Reflective film for substrate with three-dimensional color glare effect and method for molding foamed substrate

The invention relates to a method for forming a reflective film and a foamed substrate of a substrate with a three-dimensional color glare effect, in particular to a manufacturing method which is simple in production and can stably integrate the plate and the foamed substrate. method.

According to the pattern set on the early plate-like substrate [label] is directly printed, so the pattern is flat, because the flat pattern is more monotonous, can not meet the needs of consumers, so there are related operators The R&D design is based on the technique of forming a three-dimensional pattern on a substrate [label].

For example, in China's certificate No. I288701, the "in-mold forming label structure" invention patent case includes: a raw material layer, a raw material layer and a hardened layer, and an embossing layer is produced by laser embossing technology on the outer side of the hardened layer; a coating layer is formed on the outer side of the hardened layer by electroplating; and/or a coating layer which can be combined with the printing ink is disposed outside the embossed layer, or a coating layer which can be combined with the printing ink is disposed on the coating layer, and thus, The glue layer is printed with a decorative layer or a printed layer of characters; that is, an in-mold label having a decorative pattern effect can be produced. However, when the molded label is manufactured, the embossed layer is bonded to the printed layer or the coating layer and the printed layer through the adhesive layer, so that the label is applied to the in-mold injection molding. When the high-temperature environment of injection molding is easy to change the quality of the coating layer, which affects the adhesion and flatness between the embossing layer and the printing layer or the coating layer and the printing layer, the plastic product using the label becomes a product and cannot be sold. It must be discarded and sold, and the products that must be discarded will not only cause a huge burden on the operating costs of the operators, but also a considerable waste of the use of material resources, and it is very environmentally friendly.

The main object of the present invention is to provide a method for forming a reflective film and a foamed substrate which can be stably combined with the foamed substrate without causing degumming due to a subsequent high-temperature injection process.

The above main objects and effects of the present invention are achieved by the following specific technical means:

A method for forming a reflective film and a foamed substrate of a substrate having a three-dimensional color glare effect, wherein a plating layer is plated on one surface of a plate to form a reflective film, and the opposite of the coating layer on the plate The surface coating has a foaming substrate, so that the reflective film and the foamed substrate can be stably combined without using an adhesive, thereby achieving a substantial improvement in the yield of the finished product and the competitiveness of the industry. Effective person.

The molding step of the method for forming the reflective film and the foamed substrate of the substrate having the three-dimensional color glare effect of the present invention is:

A. Set the plate;

B. setting a coating layer: the surface of the sheet is plated with a coating layer to form a reflective film;

C. Providing a foamed substrate: the sheet is foamed on the other surface of the opposite coating layer so that the foamed substrate covers the sheet and is integrated with the sheet.

Accordingly, the present invention utilizes a method of laminating a foamed substrate and a reflective film into one body, which is not only simple to manufacture, but also enables the reflective film and the foamed substrate to be firmly integrated, when it is applied to When injection molding of plastic products, the yield of finished products can be greatly improved, so that the products that need to be discarded can be reduced, and the material resources are not wasted improperly, thereby achieving the substantial effect of being environmentally friendly and industrially competitive.

Further, in the sheet of the present invention and the foamed substrate, a plastic of the same material or the same characteristics is used, and the bonding between the sheet and the foamed substrate can be made more compact.

For a more complete and clear disclosure of the technical content, the purpose of the invention and the effects thereof achieved by the present invention, it is explained in detail below, and please refer to the drawings and drawings:

Accordingly, when the production is carried out, please refer to the second and third figures together, which is a flow chart of forming a reflective film and a foamed substrate of the substrate having the three-dimensional color glare effect of the present invention, and the molding step is :

A. setting plate (11): the plate (11) can use polypropylene [PP, polypropylene] or polyethylene terephthalate (PET, polypropylene);

B. The coating layer (12) is provided: a plating layer (12) is plated on the surface of the sheet (11), and the sheet (11) and the coating layer (12) form a reflective film (1);

C. Providing a foaming substrate (2): causing the sheet (11) to integrally eject the foamed substrate (2) on the other surface of the coating layer (12) to make the foamed substrate (2) coating on the other surface of the plate (11) without the coating layer (12), and firmly integrated with the plate (11);

According to this, the molding step of the light-reflecting film (1) and the foamed substrate (2) is completed. When it is desired to further fabricate the substrate having the three-dimensional color glare effect, then in step C above, a step D and a step E are continued, that is, [see the fourth and fifth figures below]:

D. Setting embossing (4): pressing the molding layer on the coating layer (12); wherein the embossing (4) is a stable combination of the reflective film (1) and the foaming substrate (2) After being integrated, the molding machine is further formed by pressing, or the grain (51) is directly placed on the surface of the wheel (5) which is pressed out by the laminating film, so that the foaming substrate (2) is pressed out in one piece. During molding, the embossing (4) is simultaneously formed on the coating layer (12) by using the concave and convex lines (51) on the surface of the wheel (5);

E. Providing a printed layer (3): a printed layer (3) having any one of a pattern or a letter or a combination thereof is printed on the coated layer (12).

The foamed substrate (2) and the sheet (11) which are formed by lamination are made of the same material or the same characteristic material, so that the foamed substrate (2) and the sheet (11) can be firmly combined.

Wherein, the wheel (5) of the present invention is optimally arranged by a group of at least two wheels (5), and the surface of the wheel (5) on one side is provided with a concave and convex line (51), and the other wheel has (5) The surface has a smooth surface.
