Abstract

The utility model discloses a composite base material structure comprising a metal base material, a diamond-like carbon film layer and a plastic layer, wherein the metal base material is provided with a surface, and the surface is concavely provided with a plurality of concave holes; the diamond-like carbon layer is combined with the surface of the metal base material and goes deep into the concave holes; and the plastic layer is combined with the diamond-like carbon layer and fills the concave holes to be full. By way of the structure, the combination strength among the composite base material layers can be effectively improved, so that the aim of prolonging the service life of the composite base material can be achieved.

Description

The composite base material structure

Technical field

The utility model relates to a kind of composite base material structure, refers in particular to a kind of composite base material structure of strengthening the bond strength of each interlayer of base material.

Background technology

Electronic product shell makes shell use composite wood usually for attractive in appearance and intensity, and existing composite wood structure is as shown in Figure 2, includes metal layer A, diamond-like carbon films B and plastic layer C; And on metal layer A, be concaved with small holes A1, and combining diamond-like carbon films B again, small holes A1 is in order to make the adhesion of diamond-like carbon films B and metal layer A stronger; And reduce the chance that comes off, still, after diamond-like carbon films B is incorporated into metal layer A; Its surface smoothing if combine with plastic layer C, can cause its both adhesion not enough again; Let plastic layer C come off easily, in addition, the too little diamond-like carbon films B that also lets easily of small holes A1 can't fill up small holes A1; And reduce the adhesion of diamond-like carbon films B and metal layer A, so be necessary to improve again the structure of composite wood to provide adhesion better composite wood.

In view of this, the design people does not attain perfect many disappearances and the inconvenience that causes in the said structure design, and deeply design, and the active research improvement has a fling at and development and Design goes out this case.

The utility model content

The purpose of the utility model is to provide a kind of composite base material structure, can promote the bond strength of each interlayer, and the useful life of effective elongate composite base material.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of composite base material structure includes:

One metal substrate includes a surface, and aforementioned surfaces is concaved with a plurality of shrinkage pools;

One diamond-like carbon films is incorporated into the surface of above-mentioned metal substrate, and gos deep into to above-mentioned shrinkage pool.

Said composite base material structure further includes a plastic layer, and aforementioned plastic layer is incorporated into said diamond-like carbon films, and fills up said shrinkage pool.

Said shrinkage pool is low wide and up narrow shape.

After adopting said structure; The utility model composite base material structure, metal substrate includes a surface, and aforementioned surfaces is concaved with a plurality of shrinkage pools; Aforementioned shrinkage pool is low wide and up narrow shape, can carry out edm on the surface of aforementioned metal ground to produce bigger aforementioned shrinkage pool; Diamond-like carbon films is incorporated into the surface of above-mentioned metal substrate, and gos deep into to above-mentioned shrinkage pool, and do not fill up said shrinkage pool, effectively promotes the bond strength of metal level and diamond-like carbon films; Plastic layer is incorporated into said diamond-like carbon films, and fills up said shrinkage pool, makes said plastic layer be able to firm being incorporated on the said diamond-like carbon films, effectively promotes the bond strength of diamond-like carbon films and plastic layer, effectively the useful life of elongate composite base material.

The specific embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

At first, see also shown in Figure 1ly, the preferred embodiment of the utility model is a kind of composite base material structure, and said composite base material can be applicable to electronic product shell, and like mobile phone, notebook computer or flat computer etc., its structure includes:

One metal substrate 1 includes a surface 11, and aforementioned surfaces 11 is concaved with a plurality of shrinkage pools 12, and aforementioned shrinkage pool 12 is low wide and up narrow shape, can carry out edm in the surface 11 of aforementioned metal ground 1 to produce bigger aforementioned shrinkage pool 12.

One diamond-like carbon films 2 is incorporated into the surface 11 of above-mentioned metal substrate 1, and gos deep into to above-mentioned shrinkage pool 12, and do not fill up said shrinkage pool 12.

One plastic layer 3 is incorporated into said diamond-like carbon films 2, and fills up said shrinkage pool 12, makes said plastic layer 3 be able to firm being incorporated on the said diamond-like carbon films 2.

The product form and the style of the foregoing description and accompanying drawing and non-limiting the utility model, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
