Reaction conditions: temperature of reaction is 3 DEG C, the mol ratio of oxygenant and aniline monomer is 1:1, and reaction medium is 1mol/L hydrochloric acid soln, and 1mL aniline is to 9g silicon-dioxide.
Silicon-dioxide is added in three different ways: (1) is according to aniline monomer preadsorption method of the present invention under above polymerizing condition, namely first with ethanol, aniline is diluted, and with this solution impregnation silicon-dioxide, then put into baking oven toast within 0.5 hour, make ethanol volatilize totally, then aniline can be attached to silica particles, put into acid medium again, add oxygenant and be polymerized; (2) aniline monomer directly joining method, namely directly joins in reaction medium by aniline, stirs 5min and makes it to mix, add oxygenant and be polymerized; (3) blending method after aniline polymerization, namely first carries out chemical oxidising polymerisation by aniline under existing without silicon-dioxide, polymkeric substance add silicon-dioxide and stir.
These three kinds of methods obtain PANI coated silica mixture specific conductivity list in table 1.Can be seen by table 1, after aniline polymerization, blending method products therefrom color is more shallow, and specific conductivity is low, and aniline monomer preadsorption method can obtain the black composite of the highest specific conductivity.
The specific conductivity of gained PANI coated silica mixture and knifing color under table 1 aniline monomer three kinds of feed postition
Embodiment 2:
In embodiment, reactions steps is as follows:
(1) the pre-attachment of aniline monomer: first with ethanol, the derivative of aniline and aniline is diluted to aniline solution, and infiltrate gas phase nano silicon-dioxide with this aniline solution, after infiltrating, gas phase nano silicon-dioxide is put into baking oven and is baked to ethanol volatilization totally, and the rear gas phase nano silicon-dioxide of baking is put into acidic medium again and stirred;

Feed than having synthesized the different PANI coated silica anticorrosive additive of four kinds of polyaniline PANI content from silicon-dioxide according to above step four kinds of different aniline, their specific conductivity is in table 2.
The PANI content of table 2PANI coated silica mixture and the specific conductivity of mixture
Can find out, along with the increase of aniline add-on, product specific conductivity rises gradually, when aniline content is below 10%, specific conductivity ascendant trend is obvious, increase in the order of magnitude, and when aniline content is more than 10%, specific conductivity ascendant trend reduces, particularly the coated product of PTSA doping state is when aniline content is more than 10%, conductivity variations is little, therefore considers from the angle reduced costs, and the proper consumption of aniline monomer is 20%.This ratio and the calculated results differ greatly, and are nonconducting according to the coated product that Theoretical Calculation ratio obtains.This is because silica dioxide granule is comparatively large, particle diameter is tens times of individual layer PANI thickness, if only have individual layer PANI to be coated on particle surface, the volume ratio of PANI shared by particle is too small, and cannot realize good electroconductibility, therefore specific conductivity is very low.And when the mass ratio of silicon-dioxide and aniline monomer is 9:1, the volume ratio shared in particle of PANI is comparatively large, therefore higher specific conductivity can be obtained.
The size distribution recording PANI coated silica mixture is tested to aniline monomer consumption embodiment product LS230 type laser particle size analyzer (Beckman Coulter Inc. of the U.S.) that is 10% and sees Fig. 1, coated front and back grain size distribution curve shape is basically identical, grain size distribution curve after PANI is coated there occurs translation than coated front curve to Large stone direction, proves that coated rear particle entirety becomes large.Silicon-dioxide median size is 2.51 μm, and PANI coated hum silicon dioxide silicon compound median size is 3.27 μm.If according to spherical coated calculating, coating thickness is about 380nm.In addition, if there is the PANI particle of " dissociating " in coated product, then generally there will be two peaks in coated particle size distribution curve, be respectively PANI coated silica mixture particle distribution peak and PANI particle distribution peak, and not discovery second peak in the coated particle size distribution curve recorded at us, this demonstrate PANI and be all coated on silica particles, do not form the PANI of " dissociating ", and more even at the coated Thickness Ratio of silica particles.

Embodiment 4:
Gained doping PANI coated silica in embodiment 2 is moved in beaker, add ammoniacal liquor magnetic agitation 24h, filter, use a large amount of distilled water washs to neutral again, filter, must remove doping state PANI coated silica, will the PANI coated silica mixture tosic acid PTSA aqueous solution adulterated be gone to adulterate, doping consumption is the mol ratio of each structural unit and tosic acid in PANI be 1:0.7.Obtain the PANI coated silica mixture of cyan tosic acid doping.Its specific conductivity is in table 2.After visible doping, the specific conductivity of mixture all has raising in various degree, but the specific conductivity that aniline monomer consumption is the mixture of 20% slightly declines.
When adulterating again with PTSA, if use the alcoholic solution of PTSA to adulterate again, about 7 times in the aqueous solution that the mixture specific conductivity then obtained is, this be due to polymer molecule long-chain in ethanol form more unfold, group steric hindrance is less, PTSA is more easily doped on molecular chain, thus obtains effect of better adulterating.Therefore, when PANI coated silica mixture adulterates again, application uses ethanol to make medium.
Embodiment 5:
PANI coating being carried out the aftertreatment such as drying, grinding, it can be used as anti-corrosion function component to join priming paint as formed coating system in the filmogens such as urethane (PU) polyacrylic ester, its formula is in table 3.
Table 3 has the primer base formula of anti-corrosion function
Cold-rolled steel sheet base material respectively carries out the simultaneous test of three groups of coating:
1) blank coating, namely directly sprays two-layer PU varnish on base material;
2) pure hum silicon dioxide silicon coating, namely uses without coated silicon-dioxide as anti-corrosion function priming paint, then sprays one deck PU varnish as finish paint;
3) coated hum silicon dioxide silicon coating, the micron silica namely using PANI coated as anti-corrosion function priming paint, then sprays one deck PU varnish as finish paint.
According to above-mentioned 3 kinds of modes, by paint spay-coating on tinplate and cold-rolled steel sheet, put into 60 DEG C of oven for drying, coat-thickness about 50 μm.Paint film intersects and draws two cuts, cut place air directly can contact with base material.Put it into salt fog cabinet and carry out corrosion test, salt fog condition is ASTM B117, namely constantly on plate, sprays the NaCl salt solution that 35 DEG C of concentration are 5%, takes out and observes its corrosion condition, see Fig. 3 ~ Fig. 5 after 200h.The antiseptic power grade of naked eyes objective evaluation coating is carried out according to table 4.
The corrosion situation corresponding to each corrosion level of table 4 sets itself
Can see not having the plate at the coating place of anticorrosive additive of the present invention has all occurred yellow rust staining at cut place, and the plate that with the addition of the coating place of anticorrosive additive of the present invention does not observe rust staining.According to the anticorrosion grade of coating in table 5 in table 5.Can be seen by table 5, the plate at PANI coated hum silicon dioxide silicon compound corrosion protection coating place does not corrode completely, and other plate all there occurs corrosion, and pure silicon dioxide coating is more serious than the corrosion condition of blank coating.This is because add the adhesive ability that pure silicon dioxide particle can reduce coating in coating, make the shielding effect of coating be deteriorated, thus preservative property are deteriorated; But add after PANI coated silica mixture makes protective system in coating, PANI coated silica mixture forms continuous print conductive layer at matrix surface, this conductive layer and metallic contact, form the oxide film of one deck densification, i.e. passive film, this tunic can prevent metal below from corroding further, thus reaches anticorrosion object.
