This method is simple and low cost fit to industrial production. The product also has well film-forming and leveling properties and fit to anti electromagnetism or EL material.
Description
Technical field
The present invention relates to the preparation method of a kind of protective system with epoxy/polyaniline composite base-material.
Background technology
At present, worldwide carrying out the research that a large amount of relevant polyanilines is synthetic and use.But polyaniline is as conducting polymer composite, because its raw material is easy to get, good conductivity is stablized in environment, is considered to be hopeful most to obtain the superpolymer of practical application.But it is difficult to dissolving, it is reported that it can only be dissolved in such as minority intensive polar solvents such as formic acid, dimethyl formamide, dimethyl sulfoxide (DMSO); It can not fusion, just decomposes about 200 ℃; It is very poor with the blend of other materials, above effects limit its processing and application.Therefore, the study on the synthesis of the modification of p-poly-phenyl amine and function mixture thereof becomes hot fields.
Polyaniline film has very strong anti-corrosion function to metal.It is generally acknowledged that polyaniline has certain redox potential, it makes the surface of iron and steel that oxidation take place, and reaches the passivation potential of iron, makes the Fe of surface generation one deck densification of iron
3O
4Zone of oxidation has stoped the further oxidation of iron.Therefore polyaniline anti-corrosive paint, the especially exploitation of epoxy fundamental mode polyaniline anti-corrosive paint and applied research have caused people's extensive concern.
Resins, epoxy has excellent characteristic such as good cementability, low-shrinkage, chemical proofing, therefore is widely used as the film forming base of polyaniline anti-corrosive paint.
Protective system has following several method: 1. at first at inorganic filler surface polymerization polyaniline, this type of filler is mixed with Resins, epoxy, as patent CN1401718A usually with the preparation of epoxy/polyaniline composite base-material again at present; 2. at first prepare the polyaniline dispersion liquid, again with the blend of epoxy resin film forming matter, as patent CN1215744A; 3. the described method of patent CN1429258A is: at first polyaniline is dissolved in the specific curing agent solution, mixes with Resins, epoxy; 4. with film forming matter blend such as polyaniline powder and Resins, epoxy, as patent: CN1243852A, CN1385486A, CN1358812A, CN1441039A, the drawback of this type of preparation technology's maximum has been to use the polyaniline material for preparing, because polyaniline material not only costs an arm and a leg, and its preparation process exists the problem of all many-sides such as complex process, cost height, environmental pollution.It is the method that dispersion agent prepares the polyaniline mixture with the thermoplastic resin that patent CN1127267A has described a kind of, and the sticking power of the thermoplasticity film forming matter that this method adopted and medium-resistance thermosetting epoxy resin all more of the present invention is poor.
