Description
Technical field
The invention belongs to the preparation method of polyethylene/ethylene-propylene rubber(EPR)/carbon black conductive polymer matrix material.
Background technology
Along with the fast development of electronic technology and popularizing of electronic product, the needs of conducting polymer composite grow with each passing day, and range of application constantly enlarges.According to the difference of conduction essence, conducting polymer composite can be divided into structure-type (or being called eigenmode) and compound two kinds.The structural conductive macromolecular material self has conducting function, as polyaniline, and polyacetylene, polypyrrole etc.But such conducting polymer composite is popularized so far as yet owing to have many difficult problems in batch process and application facet.Means such as conductive polymeric composite then is a method of utilizing mechanical blending, and is compound through disperseing by add conductive filler material such as metal-powder, steel fiber, carbon fiber, carbon black in macromolecule matrix, and lamination is compound are given the material conducting function.Compare with the structural conductive macromolecular material, conductive polymeric composite has the advantages that cost is low, technology simple, be easy to machine-shaping.
Electrical conduction mechanism is: be owing to be in contact with one another the formation conductive channel between the carbon black particle on the one hand; Be owing to the carbon black particle quantity not sufficient on the other hand, when voltage, electronics can lean on the tunnel effect conduction.In fact, in the polymer composite conducting process, these two kinds of mechanism are simultaneous, just the efficient difference of conduction.
For carbon black-filled conductive polymer matrix material, in order to obtain good electrical conductivity and to make polymkeric substance have comprehensive premium properties, select superconductive carbon black on the one hand, be the compounding technology at interface on the other hand.Handle the carbon black particle surface for the compound common employing silicane in interface, titanate ester or aluminium esters of gallic acid coupling agent, make to form good interface between itself and polymkeric substance and cohere, and improved the compatible and dispersing property of carbon black particle and matrix.The molecular characterization of these coupling agents shows as end parent superpolymer, the other end parent carbon black particle.The material that adopts this coupling technology to obtain, the electroconductibility that when the weight percent of carbon black in material is above above 10%, just can show.
The result of study that F.Gubbels was published on the Chem.Mater. in 1998 shows, in the conductive polymer matrix material that with the Polymer Blending System is resin matrix, carbon black forms conductive network easily on the interface, help to improve the conductivity and the mechanical property of compound system.2. black carbon surface is carried out effective modification to improve the consistency of polymkeric substance and carbon black, improve conductive stability.The result of study that people such as Fujiki are published on the Polym.J. shows, through monomeric graft polymerization reaction reactive group is guided to black carbon surface and can obtain the good interface modified effect, the electroconductibility of material is increased substantially, and conductive stability also improve.But the cost of this interface modification method is higher, complex process.
