Abstract

The utility model relates to a metal and plastic materials compounded casing structure, which comprises a plastic component, a metal membrane layer and an adhesive layer. The plastic component is a casing with an inner surface, the metal membrane is coated on the inner surface of the plastic component, and the metal membrane layer is made of powdered metal materials sprayed on the adhesive layer and is formed by high temperature hot melting and cooling. Therefore, the casing has the advantages of lightness, easy formation, low manufacturing cost and the like of plastic materials, and has the functions of heat conduction/heat radiation, electric conductivity, or prevention of electromagnetic interference and the like of metal materials.

Description

The shell structure that metal and plastic material are compound

Technical field

The utility model relates to a kind of housing of article, refer to especially a kind of on plastic casing the shell structure of composition metal material.

Background technology

The shell of general article is many to be made with plastic material, considers that mainly plastic material is comparatively light and handy, be easy to moulding and low cost of manufacture etc., but the heat conduction/thermal diffusivity, the conductivity that also therefore lack metal material and had and prevent function such as electromagnetic interference.So the complex method by material, technology such as metal and plastic material be compound also constantly are studied.

As patent of invention I271137 number " the bonding method of metalwork and working of plastics and the casing that is binded thereof " of tw Taiwan bulletin, its main technical schemes is by spraying (spray) mode adhesive agent to be sprayed between metal covering and the plastic cover.Though it can reach metal and the compound purpose of plastic material, main still in order to control the thickness of adhesive agent, and in conjunction with the time, plastics still need be attached on the metalwork one by one, expend time in and problem such as manpower so have.

The utility model content

In view of this, the purpose of this utility model is to provide a kind of metal and the compound shell structure of plastic material, to reach the purpose of thinning and machining, make simultaneously housing have plastic material light and handy, be easy to be shaped and advantages such as low cost of manufacture, also have heat conduction/thermal diffusivity, the conductivity of metal material concurrently or prevent function such as electromagnetic interference.

In order to reach above-mentioned purpose, the utility model provides a kind of metal and the compound shell structure of plastic material.Described shell structure comprises:

One working of plastics as housing, and has an inner surface and an outer surface;

One metallic diaphragm is coated on the inner surface of working of plastics; And

One adhesion layer is incorporated between working of plastics and the metallic diaphragm, and described metallic diaphragm is to be sprayed on the adhesion layer with the granulated metal material, through the high temperature hot melt and cool off postforming.

As preferred version, wherein said working of plastics is the mobile computer housing.

As preferred version, wherein said working of plastics is the mobile phone housing.

As preferred version, the outer surface of wherein said working of plastics is covered with baking vanish, spraying or vacuum coating.

As preferred version, wherein said metallic diaphragm is made of zinc, aluminium or copper.

As preferred version, the thickness of wherein said metallic diaphragm is 10～20 μ m.

Compared to prior art, the utlity model has following beneficial effect:

Owing to metallic diaphragm of the present utility model is to be attached on the working of plastics with the spraying of granulated metal material to be shaped, so can reach the purpose of thinning and machining, make simultaneously housing not only have plastic material light and handy, be easy to be shaped, and advantage such as low cost of manufacture, but also have heat conduction/thermal diffusivity, the conductivity of metal material concurrently or prevent function such as EMI.

Embodiment

In order further to understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet the following drawings and embodiment only provide with reference to the usefulness of explanation, be not to be used to limit the utility model.

See also Fig. 1, Fig. 2 and Fig. 3, be respectively the stereoscopic figure at stereoscopic figure of the present utility model, another visual angle and the 3-3 section cross-sectional schematic of Fig. 2.The compound shell structure of a kind of metal provided by the utility model and plastic material comprises a working of plastics 1, a metallic diaphragm 2 and an adhesion layer 3; Wherein, described working of plastics 1 can be used as the housing of various article, for example the housing of mobile computer 4 (as shown in Figure 4) or mobile phone 5 article such as (as shown in Figure 5); And,, be not defined as flat moulding so the moulding of working of plastics described in the utility model 1 shown in the accompanying drawings is only for reference because described working of plastics 1 must cooperate pairing article on external form.Described working of plastics 1 has an outer surface 10 and an inner surface 11, and described outer surface 10 can form baking vanish, spraying, vacuum coating etc. by further handling, so that the outer surface 10 of described working of plastics 1 has more attractive in appearance as the appearance surfaces of above-mentioned article; Described inner surface 11 is then with for described metallic diaphragm 2 coatings, thereby reaches the purpose of this utility model.

The utility model is mainly by the described metallic diaphragm 2 of coating on the inner surface 11 of described working of plastics 1, thereby provide by the housing that described metallic diaphragm 2 is constituted have heat conduction/thermal diffusivity, conductivity or prevent the article of functions such as electromagnetic interference, still can have concurrently simultaneously the housing that constitutes by plastic material light and handy, be easy to advantages such as moulding and low cost of manufacture.Described adhesion layer 3 by coating one thinning on the inner surface 11 of described working of plastics 1, again with the metal material (as metals such as zinc, aluminium, copper) of want coating with powdered spray on adhesion layer 3, behind the high temperature hot melt, make the metal material multiviscosisty of powdery, thereby merge with adhesion layer 3, and at the described metallic diaphragm 2 of cooling postforming, its THICKNESS CONTROL is coated on the inner surface 11 of described working of plastics 1 to obtain a described shell structure between 10～20 μ m.

Therefore, by above-mentioned contexture, can obtain the compound shell structure of metal of the present utility model and plastic material.

In sum; the above only is preferred embodiment of the present utility model; therefore be not and limit scope of patent protection of the present utility model, so the equivalent structure variation done of the utility model specification and accompanying drawing such as all should be contained within the protection range of the present utility model.
