Description
One, technical field
The present invention relates to the corrosion of metal protection.Furtherly, the present invention relates to use organic coating protection metal, make it avoid corruption and touch.Specifically, the present invention relates to a kind of protection against corrosion priming paint of heavy metal and method for making of the finish paint that matches of priming paint therewith of not containing.
Two, technical background
Corruption takes place and touches in metal products such as aircraft, vehicle, boats and ships and various hardware in environment, cause extremely enormous economic loss.The application organic coating slows down corruption and touches speed, the protection metal, and existing permanent history is the preventing metal corrosion method of generally using.
For reaching etch-proof purpose, must contain anticorrosive additive in the organic coating.The most effective anticorrosive additive is heavy metal compounds such as chromium lead now, their serious environment pollutions.Though developed many nontoxic anticorrosive additives, as aluminium triphosphate and various phosphoric acid salt corrosion-inhibiting pigments etc., their Corrosion Protection is also less than the anticorrosive additive that contains heavy metals such as chromium lead.
No matter nontoxic anticorrosive additive still contains the anticorrosive additive of heavy metals such as chromium lead, all is to make an addition among the priming paint.The present invention adds nontoxic anticorrosive additive in priming paint and finish paint.The non-toxic anticorrosion erosion additive that adds priming paint is a polyaniline.The non-toxic anticorrosion erosion additive that adds finish paint is the nontoxic additive of tool cation exchange capacity (CEC).
Last century, the eighties found that conducting polymer (polyaniline) has the effect of preventing metal corrosion.Polyaniline might be more effective than compounds such as chromium lead as anticorrosive additive, is expected to replace the widely used now anticorrosive additive that contains heavy metals such as chromium lead.Two develop industrial polyaniline anticorrosion paint during the last ten years, are subjected to extensive attention always.
Polyaniline cooperates with other component as anticorrosive additive, makes protection against corrosion priming paint.Chinese patent CN 1243852A, CN 1358812A, CN 1401718A, CN 12157644A, CN 1182213C, CN1903956A, CN 1803951A, CN 101314697A etc. match polyaniline with Resins, epoxy etc.
CN 1752160 has adopted two kinds of diverse ways to prepare the polyaniline anticorrosion lacquer: first method is first synthesized polyaniline, then polyaniline is mixed with aluminium triphosphate, various phosphoric acid salt corrosion-inhibiting pigment and polyvinyl butyral solution, be mixed with the A component, phosphorous sour water of B component and alcohol, A before the brushing, B two components are mixed in proportion.Second method is to mix with aluminium triphosphate, various phosphoric acid salt corrosion-inhibiting pigment and polyvinyl butyral solution without polymeric aniline, to be mixed with the A component, and the B component also contains chromic acid class oxygenant except that phosphoric acid, water and alcohol.A before the brushing, B two components are mixed in proportion.After the mixing, under the effect of chromic acid class oxygenant, the aniline in the A component becomes polyaniline on institute matel coated surface in the B component.
Check paint film Corrosion Protection method in common is a salt-fog test.For priming paint, the sticking power between it and metallic surface, the impact resistance of paint film and snappiness all are the important techniques indexs.An industrialized painting, essential through sticking power, impact strength, snappiness, and test such as salt-fog test.CN1752160A is applied to polyaniline priming paint on the tinplate sheet, is coated with one deck alkyd resin enamel again after doing, and has measured sticking power with drawing the circle method.Do not see that as yet other Chinese patent has the polyaniline of mensuration priming paint sticking power, impact resistance, reaches flexible report.CN 1639278A, CN101368055A have measured polyaniline paint Corrosion Protection with salt-fog test.
Three, summary of the invention
The invention provides a kind of method for making of protection against corrosion paint.The priming paint and the finish paint of this protection against corrosion paint all contain anticorrosive additive.The contained anticorrosive additive of priming paint is a polyaniline, and the contained anticorrosive additive of finish paint is the nontoxic additive with cation exchange capacity (CEC).
The invention provides a kind of method for making that contains polyaniline anticorrosion priming paint.This priming paint is applied on the cold-rolled steel sheet, and good cohesive force is arranged, impact resistance and snappiness.The summary that contains polyaniline anticorrosion priming paint method for making is: make aniline by base material, filler, and the material formed such as solvent in polymerization.Base materials employed is polyvinyl butyral, Resins, epoxy etc.Used filler is talcum powder, titanium dioxide, ground barium sulfate etc.Solvent for use is single alcoholic solvent (ethanol, Virahol, butanols) or their mixture.
The present invention provides the method for making a kind of and finish paint that polyaniline priming paint matches simultaneously.Salt-fog test shows that this finish paint and the above-mentioned polyaniline priming paint that contains are used, and antiseptic property is good.The summary of the finish paint method for making that matches with polyaniline priming paint is: with cationic exchange pigment (as the silica gel of calcium ion-exchanged) or Zeo-karb, with other macromolecule resin, filler, and solvent etc. mix, be made into finish paint.Used other macromolecule resin comprises Resins, epoxy, aminoresin, urethane resin, Synolac, acrylic resin, vibrin, fluorine resin and synthetic rubber coating etc.Whether use selecting for use of solvent and agent solvent, get main determining in adopting which kind of resin.
