Description

Technical Field

[0001] The utility model relates to the technical field of decorative films, in particular to a semi-rigid decorative film. Background Art

[0002] Decorative film is a new type of decorative material made from high molecular weight polymer (PVC) with various additives added, then processed through calendering and compounding. It can be combined with other substrates such as wood, plastic, aluminum, and iron to create a versatile decorative material. It is widely used in home appliances, audio surface decoration, interior decoration, and interior decoration of aircraft, ships, and trains. It can also be used for billboards, etc.

[0003] Since these decorative film products are exposed to the outdoors for a long time, the external sunlight shines on the decorative film for a long time, which will cause the printing on the decorative film to fade. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a semi-rigid decorative film.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a semi-rigid decorative film includes a base layer, a weakly soluble water-based glue layer is provided below the base layer, and the top surface of the base layer is provided with a hydrophobic layer, a heat-insulating layer, an antistatic layer, and a printing layer in sequence from top to bottom, and the layers are bonded together by a heat-sensitive adhesive.

[0006] As a further description of the above technical solution: the base layer is made of resin material, and the resin is a polyolefin resin component.

[0007] As a further description of the above technical solution: the hydrophobic layer is made of PTFE filter membrane material.

[0008] As a further description of the above technical solution: the thermal insulation layer is made of PO film material, and the thickness of the thermal insulation layer is 0.08 mm.

[0009] As a further description of the above technical solution: the antistatic layer is made of PVC film material.

[0010] As a further description of the above technical solution: the printing layer is a polypropylene film material, and an aluminum-plated film is wrapped on the outside of the polypropylene film material.

[0011] The utility model has the following beneficial effects:

[0012] Compared with the existing technology, the semi-rigid decorative film, by providing a heat-insulating layer on the base layer, plays a role in isolating the heat of external sunlight, thereby preventing the decorative film from fading due to long-term exposure to the sun. The hydrophobic layer provided improves the hydrophobicity of the decorative film, preventing rainwater from remaining on the outside of the decorative film and affecting the clarity of the decorative film pattern. The antistatic layer provided improves the insulation of the decorative film, preventing external dust from being electrostatically adsorbed on the outside of the decorative film, thereby ensuring the cleanliness of the decorative film. The base layer is set to α-olefin homopolymer or α-olefin copolymer, making the discarded decorative film degradable and non-toxic, and giving the decorative film better ductility, reducing the probability of the decorative film breaking at the turning point. The printing layer is set to polypropylene film material. Taking advantage of the good ductility of polypropylene film, various patterns can be easily pressed, the pattern is set on the polypropylene film, and then the required color layer is applied. The light reflection of the aluminum layer of the aluminized film can enhance the colorful visual effect. BRIEF DESCRIPTION OF THE DRAWINGS
