Description

Technical Field

[0001] The utility model relates to the technical field of advertising inkjet films, and more specifically to an anti-aging advertising inkjet film. Background Art

[0002] Advertising inkjet film is a material specially used for outdoor or indoor advertising. It uses inkjet technology to print patterns, texts, images, etc. on its surface to achieve the purpose of advertising.

[0003] When used for outdoor advertising display, such as large posters, banners, building enclosures, etc., the outdoor environment has great challenges on the materials, mainly including: ultraviolet radiation, temperature changes, rain erosion, wind and sand wear and chemical corrosion, etc.;

[0004] Existing advertising inkjet films {such as Publication (Announcement) No.: CN216610316U, a weather-resistant high-brightness advertising inkjet film} and {Publication (Announcement) No.: CN207156606U, a magnet advertising film}, propose to have "weather-resistant, waterproof, wear-resistant and other protective layers" to improve the anti-aging service life; but the above-mentioned defects to be solved are still relatively limited, so the advertising inkjet film still has the disadvantage that the anti-aging effect is not comprehensive enough. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-aging advertising inkjet film in order to solve the above technical problems.

[0006] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0007] The utility model provides an anti-aging advertising spray painting film, comprising a base layer, and also comprising a UV barrier layer, an anti-oxidation layer, a waterproof and moisture-proof layer and a wear-resistant layer which are sequentially bonded and fixed outside the base layer, wherein the UV barrier layer, the anti-oxidation layer, the waterproof and moisture-proof layer and the wear-resistant layer are all transparent.

[0008] As a preferred technical solution of the utility model, the UV barrier layer, the anti-oxidation layer, the waterproof and moisture-proof layer and the wear-resistant layer are sequentially adhered and fixed on the outer spray-painted side of the base layer.

[0009] As a preferred technical solution of the utility model, the UV blocking layer is a UV absorber coating or a UV stabilizer coating.

[0010] As a preferred technical solution of the present invention, the anti-oxidation layer is an antioxidant coating.

[0011] As a preferred technical solution of the utility model, the waterproof and moisture-proof layer is a polyurethane coating or a polysiloxane coating.

[0012] As a preferred technical solution of the utility model, the wear-resistant layer is a polyurethane coating or a polycarbonate coating.

[0013] As a preferred technical solution of the utility model, it also includes an anti-sticking layer fixedly arranged outside the wear-resistant layer, and the anti-sticking layer is transparent.

[0014] As a preferred technical solution of the utility model, the anti-sticking layer is a silicone resin coating.

[0015] The beneficial effects of the utility model are as follows:

[0016] A UV blocking layer 2 is provided outside the base layer 1 to provide the ability to absorb ultraviolet rays and enhance the anti-ultraviolet ability; an antioxidant layer 3 is provided outside the UV blocking layer 2 to resist oxidation reaction and prevent the base layer 1 material from deteriorating due to oxidation; a waterproof and moisture-proof layer 4 is provided outside the antioxidant layer 3 to form a dense protective layer to prevent moisture penetration and reduce the structural damage of the base layer 1 material caused by hydrolysis; a wear-resistant layer 5 is provided outside the waterproof and moisture-proof layer 4 to provide good wear resistance and scratch resistance on the surface; an anti-sticking layer 6 is provided outside the wear-resistant layer 5 to provide low surface energy, prevent adhesion during handling or storage, and reduce dirt accumulation. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural schematic diagram of the utility model.

[0018] Reference numerals: base layer-1, UV barrier layer-2, anti-oxidation layer-3, waterproof and moisture-proof layer-4, wear-resistant layer-5, anti-sticking layer-6. DETAILED DESCRIPTION Embodiment 1:

[0019] like Figure 1 As shown, this embodiment proposes: an anti-aging advertising inkjet film, comprising a base layer 1 (the base layer 1 is a film layer after advertising inkjet printing, and the material of the base layer 1 can be PVC, etc.), and also comprising a UV barrier layer 2, an anti-oxidation layer 3, a waterproof and moisture-proof layer 4 and a wear-resistant layer 5 sequentially bonded and fixed to the outside of the base layer 1;

[0020] The UV blocking layer 2, the anti-oxidation layer 3, the waterproof and moisture-proof layer 4 and the wear-resistant layer 5 are all transparent to ensure visibility;

[0021] Furthermore, the UV barrier layer 2, the anti-oxidation layer 3, the waterproof and moisture-proof layer 4 and the wear-resistant layer 5 are sequentially attached and fixed on the outer spray-painted side of the base layer 1 (as shown in the figure, when the advertisement on the base layer 1 is spray-painted only on the front surface, that is, only the UV barrier layer 2, the anti-oxidation layer 3, the waterproof and moisture-proof layer 4 and the wear-resistant layer 5 need to be sequentially arranged on the front end of the base layer 1), providing effective and accurate protection and reducing the use of materials;

[0022] Wherein: the UV blocking layer 2 is a UV absorber coating or a UV stabilizer coating, etc. (the UV absorber and UV stabilizer may be benzotriazole or benzophenone, etc.);

[0023] Benzotriazole: Highly efficient in absorbing ultraviolet rays, preventing them from penetrating the material, protecting the base layer 1 pigment from being damaged, thus slowing down the fading of the color;

[0024] Benzophenone: It has the function of absorbing ultraviolet rays, which can effectively block ultraviolet rays in a specific band and further enhance the anti-ultraviolet ability;

[0025] Wherein: the anti-oxidation layer 3 is an antioxidant coating or the like (it may be an antioxidant coating of a phenolic compound: resisting oxidation reaction and slowing down the degradation of the base material 1 due to oxidation);

[0026] Wherein: the waterproof and moisture-proof layer 4 is a polyurethane coating or a polysiloxane coating (polyurethane resin, polysiloxane resin);

[0027] Polyurethane: forms a dense protective layer to prevent water penetration and reduce the damage to the structure of the base material caused by hydrolysis;

[0028] Polysiloxane: has excellent hydrophobicity and weather resistance, can effectively prevent water erosion, and at the same time increase the flexibility and durability of the base layer 1;

[0029] Wherein: the wear-resistant layer 5 is a polyurethane coating or a polycarbonate coating (polyurethane resin, polycarbonate resin);

[0030] Polycarbonate: high hardness, can effectively resist physical wear and tear, and protect the clarity of the image printed on the base layer 1;

[0031] Polyurethane: Provides good wear resistance and scratch resistance, making this anti-aging advertising inkjet film more suitable for outdoor use.

[0032] In summary: the UV barrier layer 2, the antioxidant layer 3, the waterproof and moisture-proof layer 4 and the wear-resistant layer 5 respectively provide specific functional effects, and all have certain resistance to chemical corrosion, further improving the anti-aging effect of the advertising inkjet film. Embodiment 2:

[0033] like Figure 1 As shown, the difference between it and embodiment 1 is that it also includes an anti-sticking layer 6 bonded and fixed outside the wear-resistant layer 5; the anti-sticking layer 6 is transparent to ensure visibility.

[0034] The anti-sticking layer 6 is a silicone coating or the like to provide low surface energy, prevent adhesion during handling or storage, and reduce dirt accumulation.
