Abstract
The present invention relates to anti-corrosion of metal field, it is desirable to provide a kind of water corrosion-resistant epoxy paint preparation method using trbasic zinc phosphate system Composite Anticorrosive Pigment Using.This method includes：Deionized water, cosolvent, auxiliary agent, rust resisting pigment, color stuffing are sequentially added into the material cylinder of dispersion machine, disperses 30~60min under 1000~2000rpm of rotating speed；The rotating speed of dispersion machine is reduced to 300~800rpm, aqueous epoxy resins is then added, continues 20~40min of stirring, obtain component A；B component epoxy hardener is added in component A when in use, water corrosion-resistant epoxy paint is obtained after stirring.The present invention can overcome in the prior art that solubility is low, water-disintegrable difference, and antirust activity is not high, effective delay, the defects of preventing " flash rusting " ability；Organic rust preventing pigment can be improved in inorganic rust resisting pigment area load efficiency by co-ground, chemiluminescence between the rust resisting pigments such as organic-inorganic, inorganic can be given full play of.Industrialized production is realized easily, suitable for harbour, Wharf Engineering machinery and the field such as ship, marine steel structure.
Description
Technical field
The present invention relates to a kind of water corrosion-resistant epoxy paint preparation method using trbasic zinc phosphate system Composite Anticorrosive Pigment Using, belong to
Anti-corrosion of metal field.
Background technology
Metal material is occupied an important position with its excellent mechanical performance and processing performance in Material Field, but metal is rotten
Erosion also causes huge loss to human society, storage equipment, petrochemical equipment, steel structure factory building, the ship manufactured such as metal material
Oceangoing ship, engineering machinery etc., due to being destroyed for a long time by chemistry or electrochemical action by loss, cause substantial amounts of economic loss.For
It metal erosion problem, can be protected using multiple technologies, slow down or prevent corrosion of metal, wherein most effective, the most frequently used
Method is to coat erosion shield in metal surface, is contacted with completely cutting off corrosive medium with metallic substrates, reaches corrosion-resistant purpose.When
Before, for anticorrosive metal paint mainly based on oil paint, coating process has substantial amounts of organic solvent to volatilize, and serious pollution is big
Gas, influence human body health.Nowadays, environmental protection is increasingly subject to pay attention to, pollution-free, nuisanceless, and save the energy turns into the present
The development principle of coating afterwards, and watery anti-corrosion paint is because its volatile matter is few, small to environment, human body harm, just gradually substitution passes
System oil paint, turn into the main flow of future development, but water-based anticorrosive paint performance still lags behind oil paint at present.
Water-based anticorrosive paint antiseptic property power depends on water-base resin and rust resisting pigment.And it is currently mainly used
Rust resisting pigment is trbasic zinc phosphate.Trbasic zinc phosphate is non-toxic, has no stimulation of the skin, the toxic heavy metal element such as not leaded, chromium, and heat is steady
It is qualitative good, wear-resisting, the decay resistance of coating can be significantly improved.But trbasic zinc phosphate is present, and solubility is low, water-disintegrable difference, antirust activity
It is not high, effective delay, it is oversize to form effective diaphragm time, it is impossible to be used in provisional protective coating and overcome " flash rusting " problem,
Zinc phosphate rust-preventive pigment development and application are caused to be greatly limited.To realize that zinc phosphate rust-preventive pigment substitutes conventional toxic comprehensively
The purpose of heavy metal rust resisting pigment, it is necessary to be modified to trbasic zinc phosphate, improve trbasic zinc phosphate system rust resisting pigment activity.
Currently, by trbasic zinc phosphate system rust resisting pigment grain diameter nano and by trbasic zinc phosphate system rust resisting pigment and organic rust preventing pigment
Compound (being referred to as " forth generation " trbasic zinc phosphate system rust resisting pigment) is two big research directions, as CN201210569946.0 discloses one
The preparation method of the efficient micro-nano preservative of trbasic zinc phosphate of kind, this method is using circulating ultrasonic cavitation effect and HTHP water-bath heat
The synchronous synergetic regulation and control of effect, the micro-nano preservative of efficient trbasic zinc phosphate is prepared, product purity is high, crystallinity is complete, particle diameter point
Cloth narrow range and good dispersion, effective anti-corrosion is for up to 1056h, far superior to commercially available trbasic zinc phosphate anti-corrosion material.F.Askari
et al(Synthesis and characterization of the fourth generation of zinc
phosphate pigment in the presence of benzotriazole,Dyes and Pigments,124
(2016), 18-26) potassium zinc phosphate/BTA (BTA) composite antirust filler, result of study be prepared for by coprecipitation
Show that BTA is combined together by physical absorption and N-Zn coordinations with potassium zinc phosphate, its antiseptic property better than trbasic zinc phosphate and
Potassium zinc phosphate.
Although although prior art achieves preferable effect in terms of by trbasic zinc phosphate system rust resisting pigment grain diameter nano,
Certain defect all be present in them.For example, some takes ultrasonic wave added in preparation process, some takes thtee-stage shiplock grinding
Reaction.First, caloric value is big when ultrasonic wave added method prepares nano material, and equipment requirement is high, is difficult to realize large-scale production, and super
After sound terminates, particle is easily reunited, particle size distributions wider range；Secondly, thtee-stage shiplock griding reaction method prepares nanometer phosphorus
Sour zinc, equipment is complicated, and investment is big, and reaction raw materials phosphoric acid is strong acid, and big to equipment corrosion, the trbasic zinc phosphate particle diameter of preparation is also led
Will be at hundreds of nanometers or so.In addition, trbasic zinc phosphate system/BTA Composite Anticorrosive Pigment Usings disclosed above are all by trbasic zinc phosphate system salt
The compound BTA of building-up process situ is prepared, but BAT can cause trbasic zinc phosphate system rust resisting pigment crystal defect, and prepare
Composite Anticorrosive Pigment Using particle diameter is still larger (10 μm or so), and the activity of trbasic zinc phosphate system salt is still relatively low.
