To lifting, internal structure becomes increasingly complex, for the operation of various softwares, the arithmetic speed sum of smart mobile phone internal processor
Amount is also being stepped up, and processor can produce more heats when working；On the other hand, user is more willing to thinner using thickness
Mobile phone, this require interior of mobile phone component structural will ultrathin, in order to support the multi-functional of mobile phone and at high speed, this needs
More electric energy are consumed, causes each parts to produce heat many, while the client of smart mobile phone prefers giant-screen and sees point
The high picture of resolution, liquid crystal display need more light emitting diodes, and this can also produce more heats, when processor works
The heat distributed when the heat for distributing and liquid crystal display operation produces synergistic effect, if heat is shed not in time, can affect hand
The operating rate of machine, battery capacity, more serious meeting cause failure to occur, so smart mobile phone heat dissipation problem urgent need to resolve and changing
It is kind.
At present, various heat sink materials have been widely used for electronic equipment, it is relatively common for graphite material or
Graphite multilayer materials, though graphite material has the heat conductivility in higher level direction, vertical heat transfer poor performance, folding resistance
Difference, the strength of materials is weak, can tear easily or the easy displacement in adhered to position and produce breakage, and easy dry linting.
Polymer is more and more applied in heat sink material at present, macromolecular material light weight, low cost.Wherein gather to benzene
Dioctyl phthalate second diester（Polyethylene terephthalate, abbreviation PET）, which has preferable chemical stability, higher
Heat resistance, when being heated, thermal deformation is less, can keep the stability of physical aspect, and which is widely applied as radiating
The mould release membrance or matrix of structure, but another kind of macromolecular material polyethylene terephthalate -1,4-CHDM
Ester { Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene
Terephthalate), abbreviation PETG }, compared with PET, which has more prominent pliability, high impact strength, excellent resistance to
Chemical corrosivity, high grade of transparency glossiness and anti-scratch colored performance, excellent in weather are applied to heat sink material, can strengthen product
The folding resistance of product, impact resistance and transparency.
Metal is due to having higher thermal conductivity factor and heat storage capacity strong, and is widely used in heat sink material, and copper and mickel is equal
Heat conductivility is high, and nickel matter is harder, has good ductility, magnetic and corrosion resistance, and wherein corronil is famous illiteracy
Alloy like this, heat conduction and heat radiation performance are strong, and intensity is high, and plasticity is good, high temperature resistant, and stable chemical performance, using copper, nickel or corronil
Heat conduction and heat radiation performance, intensity and the chemical stability of composite membrane can be strengthened.
The content of the invention
In order to overcome the deficiencies in the prior art, the present invention provides a kind of mobile phone heat conduction composite membrane, both with excellent heat conduction

It is covered in another surface of the first heat conduction glue-line.
Described polymer-based metal composite film is by metallic and macromolecular material composite molding in a variety of ways
Composite membrane.Described macromolecular material is PETG；Described metallic is copper, nickel or corronil.Described first
Heat conduction glue-line and the second heat conduction glue-line are the acrylate glue for adding copper and mickel.
The invention has the beneficial effects as follows：Using polymer-based metal composite membrane be by metallic（Copper, nickel or cupro-nickel are closed
Gold）With a kind of Novel composite membrane of macromolecular material PETG composite moldings in a variety of ways.Composite molding instead of and use gluing
Agent is pasted, it is to avoid adhesive excessively hinders heat to conduct, copper, nickel or corronil good heat conductivity, intensity is high, plasticity is good,
Stable chemical performance and high-low temperature resistant, PETG have more prominent pliability, high impact strength, excellent resistance to chemical attack
Property, high grade of transparency glossiness and anti-scratch colored performance, excellent in weather, the compound of the two can make heat conduction composite membrane not only heat conductivility
It is good, and have both pliability and shock resistance, it is easy to production with storage；The alternative high cost of polymer-based metal composite membrane
Graphite radiating material, cost are relatively low, when being covered on mobile phone thermal component surface, compared with high-low temperature resistant and chemical corrosivity, use
Life-span length；For the acrylate glue containing metallic, metallic is copper and mickel to the heat conduction glue-line for adopting, and this had both improve prolongation
The heat conductivility of property, and the heat conductivility of thickness direction is improve, be conducive to the quick transmission of heat.It is logical using PETG films
The two sides that heat-conducting glue is pasted onto polyalcohol group compound film is crossed, in shaping, cross cutting, support is played to polyalcohol group compound film and is made
With coiled material can be wound into, and when using, PETG films are peeled off, mobile phone is attached at and is treated heat-delivery surface.Cull is avoided, favorably
It is uniform in radiating.PETG films can also keep the toughness of product.It contains ultra-violet absorber, can co-extrusion into one protection
Layer, protects product from the adverse effect of ultraviolet.And there is during transport and use enough ability to bears, have
Help prevent rupture.
