Description

Technical Field

[0001] This application belongs to the field of printing plate technology, specifically a zinc plate with a self-cleaning coating. Background Technology

[0002] A zinc plate is a printing plate primarily used in the printing industry. Made of zinc, it possesses excellent printability and durability. Zinc plates are commonly used in letterpress printing, particularly for printing packaging materials, labels, and business cards. In letterpress printing, the image areas on the zinc plate are raised and transferred to paper or other materials by ink. Zinc plates can also be used to create other types of printing plates, such as offset and flexographic plates. Printing is achieved by transferring image information onto a zinc plate and then onto other printing plates.

[0003] For example, application CN2772813Y discloses a pre-coated photosensitive microcrystalline zinc plate, comprising a base zinc plate and a photosensitive layer coated on the surface of the base zinc plate. Its key feature is that a back paint layer is provided on the bottom surface of the base zinc plate, forming a three-layer structure. This back paint layer is composed of paint with acid, alkali, and high-temperature resistance properties. The photosensitive layer coated on the surface of the base zinc plate is a viscous liquid coating with ultraviolet light sensitivity, made from a highly photosensitive resin, combined with a photosensitive agent, pigment, filler powder, and a small amount of solvent, forming a dilute alkali developing photosensitive material. This pre-coated photosensitive microcrystalline zinc plate of the present invention has good surface quality, a long shelf life (more than one year), and also has advantages such as acid and alkali resistance and high-temperature resistance.

[0004] However, the zinc plate in this application does not have a self-cleaning function during use, which makes it inconvenient to reuse and thus affects the overall convenience of use. Utility Model Content

[0005] The purpose of this application is to provide a zinc plate with a self-cleaning coating in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: a zinc plate with a self-cleaning coating, comprising a zinc plate body, characterized in that: an anti-slip base plate is fixedly installed on the bottom of the zinc plate body.

[0007] The zinc plate body consists of a protective layer, a base zinc plate, a photosensitive layer, and a back paint layer. The protective layer includes a self-cleaning layer and a protective adhesive film layer.

[0008] By adopting the above technical solution, the protective film layer inside the protective layer can minimize the time for stains to adhere during use, thereby giving the protective layer a certain self-cleaning ability. This improves the convenience of using the overall device during subsequent cleaning of the zinc plate body. At the same time, the anti-slip base plate and anti-slip pad at the bottom of the zinc plate body can increase the friction between the zinc plate body and the placement surface, improving the anti-slip stability of the entire device during use.

[0009] In a preferred embodiment, the lower surface of the anti-slip base plate is provided with an anti-slip pad.

[0010] By adopting the above technical solution, the friction between the zinc plate body and the placement surface can be increased, thereby improving the anti-slip stability of the entire device during use.

[0011] In a preferred embodiment, the self-cleaning layer is a photocatalytic nanocomposite material coating.

[0012] By employing the above technical solution, the self-cleaning layer uses highly active chemical substances as precursors, which are mixed and hydrolyzed in the liquid phase to form a stable sol system. The sol is aged and polymerized to form a gel. This gel is then coated onto the substrate using a spraying process, followed by curing to obtain the final self-cleaning coating. A novel nitrogen-doped TiO2 / SWCNT photocatalytic nanocomposite material can be synthesized using tetraisopropoxide titanium and ammonia as precursors. This material can clean approximately 99% of dirt from the substrate surface.

[0013] The self-cleaning process of photocatalytic nanocomposite coatings on zinc plates is a complex process integrating light energy utilization, chemical reactions, and physical actions. First, photocatalytic materials in the coating, such as titanium dioxide nanoparticles, are excited under ultraviolet irradiation, generating electrons and holes. These charge carriers react with water molecules and oxygen on the surface, generating highly oxidizing hydroxyl radicals and superoxide ions. These active substances effectively decompose organic contaminants on the zinc plate surface, such as oil stains, dust, and microorganisms, converting them into harmless carbon dioxide and water. Simultaneously, the nanostructure of the coating surface endows it with superhydrophobicity, causing water droplets to form spherical shapes and easily roll off. This physical action not only prevents dirt adhesion but also carries away decomposed inorganic particles and residues as the water droplets roll off. The photocatalytic nanocomposite coating achieves chemical decomposition of dirt through photocatalytic reactions and physical cleaning through the superhydrophobicity of the nanostructure. The synergistic effect of these two processes allows the zinc plate surface to remain clean for a long time. This process not only extends the service life of the zinc plate but also reduces the need for cleaning and maintenance, resulting in significant environmental and economic benefits.

[0014] In a preferred embodiment, the protective film layer is an acrylic resin coating.

[0015] By adopting the above technical solutions, the overall protective performance of the zinc plate body is improved, and the safety and reliability during use are increased.

[0016] In a preferred embodiment, the photosensitive layer is a blue viscous liquid, synthesized from a highly photosensitive resin, and made into a high-precision, high-performance, dilute-alkali developing photosensitive material in combination with a photosensitive agent, pigment, filler powder and a small amount of solvent.

[0017] By adopting the above technical solution, a high-precision, high-performance, dilute-alkali developing photosensitive material is made by synthesizing a highly photosensitive resin, combined with a photosensitive agent, pigment, filler powder and a small amount of solvent.

[0018] In a preferred embodiment, the back coating layer is a ceramic coating.

[0019] By adopting the above technical solutions, the overall corrosion resistance and high temperature resistance have been improved.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0021] In this application, during use, the protective film layer inside the protective layer can minimize the time for stains to adhere, thereby giving the protective layer a certain self-cleaning ability. This improves the convenience of using the overall device during subsequent cleaning of the zinc plate body. At the same time, the anti-slip base plate and anti-slip pad at the bottom of the zinc plate body can increase the friction between the zinc plate body and the placement surface, improving the anti-slip stability of the entire device during use.

[0029] Example:

[0030] A zinc plate with a self-cleaning coating includes a zinc plate body 1, and an anti-slip base plate 2 is fixedly installed on the bottom of the zinc plate body 1.

[0031] The zinc plate body 1 consists of a protective layer 4, a base zinc plate 5, a photosensitive layer 6, and a back paint layer 7. The protective layer 4 includes a self-cleaning layer 8 and a protective film layer 9. The protective film layer 9 inside the protective layer 4 can minimize the time for stains to adhere, thus giving the protective layer 4 a certain self-cleaning ability. This improves the convenience of using the overall device during subsequent cleaning of the zinc plate body 1. At the same time, the anti-slip base plate 2 and anti-slip pad 3 at the bottom of the zinc plate body 1 can increase the friction between the zinc plate body 1 and the placement surface, improving the anti-slip stability of the entire device during use.

[0032] The lower surface of the anti-slip base plate 2 is provided with an anti-slip pad 3, which can increase the friction between the zinc plate body 1 and the placement surface, and improve the anti-slip stability of the entire device during use.

[0033] The self-cleaning layer 8 is a photocatalytic nanocomposite coating. It utilizes highly reactive chemicals as precursors, which are mixed and hydrolyzed in a liquid phase to form a stable sol system. The sol is aged and polymerized to form a gel. This gel is then coated onto a substrate using a spraying process, followed by curing to obtain the final self-cleaning coating. For example, novel nitrogen-doped TiO2 / SWCNT photocatalytic nanocomposite materials can be synthesized using tetraisopropoxide titanium (TTIP) and ammonia as precursors. This material can clean approximately 99% of dirt from the substrate surface.

[0034] The self-cleaning process of photocatalytic nanocomposite coatings on zinc plates is a complex process integrating light energy utilization, chemical reactions, and physical actions. First, photocatalytic materials in the coating, such as titanium dioxide nanoparticles, are excited under ultraviolet irradiation, generating electrons and holes. These charge carriers react with water molecules and oxygen on the surface, generating highly oxidizing hydroxyl radicals and superoxide ions. These active substances effectively decompose organic contaminants on the zinc plate surface, such as oil stains, dust, and microorganisms, converting them into harmless carbon dioxide and water. Simultaneously, the nanostructure of the coating surface endows it with superhydrophobicity, causing water droplets to form spherical shapes and easily roll off. This physical action not only prevents dirt adhesion but also carries away decomposed inorganic particles and residues as the water droplets roll off. The photocatalytic nanocomposite coating achieves chemical decomposition of dirt through photocatalytic reactions and physical cleaning through the superhydrophobicity of the nanostructure. The synergistic effect of these two processes allows the zinc plate surface to remain clean for a long time. This process not only extends the service life of the zinc plate but also reduces the need for cleaning and maintenance, resulting in significant environmental and economic benefits.

[0035] The protective film layer 9 is an acrylic resin coating, which improves the overall protection of the zinc plate body 1 and increases safety and reliability during use.

[0036] The photosensitive layer 6 is a blue viscous liquid, synthesized from highly photosensitive resin, combined with photosensitive agents, pigments, filler powder and a small amount of solvent to make a high-precision, high-performance, dilute alkali developing photosensitive material, which improves the overall printing effect.

[0037] The back coating layer 7 is a ceramic coating, which improves the overall corrosion resistance and high temperature resistance.

[0038] The implementation principle of the zinc plate with self-cleaning coating in this application is as follows: the protective film layer 9 set inside the protective layer 4 can minimize the time for stains to adhere, thereby giving the protective layer 4 a certain self-cleaning ability. In the subsequent cleaning process of the zinc plate body 1, the convenience of the overall device is improved. At the same time, the anti-slip base plate 2 and anti-slip pad 3 at the bottom of the zinc plate body 1 can increase the friction between the zinc plate body 1 and the placement surface, and improve the anti-slip stability of the entire device during use.
