Description

TECHNICAL FIELD

[0001] The utility model relates to the field of reverse surface oil, concretely is a reverse surface oil coating structure. BACKGROUND

[0002] Reverse surface oil, as a kind of process material that utilizes ultraviolet light curing reaction for surface treatment, its importance is self-evident in the printing industry, especially for the offset printing field that pursues extreme high precision and excellent quality, it is an indispensable key element. In the complex and delicate printing process, reverse surface oil is carefully designed and scientifically placed on the connecting oil seat of the printing machine, and the careful selection of this position aims to maximize the synergistic effect between the reverse surface oil and the base oil (also known as the base ink), creating a unique and eye-catching reverse UV process effect. The application of reverse surface oil not only innovates the printing technology, but also makes a leap in the printing quality and artistic expression. It realizes the perfect fusion of color and luster through close cooperation with the base oil, giving the printed matter more rich levels and visual impact. At the same time, the unique luster effect exhibited by reverse surface oil is like a dazzling dress for the printed matter, making it stand out among many printed matters and become a beautiful landscape.

[0003] Common reverse surface oil, as the outstanding performer in the field of printed matter surface treatment, has outstanding performance. On the surface of the printed matter, reverse surface oil can form a layer of bright high-gloss effect. This gloss not only significantly improves the overall texture of the printed matter, making it more delicate and smooth, but also gives the printed matter more rich visual levels and stereoscopic effect. This luster effect, like a bright pearl, shines under the light, adding endless brilliance and charm to the printed matter. Reverse surface oil technology can create a variety of special visual effects according to the specific requirements of the image. Among them, the wire drawing effect brings a unique visual impact to the printed matter with its unique line beauty; and the light folding grid effect makes the printed matter exhibit dynamic and changing beauty under the light, as if it is in a dreamlike world of interweaving light and shadow. These special visual effects not only enhance the artistic value of the printed matter, but also meet the needs of customers for personalized and differentiated printed matters.

[0004] However, the reverse face oil described above still has some problems. Since the coating structure is relatively simple, the wear resistance of the UV cured layer may have certain limitations. In actual application or transportation, the reverse face oil coating is easily subjected to various forms of friction such as human touch, friction with packaging materials, and slight collision during transportation. These friction factors can not only cause scratches and wear on the surface of the UV cured layer, but can also cause the coating to fall off, thereby seriously affecting the overall appearance and durability of the printed matter. Utility model content

[0005] Therefore, the utility model aims at providing a reverse face oil coating structure to solve the technical problems mentioned in the background art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a reverse face oil coating structure, comprising an adhesion layer, an outer wall of the adhesion layer is provided with an adhesive layer, an outer wall of the adhesive layer is provided with a fixed reinforcing layer, an outer wall of the fixed reinforcing layer is provided with a UV cured layer, the UV cured layer is provided with a support net inside, and an outer wall of the UV cured layer is provided with a wear-resistant layer.

[0007] By adopting the above technical scheme, the strength and durability of the overall coating structure are improved. The support net improves the strength and stability of the UV cured layer. The wear-resistant layer protects the UV cured layer and makes the coating itself more wear-resistant, thereby prolonging the service life of the overall coating.

[0008] Further, the adhesion layer is made of polyurethane resin material, and a coupling agent is added to the adhesion layer.

[0009] The polyurethane resin has a strong adhesion force due to the functional groups in its molecular structure that can react with the surface of the printing material. The coupling agent can form a chemical bond with the surface of the printing material, thereby significantly improving the adhesion strength between the coating and the printing material, and improving the adhesion force and durability of the coating.

[0010] Further, the adhesive layer is made of epoxy resin material, and a thickening agent is added to the adhesive layer.

[0011] The epoxy resin has strong adhesion and permeability, and the thickening agent can improve the viscosity of the adhesive layer, thereby improving the adhesion force and stability of the adhesive layer.

[0012] Further, the fixed reinforcing layer is made of carbon fiber material, and a crosslinking agent is added to the connection between the fixed reinforcing layer, the adhesive layer, and the UV cured layer.

[0013] By adopting the technical scheme, the carbon fiber has high strength and modulus, the crosslinking agent can promote crosslinking reaction of the resin or other high molecular compound in the adhesive layer and the UV curing layer to form a three-dimensional network structure, so that the fixed reinforcing layer has very high strength and durability, and also has good corrosion resistance and weather resistance, and is suitable for various harsh environments.

[0014] Further, the support net is a glass fiber material.

[0015] By adopting the technical scheme, strong support can be provided for the UV curing layer to prevent deformation or falling off of the UV curing layer during curing.

[0016] Further, the wear-resistant layer is a nano-silicon dioxide material.

[0017] By adopting the technical scheme, the nano-silicon dioxide can form a dense protective film on the surface of the UV curing layer due to its small particle size, large specific surface area and high surface energy, so that the wear resistance, scratch resistance and weather resistance of the UV curing layer can be significantly improved, and the nano-silicon dioxide can also improve the wettability and dispersibility of the coating and improve the overall performance of the coating.

[0018] In summary, the utility model mainly has the following beneficial effects:
