Detailed description of the invention
In order to illustrate more clearly of the technical solution of the application, letter will be made to attached drawing needed in the embodiment below
Singly introduce, it should be apparent that, for those of ordinary skills, without any creative labor,
It is also possible to obtain other drawings based on these drawings.
Fig. 1 is a kind of flow chart of the preparation method of composite conducting foaming agent material provided by the present application.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Whole description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
For a long time, high molecular material is very popular by its excellent performance, but people always return high molecular material
For insulating materials, until the doping type polyacetylene (Poly acetylene, PA) that Hideki Shirakawas in 1977 and Mac are studied can
This traditional idea is just broken after electric conductivity to reach bismuth metal, then, the new term for academia occur is " conductive high
Molecular material ", meanwhile, its discovery and development creates a novel cross discipline --- conductive polymer subdomains.Later
People have found that polyaniline, polyphenylene sulfide, polypyrrole, polythiophene etc. also have similar metallic conductivity in succession again, although leading
The research and development of electric high molecular material start to walk compared with Dinner, but it has lighter weight, the available simple and easy methods such as casting, molding of peeping form, are easy to
Synthesis and carry out Molecular Design, raw material sources than it is wide the advantages that so that in recent years, conductive ion molecule receives generation
The favor of the large quantities of researchers in various countries of boundary, also achieves significant progress.
Conductive polymer material generally can be divided into structural type and compound two class.Structural conductive macromolecular material, such as
Polyethylene, although having the conductivity close to copper, since its environmental stability problem is not resolved always, application foundation
The Comparision for studying aspect is weak, later in order to overcome environmental stability poor, and the polypyrrole, polythiophene, poly- occurred in succession
Aniline and its derivative have become the principal item of conducting polymer.The nineties, part-structure type conductive polymer material is
Into practical stage, but in view of the shortcomings that its own and its material is limited by factors, structural conductive macromolecular material
The market occupied is still very limited.In contrast, conductive polymeric composite is then quickly grown, and is widely used in medicine
Engineering, electromagnetic shielding material, absorbing material, photoelectric material, anti-static material, anti-corrosion of metal material, gas sensitive, electrochromism
The exploitation and application of the materials such as material.Compound-type conducting material is that a certain number of lead is added using high molecular polymer as matrix
The material that isoelectric substance is made up of different combination process has the processability of high molecular material and the electric conductivity of metal concurrently.With
Metal phase ratio, compound-type conducting material has good processability, simple process, corrosion-resistant, resistivity adjustable extent is big, price is low etc.
Advantage.
The phenomenon that carbon black/PE composite material shows ptc characteristics is Frydman1945 first discovery, but until
1966, Kohler was mixed with LDPE with carbon black, and after obtaining obviously PTC effect, this phenomenon just causes widely to close
Note, and put into the research and development to this material.Conductive foaming agent is and pure as one of carbon black/PE composite material
Polymers Phase ratio, it has many valuable performances.Such as, density is small, specific strength is high, has the ability, heat-insulated for absorbing impact load
Property is good, sound insulation capabilities are strong.And in foaming process, the special cellular structure of foamed material can be to nanofiller mechanism of action
It is relocated, to control in foaming material charge level and conductivity therethrough, and then instructs its application range.Therefore,
Conductive foaming composite material may be applied to the numerous areas such as automobile or electronic product as novel substitute products at present.
Although normal metal material conducts electricity very well, but quality is excessive, if biggish conductive member all uses
Metal material is made, then will cause various difficulties such as transport, maintenance, installation and disassembly, therefore, it is necessary to use a germplasm
Light and conductive substance partially to replace metal material.
