Consult Fig. 1 to Fig. 3, in one embodiment, the electronic product casing of a kind of carbon fiber and plastic cement integrative-structure, comprise carbon fiber sheet equipment structure 1 and the plastic cement structure 2 of injection mo(u)lding on carbon fiber sheet equipment structure 1, carbon fiber sheet equipment structure 1 offers aperture 4, a part for plastic cement structure 2 takes shape in aperture 4, thus together with being fastened with carbon fiber sheet equipment structure 1 by aperture 4.
In a preferred embodiment, aperture 4 is from the through through hole in the upper and lower surface of carbon fiber sheet equipment structure 1, shaping and the side of coated carbon fibrous sheet structures 1 of plastic cement structure 2, at least partly upper surface and at least partly lower surface, the part that plastic cement structure 2 is molded in aperture 4 is connected with the part one that plastic cement structure 2 covers the upper and lower surface of carbon fiber sheet equipment structure 1, mutually forms embedded fastening with carbon fiber sheet equipment structure 1.More preferably, carbon fiber sheet equipment structure 1 is the step structure of mid portion 110 higher than peripheral part 120, multiple through hole is opened on the peripheral part 120 of carbon fiber sheet equipment structure 1, and distribute alternately round the surrounding of the mid portion 110 of carbon fiber sheet equipment structure 1, plastic cement structure 2 wraps the peripheral part 120 of carbon fiber sheet equipment structure 1 in lateral.
In a preferred embodiment, the aperture of aperture is more than 0.4mm.
In a preferred embodiment, the upper surface of plastic cement structure 2 is concordant with the upper surface of the mid portion of carbon fiber sheet equipment structure 1.
In a preferred embodiment, electronic product casing also comprises the clear coat 3 of injection mo(u)lding at carbon fiber sheet equipment structure 1 and plastic cement structure 2 outer surface.Particularly, the thickness of carbon fiber sheet equipment structure 1 is more than 0.5mm, and the thickness of clear coat 3 is more than 0.2mm.
In a preferred embodiment, plastic cement structure 2 is carbon fiber modifying PC black plastic, and clear coat 3 is PU thermohardening lacquer.
Carbon fiber sheet equipment structure 1 with the faying face of plastic cement structure 2 can also be provided with glue.Glue is preferably OCA optical cement.
By adopting embedding buckle structure to be combined with plastic cement by carbon fiber plate, both combine more firm like this.Carbon fiber plate can be processed by CNC finishing impression, combines with it more afterwards through precision die injection moulding plastic.Also can add a little glue, make this structure more firm, play dual reinforcement effect.Clear coat 3 structurally pours into a mould formation by CCM Shooting Technique.By arranging this clear coat, the exterior design effect of people 3D no matter can be given from vision or sense of touch.Carbon fiber plate thickness can be as small as 0.5mm.Select quantity or the pore size of aperture 4 according to electronic product casing, preferably, the aperture of aperture 4 is not less than 0.4mm, and plastic cement structure 2 is molded as one by aperture 4 and carbon fiber plate, plays button fixation.The thickness being covered in the clear coat of carbon fiber and plastic surface can be as small as 0.2mm.
In one embodiment, the preparation method of a kind of carbon fiber of making and the electronic product casing of plastic cement integrative-structure, comprise plastic cement structure injection-moulding step: injection moulding is carried out to the carbon fiber sheet equipment structure 1 offering aperture 4, a part for the plastic cement structure 2 of injection mo(u)lding is taken shape in aperture 4, thus together with being fastened with carbon fiber sheet equipment structure 1 by aperture 4.
In a further embodiment, preparation method can also be included in carbon fiber sheet equipment structure 1 preparation process before plastic cement structure injection-moulding step, and the clear coat film formation step after plastic cement structure injection-moulding step, as by CCM technique injection moulded clear coating 3.
Prepared by carbon fiber sheet equipment structure 1: first interlock carbon cloth laying, and by the thick embryo sheet material of hot pressing die curing molding, the minimum thickness of this sheet material can reach 0.5mm.Then CNC engraving machine finishing impression fault structure and aperture 4 is used.The aperture of these apertures 4 is more than 0.4mm, and its plastic cement structure 2 being injection moulding below provides button fixation, can fix plastic cement well, can not come off easily.
CCM technique injection moulded clear coating: put in mould by this form workpiece, adjustment die clearance reserves certain gap, can vacate a corresponding thickness after closing molding.By injecting systems by a kind of two-component coating being poured in mould, coating process terminated after a few minutes after the coating reaction time, at this moment the product of coating can be taken out from mould.By the method for in-mold coating moulding by casting, enormously simplify the production technology of outward appearance application, thus more economical compared with traditional cost, and technique more simplifies, and the Performance and quality of material also can not be subject to any shrink.Adopt this CCM technique, the spraying coating process that tradition is complicated can be replaced, have that technique is simple, high, the economic environmental protection of production work efficiency, be beneficial to the advantages such as health.
