Description
Technical field
The present invention relates to a kind of metal surface anticorrosive paint and preparation method thereof, metal is applied to more particularly, to one kind
The anticorrosive coating of surface especially copper metallic face, while also disclosing the preparation method of the anticorrosive coating.
Background technology
Corrosion of metal is metal by surrounding medium chemistry or electrochemical action and destroyed phenomenon.The corruption of metal
Erosion brings huge loss to national economy throughout national economy every field.In the country of industry prosperity, corrosion is caused
Direct economic loss account for the 1%~4% of total value of production in national economy, the steel of annual rust corrosion accounts for the 20% of yield, about
The equipment for having 30% is scrapped because of corrosion.In China, the economic loss caused due to metal erosion every year up to 30,000,000,000 yuan with
On, account for the 4% of gross national product.Metal coating corrosion-resistant is applied widely, such as epoxy used in the shell of ship
Cold coating.And the research of anticorrosion coating material only play the physical isolation effect of coating from initial passive antisepsis,
Prevent metal substrate from directly being contacted with corrosive medium in environment, the passive anti-corrosion developed into now is combined with Active Anticorrosion, i.e.,
When coating is by destroying, antisepsis of taking the initiative can be continued, reduced by protection corrosion of metal speed.As first by actively
Preservative is coated in the carrier, then by this support dispersion in coating, on the one hand anticorrosive can be avoided unnecessary
Waste, on the other hand this carrier possesses certain environment-responsive, when coating by external environment is stimulated (such as PH change
Change, illumination of temperature etc.), or coating surface be destroyed, such as mechanical damage when, discharge anticorrosive such as corrosion inhibiter
Deng this composite coating is commonly referred to as intelligent anticorrosive composite coating.
Metallic copper and its alloy have higher intensity, good electric conductivity and thermal conductivity, if but metallic copper be in
When in the etchant solution containing ion (such as chlorion, sulfate ion etc.), easily occur spot corrosion and (locally go out in metal surface
The corrosion aperture now developed in depth and breadth.The copper surface upper coating of covering is as one of important method of anti-corrosion of metal, wherein using containing
The coating of chromate is maximally effective anti-corrosion method, but is due to that it has severe toxicity and carcinogenicity, and many countries have prohibited at present
Only use the coating.Therefore, domestic and international researcher is finding the substitute of chromate, there is inorganic compound, such as decorations salt, aluminium
Acid, phosphate etc., in addition also organic inhibitor, such as benzotriazole and its derivative, imidazolines, benzo thiophene
Azole compounds etc..It is a large amount of it was verified that hybrid corrosion inhibitor benzotriazole and its derivative is to the anticorrosion ability ratio of copper
More satisfactory, using than wide, its mechanism of action is to form the complex compound of one layer of BTA and copper ion on copper surface
Diaphragm, and also the diffusion of water and oxygen in water to metal surface can be prevented in cathode filming in anode film forming,
Reduce the corrosion rate of copper.
As it was previously stated, as the change of extraneous corrosive medium is, it is necessary to which corrosion inhibiter can be discharged into by corrosion failure longer
Region, relatively effective method is that corrosion inhibiter is added directly into coating, and what coating was primarily served is the effect of physical barrier.
However, this method being directly incorporated into can not sometimes play enough protective effects, corrosion inhibiter is directly contacted with coating, big
In most cases, this system does not possess the ability that stimulating responsive discharges corrosion inhibiter, if the dissolving of corrosion inhibiter in the coating
When degree is higher, the corrosion inhibiter of quick release can cause coating to occur foaming phenomena, and can destroy the integrality of coating.

200ml, reaction temperature is maintained at 85-90 DEG C, and styrene is very slowly instilled for 0.04g/min speed according to rate of addition
0.5 parts by weight are finally slow again then with the pH value of sodium hydrate aqueous solution (10wt%) regulation reaction solution to 10 or so
The parts by weight of styrene 15 are instilled, time for adding is no less than 40min, and constant temperature is kept for 85-90 DEG C and continues at least 8 hours, completed above-mentioned
Separated, first washed twice using absolute ethyl alcohol by centrifuge after step, after be washed with deionized more than three times, be placed in
Dried 24 hours in 50 DEG C of air dry oven, obtain being coated with the polymer nanocomposite microparticle of BTA.
