Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] In the figures, structurally similar elements are denoted by the same reference numerals.

[0052] The terms "first", "second", etc. in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0053] Please refer to Figure 1 ,in Figure 1 Flow chart of a preferred embodiment of the present invention.

[0054] The following is a preferred embodiment of a method for processing a water-based imitation leather paint slider and a corresponding slider structure provided by the present invention that can solve the above technical problems.

[0055] The preferred embodiment of the method for processing a water-based imitation leather paint slider provided by the present invention is: a method for processing a water-based imitation leather paint slider, and a slider structure made by the method. The following is a description of the detailed implementation of the present invention.

[0056] 1. Processing method of water-based imitation leather paint slider

[0057] 1. Hanging pull head 11.

[0058] S1: Hang the slider 11 on the mesh 12. The mesh 12 is designed with a frame 121, a crossbar 122 and a connector 123 to facilitate the fixing and hanging of the slider. Figure 2 Then, the screen 12 is mounted on the support frame 131 of the paint spraying device 13, as shown in FIG. Figure 2 - Figure 4 shown.

[0059] The slider 11 is mounted on a special mesh plate 12. The frame 121, cross bar 122 and connector 123 of the mesh plate 12 are designed so that the slider 11 can be firmly fixed on the mesh plate 12 to avoid movement or falling off during the spraying process, improve the spraying accuracy, and ensure the stability and uniformity of the slider 11 during the spraying process. The paint spraying device 13 includes a liquid collecting tank 133, a support frame 131, a rotating disc 132 and other components. The rotating disc 132 is rotatably connected to the support frame 131, and the mesh plate 12 is detachably arranged on the rotating disc 132 to facilitate subsequent spraying operations.

[0060] The spraying manipulator 134 can be used to precisely spray different surfaces of the slider 11. The liquid collecting tank 133 collects the paint liquid dripping after spraying. The use of the spraying manipulator 134 realizes precise spraying of different surfaces of the slider 11, improves the spraying efficiency and quality, and reduces the error of manual operation.

[0061] 2. Spraying and baking of epoxy resin paint.

[0062] S2: Spray epoxy resin paint on the surface of the slider to form a basic color layer.

[0063] S3: Put the slider sprayed with epoxy resin paint into the oven 14 for baking. Figure 7 The temperature of oven 14 is set at 120-150°C and the time is set at 80-100 minutes to ensure that the epoxy resin paint is completely cured to form a solid epoxy resin paint layer, improve the durability and adhesion of the coating on the surface of the slider, and prevent the coating from falling off or peeling off during use.

[0064] 3. Preparation and spraying of mid-coat varnish.

[0065] S4: Preparation of mid-coat varnish. Specifically comprising:

[0066] S41: Mix polyester resin, polyurea resin, polyurethane resin, butyl acetate, ethyl acetate, polyether-modified polydimethylsiloxane and polyester-modified polydimethylsiloxane to prepare a mid-coat varnish primer.

[0067] By weight percentage, the polyester resin is 50% to 60%, the polyurea resin is 10% to 20%, the polyurethane resin is 10% to 20%, the butyl acetate is 4% to 8%, the ethyl acetate is 4% to 8%, the polyether modified polydimethylsiloxane is 1% to 3%, and the polyester modified polydimethylsiloxane is 1% to 3%.

[0068] Among them, polyester resin is a saturated resin with long-term durability and stability. Polyester resin provides a solid foundation for the varnish base, ensuring the hardness, wear resistance and chemical resistance of the coating. Its light weight and high strength also help to improve the overall performance. Polyurea resin is a colorless or light yellow transparent liquid with high elasticity and toughness after curing; the coating made of polyurea resin has the properties of strong toughness, air insulation, water resistance, strong density, non-toxicity, curing odorlessness, and continuity. The addition of polyurea resin improves the elasticity and flexibility of the varnish base, enabling it to better adapt to the deformation of the substrate, while enhancing the water resistance and density of the coating. Polyurethane resin is a thermoplastic compound composed of diurethane. Polyurethane tree further enhances the strength and durability of the varnish base, while providing good impact resistance and aging resistance. Its light weight also helps to reduce the weight of the coating and improve the overall performance.

[0069] As a solvent, butyl acetate can ensure that the resin components are evenly dispersed during the spraying process, provide good leveling, and help the coating form a smooth and uniform surface. At the same time, its moderate evaporation rate makes it difficult for the coating to have pinholes or blistering during the drying process. Ethyl acetate also has good solubility and volatility, and has low toxicity, making it relatively safe to use. It can also be biodegraded and has little impact on the environment. As an auxiliary solvent, ethyl acetate works together with butyl acetate to further ensure the uniform dispersion of the resin components and the smoothness of the coating. At the same time, its environmental protection characteristics are also in line with the development trend of the modern coatings industry.

[0070] Polyether-modified polydimethylsiloxane improves the water repellency and antifouling properties of the varnish base, which helps to improve the durability and aesthetics of the coating. At the same time, its elastic characteristics also help to enhance the flexibility of the coating. Polyester-modified polydimethylsiloxane further improves the heat resistance and chemical resistance of the varnish base, enabling it to maintain stable performance in harsher environments.

[0071] In summary, the formula of the mid-coat varnish base material achieves the synergistic effect between various resins, solvents and modified siloxane components through reasonable proportions, making the varnish base material show excellent performance in hardness, flexibility, wear resistance, chemical resistance, heat resistance, etc. The solvent component ensures the uniform dispersion and good leveling of the resin component, making the construction process more convenient and efficient. Both butyl acetate and ethyl acetate have good environmental protection characteristics and meet the environmental protection requirements of the modern coatings industry.

[0072] S42: Add curing agent and pure water to the mid-coat varnish base material, and the ratio of the mid-coat varnish base material to the curing agent to the pure water is in the range of 4:1:2 to 4:1:4 to prepare the mid-coat varnish. The addition of curing agent and pure water not only saves costs compared to directly using the paint base material, but also enables the mid-coat varnish to be better cured to form a solid paint film, thereby improving the overall quality of the slider.

[0073] S5: Spray the intermediate varnish on the surface of the epoxy resin paint layer to enhance the adhesion and smoothness of the paint film. The spraying of the intermediate varnish enhances the adhesion and smoothness of the paint film and provides a better adhesion surface for the subsequent spraying of water-based imitation leather paint.

[0074] S6: Put the slider sprayed with the intermediate varnish into the oven 14 for baking. The temperature of the oven 14 is set at 120-150° C. and the baking time is 30 minutes to ensure that the intermediate varnish is completely cured to form an intermediate varnish layer.

[0075] 4. Preparation and spraying of water-based imitation leather paint.

[0076] S7: preparing water-based imitation leather paint, which specifically includes:

[0077] S71: Mix water-based polyurethane resin, water, silicon dioxide (precipitation method), DPM film former, polydimethylsiloxane dispersion, polyamide wax, polyether siloxane copolymer and amine neutralizer to prepare a water-based imitation leather paint base.

[0078] Among them, by weight percentage, water-based polyurethane resin 70% to 80%, water 10% to 20%, silicon dioxide 2% to 6%, DPM film former 2% to 6%, polydimethylsiloxane dispersion 0.5% to 3%, polyamide wax 0.5% to 3%, polyether siloxane copolymer 0.5% to 3%, amine neutralizer 0.1% to 1%. The water-based imitation leather paint makes the paint film have an imitation leather feel, which improves the appearance of the slider.

[0079] Among them, waterborne polyurethane resin is a polyurethane with water as a dispersion medium, which has the characteristics of high performance, high environmental protection, high hardness, high gloss, high water resistance, etc. As the main ingredient in the formula, waterborne polyurethane resin provides excellent flexibility and wear resistance for the base material, while ensuring the hardness and gloss of the coating. Its high environmental protection is also in line with the development trend of the modern coating industry. Water plays the role of a diluent in the formula, making the base material easier to construct and apply. At the same time, in the subsequent baking operation, the volatilization of water also helps to form a solid paint film. Silicon dioxide can improve the fluidity and anti-stickiness of the base material, while increasing the hardness and smoothness of the paint film. DPM film former is dipropylene glycol methyl ether (Di propy l ene Glyco lMethy l Ether). As an auxiliary agent for water-based coatings, DPM film former helps to reduce the emission of volatile organic compounds and meets environmental protection requirements. DPM film former can promote the plastic flow and elastic deformation of film-forming materials such as waterborne polyurethane resins, thereby improving its aggregation performance, so that the paint can form a good film layer in a wide range of construction temperature. This is crucial for water-based imitation leather paints because it ensures that the paint film can be cured evenly and stably under various conditions. The addition of DPM film formers improves the film properties of water-based imitation leather paints, helping to improve the gloss, flexibility and elasticity of the paint film, thus giving the paint film a leather-like feel.

[0080] Polydimethylsiloxane dispersion can significantly improve the waterproof performance and durability of the coating, while enhancing the wear resistance and chemical corrosion resistance of the coating. Polyamide wax is a coating additive that has the function of reducing surface tension, enhancing water resistance and durability. Polyamide wax can make the base material smoother and reduce the shrinkage and peeling of the coating. At the same time, it can also enhance the water resistance and durability of the paint film. Polyether siloxane copolymer can further improve the flexibility and weather resistance of the base material, making the coating more adaptable to various environmental conditions. Amine neutralizer is an additive that can adjust the pH of the coating. The addition of amine neutralizer helps to stabilize the pH value of the base material and ensure that the coating maintains stable performance during the construction process. At the same time, it can also promote the dispersion and dissolution of the coating, and improve the uniformity and adhesion of the coating.

[0081] In summary, the water-based imitation leather paint primer shows excellent performance in terms of flexibility, hardness, glossiness, water resistance, durability, etc. The materials in the formula have good fluidity and dispersibility, making the construction process more convenient and efficient. At the same time, the adhesion and film-forming properties of the primer are also significantly improved. The materials in the formula are all environmentally friendly materials, which meet the environmental protection requirements of the modern coatings industry.

[0082] S72: Add curing agent and pure water to the water-based imitation leather paint base material, and the ratio of the water-based imitation leather paint base material to the curing agent and pure water is in the range of 10:2:1 to 10:2:2 to prepare the water-based imitation leather paint. The addition of curing agent and pure water not only saves the cost of the paint base material, but also enables the water-based imitation leather paint to be better cured to form a paint film with an imitation leather texture, thereby improving the overall aesthetics and texture of the slider.

[0083] S8: spraying water-based imitation leather paint on the surface of the intermediate varnish layer to form a paint layer with an imitation leather texture.

[0084] S9: Put the slider sprayed with the water-based imitation leather paint into the oven 14 for baking. The temperature of the oven 14 is set at 100-130° C. and the baking time is 60-90 minutes to ensure that the water-based imitation leather paint is completely cured to form a water-based imitation leather paint layer.
