Description

leather trim

technical field

The utility model relates to a leather trim, in particular to a leather trim combined with a thermoplastic layer to form an accommodating space for fitting on the outer surface of a 3C product.

Background technique

Most of the 3C product panels currently on the market are made of plastic, aluminum alloy or acrylic with a shell, and then a protective film is formed on the surface of the shell by spraying or sputtering. The panel formed by the above method can not form various textures (such as wood grain, cloth grain, etc.) in addition to expressing different colors, so as to produce a three-dimensional visual effect.

In order to solve the above problems, some operators directly combine materials such as cloth, metal, leather or wood on the surface of a housing to form a unique three-dimensional texture on the surface of the panel. However, taking leather as an example, although the above method can produce beautiful leather texture and touch on the surface of the shell, no matter whether it is animal skin or artificial leather, it has soft characteristics. Multiple steps must be taken to fix the leather, which is a waste of cost.

Furthermore, the materials of the leather and the shell are not the same. Although they can be bonded by means of pasting, the bonding strength between the two is not stable. After long-term use, the adhesive force of the glue will weaken. Separate the leather from the case.

Therefore, the applicant coats the inner surface of the leather with resin, makes the resin penetrate into the leather from the inner surface, and then molds the leather and the resin integrally to form a leather panel after the resin hardens. In this way, it is indeed possible to effectively simplify the processing steps of the panel and reduce the manufacturing cost; however, during the coating process of the resin, problems of uneven coating thickness and resin overflow are likely to occur, making the product quality not very stable.

In view of this, in order to improve the above shortcomings, reduce the processing procedure of leather veneer, ensure product quality, improve yield rate, and reduce manufacturing cost, the utility model designer has accumulated many years of experience and continuous research and development. The generation of this utility model.

Contents of the invention

The main purpose of this utility model is to provide a kind of leather veneer, when said leather veneer is combined on the outer surface of a 3C product, the user can visually observe the lines on the leather surface, so as to strengthen the stimulation and improve the quality of the product. Sales opportunity.

In order to achieve the above purpose, the technical solution adopted by the utility model is: a leather decorative panel, which is characterized in that it includes a leather layer and a thermoplastic plastic layer; wherein: the leather layer includes an outer surface and an inner surface Surface; the thermoplastic layer is combined on the inner surface of the leather layer, and the thermoplastic layer forms an accommodating space to be combined on the outer surface of a 3C product.

During implementation, the leather layer is one of animal skin or artificial skin. And the thermoplastic layer is polyurethane (PU), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), polyvinyl chloride (PVC), polyethylene (PE) or polyethylene terephthalate One of the glycol esters (PET). During implementation, the utility model further includes an adhesive layer or a bonding layer to bond the leather layer and the thermoplastic plastic layer.

Compared with the prior art, the utility model adopting the above-mentioned technical solution has the advantages of:

1. The leather and thermoplastic layer of the present invention are pre-combined and then heated and pressurized, which can effectively simplify the processing steps and reduce the production cost.

2. The utility model relies on the thermoplastic plastic layer to maintain a certain thickness, which can ensure the quality of the product, so as to be closely pasted on the outer surface of the 3C product.

Detailed ways

Please refer to FIG. 1 and FIG. 2 , which is a preferred embodiment of the leather trim 1 of the present invention, including a leather layer 2 , an adhesive layer 3 and a thermoplastic plastic layer 4 .

The leather layer 2 is a rectangular shell, which can be one of animal skin or artificial leather. The leather layer 2 includes an outer surface 21 and an inner surface 22 opposite to the outer surface 21 .

Described thermoplastic layer 4 is polyvinyl chloride (PVC) material, and described thermoplastic layer 4 also can be polyurethane (PU), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS), Polyethylene (PE) or polyethylene terephthalate (PET) or other similar materials. The thermoplastic layer 4 is pasted on the inner surface of the leather layer 2 with an adhesive layer 3 formed by coating with glue, and forms an accommodating space 5 to cover the outer surface of a notebook computer 9 (such as Figure 3).

During implementation, a bonding layer (not shown) may also be provided between the inner surface of the leather layer and the thermoplastic layer, and the bonding layer is made of thermoplastic material, which is used as the leather layer 2 and the thermoplastic layer 4. The transition interface during bonding is to make the leather layer 2 and the thermoplastic layer 4 form a tight bond. The leather layer 2 and the thermoplastic plastic layer 4 can also be in other different shapes, so as to be respectively combined on the outer surfaces of different electronic, communication or computer (3C) products.

Please refer to shown in Fig. 4, it is the molding method of the utility model leather veneer, comprises the following steps:

a. providing a leather layer;

b. bonding a thermoplastic layer to the inner surface of the leather layer; and

c. heating to soften the thermoplastic plastic layer, and simultaneously pressurizing the leather layer and the thermoplastic plastic layer to shape and form an accommodating space.

The above step c further includes a step of providing a mold (not shown) having a shape corresponding to the accommodating space 5 for forming the combined leather layer 2 and thermoplastic plastic layer 4 . When the thermoplastic plastic layer 4 is placed on a mould, the thermoplastic plastic layer 4 can be softened into a shapeable state by virtue of the heating process, and when the temperature drops, the thermoplastic plastic layer 4 can be shaped. At the same time, the leather layer 2 is fixedly formed into a rectangular shell to cover the notebook computer 9 . During implementation, the leather layer 2 can be formed into an arc shape, to be used as a shell trim plate of a mouse, or to be shaped into a shell shape of a personal digital assistant (PDA), MP3 music player or other 3C products, to be pasted on The outer surface of the 3C product.

Therefore, the utility model has the following advantages:

1. The leather and thermoplastic layer of the present invention are pre-combined and then heated and pressurized, which can effectively simplify the processing steps and reduce the production cost.

2. The utility model relies on the thermoplastic plastic layer to maintain a certain thickness, which can ensure the quality of the product, so as to be closely pasted on the outer surface of the 3C product.

The above description is only illustrative, rather than restrictive, of the present utility model. Those of ordinary skill in the art understand that many modifications, changes or equivalents can be made without departing from the spirit and scope defined in the claims.
