Dioctyl phthalate second diester（Polyethylene terephthalate, abbreviation PET）, it has preferable chemical stability, higher
Heat resistance, when being heated, thermal deformation is smaller, can keep the stability of physical aspect, and it is radiating that it is widely applied
The mould release membrance or matrix of structure, but another macromolecular material polyethylene terephthalate -1,4-CHDM
Ester { Poly (ethylene terephthalateco-1,4-cylclohexylenedimethylene
Terephthalate), abbreviation PETG }, compared with PET, it 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 widely used in heat sink material due to strong with thermal conductivity factor and heat storage capacity higher, and copper and mickel is equal
Heat conductivility is high, and nickel matter is harder, there is good ductility, magnetic and corrosion resistance, and wherein corronil is famous illiteracy
Alloy like this, heat conduction and heat radiation performance is strong, and intensity is high, and plasticity is good, high temperature resistant, stable chemical performance, uses 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

Nickel alloy）With a kind of Novel composite membrane of macromolecular material PETG composite moldings in a variety of ways.Composite molding instead of and use
Adhesive is pasted, it is to avoid adhesive excessively hinders the heat to conduct, copper, nickel or corronil good heat conductivity, intensity is high, plasticity
Good, stable chemical performance and high-low temperature resistant, PETG have more prominent pliability, high impact strength, excellent chemically-resistant rotten
Corrosion, 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 thermal conductivity
Can be 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 is relatively low, is covered on when on mobile phone thermal component surface, compared with high-low temperature resistant and chemical corrosivity, makes
Use long lifespan；The heat conduction glue-line for using is the acrylate glue containing metallic, and metallic is copper and mickel, and this both improve and prolongs
The heat conductivility of property long, and the heat conductivility of thickness direction is improve, be conducive to the quick transmission of heat.Using PETG films
The two sides of polyalcohol group compound film is pasted onto by heat-conducting glue, 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, it is attached at mobile phone and treats 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 enough ability to bears during transport and use, have
Help prevent rupture.
