square meter on the PET surface after curing. S4: Use adhesive to bond the PET layer and PVC layer together, with PET as the upper layer and PVC as the lower layer.

Figure 4 As shown.

[0015] The coating slurry comprises, by weight, 30-40 parts diamond powder, 6 parts curing agent, 8 parts polishing oil, 60 parts liquid polyurethane, and 10-16 parts diluent.

[0016] The coating slurry prepared by this ratio can maintain good dispersion of diamond powder while ensuring that the final coating has appropriate brilliance and structural strength. Combined with the subsequent scratch-resistant and stain-resistant treatment of the PET surface, the final appliance film, when applied to the steel plate surface of refrigerators and air conditioners, can not only give the steel plate surface a uniform and delicate shiny texture, but also resist scratches and stains in daily use for a long time, thus improving the decorative effect and durability of the appliance's appearance.

[0017] The device includes a frame 1, on which an upper pressure roller 6 is horizontally rotatably mounted, and the height of the upper pressure roller 6 is adjustable. Two lower paint rollers 5 are horizontally rotatably mounted on the frame 1, and the two lower paint rollers 5 are driven synchronously by a power motor 3. A material trough 4 is detachably mounted on the frame 1, and the upper pressure roller 6, lower paint rollers 5, and material trough 4 are arranged sequentially from top to bottom. A base 9 is arranged on the side of the frame 1, and a disc 11 is rotatably connected to the base 9 via a drive shaft 33. The disc 11 and the drive shaft 33 are fixedly connected. A material bucket 12 is fixed on the disc 11. Two guide posts 25 are also fixed on the base 9. The upper end of the guide posts 25 The device is fixedly connected to the mounting plate 27. A crossbar 15 is fixed on the mounting plate 27. A second power motor 16 is fixed on the crossbar 15. The output shaft of the second power motor 16 is fixedly connected to the agitator 13 through the coupling 14. A linkage sleeve 26 is slidably connected to the guide column 25. An L-shaped part 28 is fixed on the linkage sleeve 26. The connecting ear 28a of one L-shaped part 28 is connected to one end of the conveying pipe 7. The other end of the conveying pipe 7 is connected to the material trough 4. The connecting ear 28a of the other L-shaped part 28 is connected to one end of the return pipe 8. The other end of the return pipe 8 is connected to the material trough 4. A conveying pump is installed on both the conveying pipe 7 and the return pipe 8.

[0018] Puller 1 21 and pulley 23 are rotatably mounted on base 9. Puller 1 21 and pulley 23 are both fixedly connected to one end of auxiliary block 30. The other end of auxiliary block 30 is fixedly connected to one end of auxiliary shaft 31. The other end of auxiliary shaft 31 is connected to the two through Z-shaped connecting block 32, and Z-shaped connecting block 32 is rotatably connected to auxiliary shaft 31. Power motor 3 19 is fixed on base 9. The output shaft end of power motor is fixedly connected to pulley 3 10. Belt 1 20 is sleeved between pulley 3 10 and pulley 1 21. Worm gear 17 is fixed on transmission shaft 33. Worm 18, which cooperates with worm gear 17, is horizontally rotatably mounted on base 9. Puller 4 29 is also fixed on worm 18. Belt 2 22 is sleeved between pulley 4 29 and pulley 2 23. The middle part of auxiliary shaft 31 is rotatably connected to the lower end of power arm 24.

This adopts existing technology, and its circuits do not need to be redesigned.

[0020] During operation, the PET substrate passes between the upper pressure roller 6 and the lower coating roller 5. The coating slurry in the trough 4 adheres to the surface of the lower coating roller 5, and then the rotation of the lower coating roller 5 evenly transfers the slurry to the lower surface of the PET substrate. The upper pressure roller 6 can cooperate to press the substrate, ensuring uniform coating thickness. The coating slurry in the hopper 12 is continuously stirred by the stirring paddle 13 driven by the power motor 16 to prevent diamond powder from settling in the hopper 12. At the same time, the delivery pump transports the uniform slurry in the hopper 12 to the trough 4 through the delivery pipe 7. Excess slurry in the trough 4 is then transported back to the hopper 12 through the return pipe 8, realizing the circulation of the slurry and further preventing diamond powder from settling.

[0021] After the power motor 319 starts running, it drives pulley 310 to rotate. Pulley 310 drives pulley 21 to rotate through belt 20. At the same time, pulley 23 drives pulley 429 to rotate. Worm 18 rotates synchronously with pulley 429, and drives worm wheel 17 to rotate through meshing, thereby driving the material bucket 12 to rotate. On the other hand, the synchronous rotation of pulley 121 and pulley 23 drives the auxiliary blocks 30 connected to each of them to swing synchronously, thereby driving the two auxiliary shafts 31 to move synchronously. Finally, through the two power arms 24, the two linkage sleeves 26 are driven to rise and fall synchronously along the guide post 25, realizing the repeated rising and falling of the ends of the conveying pipe 7 and the return pipe 8 in the material bucket 12, improving the uniformity of material distribution in the material bucket 12, and making the process of material extraction by the feed pipe more stable and uniform.
