The minimum film formation temperature of emulsion coatings can be reduced, coating application performance is improved；During coating, there may be foam production
It is raw, therefore proper quantity of defoaming agent is added and eliminates out foam；Auxiliary material of the invention is compound rare-earth, due to the metal of the above rare earth element
Atomic radius is big and rare earth activity with higher, it is easy to the gap of storeroom is filled up, meanwhile, rare earth element is easily and oxygen, sulphur
Equal element compounds generate the high compound of fusing point, and the addition of compound rare-earth improves the dispersibility for preparing coating to a certain extent
And compatibility, so that product mix is uniformly also improved the anti-flammability of coating.
Deionized water is used when prepared by modifying epoxy resin by organosilicon of the present invention, the performance of coating obtained by the purity of water has one
Fixed influence contains a little metal ion in tap water, can cause the polycondensation reaction between hydrolysate silanol, thus to product
The performance of coating generates adverse effect, and the performance of side effects coating will not be generated using deionized water.
The present invention is not limited using thermal spraying aluminium layer method by scantling, and simple process is flexible, and arc spraying zinc aluminum
Very good solution fogging problem, hot jet coating surface have certain micropore, do so reusing neutral paint to aluminized coating
Seal treatment makes steel construction obtain safer anti-corrosion protection, while neutral paint is used as priming paint, it does not rise with aluminized coating anti-
It answers, and can preferably be combined in aluminized coating and finishing coat；The present invention forms electrode potential in apparatus surface using arc spraying aluminium
Lower than metal layer, when surface has electrolyte to constitute corrosion cell, source current flows to steel substrate from coating, as a result coating
Corroded and the cathodically protected effect of matrix.
Construction technology of the invention can reduce the temperature of coating, reduce that coating temperature is excessively high to have an impact device, improve
Apparatus surface quality, prolongs the service life.
