The present invention relates to a mobile phone case and a mobile phone protective cover having a variety of colors and patterns, and a method of manufacturing the same, and more particularly, to implement a variety of colors and patterns on the surface of the mobile phone case and mobile phone protective cover, the user has a visual effect It relates to a mobile phone case and a mobile phone protective cover having a variety of colors and patterns that can be expected and a method of manufacturing the same.

In general, a mobile phone can be divided into a slide and a folder type, and such a mobile phone has a variety of colors in one model, and a user selects and uses one of them.

As described above, the conventional mobile phones are mostly made of a single color, and there is a problem in that they are easily tired of the consumer. In particular, the company logo and name are engraved on the surface of the mobile phone, which is simply embossed. As it is difficult to maximize the design effect, and after a certain time there was a problem that the coated part is peeled off or discolored.

In order to solve the above problems, a mobile phone protective cover is fastened to the mobile phone case. Such a mobile phone protective cover merely performs a function of protecting a mobile phone with a color such as transparent or black, and it is required to develop a mobile phone protective cover having a design and color that can satisfy various consumer's needs.

Therefore, the present invention is implemented to have a variety of colors and patterns on the mobile phone case and the protective cover, the mobile phone case having a variety of colors and patterns that can produce a user's own style and expect a visual effect An object of the present invention is to provide a mobile phone protective cover and a method of manufacturing the same.

Cell phone case and mobile phone protective cover manufacturing method of the present invention for achieving the above object comprises a molding step of manufacturing a synthetic resin, plastic (PC, ABS) material; Forming a coat layer having various colors by mixing color paints and thinners in the molding in a weight ratio of 1.2 to 1.4; A first drying step of drying the undercoat layer by 80%; The mold plate engraved with the pattern is installed on the upper mold, the molding coated with the undercoat coating layer is installed on the lower mold, and a thin film is disposed between the mold plate and the molding, and then the upper portion of the undercoat coating layer is hot stamped. A pattern layer forming step having various patterns and colors on; Forming a top coat layer for coating PVC and UV coating on the bottom coat layer and the pattern layer; And a second drying step of drying the bottom coat layer and the top coat layer.

It will be described below in more detail based on the accompanying drawings of the present invention.

1 is a block diagram showing a method of manufacturing a mobile phone case and a mobile phone protective cover according to the present invention, Figure 2 is a schematic view showing a hot stamping process according to the present invention, Figure 3 is a mobile phone case and a mobile phone protective cover according to the present invention Partial cross-sectional view of, Figure 4 is a perspective view showing a mobile phone protective cover as an example according to the present invention.

As shown in Figures 1 to 4, the manufacturing method of the mobile phone case and the mobile phone protective cover (hereinafter referred to as "molding") having a variety of patterns and colors of the present invention is a molded article manufacturing step (S1) and the undercoat coating layer forming step (S2), the first drying step (S3), the glyph layer forming step (S4), the top coat layer forming step (S5) and the second drying step (S6).

The molding manufacturing step (S1) is provided with a synthetic resin, plastic (PC, ABS) material, and injection molding the molding 10 having a predetermined shape and shape.

The undercoat coating layer forming step (S2) is a mixture of color paint and thinner (thinner) 1: 1.2-1.4 by weight ratio to coat the undercoat coating layer 20 on the surface of the molding (10). In particular, the color paint is provided in the liquid phase to have a variety of colors, it is preferable to use a paint suitable for the molding 10 of the synthetic resin and plastic material.

The first drying step (S3) is dried at 120 ° C. for 20-30 minutes on the undercoat coating layer 20, and maintains the entire undercoat coating layer 20 dried at about 80-95%.

And the first drying step (S3) is that hot air drying or a drying method by a lamp can be applied.

The pattern layer forming step (S4) is first designed a copper plate formed with a desired pattern, pictures, letters, etc. (hereinafter referred to as the 'pattern'), and then injecting a rubber material into the pattern of the copper plate, the mold plate that appears as it is (50) ).

As shown in FIG. 2, the present invention uses a hot stamping operation, and mounts a mold plate 50 on an upper mold, and installs the molded product 10 that has undergone the first drying step in a lower mold. The thin film 60 is disposed between the plate 50 and the molding 10. In this state, heat and pressure are applied to the mold plate 50, the thin film 60, and the molded product 10, so that the pattern layer 30 having various patterns and colors in a negative or embossed manner is formed on the undercoat coating layer 20. do.

The thin film 60 may have various colors such as silver or gold, and cellophane, aluminum foil, silicon treated paper, and the like, which are naturally transferred when heat is applied to the mold plate 50, may be provided with various materials.

As described above, the bottom coat layer forming step (S2), the first drying step (S3) 80% in the dried state of the pattern layer forming step (S4) is made, which is transferred to the mold plate 50 When heat (60-140 ° C.) and a predetermined pressure are applied, the pattern of the mold plate 50 is in close contact with the thin film 60 while being pressed at a predetermined interval on the upper coating layer 20 at a predetermined interval. This is to be formed.

On the other hand, the undercoat coating layer 20 and the thin film 60, the pattern layer 30 is made of a laminated structure, when looking at the pattern layer 30 from the outside can be expected a hologram effect.

The top coat layer forming step (S5) forms a top coat layer 40 by applying PVC and UV paint on the top coat layer 20 and the pattern layer 30.

The top coat layer 40 may be provided as a transparent or semi-transparent body, a silver or gold coating film may be added to the PVC, UV paint to give a three-dimensional effect on the surface.

The second drying step (S6) is a top coat layer 40 formed on the molding 10, the top coat layer 40 and glyph layer 30, 20% undried bottom coat layer at about 30-40 minutes at 120 ℃ It is drying 20 at the same time.

As such, as the bottom coat layer 20 and the top coat layer 40 are dried in the second drying step S6, the adhesive strength of each other is doubled. And the finished molding 10 can be obtained a smooth surface, it is possible to minimize the occurrence of cracks and wrinkles.

As shown in Figures 3 and 4, the mobile phone case and the mobile phone protective cover manufactured by a method of manufacturing a mobile phone case and a mobile phone protective cover having a variety of patterns and colors of the present invention is injection molded molded of a synthetic plastic material (10) and; A paint coating layer 20 having a variety of colors by mixing color paint and thinner in the molding 10; A pattern layer 30 having various patterns and colors by hot stamping on the upper coating layer 20; The upper coating layer 20 and the pattern layer 30 is composed of a top coat layer 40 for coating a PVC, UV paint on top.

In the above description of the characteristics of the present invention based on the preferred drawings, various modifications can be made by those skilled in the art to which the present invention pertains without departing from the objects, configurations, and effects of the present invention. .

Therefore, the molding of the present invention forms a pattern layer using a hot stamping operation on the undercoat coating layer of the molding, and a top coat layer is formed on the undercoat coating and the pattern layer, so that the surface is smooth and cracks or wrinkles are caused by external impact. There is an effect that can minimize the occurrence of.

In addition, a pattern layer having various patterns and colors is formed on the molding, so that a hologram effect can be obtained when viewed from the outside, and various colors and patterns can be transmitted compared to conventional products to satisfy various needs of consumers. have.
