Description

Technical Field

[0001] The utility model relates to the technical field of color-coated coils, and more particularly to a scratch-resistant color-coated coil. Background Art

[0002] In existing technologies, the transportation process of color-coated coils faces challenges due to inconsistent inner diameters of the coils caused by different types of winding equipment. This also creates challenges in transportation and handling. Due to the lack of specialized lifting and transport equipment for specific inner diameters, the edges and corners of the color-coated coils are easily damaged during handling. This damage not only affects the appearance of the color-coated coils but can also negatively impact the subsequent use of the galvanized color-coated coils, such as reducing their corrosion resistance and affecting their processing quality.

[0003] Furthermore, existing color-coated coils have certain deficiencies in surface protection. Since they cannot effectively resist external cuts and scratches, the surfaces of these coils are easily scratched, resulting in unsightly scratches. This not only affects the appearance of the product and reduces the decorative effect, but also significantly shortens the service life of the coils. In industrial and daily use, this surface damage accelerates the wear of the material, thereby affecting its overall performance and durability, and resulting in unnecessary maintenance costs and replacement frequency for users.

[0004] Secondly, color-coated coils are widely used in many industries such as construction, furniture, and equipment manufacturing. Their surfaces are always exposed to the air, and dust and dirt will inevitably accumulate. These stains not only affect the appearance, but may also penetrate into the coating over time, further damaging the structure and performance of the coating.

[0005] In addition, the paint layer on the surface of existing color-coated coils often has excessively strong reflectivity. This strong reflection can easily cause visual fatigue under certain lighting conditions. Prolonged exposure to this highly reflective environment may burden the human visual system, affecting comfort and work efficiency. Utility Model Content

[0011] The utility model is further configured such that the oligomer is a polyurethane oligomer, which provides good bonding performance and mechanical strength, and enhances the adhesion between the coating and the substrate.

[0012] The utility model is further configured such that a self-cleaning coating is applied on the adhesive layer. The self-cleaning coating can be configured to be made of silicone resin, fluorocarbon resin, polyester resin and other materials, providing good pollution resistance and easy cleaning, reducing the adhesion of dirt and bacteria, and keeping the coating clean and hygienic.

[0013] The utility model is further configured such that the epoxy-modified polyurethane acrylate is a material modified by introducing epoxy groups into polyurethane acrylate, thereby providing good chemical resistance and heat resistance and enhancing the durability and stability of the coating.

[0014] The utility model is further configured such that the wear-resistant particles are configured as aluminum oxide, thereby enhancing the anti-scratch and anti-wear capabilities of the coating and extending the service life of the coating.

[0015] The utility model is further configured such that a suede mixed coating is applied on the self-cleaning coating to increase the texture and aesthetics of the coating while enhancing the adhesion and wear resistance of the coating.

[0016] The utility model is further configured such that the velvet mixed coating is configured as a primer epoxy resin mixed with velvet powder.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a scratch-resistant color-coated coil with the following beneficial effects:

[0019] 1. The support mechanism is cleverly designed. Through the coordinated action of the screw, center shaft, threaded sleeve, connecting rod, support rod and curved plate, effective support for the color-coated coil body is achieved. The rotation of the screw drives the connecting rod and support rod to extend outward through the cooperation of the thread and the threaded sleeve. Finally, the curved plate contacts and supports the inner side of the color-coated coil body, ensuring the stability of the color-coated coil during transportation and storage, and preventing damage caused by rolling or improper stacking of the coil. This support mechanism not only improves transportation efficiency, but also reduces the loss of color-coated coils during handling, ensuring the integrity and use effect of the product. In addition, the adjustability of the support mechanism enables it to adapt to color-coated coils of different sizes and inner diameters, improving the versatility and flexibility of the equipment.

[0020] 2. The anti-scratch hybrid layer is composed of polysiloxane, epoxy-modified polyurethane acrylate, alumina wear-resistant particles and polyurethane polymers. This layer effectively enhances the scratch resistance of the coating and provides additional protection through its unique chemical composition and wear-resistant properties.

[0021] 3. The self-cleaning coating can be made of silicone resin, fluorocarbon resin, polyester resin and other materials to give the coating hydrophobic and oleophobic properties and achieve self-cleaning function.

[0022] 4. The suede mixed coating is set to be a base-gloss epoxy resin mixed with velvet powder to increase the surface aesthetics and further self-cleaning ability. The glossiness of the low-gloss epoxy resin coating is lower than that of ordinary paint. When velvet powder is added to it, the surface coating formed will show a velvety texture. This texture effectively reduces the smoothness of the board surface and thus reduces the reflectivity of light on it. Such a design helps to reduce the visual discomfort caused by highly reflective surfaces, that is, visual fatigue. BRIEF DESCRIPTION OF THE DRAWINGS

Both sides of the color-coated coil body 1 are coated with an anti-scratch mixed layer, and the anti-scratch mixed layer comprises polysiloxane 8, epoxy-modified polyurethane acrylate 9, wear-resistant particles 10 and polymers 11. Polysiloxane 8, epoxy-modified polyurethane acrylate 9, wear-resistant particles 10 and polymers 11 are sequentially coated and arranged on both sides of the color-coated coil.

[0033] A first chemical coating 12 is applied between the color-coated coil body 1 and the anti-scratch mixed layer. The first chemical coating 12 is set as a galvanized purification layer to protect the underlying material from environmental factors and extend the service life. The galvanized purification layer can provide good corrosion resistance, protect the underlying material from environmental factors and extend the service life.

[0034] The oligomer 11 is a polyurethane oligomer 11, which provides good bonding performance and mechanical strength, and enhances the adhesion between the coating and the substrate. The oligomer 11 is a polyurethane oligomer 11, which provides good bonding performance and mechanical strength, and enhances the adhesion between the coating and the substrate.

[0035] A self-cleaning coating 13 is applied on the first chemical coating 12. The self-cleaning coating 13 can be made of silicone resin, fluorocarbon resin, or polyester resin. The design of the self-cleaning coating 13 can provide good pollution resistance and easy cleaning, reduce the adhesion of dirt and bacteria, and keep the coating clean and hygienic.

[0036] Epoxy-modified polyurethane acrylate 9 is a material modified by introducing epoxy groups into polyurethane acrylate. Epoxy-modified polyurethane acrylate 9 can provide good chemical resistance and heat resistance, and enhance the durability and stability of the coating.

[0037] The wear-resistant particles 10 are configured as aluminum oxide. The configuration of the wear-resistant particles 10 can provide good wear resistance, enhance the anti-scratch and anti-wear capabilities of the coating, and extend the service life of the coating.

[0038] In this embodiment, when the color-coated coil body 1 is fixed, the central shaft 3 is driven to rotate by an external transmission device, and the central shaft 3 drives the screw 2 to rotate. The screw 2 and the multiple sets of threaded sleeves 4 are threaded together to drive the multiple sets of threaded sleeves 4 to move along the threads of the screw 2. The threaded sleeves 4 push the connecting rod 5 to push the support rod 6 to extend outward, and the support rod 6 pushes the arc plate 7 to contact and support the inner side of the color-coated coil body 1, thereby completing the support of the color-coated coil body 1. The materials constituting the scratch-resistant mixed layer are polysiloxane 8, epoxy-modified polyurethane acrylate, aluminum oxide wear-resistant particles 10, and special polyurethane oligomers 11. In the initial stage, a first chemical coating 12 is evenly applied on the upper and lower surfaces of the substrate.

This layer effectively enhances the scratch resistance of the coating and provides additional protection due to its unique chemical composition and wear resistance. Next, an adhesive layer is applied on top of the anti-scratch mixed layer to strengthen the bonding between the layers. Finally, a self-cleaning coating 13 is applied on the adhesive layer to give the coating hydrophobic and oleophobic properties and realize the self-cleaning function.

The materials that constitute the scratch-resistant mixed layer are polysiloxane 8, epoxy-modified polyurethane acrylate, alumina wear-resistant particles 10 and special polyurethane Polymer 11, in the initial stage, a first chemical coating 12 is evenly applied on the upper and lower surfaces of the substrate. The main function of this coating is to improve the corrosion resistance of the substrate and the adhesion of subsequent coatings. Subsequently, an anti-scratch mixed layer is applied on top of the first chemical coating 12. This layer effectively enhances the scratch resistance of the coating and provides additional protection due to its unique chemical composition and wear resistance. Immediately afterwards, an adhesive layer is applied on top of the anti-scratch mixed layer to strengthen the bonding between the layers. Finally, a self-cleaning coating 13 is applied on the adhesive layer to give the coating hydrophobic and oleophobic properties and realize the self-cleaning function.

[0043] A velvet mixed coating 14 is applied on the self-cleaning coating 13 to increase the surface aesthetics and further self-cleaning ability. The glossiness of the low-gloss epoxy resin coating is lower than that of ordinary paint. When velvet powder is added thereto, the resulting surface coating will exhibit a velvety texture. This texture effectively reduces the smoothness of the board surface, thereby reducing the reflectivity of light thereon. Such a design helps to alleviate visual discomfort, i.e., visual fatigue, caused by highly reflective surfaces.
