Description

In-mold decoration material

The present invention relates to a soft mold for In-Mold Roller (IMR) and a method of manufacturing the same, and an in-mold decorative material having the same, and an injection appearance made of the in-mold decorative material. Pieces.

Today's consumer products pay more attention to packaging, especially in order to have a sense of quality and personalization, in order to stimulate consumers' desire to buy. Therefore, the current electronic product casing design has more and more different changes to meet the user's requirements for texture. In contrast, how to make changes in the monotonous object shell, so that it has a colorful smooth surface shell, and a layered pattern is also the direction pursued by the industry.

Compared with the traditional surface decoration methods, such as spraying, thermal transfer, film coating, etc., in-mold transfer technology is currently popular surface decoration technology. Because the production process can print and decorate the surface of the plastic part at the same time as the injection filling, thereby increasing the added value of the plastic product, no secondary processing, color diversity, chemical resistance and scratch resistance of the surface of the plastic part are required. Etc., and make the appearance smooth and layered, and the continuous production is more automated.

Please refer to FIG. 1A, which is a schematic diagram of a conventional in-mold transfer material. The in-mold transfer film 1 includes a substrate 11, a release layer 12, a high-hardness protective layer 13, a pattern layer 14, and an adhesive layer 15. The in-mold transfer film 1 is attached to the inside of the mold by a film feeder to perform injection molding (not shown), and the in-mold transfer film 1 is attached to the plastic 16. Release layer after injection molding 12, the substrate 11 is separated from the in-mold transfer film 1 to obtain an ejection member 2 having a surface of a flat surface and having a high-hardness protective layer 13 and having a patterned layer 14 as shown in FIG. 1B; as shown in US Pat. 5000903 is revealed.

In order to make the surface of the injection member more stereoscopic and more colorful, it can be achieved by using the in-mold transfer film by changing the surface haze of the protective layer and the multi-color printing of the pattern layer. As shown in FIG. 2A, the in-mold transfer film 1a includes a substrate 11 on the surface of which is partially coated with a resin layer 17 containing diffusion particles, and then coated with a high-hardness protective layer 13a. A multi-color pattern printing method is used to obtain a multi-color pattern layer 14, 14a, 14b, 14c, 14d, followed by a subsequent layer 15. The in-mold transfer film 1a is fed into the mold by a film feeder to be injected into the mold for injection (not shown), and the in-mold transfer film 1a is attached to the plastic 16. After the injection molding, the substrate 11 is separated from the in-mold transfer film 1a to obtain an ejection member 2a as shown in Fig. 2B. The surface of the ejection member 2a has a partially atomized atomized surface 171 having a depression, and the patterned layer 14 14a, 14b, 14c, 14d are printed layers of a particular color; as disclosed in U.S. Patent 5,955,204.

There is also a product called hairline, which, as the name implies, has a stripe on the surface of the product, such as hairline stripes. For the manufacturing method, please refer to FIG. 3A. First, a hairy hair-like hair surface 111 is brushed on the surface of the substrate 11b by a brush wheel (the brush wheel method is not shown), and then continues as shown in FIG. 3B.

On the plastic 16. After the injection molding, the substrate 11b and the release layer 12b are separated from the in-mold transfer film 1b to obtain an injection member 2b as shown in Fig. 3C. The injection member 2b has a three-dimensional tactile hair surface 131b, and the surface structure of the hair surface 131b and the hair surface 111 on the substrate 11b are mirror images of each other. By controlling the thickness of the brush wheel and the parameters such as pressure, different appearance effects, such as long hair and short hair, can be obtained.
