Abstract
The invention provides waterborne epoxy quick-drying anti-corrosion coating and a preparation method thereof. The coating comprises a component A and a component B, wherein the component A comprises waterborne quick-drying epoxy resin, micaceous iron oxide red, hardness-increasing ceramic powder additives, waterborne zinc phosphate, nano natural barium sulfate, hydrocarbon resin, dispersing agent, defoaming agent, foam inhibitor, cosolvent, neutralizing agent, wetting agent, hydrated magnesium silicate, organic bentonite, fumed silica, flash rust preventing agent, waterproofing agent and distilled water; the component B is waterborne quick-drying epoxy curing agent. The preparation method includes blending the component A and the component B according to the ratio of 5:1. The waterborne epoxy quick-drying anti-corrosion coating and the preparation method thereof have the advantages that the hydrocarbon resin and the waterproofing agent are used to modify the waterborne quick-drying epoxy resin so as to prepare the anti-corrosion coating, and the paint film of the prepared coating is good in quick-drying performance, adhesive force, hardness, water resistance and salt spray resistance.
Description
Technical field
The invention belongs to technical field of coatings is and in particular to quick-drying anticorrosive paint of a kind of water-base epoxy and preparation method thereof.
Background technology
In industrial coating, anticorrosion coating material is a very important application.Epoxy resin is because it is excellent
Antiseptic property, the excellent adhesive attraction to iron and steel and concrete substrate and high cost performance, become the heaviest in anticorrosive paint
The coating variety wanted.On domestic market traditional solvent epoxy coatings still in the highest flight, the content of solvent can be high
Reach more than 60%-80%, discharge substantial amounts of solvent flashing pollutant in construction application in atmospheric environment.With social progress
Increasingly stricter laws and regulations requirement, developing high performance Environmentally friendly coatings becomes the important development direction of Coating Market.
For corrosion-resistant epoxy paint, powdery paints, high solids epoxy coating and aqueous epoxy coating are the masters of three development
Want direction.Because higher to the condition and equipment requirements of construction solidification, high solids epoxy coating and water-base epoxy apply powdery paints
Material has more superior workability, therefore more suitable for the construction application under room temperature situation.Epoxy coating is relatively early real
The coating variety of existing high solid, but the significant shortcoming of high-solid epoxy resin coating includes, and working life is short, slow drying speed, paint
Film pliability difference etc., during using quick-drying firming agent, cause again overcoating interval too short the drawbacks of, coating high cost also limit and pushes away
Wide application.For corrosion-resistant epoxy paint, another effective way reducing voc in coating is exactly to adopt Water-borne modification technology.But
It is that current aqueous epoxy coating is primarily present the shortcomings of antiseptic property is not enough, and drying condition is more harsh, storage period is shorter.
Content of the invention
The technical problem solving: the purpose of the present invention is to overcome the deficiencies in the prior art and provide a kind of water-base epoxy quick-drying
Anticorrosive paint and preparation method thereof, the paint film of gained coating has preferable quick-drying, adhesive force, hardness, resistance to water, salt spray resistance
Property.
Technical scheme: a kind of quick-drying anticorrosive paint of water-base epoxy, including a component and b component, wherein a component is with weight portion
Meter includes following raw material: aqueouss quick setting epoxy resin 28-36 part, mica iron oxide red 20-30 part, Hardening pottery flour additive agent 1-
3 parts, aqueous zinc phosphate 5-10 part, nanometer native sulfate of barium 10-15 part, hydrocarbon resin 0-4 part, dispersant 0.3-0.5 part, froth breaking
Agent 0.1-0.2 part, foam inhibitor 0.1-0.2 part, cosolvent 2-5 part, nertralizer 0.5-1 part, wetting agent 0.1-0.3 part, hydration silicon
Sour magnesium 0.3-0.5 part, organobentonite 0.3-0.5 part, aerosil 0.2-0.4 part, anti-flash rusting agent 0.5-1 part, waterproof
Agent 0-4 part, distilled water 8-15 part；B component is aqueouss quick setting epoxy firming agent.
Further, described cosolvent is propylene glycol propyl ether and the dipropylene glycol n-butyl ether mixing that 1:2 forms by volume
Thing.
Further, described a component also includes Microcrystalline Cellulose 0.01-0.05 part and/or polyvinyl alcohol 0.01-0.05
Part.
The preparation method of the quick-drying anticorrosive paint of above-mentioned water-base epoxy, be by a component and b component by 5:1 proportioning paint, a
The preparation method of component comprises the following steps:
Step 1, with distilled water as solvent, hydrated magnesium silicate is configured to the pre- slurrying a of 15wt%；
Step 2, with distilled water as solvent, organobentonite is configured to the pre- slurrying b of 8wt%；
Step 3, by aqueouss quick setting epoxy resin, distilled water, cosolvent, aqueous dispersion, nertralizer, aqueouss foam inhibitor,
Aqueous defoamer mixes, stirring, obtains mixture a；
Step 4, adds to aerosil, pre- slurrying a, pre- slurrying b in mixture a under agitation, dispersion, obtains
To mixture b；
Step 5, under agitation will be natural to mica iron oxide red, aqueous zinc phosphate, Hardening pottery flour additive agent, nanometer
Barium sulfate adds in mixture b, dispersion, is ground to fineness and is 50 microns, obtains mixture c；
Step 6, aqueous wetting agent, anti-flash rusting agent, waterproofing agent, hydrocarbon resin are added in mixture c, and stirring, in addition
Mediating recipe, obtains final product.
Further, in step 3, stirring condition is 300-400rpm, 5-10min.
Further, in step 4, mixing speed is 300-400rpm, and dispersion condition is 600-800rpm, 15-20min.

Performance test
Test method is: component a: component b=5:1 proportioning paint is diluted to spray using deionized-distilled water
Apply viscosity (30-45s, t-4 cup), standard tinplate sheet carries out phosphatization or grinding process, and in tinplate sheet, THICKNESS CONTROL is in 20-30
μm, do all-round property testing after 48 hours do solid work completely, salt spray resistance test dry plate THICKNESS CONTROL, at 80-100 μm, treats 7
It does salt spray resistance test after doing solid work completely.
Drying time according to gb/t1728, adhesive force according to gb/t5210, impact according to gb/t1732, toughness according to
Gb/t6742, hardness are according to gb/t6739, resistance to water foundation gb/t1733, freeze-thaw resistance according to gb/t9268, resistance to neutral salt spray
Property according to gb/t1771, using cn103087612a as comparison, result is as follows:
As seen from the above table, the present invention adopts aqueouss quick setting epoxy resin and aqueouss quick setting epoxy firming agent, obtained painting
Material paint film has preferable quick-drying, adhesive force, hardness, resistance to water, salt fog resistance.Entered by adding hydrocarbon resin or waterproofing agent
Row is modified, and the adhesive force of paint film, resistance to water, salt fog resistance, freeze-thaw resistance all have a distinct increment；It is simultaneously introduced hydrocarbon resin and prevent
After water preparation, paint film has more excellent quick-drying, and surface drying time is only 4min, and adhesive force rises to 18.5mpa, and impact reaches
60cm, hardness reaches 4h, and resistance to water reaches 720h, and salt spray resistance breaks through 2000h, and freeze-thaw resistance property rises to 20 times.Implement
Add Microcrystalline Cellulose in example 7, can further improve the adhesive force of paint film；Microcrystalline Cellulose and polyethylene is added in embodiment 8
Alcohol, also can significantly increase salt fog resistance, heat-resistant stability and the freeze-thaw resistance of paint film.
