Washed 2-3 times with absolute ethyl alcohol, decompression spontaneously dries overnight after filtering, then is dried with 60-70 DEG C of air dry oven, obtains thin,tough silk cloud
Mother-Polyaniline；
（2）Diethylenetriamine is added in reaction vessel, opens stirring, it is 200-250r/min to control stir speed (S.S.), rise temperature
Degree starts that the octyl glycidyl ether of 0.75-0.85 times of parts by weight is added dropwise, controls and be added dropwise in 3-4h to 45-50 DEG C,
Temperature is raised to 65-70 DEG C, continues magnetic agitation reaction 3-4h, reduces temperature to room temperature, obtain curing agent；
（3）By epoxy resin E571 and deionized water with 1：0.7-0.72 mass ratio mixing, after mechanical agitation is uniform, adds thin,tough silk
Mica-Polyaniline, continue mechanical agitation to uniform；Curing agent, DMP-30 and organic silicon defoamer are added, is added
The deionized water of 0.6-0.65 times of parts by weight, continue to be stirred until homogeneous, deaeration, obtain coating；
（4）Coating even application is dried under the conditions of working interface, 60-70 DEG C, obtains the polyaniline epoxy of sericite toughness reinforcing
Resin resistant coating.
The preparation method of the polyaniline epoxy resin corrosion-inhibiting coating of described sericite toughness reinforcing, it is characterised in that step（1）
The mass ratio of middle aniline and ammonium persulfate is 1：0.32-0.35.
The preparation method of the polyaniline epoxy resin corrosion-inhibiting coating of described sericite toughness reinforcing, it is characterised in that step（3）
Epoxy resin E571, sericite-Polyaniline, curing agent, the mass ratio of DMP-30 and organic silicon defoamer are 1：
0.06-0.08：0.75-0.8：0.12-0.15：0.03-0.04.
By using above-mentioned technical scheme, the present invention has the advantages that：
The present invention prepares sericite-polyaniline in the method using mechanochemistry polymerization in sericite surface aggregate polyaniline first
Compound；Then the curing agent with certain flexibility chain is prepared；Finally, using epoxy resin E571 as raw material, with different epoxide numbers
Epoxy resin be mixed into component A, curing agent, accelerator, modified pitch and the mixing of other auxiliary agents, sericite-polyaniline are compound
Thing is toughener, adds curing agent and other auxiliary agents, is mixed, and is applied, and solidification, obtains the polyaniline epoxy of sericite toughness reinforcing
Resin resistant coating.Polyaniline is a kind of novel high polymer material, have cost it is cheap, chemically and thermally excellent in stability, synthesis
The characteristics such as simply, anti-corrosion loss is strong.And epoxy resin then has the characteristics that adhesive force is strong, intensity is high, chemicals-resistant, wear-resisting, sheet
The antiseptic property of the excellent filming performance of epoxy resin and polyaniline is combined by the corrosion-inhibiting coating of invention, and it has preferably anti-
Rotten effect.Sericite is the silicate of scale sheet superfine in muscovite mineral suite, not only aboundresources, it is widely distributed and
It is cheap, and with many excellent performances, such as chemical property is stable, can acid-alkali-corrosive-resisting, and with high resiliency, high-ductility
Property, shielding ultraviolet rays and counter infrared ray radiation etc.；Sericite is added in corrosion-inhibiting coating, on the one hand can substantially reduce cost, separately
On the one hand, in the coating, sericite tends to arrange parallel to coating surface, forms one layer of inert, resist chemical and sun
The protective layer of light radiation, make it that air and moisture can be prevented to enter, can also prevent coating stress from concentrating to produce cracking, improve painting
The critical film Cracking Thickness of layer.Corrosion-inhibiting coating provided by the invention, has that adhesive force is strong, intensity is high, chemicals-resistant, wear-resisting, anti-
The good characteristics such as corrosionization is strong, cost is cheap.
