Description

a film structure

technical field

The utility model relates to a thin film structure, in particular to a thin film structure applied to the in-mold printing process.

Background technique

In recent years, with the development of science and technology and the improvement of income, consumers are not only considering the practicality and functionality of electronic products, but also the appearance, texture and aesthetic design of electronic products when purchasing electronic products.

The shells of electronic products commonly seen on the market, such as notebook computers (Notebook), mobile phones (Mobile phone), game consoles, etc., are mostly made of plastic, magnesium aluminum alloy, aluminum plate, carbon fiber or titanium alloy and other materials. , and use spraying or In-Mold Roller (IMR for short) to make quite exquisite patterns or textures on the shell, so as to increase the beauty and texture of the product. Among them, the way of printing inside the film is to print a preset pattern on a film, and then use the film feeder to bond the film and the mold cavity of the mold before injection molding. After injection molding, there is a patterned ink layer. Separated from the film, the ink layer remains on the plastic part to obtain a plastic part with a decorative pattern on the surface. There is no transparent protective film on the surface of the final product (such as the shell), and the film is only a carrier in the production process. Therefore, the advantages of in-membrane printing lie in the high degree of automation in production and the low cost of mass production, and are gradually being widely used.

However, if the casing formed by plastic injection is to form various two-dimensional (two-dimensional) textures on the surface of the casing, it is usually done by spraying ink or printing. However, these methods can only have changes in color or texture, and cannot form various texture changes with ups and downs on the shell. In other words, the plastic shell cannot show the touch feeling of metal texture.

Description of drawings

Fig. 1 is the structural representation of the utility model.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figure 1, a thin film structure is especially used in the In-Mold Roller (IMR) process, and the thin film structure includes a base layer 10, a scratchable layer 20, a release layer 30, a hard Plating layer 40 , decoration layer 50 and adhesive layer 60 .

The base layer 10 is used as a carrier for the scratch-proof layer 20 , the release layer 30 , the hard coating layer 40 , the decoration layer 50 and the adhesive layer 60 to be sequentially stacked on the surface of the base layer 10 .

Suitable scratching layer 20 is arranged on base layer one surface, and its thickness can be 3～7um, and suitable scratching layer 20 comprises the macromolecule coating of the particle of micron order, and wherein particle content is 5%～30%, makes suitable for scraping The surface of the layer 20 can be formed with concave-convex brush patterns, and the depth of the brush patterns can be between 1-10um; and the preferred depth of the brush patterns can be between 2-6um. In addition, this creation tries to cite an embodiment, the brush patterns can be formed on the other surface of the scratch-friendly layer 20 away from the base layer 10 , so that the brush patterns can be located between the scratch-friendly layer 20 and the release layer 30 .

The release layer 30 is disposed on the surface of the scratch-resistant layer 20 having brush patterns.

The hard plating layer 40 is disposed on the other surface of the release layer 30 and away from the scratch-friendly layer 20 .
