Description
Technical field
The invention belongs to Material Fields, and in particular to a kind of recycling waste aluminium plastic packaging material is to prepare high heat conductive insulating material
Composite material prepared by the method and this method of material.
Background technology
Aluminium plastic composite packaging material with its high barrier property, light blocking, paracentesis resistance and it is of low cost the features such as, by generation
Various countries of boundary are widely used in food, drug, electronics and national defence highly sophisticated products packaging field, and annual all significantly incremental.Aluminium
Modeling laminated film mainly has PP (polypropylene)/aluminium, PE (polyethylene)/aluminium etc., is used for various food packagings, and process neutralization makes
Waste aluminium plastic composite membrane after is a kind of metal/high-molecular material, and metal and polymer material are completely embedded, and separation is difficult,
Recovery utilization rate is low.The demand of China's aluminum-plastic packaged material every year is more than 8,000,000 tons, and is increased with annual 20% speed,
The annual discarded amount of conservative estimation is more than 2,000,000 tons (Chinese packaging industry statistical reports in 2015).Currently, main processing ways
To burn and filling (AK Kulkarni, S Daneshvarhosseini, H Yoshida.The Journal of
Supercritical Fluids, 2011,55,992-997), the aluminum-plastic packaged material that Ye You foreign studies mechanism has been reported that
Recovery technology, core are isolation technics, mainly there is mechanical phonograph recorder separation and fractionation.Mechanical phonograph recorder separation refers to passing through machinery
Force effect detaches aluminium foil and plastics, the method be difficult by plastic-aluminum aluminium foil and plastics be kept completely separate (Yan D, Peng Z, Liu
Y,Li L,Huang Q,Xie M,Wang Q.Waste Management,2015,35,21-8)；Chemical-solvent method refers to using
Solvent removes the metal of polymer surfaces, under generally use weak acid or aqueous slkali high temperature boiling oxidation reaction occurs with aluminium foil, break
Binding force between bad plastic-aluminum realizes aluminium foil and plastics separation.The method is of high cost, difficult solvent recovery, and environmental pollution is serious
(SamorìC,Cespi D,Blair P,Galletti P,Malferrari D,Passarini F,Vassura I,
Tagliavini E.Green Chemistry,2017,19,1714-1720.).Chemical cleavage method refer under oxygen-free environment,
Polymer cracking is realized aluminum-plastic separation by high temperature.The method equipment investment is big, high energy consumption, generates toxic and harmful gas.Studies in China
Be concentrated mainly on solvent separation, burning method take aluminium (Hu Y, Bakker MC, PG de Heij.Waste Management,
2011,31,2422-30), but effect is not ideal.Therefore, development environment close friend, high-qualityization recycle waste aluminium plastic packet
The technology of package material is still industry development development urgent problem to be solved.But at present about recycling waste aluminium plastic packaging material,
The technology for using it for preparing high value-added product is rarely reported both at home and abroad.
On the other hand, as the integrated of electronic component, micromation and high performance, the heat dissipation of electronic product become
The problem of one great challenge.Result of study shows that the running temperature of electronic component often improves 10-15 DEG C, and the service life will decline one
Half (H Im, J Kim.Carbon, 2012,5429-5440.), therefore it is electronics industry development to research and develop high-performance heat sink material
One of bottleneck.The heat sink material thermal coefficient of mainstream is more than 1W/mK at present, and mainly by polymeric matrix, (thermal coefficient is small
In 0.4W/mK) addition high-content (50-70wt%) heat filling preparation.Need material that there is excellent insulation performance simultaneously, because
This, insulating ceramics powder such as Al2O3, AlN, SiC and BN be widely used in production heat-conducting plastic, conventional ceramic heat filling is mostly
Random particle cannot form effective thermal conducting path under low content, and product thermal coefficient is caused to promote limited extent, therefore in order to
Meet the heat dissipation performance for leading material, the content of inorganic filler must be over 50wt%, and the system of composite material is not only significantly increased in this
This is caused, the processing performance and mechanical property of serious deterioration material are gone back.Sheet heat filling such as graphene and BN etc. are in recent years
Research hotspot easily form effective three dimentional heat conduction network since sheet heat filling piece interlayer can be overlapped mutually, can effectively improve
The heat conductivility of plastic products.But graphene is of high cost, dispersion is difficult, and at low levels (<It can 5wt%) be formed conductive logical
Road, conductance are more than 10-6S/cm, it is difficult to meet requirement of the electronic product to insulation performance.Sheet BN ceramic powders can be used for preparing
High heat conductive insulating product, but problem of high cost is also faced, there is not it to be commercialized the relevant report of large-scale application.Therefore, it opens
Novel low-cost sheet heat-conductive insulation filling is sent out, is aoxidized especially by discarded sheet metal and prepares sheet insulating heat-conductive filler
The relevant technologies are expected to provide new approaches, new way for the preparation of High-heat-conductiviinsulation insulation material.
Aluminum layer thickness in waste aluminium plastic composite membrane is micron-scale, if aluminium surface to be oxidized to the aluminium oxide of nanostructure
Layer, can be used as novel heat-conducting insulating packing.It is further mixed with high heat conduction graphite or nano graphite flakes, forms nano aluminium oxide
The three-dimensional filler network of piece/nano graphite flakes high heat conductive insulating is expected to prepare high heat conductivity insulation composite.
