Description

A kind of conductive engineering plastics
[technical field]
The invention belongs to material chemistry technical field, relate to a kind of conductive engineering plastics and preparation method thereof。
[background technology]
Telecommunications industry is national very important new high-tech industry, closely related with national security and the lives of the people。Macromolecular material is closely related with telecommunications industry。Telecommunications product not only needs substantial amounts of macromolecular material insulator, it is also necessary to extensively use conducting polymer composite。The equipment such as computer, communication network equipment, printer, digitizer can be played the effect of electromagnetic wave shielding by conducting polymer composite, this leakage of information anti-, can be additionally used for eliminating the electromagenetic wave radiation to human body of the said equipment, and be used for reducing electrostatic hazard。Conductive engineering plastics, as the one in conducting polymer composite, is widely used in shell and the photocopier/printer charging wand sleeve pipe of electronic product。
Macromolecule conducting material can be generally divided into structural type and compound two big classes。Common structural conductive material mainly has polyaniline, polypyrrole and polyacetylene, and they can provide conduction to dam son due to the conjugated bonds in macromolecular chain, so himself just has electric conductivity。But this type of material is poorly soluble and melts, it is difficult to molding, simultaneously because production cost is higher, thus limit application。Polymeric matrix in composite polymer conductive material itself is non-conductive, relies on the carbon system such as metal system filler, white carbon black (conductive carbon powder) the filler conductive materials such as the metal alloy oxide adding conduction to obtain conductive characteristic。Owing to this type of material not only remains machinery and the mechanical property of usual macromolecular material, the electric property of adjustable material simultaneously, there is easy-formation, the advantage such as less costly。
Conductive carbon powder filled-type conducting polymer composite is one comparatively conventional in current composite conductive polymer。Why packing carbon powder type conducting polymer is widely adopted, firstly because a kind of natural quasiconductor of conductive carbon powder, its specific insulation is 0.1~1000 Ω .cm, and aboundresources, cheap, the suitability is strong;Secondly because carbon dust can significantly improve the electric conductivity of material, and carbon dust electric conductivity lasting stability, and easily process, macromolecule there is is potentiation。But along with conductive carbon powder fills the increase of deal, the electric conductivity of polymer also increases, after filling deal exceedes certain value, its electric conductivity has qualitative leap。Conductor is become, this value and percolation threshold from insulator。But, when the loading of conductive carbon powder increases, can seriously reduce high molecular mechanical performance。Therefore the standard weighing conductive carbon powder filled-type electric conductivity quality is: first wants can improve polymer conductivity while, can keep again other performances such as good mechanical performance, glossiness;Second to have relatively low percolation threshold, takes into account the cost performance of compound-type conducting composite。But, although carbon black filled nylon conducting polymer conventional at present can reach certain electric conductivity, but its specific insulation is unstable, and mechanical performance is poor, and its surface is comparatively coarse, it is easy to " dry linting " phenomenon occurs, limits its range of application。
So novel conductive engineering plastics all utilizes metal system filler that macromolecule matrix material is carried out uniform filling, to improve the material of its electric conductivity。Conventional conductive metal alloy oxide has indium tin oxide target, zinc oxide aluminum, tin-antiomony oxide etc., these conductive metal alloy oxides are filled and are made plastics have high conductivity in the plastic, conductive metal alloy oxide proportion in the plastic is more big, the conductive effect of plastics is more good, micron-sized conductive filler was added in the past and plastics were put extruding pelletization in an extruder, owing in plastics, the interpolation of inorganic matter makes the mechanical strength of plastics reduce, the poor performance of counter-bending antitorque folding, shock resistance against pressure is deteriorated, then people begin one's study and add in organic plastics by nano level conductive metal alloy oxide, but add to due to nano level inorganic filler and organic plastics are difficult to make nano level inorganic filler well be disperseed, nano level inorganic filler is easily reunited together, cause the deterioration in physical properties of conductive engineering plastics。
