Description

Technical Field

[0001] This utility model relates to the field of printing materials technology, specifically to a UV-resistant printing sheet. Background Technology

[0002] In the modern printing industry, sheet materials are widely used. As people's requirements for the quality and durability of printed materials continue to increase, the performance of printing sheets is also facing higher challenges.

[0003] Currently, existing printing sheets have several significant shortcomings in practical use. Firstly, when exposed to the natural environment for extended periods, especially under direct sunlight, the lack of effective ultraviolet (UV) protection makes them susceptible to UV erosion. UV rays damage the molecular structure of the sheet, causing fading and severely impacting the appearance quality of printed materials. For example, printing sheets used in outdoor advertising and signage gradually fade and lose their original vibrancy after a period of sun exposure. Secondly, UV rays also cause the printing sheets to age and become brittle. Over time, the physical properties of the sheet gradually decline, making it brittle and easily damaged, reducing its lifespan. This not only increases the cost of replacing the sheet but also brings numerous inconveniences to practical applications. Furthermore, in some special applications, such as display screen protection sheets for electronic products and lenses for optical instruments, the requirements for UV resistance are even higher. If the sheet cannot effectively block UV rays, it may adversely affect the performance of electronic products and the precision of optical instruments. In conclusion, the problem of poor UV resistance in existing printing sheets urgently needs to be addressed, and a new type of sheet with good UV resistance needs to be developed. High-performance printing sheets have significant practical implications. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a UV-resistant printed sheet, comprising a base layer, wherein a UV-resistant layer is fixedly disposed on the upper end of the base layer, the base layer is made of a high-strength, corrosion-resistant material, such as polycarbonate PC, polyethylene terephthalate PET, etc., the base layer serves to provide support and strength for the entire printed sheet, an adhesive layer is fixedly disposed on the upper end of the UV-resistant layer, and a printing layer is fixedly disposed on the upper end of the adhesive layer;

[0008] The UV-resistant layer includes a nano-titanium dioxide UV-resistant coating, a nano-zinc oxide UV-resistant coating, a UV absorber UV-resistant coating, and a hindered amine light stabilizer UV-resistant coating. The nano-titanium dioxide UV-resistant coating is fixedly disposed on the upper end of the base layer.

[0009] Preferably, a nano-zinc oxide anti-UV coating is fixedly disposed on the upper end of the nano-titanium dioxide anti-UV coating, an ultraviolet absorber anti-UV coating is fixedly disposed on the upper end of the nano-zinc oxide anti-UV coating, and a hindered amine light stabilizer anti-UV coating is fixedly disposed on the upper end of the ultraviolet absorber anti-UV coating.

[0010] Preferably, the adhesive layer can be made of environmentally friendly glue or hot melt adhesive, etc. The function of the adhesive layer is to ensure the bonding force between the printed layer and the UV-resistant layer and to prevent the printed layer from falling off during use.

[0011] Preferably, the printing layer is disposed above the adhesive layer and is used to print various patterns and text. The printing layer can use printing materials such as ink and paint, which have good adhesion and printing effect. The printing layer can be adjusted according to the requirements of the printing pattern.

[0012] Preferably, a rubber anti-slip pad is fixedly provided at the lower end of the base layer.

[0013] Preferably, the rubber anti-slip pad has good anti-slip properties, preventing the printed sheet from sliding during use.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This UV-resistant printing sheet incorporates a nano-titanium dioxide anti-UV coating. Nano-titanium dioxide possesses strong UV absorption and scattering capabilities, converting UV rays into heat or low-energy radiation, thus reducing UV damage to underlying materials. Nano-titanium dioxide also boasts high chemical stability, is non-toxic, and odorless. Furthermore, the addition of a nano-zinc oxide anti-UV coating provides excellent UV absorption and scattering properties, effectively blocking both UVA and UVB rays across a broad absorption range. Nano-zinc oxide also exhibits antibacterial and anti-mildew properties, enhancing the hygienic properties of the printing sheet.

[0016] 2. This UV-resistant printing sheet incorporates a UV absorber coating. UV absorbers are organic compounds that can absorb ultraviolet light and convert it into harmless energy. They typically have specific molecular structures and can selectively absorb radiation within the ultraviolet wavelength range. There are many types of UV absorbers, including benzotriazoles, benzophenones, and triazines. Furthermore, a hindered amine light stabilizer coating is incorporated. Hindered amine light stabilizers are organic compounds with highly efficient light-stabilizing properties. They can capture free radicals and prevent their oxidative degradation of the material, thereby improving the material's weather resistance. Hindered amine light stabilizers also have advantages such as heat resistance and chemical corrosion resistance.

[0017] 3. This UV-resistant printed sheet is equipped with rubber anti-slip pads, which have good anti-slip properties to prevent the printed sheet from sliding during use. The adhesive layer ensures the bonding strength between the printed layer and the UV-resistant layer, preventing the printed layer from falling off during use. Attached Figure Description

The adhesive layer 3 can be made of environmentally friendly adhesives or hot melt adhesives.

The printed layer 4 is disposed above the adhesive layer 3 and is used to print various patterns and text. The printing layer 4 can be made of printing materials such as ink and paint, which have good adhesion and printing effect. The printing layer 4 can be adjusted according to the requirements of the printing pattern.

The adhesive layer 3 ensures the bonding force between the printing layer 4 and the UV-resistant layer 2, preventing the printing layer 4 from falling off during use. To further improve the UV resistance of the printing sheet, some auxiliary materials, such as antioxidants, light stabilizers, and flame retardants, can be added to the UV-resistant layer 2. These auxiliary materials can effectively improve the stability and durability of the UV-resistant layer 2, and also give the printing sheet other properties, such as anti-oxidation and flame retardancy. In addition, to improve the strength and stability of the printing sheet, some reinforcing materials, such as glass fiber, carbon fiber, and metal fiber, can be added to the base layer 1. These reinforcing materials can effectively improve the strength and rigidity of the base layer 1, and also improve the heat resistance and cold resistance of the printing sheet.
