Summary of the invention
The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art, rich magnalium nano paint of the heavy anticorrosion epoxy in a kind of ocean and preparation method thereof is provided, this coating can significantly improve the resistance to corrosion of coating in atmospheric marine environment.
For achieving the above object, the present invention adopts following technical proposals:
The rich magnalium nano paint of the heavy anticorrosion epoxy in a kind of ocean, it is that 18:1 constitutes by the first and second two kinds of components according to the quality proportioning, according to the mass fraction, the first component comprises following component and content:
Resins, epoxy 14-18 part;
Hydroxylated acrylic resin 3-6 part;
Nanometer aluminium powder 100-115 part;
Nanometer Mg powder 25-30 part;

By ratio of quality and the number of copies, the second component comprises following component and content:
Solidifying agent 50-60 part;
Solvent 40-50 part.
Described Resins, epoxy is E44 Resins, epoxy.
Described nanometer aluminium powder particle diameter is 100 nanometers.
Described nanometer Mg powder particle diameter is 200 nanometers.
Described anti-heavy auxiliary agent is the organobentonite powder.
Described dispersing auxiliary is soybean lecithin.
Use with a kind of solvent in described first and second components, in first and second components, described solvent is dimethylbenzene and propyl carbinol is formulated according to volume ratio 5:1.
Described solidifying agent is the modified by cardanol polyamide resin.
The preparation in accordance with the following methods of the rich magnalium nano paint of the heavy anticorrosion epoxy in ocean, step comprises:
(1) pressing formula ratio adds Resins, epoxy and Hydroxylated acrylic resin in the agitator, under the stirring of the speed of 300r/min, add solvent, talcum powder, barium sulfate, anti-heavy auxiliary agent, dispersing auxiliary in order successively, speed with 1500r/min stirs down slowly adding nanometer aluminium powder and nanometer Mg powder again, churning time is 30 minutes, obtains the first component;
(2) by formula ratio solidifying agent modified by cardanol polyamide resin is added in the pot of getting the raw materials ready, under the stirring of the speed of 1000r/min, add solvent, high speed dispersion 10 minutes obtains the second component;
Needing described first component, second component when (3) constructing be 18:1 by formula ratio quality proportioning, mixes, and evenly stirs, and leaves standstill after 10 minutes and can use.
Among the present invention, Resins, epoxy and Hydroxylated acrylic resin are as the main film forming substance of the rich magnalium nano paint of epoxy, utilize two kinds of resin synergies, can play no matter steel substrate is well completely cut off sealing process, stop and isolate corrosive medium, improve the steel substrate resistance to corrosion, Resins, epoxy and Hydroxylated acrylic resin can be blocked cathodic reaction as main film forming substance in the coating that the steel substrate surface forms, improve paint coatings corrosion resistant effect.
Nanometer aluminium powder adds as antirust main body composition; because the current potential of aluminium is relative and steel substrate is more negative; the effect that we add nanometer aluminium powder is exactly to play the sacrificial anode effect; because along with constantly flowing of electric current; anode material constantly consumes. and aluminium powder can effectively exempt from galvanic corrosion by electrochemical action protection steel substrate as sacrificial anode material.The aluminium powder zinc powder of comparing in addition, though all play the sacrificial protection effect, the aluminium powder volume is bigger under the equal quality situation, that is to say that relative cost can be lower.Aluminium powder in the coating that forms is nano material, has small-size effect and surface effects, can form fine and close paint film, can be simultaneously effectively intercepts air etc. from the physical action to the erosion of steel surface.
Talcum powder and barium sulfate add as paint filler, and both collaborative addings can effectively improve the thickness that coating once sprays, and effectively improve the injury resistant ability of coatingsurface, effectively reduce whole coating cost.
It is to prevent these the main solids component sedimentations in coating of metal powder, talcum powder and barium sulfate that the adding of organobentonite powder mainly acts on, and can improve stability and the consistency of metal powder, talcum powder and barium sulfate.
The adding of soybean lecithin makes metal powder, talcum powder and the easier dispersion of barium sulfate molecule and stir, soybean lecithin can improve the hydrophile-lipophile balance value of metal powder, talcum powder and barium sulfate, effectively wadding appears coagulating in control, and effectively improve opacifying power after aluminium powder, talcum powder and barium sulfate form coating and the stability in the coating slurries and viscosity.
The modified by cardanol polyamide resin adds at last as solidifying agent, main film forming substance is Resins, epoxy and Hydroxylated acrylic resin in main this coating of consideration, modified by cardanol polyamide resin surface energy is low, good to the ground wettability, coating and steel substrate sticking power excellence that the coating after it adds as solidifying agent forms.
Above all substances mix together coating with mass ratio in order, wherein synergistic effect can take place in each material to greatest extent, the coating that forms at steel substrate has stronger anticorrosion ability.
Case effect, the anti-neutral salt spray time of carrying out the neutral salt spray test according to ISO 9227-2006 salt-fog test standard
| Example | Example 1 | Example 2 | Example 3 | Example 4 |
| The anti-neutral salt spray time | 1034 hours | 1052 hours | 1067 hours | 1031 hours |
The invention has the beneficial effects as follows:
The usage percentage of each raw material is that the contriver draws in a large amount of experimental basis among the present invention, has good effect in above-mentioned amount ranges.
The present invention; metal powder efficiently disperses in coating; can effectively fill the pin hole of coating; significantly reduce the formation of the various defectives in the coating; nanometer aluminium powder content height wherein; in atmospheric marine environment, effectively play surperficial electro-chemical protection effect, be specially adapted to the atmospheric marine environment steel construction surface anticorrosion of extreme high humidity, high heat.
Adopt the present invention, the nanometer aluminium powder content height in the paint film, with low cost, technology is simple, need not specific installation.The present invention is strong by coatings prepared of the present invention and basal body binding force, have also with other various additional coatings simultaneously that bonding force corrosion resistant performance in atmospheric marine environment is outstanding preferably, long service life can be applicable to the heavy-duty coating of the iron and steel structure such as drilling unit, bridge of atmospheric marine environment.
In addition since the density of aluminium far below the density of zinc, the aluminium powder consumption zinc-rich paint consumption with traditional relatively is low, cost significantly reduces, thereby reaches the purpose that significantly improves the rich aluminum paint over-all properties of epoxy.Solved current domestic in the New Equipment Engineering of various oceans the pressing for of marine corrosion problem, in oil drilling platform and island, the South Sea, in equipment such as steel construction surfacecti proteon and the engineering important application prospects is arranged.
Adopt coating of the present invention to apply to form 100 μ m thick coatings, through accelerated corrosion analog reslt neutral salt spray corrosion life: greater than 1000 hours.
