Abstract
The invention discloses a kind of composite, its preparation method and its preparation facilities that graphite ene coatings are coated with eptfe membrane face, composite includes：Eptfe membrane layer and graphite ene coatings, graphite ene coatings are compound in eptfe membrane layer surface and form composite；Preparation method comprises the following steps：1）Prepare the graphene coating solution of graphite ene coatings；2）Eptfe membrane is unreeled, the graphene coating solution that roller coating prepares on film surface；3）Drying, winding, curing of coatings, that is, complete the preparation of composite.By the above-mentioned means, the present invention is that have thin, light, draftability good and the new material of good toughness, there are the excellent properties such as quick conductive, heat transfer, radiating, high conductivity；With characteristics such as high conductivity, the good, ultra-thins of intensity, there is conduction, electromagnetism interference, electromagnetic shielding and the function of excellent heat conducting radiating.
Description
Technical field
The present invention relates to field of compound material, and graphene is coated with eptfe membrane face more particularly to one kind
Composite, its preparation method and its preparation facilities of coating.
Background technology
Current electronics and IT products such as delicate electronic device, consumer electronics（Mobile phone, video camera, computer and colour TV）, it is new
Energy automobile radiates for the heating of solution system, is exactly to be conducted heat heat conduction and radiating with high-quality aluminum component or copper piece through conventional structure,
Or interiors of products installation fan forced ventilation radiating；To solve the inside and outside electromagnetic interference problem of electronic component frequently with gold
Belong to shell or woven wire shielding construction, be thus current electronics and IT products volume is larger, heavier-weight, cost compared with
Greatly, the anxiety of copper bauxite resource is caused.
The content of the invention
The present invention solves the technical problem of provide one kind to be coated with graphene painting on eptfe membrane face
Composite, its preparation method and its preparation facilities of layer, there can be the characteristics such as high conductivity, the good, ultra-thin of intensity, have
Conduction, electromagnetism interference, electromagnetic shielding and the function of excellent heat conducting radiating, can develop the smaller exquisite, weight of volume it is lighter,
The lower electronics and IT products of cost.
In order to solve the above technical problems, one aspect of the present invention is：One kind is provided in e-PTFE second
The composite of graphite ene coatings is coated with alkene film surface, including：Eptfe membrane layer and graphite ene coatings, graphene apply
Layer is compound in eptfe membrane layer surface and forms composite.
In a preferred embodiment of the present invention, the thickness of composite material is 0.01-0.20mm.
The invention further relates to it is a kind of on eptfe membrane face be coated with graphite ene coatings composite system
Preparation Method, comprise the following steps：
1）Prepare the graphene coating solution of graphite ene coatings；
2）Eptfe membrane is unreeled, the graphene coating solution that roller coating prepares on film surface；
3）Drying, winding, curing of coatings, that is, complete the preparation of composite.
In a preferred embodiment of the present invention, it is 1-5m/min to unreel speed.
In a preferred embodiment of the present invention, the temperature of drying is 100 DEG C -200 DEG C.
In a preferred embodiment of the present invention, the temperature of curing of coatings is 50 DEG C -70 DEG C, and the time is at least 24h.
In a preferred embodiment of the present invention, the component of graphene coating solution includes by weight percentage：
Polyurethane resin 50-70%；
Graphene micro mist 5-40%；
Polyaniline micro mist 0-10%；
Conductive black micro mist 0-10%；
Graphene micro mist, polyaniline micro mist, conductive black micro mist are added in polyurethane resin, makees solvent with ethyl acetate, directly
To solution viscosity index (VI) reach 1000-3000CPS just stop add ethyl acetate, in a kettle dilution stirring and ultrasound
Ripple agitates 8-12h so that the micro mist disperse in solution is uniform, and then reactor vacuumizes the microbubble in discharge solution, you can
Into next procedure, eptfe membrane layer surface is coated on, forms graphite ene coatings.
In a preferred embodiment of the present invention, polyaniline micro mist or be polyethylene dioxythiophene；Conductive black micro mist or
