Abstract
The present invention provides a kind of coating, comprising: 10%-40% modified epoxy, 8%-15% alkyd resin, 5%-12% phytic acid, 5%-10% phosphoric acid, 10%-30% trbasic zinc phosphate, 5%-10% diatomite, 5%-10% micaceous iron oxide gray, 1%-2% dispersing agent, 1%-3% drier, 3%-8% ethyl alcohol and 3%-8% isopropanol.The present invention has prepared a kind of band rust brushing paint that can quickly and efficiently convert iron rust and durable by the way that above-mentioned various fillers are added in modified epoxy according to a certain percentage.Present invention can apply to the secondary corrosion protection system of corrosion structure part, it can make to corrode the finer and close high-molecular coating of part surface formation, slow down corrosive medium and penetrate coating and metal material contact.
Description
Technical field
The present invention relates to field of compound material, specifically, a kind of coating.
Background technique
Iron rust cannot such as be removed by loose, porous, (expanding) that continue to develop material composition and be attached to substrate
On iron rust, paint film will be unable to combine closely with metal surface, and paint layer is easy to fall off and corrosion-resistant effect is not achieved, therefore, one
As iron rust removed when metal surface applies anticorrosive paint, this illustrates that the surface of steel is just handled for anticorrosive paint
It is vital.But in steel knots such as some heavy constructions, bridge, the inside of large-scale precision equipment, inflammable and explosive gas-holders
In the preservation process of structure, limited by factors such as steric requirements, anticorrosive construction personnel safeties, it have to by hand or electric tool
It derusts and derusting by sandblasting technology cannot be used, not only large labor intensity, production efficiency are low in this way, and operating expenses is high, and rust dirt is serious
It is detrimental to health, the effect of derusting by sandblasting is not achieved in derusting effect.Therefore, it is intended that develops a kind of function admirable can
It can guarantee the coating of preferable derusting effect when being sprayed on certain rusty surface.
Summary of the invention
For the problems in the relevant technologies, the present invention has studied a kind of on rust paint, with provide it is a kind of can be quickly and efficiently
Convert the on rust paint of iron rust and durable.
The present invention provides a kind of on rust paints, as mass fraction, comprising: 10%-40% modified epoxy,
8%-15% alkyd resin, 5%-12% phytic acid, 5%-10% phosphoric acid, 10%-30% trbasic zinc phosphate, 5%-10% diatomite,
5%-10% micaceous iron oxide gray, 1%-2% dispersing agent, 1%-3% drier, 3%-8% ethyl alcohol and 3%-8% isopropanol.
In above-mentioned on rust paint, as mass fraction, coating includes the modified epoxy of 25%-35%.
In above-mentioned on rust paint, as mass fraction, coating includes the alkyd resin of 10%-12%.
In above-mentioned on rust paint, as mass fraction, coating includes the phytic acid of 7%-9%.
In above-mentioned on rust paint, as mass fraction, coating includes the phosphoric acid of 6%-8%.
In above-mentioned on rust paint, as mass fraction, coating includes the trbasic zinc phosphate of 15%-25%.
In above-mentioned on rust paint, as mass fraction, coating includes the diatomite of 6%-8%.
In above-mentioned on rust paint, as mass fraction, coating includes the micaceous iron oxide gray of 6%-8%.
In above-mentioned on rust paint, as mass fraction, coating includes the dispersing agent of 1%-1.5%.
In above-mentioned on rust paint, as mass fraction, coating includes the drier of 1.5%-2.5%
In above-mentioned on rust paint, as mass fraction, coating includes the ethyl alcohol of 5%-6%.
In above-mentioned on rust paint, as mass fraction, coating includes the isopropanol of 4%-6%.
In above-mentioned on rust paint, modified epoxy be phenolic hydroxyl group polyimide epoxy, bisphenol-A epoxy resin,
One of bisphenol f type epoxy resin or a variety of combinations.
In above-mentioned on rust paint, dispersing agent be polycarboxylate, polyacrylic acid derivative, the liquor-saturated copolymer of maleic acid,
One or more combinations of Plasmosan, polyethylene glycol.
In above-mentioned on rust paint, drier is polyamide curing agent, ring grease amine curing agent, polyisocyanates
One or more combinations of class curing agent, cobalt naphthenate curing agent.
The present invention provides a kind of on rust paints, by being matched using hydroxyl abundant in modified epoxy with iron ion
Position to promote the conversion of corrosion, then improves by the way that various fillers are added the seepage velocity, resistance to of prepared on rust paint
Extent of corrosion, physical shielding effect, curing rate etc., so that prepared on rust paint energy can not only be quickly and efficiently
Iron rust is converted, but also there is good physical shielding effect, durable.Prepared on rust paint can be applied to rotten
In the secondary corrosion protection system of arbor part, it is applied in corrosion cell, so that the surface of corrosion is formed finer and close macromolecule and apply
Material slows down corrosive medium and penetrates coating and metal material contact, and coating has cut off the access of corrosion cell, even if corrosion potential
Difference still remains, but corrosion cell at this moment is in off state, cannot form corrosion current.In addition, such as hydroxyl in coating
Base isoreactivity group can occur chemical reaction with metallic element and form passivating film in metal surface, change metal surface
Structure and metal component, make corrosion cell generate electrode polarization, change former corrosion cell, reduce corrosion rate.
Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described reality
Applying example is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field
