Description

Technical Field

[0001] This utility model relates to the field of decorative film technology, and in particular to an environmentally friendly brushed embossed film. Background Technology

[0002] Steel plates are now widely used in industry and daily life, especially thin plates, which are used in automobiles, refrigerators, washing machines, and high-end room partitions, among other things. Generally, a protective or decorative layer is applied to steel plates. However, since most ordinary steel plates are shipped in a rough, unfinished state, this painting work is usually done after the steel plates have been processed into finished or semi-finished products, causing many inconveniences for manufacturers. Furthermore, steel plates often have a short lifespan after painting or coating, are prone to rust and corrosion, and also affect the product's appearance.

[0003] Currently, there are also plastic films on the market that offer both protection and a good appearance when used on composite steel plates. For example, Chinese Patent Publication No. CN 203527996 U discloses an environmentally friendly PCM brushed and embossed sheet, including a base steel plate. The front of the base steel plate is coated with a topcoat layer, and the back is coated with a backcoat layer. A brushed layer is formed on the topcoat layer, and an embossed layer is formed on the surface of the brushed layer. However, decorative films on composite steel plates generally use PE plastic as the base material, but PE plastic has the defect of poor aging resistance. In the prior art, anti-aging additives are generally added to improve the aging resistance of PE plastic. Although this method can increase the aging resistance of PE plastic, it greatly increases the cost. Although there are also decorative films using fluorocarbon PDF film as the base material, their metallic texture and three-dimensional effect are poor and need further improvement. Therefore, it is necessary to provide a new environmentally friendly brushed and embossed film to solve the above-mentioned technical problems. Utility Model Content

[0017] The above solution will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrating the present invention and are not intended to limit the scope of the present invention. The implementation conditions used in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0018] The environmentally friendly embossed film of this utility model embodiment is described in [reference]. Figure 1It includes a substrate layer 10 and a first coating layer 20 and a second coating layer 50 respectively disposed on two surfaces of the substrate layer 10, wherein, for example Figure 1 The substrate layer 10 shown is coated with a first coating layer 20 on its upper surface, and a second coating layer 50 is coated with its lower surface. In this embodiment of the invention, the substrate layer 10 is a conventional fluorocarbon PDF film available on the market. On the side of the first coating layer 20 facing away from the substrate layer 10, i.e., the fluorocarbon PDF film, from the inside out... Figure 1 The diagram shows a first processing layer 30 and a second processing layer 40 arranged sequentially from bottom to top. In this embodiment of the invention, one of the first processing layer 30 and the second processing layer 40 is a brushed layer formed by a brushing process, and the other is an embossed layer formed by a embossing process. Optionally, the first processing layer 30 can be a brushed layer and the second processing layer 40 can be an embossed layer. As an alternative embodiment, the first processing layer 30 can be an embossed layer and the second processing layer 40 can be a brushed layer. As another alternative embodiment, both the first processing layer 30 and the second processing layer 40 can be either brushed layers or embossed layers, but the brushed layers may have slightly different forms, such as brushing directions opposite for a more aesthetically pleasing metallic texture; or the embossed layers may have different patterns, such as mirror symmetry, for a stronger three-dimensional effect. The specific embossed pattern or brushed structure of the substrate layer 10 is not described in detail or limited, and those skilled in the art can select and design according to actual needs. The thickness of the substrate layer 10 is not limited and can be selected as 0.2-1.0 mm.

[0019] In this embodiment of the invention, the fluorocarbon PDF membrane substrate layer 10 typically refers to a polyvinylidene fluoride (PVDF) membrane, a polymer material. PVDF membranes possess excellent weather resistance, chemical corrosion resistance, oxidation resistance, and photoaging resistance. This membrane material undergoes special treatment to exhibit good hydrophilicity, effectively improving the filtration efficiency of the membrane element and achieving a higher water production rate. PVDF membranes also exhibit good chemical corrosion resistance, oxidation resistance, and photoaging resistance; regular cleaning effectively removes impurities contained within the membrane. Furthermore, PVDF membrane materials have wide applications in membrane structure engineering, such as roof and facade coverings of buildings, stadiums, exhibition halls, and warehousing facilities. The characteristics of PVDF membrane materials make them an ideal choice for various application scenarios, especially in situations requiring weather resistance and advanced aesthetics. For example, they are commonly used in high-end building projects, airport terminals, large event venues, exhibition centers, and other membrane structure projects requiring both weather resistance and advanced aesthetics. Furthermore, PVDF film is also used to manufacture photovoltaic backsheets because of its excellent weather resistance and chemical corrosion resistance, which effectively protects solar cells from environmental factors and improves their lifespan and performance. In summary, this invention utilizes PVDF film with UV resistance and aging resistance, and since automotive exterior steel panels are frequently exposed to sunlight, this improves the UV resistance and aging resistance of both the decorative film and the steel panel, thereby extending the product's lifespan.

[0020] For the first coating layer 20 and the second coating layer 50, conventional coating or spraying methods are used to bond them to the upper and lower surfaces of the substrate layer 10, i.e., the fluorocarbon PDF film. In this embodiment of the invention, conventional nano-waterborne paint or nano-oilborne paint available on the market can be selected. Nano-waterborne paint is preferred because it has high temperature resistance, does not corrode objects, has a strong bond, and is not easy to peel off even when exposed to sunlight. Moreover, nano-waterborne paint is more environmentally friendly. The thickness of the first coating layer 20 and the second coating layer 50 is not particularly limited or described, and those skilled in the art can select and design according to the actual scenario or the required amount of nano-waterborne paint. Optionally, the second coating layer 50 is a nano-waterborne epoxy resin coating. The main characteristic of waterborne epoxy resin is its excellent anti-corrosion performance. In addition to being used in automotive coatings, it is also used in medical devices, electrical appliances, and light industrial products. Another alternative embodiment is that the second coating layer 50 is a conventional fluorocarbon coating available on the market. It has weather resistance, heat resistance, low temperature resistance, chemical resistance, and also has unique non-stick and low friction properties. The colors of the first coating layer 20 and the second coating layer 50 are not specifically limited. Those skilled in the art can select and design according to actual needs, so that the film can present a variety of colors as required, thereby improving the market competitiveness of the product.

[0021] In summary, the environmentally friendly brushed and embossed film of this embodiment uses a fluorocarbon PDF film with good aging resistance as the substrate layer 10, which greatly improves the aging resistance of the product. A first treatment layer 30 and a second treatment layer 40 are provided on the first coating layer 20. The first treatment layer 30 and the second treatment layer 40 can be selected as brushed layers and / or embossed layers. The brushed layer has a simple processing technology, low cost and metallic texture, while the embossed layer gives the film surface a three-dimensional leather texture effect, improving the appearance of the product.

[0022] Additionally, it should be noted that, Figure 1 The thicknesses shown for each layer do not represent their actual thicknesses.

[0023] The above examples are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
