Abstract
The invention discloses an injection molding method of a carbon plate composite material. The injection molding method of the carbon plate composite material comprises the steps of (1), stacking pre-impregnated carbon plates according to the requirement; (2), evenly coating the surface of the stacked pre-impregnated carbon plates with a layer of thermoplastic material; (3), hot pressing and curing to form a thermoplastic material layer on the surface of the pre-impregnated carbon plates; (4), cutting the pre-impregnated carbon plates to be in required shapes, and putting the cut carbon plates in moulds; (5), performing injection moulding on the cut pre-impregnated carbon plates; and (6), taking out products formed by injection moulding. The invention also discloses an injection molding product of the carbon plate composite material, which is generated after being processed by the method. The product formed by the method is lighter and thinner than current products; meanwhile, the formed product is high in shell strength, so that the market requirement is met and the competitiveness is improved.
Description
[technical field]
The present invention relates to a kind of carbon plate composite injection molding forming method and products thereof, be specifically related to carbon plate composite injection molding forming method in notebook computer and products thereof.
[background technology]
Along with notebook computer is to frivolous future development, current each manufacturer competitively drops into the exploitation of Ultrathin notebook computer, traditional plastics have been not enough to meet and in the situation that product is frivolous, have maintained original intensity, are therefore badly in need of will developing a kind of material to meet the lightening demand of notebook computer in market.
Fibre reinforced materials is the focus that people pay close attention to always, since glass fibre and the compound fiberglass of organic resin come out, the composite that carbon fiber, ceramic fibre and boron fibre strengthen is succeeded in developing in succession, performance is constantly improved, and makes its field of compound material present one vitality.
A kind of special fibre that wherein said carbon fiber is mainly made up of carbon, its phosphorus content is different and different with kind, generally more than 90%; Carbon fiber has the characteristic of general carbon materials, as high temperature resistant, rub resistance, conduction, heat conduction and corrosion resistance etc.; But different from general carbon materials, its profile has significant anisotropy, softness, can be processed into various fabrics, shows very high intensity along fiber axis direction, and wherein carbon fiber proportion is little, therefore has very high intensity.
[summary of the invention]
In view of this, the present invention will solve in the problem that meets the intensity that also will reach certain on the lightening basis of notebook computer.
In order to achieve the above object, the invention provides a kind of carbon plate composite injection molding forming method, it comprises the following steps:
(1) preimpregnation carbon plate is carried out to storehouse on demand;
(2) preimpregnation carbon plate top layer good above-mentioned storehouse is coated with to last layer thermoplastic uniformly;
(3) hot-press solidifying moulding, makes preimpregnation carbon plate top layer form thermoplastic material layer;
(4) above-mentioned preimpregnation carbon plate cut into the shape needing and insert in mould;
(5) by the preimpregnation carbon plate injection mo(u)lding after cutting;
(6) product of injection mo(u)lding is taken out.
Preferably, described thermoplastic is the mixture of ABS resin or PMMA resin or PC resin or PC resin and ABS resin.
Preferably, the mixture of described ABS resin or PMMA resin or PC resin or PC resin and ABS resin is liquid.
Preferably, the mixture of described ABS resin or PMMA resin or PC resin or PC resin and ABS resin is powdery.
Preferably, described thermoplastic is liquid hot melt adhesive or hot melt adhesive film or thermosol rubber powder.
In addition, the present invention also provides a kind of carbon plate composite injection molding product, and this product is the product producing after said method is processed.
Compared to prior art, carbon plate composite injection molding forming method of the present invention and products thereof, in preimpregnation carbon plate top layer and the moulding of thermoplastic hot-press solidifying, make the preimpregnation carbon plate surface after solidifying form thermoplasticity interface layer, pass through again injection moulding processing procedure, make plastics can with preimpregnation carbon plate on the good then moulding of thermoplasticity interface layer.Product after the method moulding is more frivolous compared with existing product, and after moulding simultaneously, the intensity of product casing is higher, has met the demand in market and has improved competitiveness.
[accompanying drawing explanation]
Fig. 1 illustrates the flow chart into carbon plate composite injection molding forming method of the present invention.
[specific embodiment]
For object of the present invention, function and technological means are had to further understanding, now in conjunction with Fig. 1, the present invention is described in detail.
Refer to shown in Fig. 1, carbon plate composite injection molding forming method provided by the invention, comprises the following steps:
Step 101: by preimpregnation carbon plate storehouse in addition on demand;
Step 102: the preimpregnation carbon plate top layer good at storehouse is coated with last layer thermoplastic uniformly, thus the requirement of satisfied injection mo(u)lding below makes injection mo(u)lding below no longer need a glue to complete;
Step 103: the thermoplastic on above-mentioned preimpregnation carbon plate and its top layer is carried out to hot-press solidifying moulding, make the surface of the preimpregnation carbon plate after solidifying form thermoplasticity interface layer;
Step 104: above-mentioned preimpregnation carbon plate is cut into the shape of required product, then the preimpregnation carbon plate after cutting is put into injection mold, make plastics can with preimpregnation carbon plate on the good then moulding of thermoplasticity interface layer;
Step 105: the product after above-mentioned moulding is taken out.
Wherein, described thermoplastic is mixture or liquid hot melt adhesive or hot melt adhesive film or the thermosol rubber powder of ABS resin or PMMA resin or PC resin or PC resin and ABS resin.
Wherein, the mixture of described ABS resin or PMMA resin or PC resin or PC resin and ABS resin is liquid.
Wherein, the mixture of described ABS resin or PMMA resin or PC resin or PC resin and ABS resin is powdery.
In addition, the present invention also provides a kind of carbon plate composite injection molding product, and this product is the product producing after said method is processed.
Compared to prior art, carbon plate composite injection molding forming method of the present invention and products thereof, in preimpregnation carbon plate top layer and the moulding of thermoplastic hot-press solidifying, make the preimpregnation carbon plate surface after solidifying form thermoplasticity interface layer, pass through again injection moulding processing procedure, make plastics can with preimpregnation carbon plate on the good then moulding of thermoplasticity interface layer.Product after the method moulding is more frivolous compared with existing product, and after moulding simultaneously, the intensity of product casing is higher, has met the demand in market and has improved competitiveness.
