Description
Technical field
The present invention provides a kind of aqueous double-component epoxy paint for priming paint and top lacquer and preparation method thereof, belong to coating technology neck
Domain.
Background technique
With the increasingly attention and the continuous enhancing of people's environmental consciousness of Environmental protection work, water paint
Important directions and research emphasis as paint development.Epoxy resin is various in style, and spy is widely used in coating to haveing excellent performance
In production.Waterborne epoxy coatings has many advantages, such as solvent epoxy coatings: having splendid adhesive force, solidification to wide variety of substrates
Film corrosion resistance and chemical resistance afterwards be excellent, film shrinks that small, hardness is high, wear-resisting model, electrical insulation properties are excellent；Also
It is lower with organic solvent or VOC content, it not will cause air pollution, meet environmental protection requirement；Simultaneously using water as dispersion
Medium, cheap, odorlessness, transport and using safer at non-ignitable, storage；Construction tool can be washed with water；Water-base epoxy applies
The advantage of material, which is also manifested by the mixed system, to be solidified in room temperature and moist environment, and degree affected by environment is smaller, has
Reasonable curing time, and guarantee there is very high crosslink density, outclass common water soluble acrylic acid and aqueous polyurethane coating.
But current aqueous double-component epoxy coating is in order to meet workability, it is necessary to part cosolvent is added, to mention
The workability of high coating, so aqueous double-component epoxy coating more or less has some unpleasant temperature.
Chinese patent " a kind of aqueous acrylic modified two-component epoxy paint for priming paint and top lacquer of CN2017101339202 " provides
A kind of aqueous acrylic modified two-component epoxy paint for priming paint and top lacquer and preparation method thereof, using acrylic acid and epoxy in the patent
Crosslinking technology is introduced into acrylic ester monomer in epoxy resin, has both anti-corrosive properties and weatherability, is suitable for single coating bottom surface
Unification anti-decaying paint, bottom surface unify excellent combination property, solve the problems, such as that single coating sealing wax cannot be considered in terms of anti-corrosive properties and weatherability.
However a small amount of environmentally friendly solvent is still added in the patent, and although it is extremely low to be known as VOC content in the patent, < 50g/L,
Still there is biggish gap apart from the target of Diamond Search.Therefore the Diamond Search coating of lower smell is always vast coating user
Thirst for.
Summary of the invention
The present invention provides a kind of aqueous double-component epoxy paint for priming paint and top lacquer, solve the deficiency in background technique, this is specially
Any cosolvent is not used in benefit, it can reach splendid film-formation result and paint film property, it is most important that its VOC content <
2g/L has substantially carried out Diamond Search.
Realize technical solution used by above-mentioned purpose of the present invention are as follows:
A kind of aqueous double-component epoxy paint for priming paint and top lacquer, is grouped as by first component and second group, and the first component includes following
The mass parts of substance, each substance and each substance are respectively as follows:
The second component includes following substance, and the mass parts of each substance and each substance are respectively as follows:
Amine epoxy curing agent modified 45-55
Aliphatic alcohol polyoxyvinethene phosphate/salt 0.1~0.5
Deionized water 49.5~49.9
The first component and second component are mixed according to the mass ratio of 6~10:1, to obtain aqueous double-component epoxy bottom surface
Unification paint.
The dispersing agent is excellent card chemistry UNIQ SPERSE 690W.
The wetting agent is Digao Twin 4100.
The thickener is aqueous liquid polyamide auxiliary rheological agents BYK-440.
The defoaming agent is Digao TEGO-810 defoaming agent.
The anti-settling agent is this BENTONE LT of hamming.
The pigment includes one or more of iron oxide red, titanium dioxide and yellow pigment；The iron oxide red is domestic oxygen
Change iron oxide red, the titanium dioxide is domestic rutile type titanium white, and the yellow pigment is No. 74 Huangs of pigment.
The rust resisting pigment is polyphosphoric acids calcium aluminium.
The substrate wetting agents are Digao TEGO-270.
The anticorrosive is this FA-179 of hamming；The antimildew disinfectant is ROHM AND HAAS KATHON LXE.
Compared with prior art, technical solution provided by the invention has the advantage that has used zero first in the present invention
The epoxy emulsion and aliphatic alcohol polyoxyvinethene phosphate/salt of VOC, therefore demand of the coating to cosolvent is greatly reduced,
Splendid film-formation result and paint film property can be reached without using any cosolvent.Higher boiling environmentally friendly solvent has been eliminated completely
It uses, smell greatly reduces.And use aliphatic alcohol polyoxyvinethene phosphate/salt due to using phosphate as water-wet side
It is opposite to have higher anti-flash rusting grade and salt fog resistance with other common ionics and nonionic emulsifier, it is cast in sandblasting
Even if any anti-flash rusting auxiliary agent is not added on iron there will not be any flash rusting.Aliphatic alcohol polyoxyvinethene phosphate/salt can mention simultaneously
For one good thixotropic state of coating system, a good sprayability can be provided additionally not adding thickener and resisted
Flow.
