Description

Technical Field

[0001] This utility model relates to the field of printing and packaging materials technology, and in particular to a wear-resistant water label sticker. Background Technology

[0002] Water transfer stickers, also known as water transfer decals, are a type of material that uses water transfer printing technology to transfer patterns onto the surface of objects. They are widely used in the decoration of products made of various materials such as ceramics, glass, plastics, and metals. However, existing water transfer stickers generally suffer from insufficient wear resistance in actual use.

[0003] For example, Chinese patent CN201419604Y discloses a watermark sticker, which includes a water transfer paper, a transparent ink layer, a colored ink layer, a white base layer, a metallic ink layer, an adhesive backing layer, and a release paper.

[0004] In daily life, after a period of use, the patterns on the surface of products with watermark stickers are prone to wear and fading, affecting the product's appearance and lifespan. In industrial production, some products that need to be exposed to harsh environments for a long time have even higher requirements for the wear resistance of watermark stickers. Existing watermark stickers are difficult to meet the wear resistance requirements of these products during long-term use, resulting in reduced reliability of product marking or decoration and increased product maintenance and replacement costs. To address the above problems, a wear-resistant watermark sticker is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a wear-resistant water label sticker.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant water label sticker, comprising a release paper layer, an adhesive layer, a base layer, and a pattern printing layer, wherein an absorbent layer is provided between the base layer and the pattern printing layer, and a plurality of nano-silica particles are disposed inside the adhesive layer, the lower surface of the base layer is bonded to the release paper layer through the adhesive layer, the pattern printing layer is printed on the upper surface of the base layer, the upper surface of the pattern printing layer is coated with a wear-resistant coating, and the outer surface of the wear-resistant coating is coated with a protective layer, the pattern printing layer includes an ink layer and a protective layer, the upper surface of the protective layer is coated with an ultraviolet absorbing layer, and the upper surface of the ultraviolet absorbing layer is coated with a polycarbonate film layer.

[0007] Preferably, the base layer includes a polyester film layer, and biaxially oriented polypropylene film layers are symmetrically disposed on both sides of the polyester film layer.

[0008] Preferably, the patterned printing layer forms a three-dimensional network structure through a special cross-linking curing process.

[0009] Preferably, the thickness of the adhesive layer is 0.03 to 0.07 mm.

[0010] Preferably, the thickness of the base layer is 0.05 to 0.15 mm.

[0011] Preferably, the thickness of the protective layer is 0.02 to 0.08 mm.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by improving the base layer and the pattern printing layer, the base layer is composed of a polyester film layer and a biaxially oriented polypropylene film layer. The polyester film layer uses high-strength polyester film as the base material. The biaxially oriented polypropylene film has good stiffness and high transparency. Both the polyester film layer and the biaxially oriented polypropylene film layer have smooth and flat surfaces, reducing wear. The PET film has high tensile strength and tear strength, making it less prone to damage during the transfer process. The protective layer in the pattern printing layer contains several nano-sized wear-resistant particles, forming a micro-scale wear-resistant protective structure on the surface of the pattern after printing. When external objects rub against the pattern surface, the nanoparticles can play a buffering and anti-wear role, reducing ink wear. The polycarbonate film layer has high impact resistance, good wear resistance and transparency, and can effectively resist external friction and scratches, protecting the printed pattern.

[0014] 2. In this utility model, a wear-resistant coating and a protective layer are added to the outer surface of the pattern printing layer. The wear-resistant coating is made of silicone-modified polyurethane material, which forms a three-dimensional network structure through a special cross-linking curing process. The silicone-modified polyurethane material has excellent wear resistance, chemical resistance and flexibility. Its three-dimensional network structure can enhance the adhesion between the wear-resistant coating and the pattern printing layer, and at the same time form a hard and elastic protective coating on the surface, effectively resisting external friction and scratches. The protective layer is a transparent polyethylene terephthalate film with a thickness of 0.02 to 0.08 mm. The protective layer has good wear resistance, chemical resistance and optical properties, and can provide additional physical protection for the pattern printing layer, preventing it from directly contacting external objects and causing wear.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a wear-resistant water label sticker, including a release paper layer 1, an adhesive layer 2, a base layer 3, and a pattern printing layer 5. An absorbent layer 4 is provided between the base layer 3 and the pattern printing layer 5. The adhesive layer 2 contains a plurality of nano-silica particles 8. The lower surface of the base layer 3 is bonded to the release paper layer 1 through the adhesive layer 2. The pattern printing layer 5 is printed on the upper surface of the base layer 3. A wear-resistant coating 6 is coated on the upper surface of the pattern printing layer 5, and a protective layer 7 is coated on the outer surface of the wear-resistant coating 6. The pattern printing layer 5 includes an ink layer 51 and a protective layer 52. An ultraviolet absorbing layer 53 is coated on the upper surface of the protective layer 52, and a polycarbonate film layer 54 is coated on the upper surface of the ultraviolet absorbing layer 53.

[0023] The specific settings and functions of this embodiment are described in detail below: The watermark sticker consists of, from bottom to top, a release paper layer 1, an adhesive layer 2, a base layer 3, an absorbent layer 4, a pattern printing layer 5, a wear-resistant coating 6, and a protective layer 7. The protective layer 52 contains several nano-sized wear-resistant particles, forming a microscopic wear-resistant protective structure on the surface of the printed pattern. When external objects rub against the pattern surface, the nanoparticles can act as a buffer and resist wear, reducing ink abrasion. The polycarbonate film layer 54 has high impact resistance, good wear resistance, and transparency, effectively resisting external friction and scratches. The wear-resistant coating 6 is made of silicone-modified polyurethane material, which forms a three-dimensional network structure through a special cross-linking curing process. The silicone-modified polyurethane material has excellent wear resistance, chemical resistance and flexibility. Its three-dimensional network structure can enhance the adhesion between the wear-resistant coating 6 and the pattern printing layer 5, and at the same time form a hard and elastic protective coating on the surface, effectively resisting external friction and scratches. The protective layer 7 has good wear resistance, chemical resistance and optical properties, and can provide additional physical protection for the pattern printing layer 5, preventing it from directly contacting external objects and causing wear.

[0024] Example 2: Figure 2 and Figure 3 As shown, the base layer 3 includes a polyester film layer 31, and biaxially oriented polypropylene film layers 32 are symmetrically disposed on both sides of the polyester film layer 31. The pattern printing layer 5 forms a three-dimensional network structure through a special cross-linking curing process. The thickness of the adhesive layer 2 is 0.03-0.07 mm, the thickness of the base layer 3 is 0.05-0.15 mm, and the thickness of the protective layer 7 is 0.02-0.08 mm.

[0025] The overall effect achieved by this embodiment is that the base layer 3 is composed of a polyester film layer 31 and a biaxially oriented polypropylene film layer 32. The polyester film layer 31 uses high-strength polyester film (PET) as the base material. The biaxially oriented polypropylene film (BOPP) has good stiffness and high transparency. Both the polyester film layer 31 and the biaxially oriented polypropylene film layer 32 have smooth and flat surfaces, which can reduce the coefficient of friction with external objects, reduce wear, and facilitate the uniform coating of subsequent coatings. The PET film has high tensile strength and tear strength, which can provide basic structural support for the watermark sticker, making it less prone to damage during the transfer process.

[0026] The device's usage and working principle are as follows: From bottom to top, the water-resistant sticker consists of: release paper layer 1, adhesive layer 2, base layer 3, absorbent layer 4, pattern printing layer 5, wear-resistant coating 6, and protective layer 7. Release paper layer 1 uses a basis weight of 80-120 g / m². 2The glassine release paper has excellent release properties and flatness, ensuring that the adhesive layer 2 does not stick to the release paper layer 1 during the storage and transportation of the water label sticker. Simultaneously, the water label sticker can be easily separated from the release paper layer 1 during water transfer printing. The adhesive layer 2 uses acrylic pressure-sensitive adhesive with a thickness of 0.03–0.07 mm. Acrylic pressure-sensitive adhesive has excellent bonding properties and weather resistance, enabling the water label sticker to be firmly adhered to the surface of various materials and maintain its adhesion for a long time under different environmental conditions, preventing it from easily falling off.

[0027] The base layer 3 consists of a polyester film layer 31 and a biaxially oriented polypropylene film layer 32. The polyester film layer 31 uses high-strength polyester film (PET) as the base material. The biaxially oriented polypropylene film (BOPP) has good stiffness and high transparency. Both the polyester film layer 31 and the biaxially oriented polypropylene film layer 32 have smooth and flat surfaces, which can reduce the coefficient of friction with external objects, reduce wear, and facilitate the uniform coating of subsequent coatings. The PET film has high tensile strength and tear strength, which can provide basic structural support for the water label sticker, making it less prone to damage during the transfer process.

[0028] The absorbent layer 4 is made of a special superabsorbent polymer and cellulose. The superabsorbent polymer has good water absorption and water retention properties and can intelligently adjust the absorption and release rate of water according to the ambient humidity and moisture content. The cellulose plays a role in enhancing the structural strength of the absorbent control layer and preventing it from over-expanding and cracking during the water absorption process. The absorbent layer 4 can make water evenly penetrate into the pattern printing layer 5 when the water label sticker is transferred, avoiding problems such as blurring and deformation of the pattern due to uneven water. At the same time, it controls the water absorption rate and improves the transfer efficiency.

[0029] The pattern printing layer 5 consists of an ink layer 51, a protective layer 52, an ultraviolet absorption layer 53, and a polycarbonate film layer 54. The protective layer 52 contains several nano-sized wear-resistant particles (nano-alumina), forming a micro-scale wear-resistant protective structure on the surface of the pattern after printing. When external objects rub against the pattern surface, the nanoparticles can act as a buffer and anti-wear agent, reducing ink wear. The ultraviolet absorber in the ultraviolet absorption layer 53 can effectively absorb ultraviolet rays, preventing the pattern from fading due to ultraviolet radiation, further improving the durability of the pattern. The polycarbonate film layer 54 has high impact resistance, good wear resistance, and transparency, effectively resisting external friction and scratches, and protecting the printed pattern.

[0030] The wear-resistant coating 6 is made of silicone-modified polyurethane material, which forms a three-dimensional network structure through a special cross-linking curing process. The silicone-modified polyurethane material has excellent wear resistance, chemical resistance and flexibility. Its three-dimensional network structure can enhance the adhesion between the wear-resistant coating 6 and the pattern printing layer 5, and at the same time form a hard and elastic protective coating on the surface, effectively resisting external friction and scratches. In addition, the wear-resistant coating 6 also has good water resistance, which can prevent water from eroding the pattern printing layer 5 and improve the service life of the water label sticker in humid environments.

[0031] The protective layer 7 is made of transparent polyethylene terephthalate film with a thickness of 0.02 to 0.08 mm. The protective layer 7 has good abrasion resistance, chemical resistance and optical properties, and can provide additional physical protection for the pattern printing layer 5 to prevent it from being worn by direct contact with external objects. At the same time, the high transparency of the protective layer 7 will not affect the visual effect of the pattern in the pattern printing layer 5.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
