Description

A kind of preparation method of nanometer of enhancing water-based anticorrosive paint
Technical field
The present invention relates to the preparation method of a kind of nanometer of enhancing water-based anticorrosive paint, 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 workshop, 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 Metal erosion problem, can be protected using multiple technologies, slowed down or prevented corrosion of metal, wherein most effective, most common 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, influences human body health.Nowadays, environmental protection is paid more and more attention, pollution-free, nuisanceless, and save the energy becomes 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, becomes the mainstream of future development, but water-based anticorrosive paint performance still lags behind oil paint at present.
With the continuous progress of material technology, the excellent specific property of nano composite dope increasingly attracts people's attention.Nanometer material Material has the characteristics such as small-size effect, skin effect, quantum effect, and nano material is dispersed in traditional anticorrosive paint, can be carried High coating property.Sun Jinyu etc. is by Nano-meter SiO_22Particle is added in water-based epoxy resin, and it is compound to prepare aqueous epoxy nano Coating, the results showed that coating has preferable antiseptic property.Xue Li etc. is nano-TiO2Particle is added to epoxy resin and solvent In, improve coating mechanical property and corrosion resistance.It is organic anti-that patent CN2013 10672858.8 discloses a kind of titanium nanometer The preparation method of rotten coating, it adds titanium nano particle in epoxide modified aqueous polyurethane emulsion, and the anti-corrosion prepared applies Material is with preferable stability, water resistance and corrosion resistance.Patent CN201510104241.5 discloses a kind of organosilicon anti-corrosion and applies Material and preparation method thereof, it is toward with the addition of Nano-meter SiO_2 in coating2Powder and nano-ZnO, the product prepared is not only corrosion-resistant, It is wear-resistant, and the impervious power of waterproof layer cracking resistance formed is strong, good water-proof effect, service life length.Patent CN20171015 2282.0 disclose nano rare earth modified epoxy anticorrosive paint and preparation method thereof, which has good uvioresistant And against weather.
At present, although nanometer enhancing anticorrosive paint makes some progress, more problem is still suffered from.Since nanometer is filled out Expect that specific surface area is big, surface free energy is high, and nano-particle is easily reunited, and makes nanoparticle even with the methods of ball milling, high-speed stirred Son is dispersed in coating, but they can also reunite, and loses the due effect of Nano filling.In addition, though inorganic nano is filled out The addition of material can strengthen coating mechanical property, but the combination between inorganic filler and organic matrix is weaker, cause coating to oxygen The iris action of gas and water etc. weakens, anti-corrosion bad stability.In short, the research and development of current nanometer enhancing anticorrosive paint still have Treat in new breakthrough.

From comparative example 1 as can be seen that working as SiO2Colloidal sol is individually added with conventional inorganic filler, coating pencil hardness, resistance to punching Hitting property and salt spray resistance have decline.The present invention is in advance by nanometer sand mill to SiO for this explanation2Colloidal sol and general inorganic are filled out Expect co-ground, formed and receive the rock-steady structure unit of micro- cladding, to avoiding nano particle deuterogenesis from reuniting, strengthen coating mechanics Performance and antiseptic property effect are obvious.
From comparative example 2~3 as can be seen that adjustment resin emulsion and filler usage of sizing agent are obvious on coating performance influence, when Reduce resin emulsion dosage, increase filler usage of sizing agent when, resin to filler coat it is insufficient so that cause coating adhesion, Salt spray resistance declines obvious.And when increase resin emulsion dosage, reduce filler slurry used time, coating pencil hardness and impact resistance The mechanical properties such as property decline substantially again.
Unused nano material in comparative example 4, no nanometer enhancement effect, therefore, coating mechanical property and salt spray resistance Equal degradation.Nano material dosage is excessive in comparative example 5, and coating shrinkage can be caused serious, and coating becomes fragile, cracks, and performance is very Difference.Nano material dosage is reduced in comparative example 6, nanometer humidification weakens, and coating mechanical property and salt spray resistance are homogeneous Determine degree to decline.
Filler slurry maximum particle diameter increases to 5 μm in comparative example 7, can reduce between organic resin and inorganic filler and be tightly combined Degree, therefore coating mechanical property and salt spray resistance are declined slightly.Comparative example 8~11 is to change nanometer sand mill technique ginseng Number, it is exactly that slurry maximum particle diameter increases to directly affect, and therefore, properties of coating declines.Comparative example 12 is reduced Coating mixing time, can influence coating uniformity, therefore coating performance is also declined slightly.
