Description

Method for manufacturing surface decoration layer

The invention relates to a method for manufacturing a surface decoration layer, in particular to a method for manufacturing a layer structure that can be decorated on the surface of a variety of substrates.

Please refer to FIG. 6, generally when a substrate A with a smooth surface wants to show textures and colorful effects that change with the viewing angle, a transparent decorative layer 10 is added on the surface of the substrate A. The steps are as follows: : STEP1: Coat a UV-curing adhesive 11 on the surface of the substrate A; STEP2: Form an optical structure 11A with uneven lines on the surface of the UV-curing adhesive 11; STEP3: Irradiate an ultraviolet light to cure the optical structure 11A; A light-transmitting protective sticker 13 is formed on the optical structure 11A.

Each layer of the transparent decorative layer 10 is transparent. When an eye E sees the surface material of the substrate A through the transparent decorative layer 10, the optical structure 11A reflects and refracts the ambient light, making the eye E E receives reflected light of different intensities, so that the light-transmitting decorative layer 10 presents a complex pattern that causes a colorful effect that changes with the angle.

Although the light-transmitting decorative layer 10 uses the surface color of the substrate A and the concave-convex pattern of the optical structure 11A to show texture and color changes that can be changed with the viewing angle, the texture effect is caused by the multiple reflections and colors of the optical structure 11A. Refraction causes the eye E to receive the surface reflection of the substrate A. When the substrate A has a darker natural color or poor reflectivity, the lines produced by the reflection and refraction of the optical structure 11A will become inconspicuous. The visual texture effect is greatly reduced; when the transparent decorative layer 10 is added to the existing manufacturing process, the substrate A is used as the base and successively stacked in the above steps. If one of the materials is flawed or the steps are wrong, the light transmission will be affected. The overall presentation effect of the decoration layer 10 makes the mass production of the manufacturing process difficult.

In order to overcome the existing problem of inconspicuous lines caused by the transmission, reflection and refraction of the transparent decoration layer 10, the present invention provides a method for manufacturing a surface decoration layer, which can not only decorate the surface of a variety of materials, but also increase the demand for mass production.

To achieve the above objective, the present invention provides a method for manufacturing a surface decoration layer, the steps of which include:

STEP1: Coat a hardened layer on a first release film, and wait for the hardened layer to cure to obtain a decorative layer protection layer. The hardened layer is made of light-transmitting material.

STEP2: A pattern layer is formed on a second release film. The pattern layer is a raised pattern structure, and an energy is applied to the pattern layer to cure it.

STEP3: A reflective layer is formed on the surface of the cured texture layer to obtain a semi-finished decorative layer with reflective gloss texture.

STEP4: A transparent bonding adhesive layer is formed on the surface of the semi-finished decorative layer, and the bonding adhesive layer is attached to the hardened layer of the decorative layer protective layer to obtain a prefabricated decorative layer.

Further, the second release film of the pre-decorative layer is removed, an adhesive layer is coated on the bottom surface of the texture layer, and the adhesive layer is attached to a substrate. After the adhesive layer is fully cured, remove In addition to the first release film, a smooth decorative surface with glossy textures is obtained.

Further, the method for forming the texture layer on the surface of the adhesive layer is printing, brushing, transfer bonding or pressing.

Further, the method for forming the reflective layer on the surface of the texture layer is electroplating, vacuum evaporation, sputtering or ion plating.

Further, the reflective layer is made of metal material.

Further, the first release film is polyolefin (PO), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or polyethylene terephthalate (PET); The second release film is polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC) or polyolefin (PO).

In the present invention, the decorative protective layer and the semi-finished decorative layer are formed on the first and second release films respectively, and then the prefabricated decorative layer is obtained by gluing. The process of prefabrication and transfer can be used to simplify the steps to achieve a large number of Rapid production not only improves the yield of finished products, but also has mass production.

As shown in the preferred embodiment shown in FIGS. 1 and 2, the present invention is a method for manufacturing a surface decoration layer. The surface decoration layer structure can be formed on the surface of a substrate A, which includes an adhesive layer laminated in sequence 21. A texture layer 22, a reflective layer 23, a bonding adhesive layer 24, and a hardened layer 25.

The texture layer 22 is bonded to the surface of the adhesive layer 21, the reflective layer 23 is coated on the surface of the texture layer 22, the bonding adhesive layer 24 is bonded on the surface of the reflective layer 23, and the hardened layer is bonded on the surface of the bonding adhesive layer 24 25. The hardened layer has a smooth surface, and the bonding adhesive layer 24 and the hardened layer 25 are both light-transmitting high molecular polymers.

The texture layer 22 has a texture structure 221 embossed, the texture layer 22 is an ultraviolet curing (UV) glue, the texture structure 221 is formed by printing, coating or pressing methods, the aforementioned pressing method is to first harden the ultraviolet rays After the glue is coated on a release film, mechanical force is applied to extrude the texture structure 221 on the surface of the texture layer.
