Description
Technical field
The invention belongs to paint field, and in particular to a kind of one-component salt spray resistance water paint and preparation method thereof.
Background technology
When metal is in moist air, due to the activity on its surface, there is absorption to make to the polarity moisture in air
With foring water membrane, when water film reaches certain thickness, be formed electrolyte solution necessary to electrochemical corrosion.
Either oxygen uptake corrosion or gas-evolving electrodes, because anode region is in contact with each other with cathodic region, electronics under the effect of Corrosion Electric Field power,
Just negative electrode is shifted to from anode, and is absorbed by the neighbouring medium being reduced, complete electrochemical corrosion.Again because in air
Under the conditions of, the depolarizing agent such as oxygen, moisture is relatively sufficient presence, so the continuous occurrence and development of metal erosion phenomenon.Adopt
It is most simple, economic, effective method that metal erosion is prevented with paint spraying.At present, limited by petroleum resources and environmental regulation
System, anticorrosive paint starts to be developed from traditional organic solvent type to the direction of " greenization ", and wherein Water-borne modification technology is to grind now
One of the emphasis studied carefully and main development direction.
The features such as aqueous anticorrosion paint has excellent gloss, durability, protects light colour retention, hardness and pliability on the market,
Particularly in field of Environment Protection, as new environment-friendly materials, the favor of consumer is increasingly subject to.However, due to water paint
Particularity, causes the function of current its salt spray resistance of aqueous rust-proof coatings to be not so good as oil paint, is also to hinder water-based anticorrosive paint
One big obstacle of promotion and application.
The content of the invention
It is an object of the invention to provide a kind of one-component salt spray resistance water paint and preparation method thereof, excellent product performance：

The remarkable advantage of the present invention is：Excellent product performance：Hardness >=H, 0 ~ 1 grade of adhesive force, salt spray resistance 800 hours；
Using newest interpenetrating networks synthetic technology, the Special environment protection resin of grafting synthetic technology synthesis, needed for being introduced on strand
Extraordinary top grade anti-corrosion molecular substance, obtain excellent anticorrosive property performance.Weakly alkaline pigment is used simultaneously, increases suitable face
Expect volumetric concentration, the quantity of fluoropolymer resin base-material in coating is wrapped up granules of pigments in coating, during film coalescence, reach
To emulsion particle with interacting spaced uniform three dimensional network state.
Compared with prior art, technique effect of the invention：（1）Traditional h of aqueous one-component anticorrosive paint salt spray resistance 100
The limit is just reached, salt spray resistance of the present invention was up to 800 hours, and can match in excellence or beauty traditional paint anticorrosive paint；（2）The present invention has
The features such as curing rate is fast, water-resistance is excellent, chemical resistance is good, anti-stain characteristic is good, can be widely applied to automobile, engineering machinery, instrument
The application in the fields such as device equipment.（3）It is of the invention mainly to use water as diluent, without volatile substances such as formaldehyde, meet European Union
VOC emission standard, produces influence smaller to environment and human body.（4）The drying time of coating is saved, cost is reduced, coating is reduced
Inflammability；（5）Diluent free and cleaning agent cost, while the overall energy consumption of room ventilation can be reduced；（6）Construction time limit pole
Long, performance is stable, and paint film appearance is good, is common to a variety of corrosion resistant occasions.
