Abstract
A kind of epoxy selfreparing on rust paint and preparation method thereof, this epoxy selfreparing on rust paint is made up of epoxy resin, solid phosphoric acid compositions, auxiliary agent, solvent and firming agent etc..Its preparation method: utilize coupling agent to carry out solid phosphoric acid compositions peplos and process, then prepared epoxy selfreparing on rust paint by peplos solid phosphoric acid compositions.This coating has the strongest rusty scale conversion capability, can be widely applied to be difficult to the Anticorrosion Construction at the steel construction position of fully erased rusty scale.
Description
Technical field
The present invention relates to the preparation method of a kind of epoxy selfreparing on rust paint, belong to technical field of coatings.
Background technology
Existing on rust paint is many containing chromate or chromic acid coordination compound, generates miscellaneous many during these compound hydrolysis
Acid, heteropoly acid and rust react the complex generating stable suppression rust growth.As CN101698776A discloses a kind of oil well
Effective on rust paint, this coating raw material composition include alkyd resin, levelling agent, defoamer, dispersant, thickening agent, drier,
Anti-skinning agent, adhesion promoter, ferric oxide red powder, white carbon black, zinc phosphate, calcium carbonate, antirust agent powder and solvent.Antirust agent powder
End is chromic acid diphenylguanidine.Due to the restriction of environmental regulation, will prohibit the use of containing chromic coating.
Research worker steps up to study the on rust paint of environment-friendly type.The waterborne rusted paint of transformant is often used
To phosphoric acid.Phosphoric acid can react the iron phosphate generating resistance erosion with rust, also can generate phosphating coat at steel surface.CN1075176 is public
Having opened a kind of band rust steel surface treatment fluid, the chemical composition contained (weight %) is: water 40～70%, phosphatase 11 5～60%,
Also having a small amount of potassium nitrate, zinc oxide, potassium dichromate, organic acid etc., it is excellent that the steel surface being processed can form one layer of corrosion resistance
Different protecting film.If but a lot of problem then can be brought, if the moisture in phosphoric acid is with molten phosphoric acid in solvent based coating
The consistency problem of dosage form coating film forming matter, maximum problem is that coating is easily bubbled, and causes coating premature failure.
In order to phosphoric acid in solvent based coating, the present invention utilizes solid phosphoric acid compositions to prepare on rust paint,
Owing to solid phosphoric acid compositions is without free water, solve ask incompatible with solvent based coating film forming matter of phosphoric acid compositions
Topic.It addition, solid phosphoric acid compositions is carried out peplos process, solve solid phosphoric acid and cause coating foaming owing to dissolubility is big
A difficult problem.
Adding the solid phosphoric acid compositions after peplos in epoxy coating, prepared solid phosphoric acid/epoxy selfreparing band rust is coated with
Layer hinders the infiltration of corrosive medium so that coating has extraordinary Corrosion Protection.
Summary of the invention
The present invention is directed to phosphoric acid and there is consistency problem, and the problem that coating easily lost efficacy with solvent based coating, propose one
Plant epoxy selfreparing on rust paint and preparation method thereof, it is therefore an objective to a kind of durable coating of preparation, for corrosion metals matrix table
The application over rust in face.
Realization the technical scheme is that, epoxy selfreparing on rust paint of the present invention is made up of following two components:
Component one includes following components and content (in parts by mass):
Epoxy resin 50～80；
Auxiliary agent 0.5～5；
Solid phosphoric acid compositions 0.5～12；
Pigment 1～20；
Solvent 20～50；
Component two includes following components and content (in parts by mass):
Solvent 0～75；
Firming agent 25～100；
Component one is (100:1)～(100:80) with the proportioning of component two；
Described solid phosphoric acid compositions is the mixture of Metaphosphoric acid and dihydric phosphate.Metaphosphoric acid and dihydric phosphate matter
Amount ratio is (10:1)～(10:60).Dihydric phosphate such as aluminium dihydrogen phosphate, zinc dihydrogen phosphate, phosphate dihydrogen manganese, biphosphate
Barium, ammonium dihydrogen phosphate etc..
Described solid phosphoric acid compositions is the solid phosphoric acid compositions that coupling agent peplos processes.Described coupling agent is silicon
Alkane coupling agent.Silane coupler include vinyl-based, chlorocarbon class, ammonia alkyl class, epoxyhydrocarbyl, methacryloxypropyl alkyls,
Sulfur-bearing alkyl class etc., trade names such as WD-26, A150, WD-50, KH550, WD-60, KH560, WD70, KH570 etc..
Epoxy resin is one of bisphenol A type epoxy resin, bisphenol f type epoxy resin or their mixture.Concrete model
Such as E51, E44, E42, E20, F-51, F-46, F-44 etc..
Firming agent can be polyamide resin grease agent, ring grease amine curing agent, Mannich base class firming agent or theirs is mixed
Compound, presently commercially available firming agent such as 8115,650,651,203,600, T31 etc..
Pigment refers to titanium dioxide, iron oxide yellow, cadmium yellow, cadmium red, molybdate red, barba hispanica etc..
Solvent refers to prepare solvent conventional in epoxy coating, such as dimethylbenzene, toluene, n-butyl alcohol etc..
Described auxiliary agent is dispersant that coating is conventional, defoamer, levelling agent, anti-settling agent.Dispersant such as BYK company
Anti-Terra®-U、Disperbyk®-115、Disperbyk®-140、Disperbyk®-160、Disperbyk®-163.Disappear
BYK-019, BYK-021, BYK-022, BYK-023, BYK-024, BYK-025, BYK-028 of infusion such as BYK company.Levelling agent

Toluene and 15kg titanium dioxide, stir 40 minutes；Again these epoxy resin compositions are ground, obtain epoxy selfreparing band rust
The component one of coating；Other reactor is dissolved in 50kg 8115 polyamide firming agent in 50kg toluene, makes
The component two of epoxy selfreparing on rust paint；In component one: the ratio of component two=100:70 joins component one component two
In, within ambient temperature curing 7 days, form epoxy selfreparing band rust coating.
Embodiment 3:
Under stirring, add 8.5kg above-mentioned peplos solid phosphoric acid compositions in a kettle., be then added to 64kg
E20 epoxy resin (solid content 75%), 0.5kg Disperbyk®-160 dispersants, 0.5kg JF-38 anti-settling agent, 11.5kg bis-

Salt spray test:
The present invention utilizes salt spray test to evaluate the Corrosion Protection of coating.Salt spray test is according to standard GB/T/T
1771-2007 is carried out, and uses continuous spray pattern.Solution is 5%NaCl (mass percent) solution, and test temperature is 35
±2℃.Utilize aerial spraying method that spray painting is removed floating 150mm × 75 mm become rusty after being exposed to the sun out of doors 6 months
On the Q235 steel plate of × 3 mm, normal temperature drying carries out edge sealing after 7 days, then carry out 200 hours salt spray tests.Coating dry film is thick
Degree is 150 ± 10 μm.
Table 1 is coating salt spray test result, and coating foaming situation shows to add peplos solid phosphoric acid of the present invention in the coating
Compositions has more preferable barrier propterty than adding the solid phosphoric acid compositions not having peplos to process.
