In be applied.Corresponding to this, the theoretical research of electrically-conducting paint is also developed rapidly, and promote application technology increasingly into
It is ripe with it is perfect.Conductive paint be exactly can be used for spraying a kind of paint dry to be formed after paint film can play conduction effect, so as to shield
Cover the function of Electromagnetic Interference；
Conductive paint makes completely insulated nonmetallic or non-conducting surfaces have as metal by spraying, the method brushed
The feature absorb, conducted and decay electromagnetic wave, so as to play a part of shielding electromagnetic interference.The appearance of conductive paint, effectively
Solve nonmetallic surface and realize the problem of electrically connecting.Conductive paint is to electroplate the anti electromagnetic wave interference paint that silver particles are made, single
Component, saving of labor, time saving, convenient, adhesive force are good, smooth, cohesive force is strong, without loose particle, are base available for metal, composite
The inner walls sprayed on material such as mobile phone, calculator, precision instrument of material.Enamelled coating performance is stable after dry solidification, is sprayed on workpiece
Surface smooth has excellent electric conductivity, fine and smooth conducting particles to ensure that electronic component as fine silver conductive paint
Security.To ensure the adhesive ability of paint vehicle and basal plane, in normal conditions, conductive paint vehicle is only advised using non-in PC, ABS etc.
The surface of metal material, if using on the surface that is of little use, it may be necessary to which bottoming agent is used cooperatively；
The .7 of application number 201410635558, discloses the synthesis of a kind of antistatic coating and preparation method thereof, wherein polypyrrole
Technique is as follows：Respectively by 3,6-4 7g neopelexes, 8.9-9.6g isopropanols, 22. 9-27.0g deionizations
Water adds polymeric kettle, after stirring, and adds 1.2-2.3g ammonium persulfate, then passes to 10.9-13.8g pyrrole monomers, instead
Answer after 4-10h, plus 0.7-1.3g hydroquinones terminators, discharged after cooling, produce polypyrrole conducting polymer latex, it is first
Polypyrrole is prepared, then mixes polypyrrole with inorganic additive, by dispersed with stirring, but inorganic filler is so easily caused
Reunion, each Material Compatibility is poor, so as to reduce the stability_intensity of finished product film.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of fiber reinforced polypyrrole of epoxidation
The preparation method of anticorrosive paint.
To achieve the above object, the present invention uses following technical scheme：

Material, air drying is added in the hydrogen peroxide solution that concentration is 15-20%, and rise temperature is 50-60 DEG C, and insulated and stirred 1-2 is small
When, precipitation is washed, is sent in 40-50 DEG C of baking oven by filtering, is dried 2-3 hours, discharging cooling, obtains hydroxylating fiber；
（2）Take in above-mentioned hydroxylating fiber, the deionized water for being added to 100-120 times of its weight, it is ultrasonic 3-5 minutes, add 1-2
The epoxychloropropane of parts by weight, is sent in 70-80 DEG C of water bath with thermostatic control, insulated and stirred 30-40 minutes, discharging, obtains epoxy fine
Tie up dispersion liquid；
（3）The pyrroles of 150-170 parts by weight is taken, in the absolute ethyl alcohol for being added to 2-3 times of its weight, is stirred, 3-5 weights are added
The triethylamine of part is measured, rise temperature is 70-75 DEG C, and insulated and stirred 1-2 hours is distilled off ethanol, obtains aminated pyrrole；
（4）Above-mentioned epocel dispersion liquid, aminated pyrrole mixing are taken, 20-30 parts by weight, 3-5mol/l hydroxide is added dropwise
It is sent to after sodium, completion of dropping in reactor, insulated and stirred 20-30 minutes at 110-120 DEG C, discharging, must alkalize crosslinking pyrrole
Cough up solution；
（5）Alkalization crosslinking chromium solution is taken, is sent in reactor, nitrogen is passed through, regulation temperature of reaction kettle is 4-6 DEG C, insulation
Reaction 4-5 hours, is discharged, and precipitation is washed in filtering, is dried 20-23 hours at 70-75 DEG C of vacuum, is cooled to normal temperature, produces institute
State the fiber reinforced polypyrrole anticorrosive paint of epoxidation.
Advantages of the present invention：
Then pyrroles is handled first by hydroxylating fiber epoxidation, obtains aminated pyrrole, then by the present invention by triethylamine
By aminated pyrrole and epoxidation fiber blend, it is crosslinked in the basic conditions, obtains crosslinking chromium solution, be finally crosslinked with fiber
