Abstract
The invention discloses a kind of graphene heat dissipation film, which is made of graphite, graphene and metal ion.The present invention utilizes graphite dilute and the combination of metal ion, forms the graphene Distribution Pattern of cross type, to reach heat dissipation and conductive force comprehensively, thus has good heat dissipation effect.
Description
Technical field
The invention belongs to the technical fields of film, in particular to the heat dissipation film of graphene production.
Background technique
Film is widely used in our daily life as a kind of covering, with the development of technology, ultrafiltration, micro-
The membrane technologies such as filter, reverse osmosis are led in electricity power, nonferrous metallurgy, sea water desalination, Water purification, reusing sewage and medicine food etc.
The engineer application scale in domain expands rapidly, and membrane technology has obtained great application.
However, heat sinking function is limited to since film usually has airtightness, common membrane structure is substantially without appointing
What heat dissipation effect is only distributed by faint surface to distribute thermal energy.
Summary of the invention
To solve the above problems, the primary purpose of the present invention is that providing a kind of graphene heat dissipation film, the heat dissipation film
Not only there is good coverage effect, also there is extraordinary heat dissipation effect.
The primary purpose of the present invention is that providing a kind of graphene heat dissipation film, which stablizes, can be extensive
Applied to various places.
To achieve the above object, technical scheme is as follows.
A kind of graphene heat dissipation film, it is characterised in that the heat dissipation film is made of graphite, graphene and metal ion.
The graphite, graphene and metal ion are constituted according to the weight ratio of 1000:50-100:1-5.
The heat dissipation film further comprises having adhesive glue, aluminium film, and the adhesive glue is coated in aluminium film, the graphite,
The mixture of graphene and metal ion is covered on above adhesive glue, is fixed in aluminium film by adhesive glue.
Graphite is mixed to prepare thermal dispersant coatings along with the dilute lattice material of graphite for having metal ion, is then added and is stained with conjunction
Glue is coated on aluminium film on piece and just completes heat dissipation film.
The metal ion is the chelating ion of iron and copper.
The graphene is 60 layers of grapheme material.
Further, the chelating ion of the iron and copper, account for graphene weight 5% are best, that is to say, that the chela of iron and copper
The weight ratio for closing ion and graphene is that 5:100 is best.
It is dilute to manufacture magnetic graphite, paramagnetism and diamagnetic metal ion are mainly had in lattice.In preparation side
The chelating ion state species that iron and copper are applied on face, are penetrated into graphene lattice.With the dilute material of 60 layers of graphite, match
After making, when being mixed with graphite and adhesive glue, coating fluid is flowed out plus magnetic force pipeline during being coated in aluminium film, can be obtained
Cross type heat dissipation film out.
Because chelates ferric ions be it is diamagnetic, copper chelating ion is paramagnetic.Under the attraction of north and south magnet, band
There is the graphite of iron copper ion lattice dilute, the heat spreading function in direction in length and breadth can be formed.Then film can achieve moves towards scattered in length and breadth
Heat effect.
Therefore, the present invention utilizes graphite dilute and the combination of metal ion, the graphene Distribution Pattern of cross type is formed, to reach
To comprehensive heat dissipation and conductive force, thus there is good heat dissipation effect.
Moreover, the heat-dissipating film structure is stablized, it can be widely applied to various places.
Detailed description of the invention
Fig. 1 by institute's implementation heat dissipation film of the invention structural schematic diagram.
Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Think in many scientific appraisals；Graphite is blocks of sheet-like state, so the electron stream and heat transfer type of graphite
All it is lateral way to get there ... and the outside conduction of longitudinal way to get there is more much smaller than transverse direction.Traditional graphite not only cannot function as dissipating
Hot material is often used as thermal insulation material.
Through inventor the study found that the heat dissipation direction of graphite is lateral feature, longitudinal aspect will lean on graphite is dilute to have
The supplement of metal ion lattice can comprehensively make cross type and radiate comprehensively and conductive force.
Therefore, the example that the present invention is implemented film as shown, the graphene radiates, includes three layers, one layer 1
It is thermal dispersant coatings, which is made of graphite, graphene and metal ion；Two layer 2 is adhesive glue, and three layer 3 is aluminium film.
Adhesive glue 2 is coated in aluminium film 3, and the mixture of graphite, graphene and metal ion is formed by thermal dispersant coatings 1 and covers
It covers above adhesive glue 2, is fixed in aluminium film 3 by adhesive glue 2.
In general, graphite, graphene and metal ion, are constituted according to the weight ratio of 1000:50-100:1-5.
Graphene is 60 layers of grapheme material.Metal ion is the chelating ion of iron and copper.Graphite, preferably nanometer
The graphite powder of grade.
Graphite as a result, along with have metal ion the dilute lattice material of graphite, be mixed to prepare thermal dispersant coatings, then plus
Enter to be stained with close glue be coated on aluminium film on piece just completes radiate film.
The chelating ion of iron and copper, account for graphene weight 5% are best, that is to say, that the chelating ion and stone of iron and copper
The weight ratio of black alkene is that 5:100 is best.
In production, in the graphite of per kilogram, the dilute lattice material gained of the graphite with metal ion of 50g is added,
Wherein metal ion is the metal ion of Chelating state, and the weight ratio of dosage and graphene is 5:100, and thermal dispersant coatings 1 are made, dissipate
Hot coating 1, which adds adhesive glue 2 and is coated in aluminium film 3, just to be completed, and heat dissipation film is made.
It is dilute to manufacture magnetic graphite, paramagnetism and diamagnetic metal ion are mainly had in lattice.In preparation side
The chelating ion state species that iron and copper are applied on face, are penetrated into graphene lattice.With the dilute material of 60 layers of graphite, answer
Five proportion of the copper and iron chelating ion about at hundred parts is proper.After preparing, when being mixed with graphite and being stained with conjunction glue, coating
Coating fluid is flowed out plus magnetic force pipeline during aluminium is thin upper, can obtain cross type heat dissipation film.
Therefore, using the heat transfer rate height of graphite and characteristic resistant to high temperature, the present invention produces the conduction of province's heat-dissipating space
Film, to help the limited electronic building brick heat dissipation in space.Again since the volume of heat dissipation film is tiny and light and handy, especially suitable for
It is inscribed between heat dissipation in LED illumination lamp and equipment.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
