Talcum powder 3-6 part;
Barium sulfate 2-4 part;
Anti-settling auxiliary agent 3-5 part;
Dispersing auxiliary 1-2 part;
Solvent 10-13 part;
By ratio of quality and the number of copies, second component comprises following component and content:
Solidifying agent 50-60 part;
Solvent 40-50 part.
Described epoxy resin is E44 epoxy resin.
Described nanometer aluminium powder particle diameter is 100 nanometers.
Described anti-settling auxiliary agent is organobentonite powder.
Described dispersing auxiliary is soybean lecithin.
Use same solvent in described first and second components, in the first and second components, described solvent is dimethylbenzene and propyl carbinol is formulated according to volume ratio 5:1.
Described solidifying agent is modified by cardanol polyamide resin.
The preparation in accordance with the following methods of the rich aluminium nano paint of ocean heavy antisepsis epoxy, step comprises:
(1) by formula ratio, epoxy resin and Hydroxylated acrylic resin are added in agitator, under the stirring of the speed of 300r/min, add solvent, talcum powder, barium sulfate, anti-settling auxiliary agent, dispersing auxiliary in order successively, slowly nanometer aluminium powder is added under stirring with the speed of 1500r/min again, churning time is 30 minutes, obtains first component;
(2) to be added by solidifying agent modified by cardanol polyamide resin by formula ratio and get the raw materials ready in pot, under the stirring of the speed of 1000r/min, add solvent, high speed dispersion 10 minutes, obtains second component;
(3) need be 18:1 by formula ratio quality proportioning by described first component, second component during construction, mixing, uniform stirring, leaves standstill and can use after 10 minutes.
In the present invention, epoxy resin and Hydroxylated acrylic resin are as the main film forming substance of the rich aluminium nano paint of epoxy, utilize two kinds of resin synergies, can play and no matter well sealing process is completely cut off to steel substrate, stop and isolation corrosive medium, improve steel substrate resistance to corrosion, epoxy resin and Hydroxylated acrylic resin can block cathodic reaction as main film forming substance in the coating of steel substrate surface formation, improve paint coatings corrosion resistant effect.
Nanometer aluminium powder adds as antirust bulk 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 play sacrificial anode effect; because along with the continuous flowing of electric current; anode material constantly consumes. and aluminium powder, as sacrificial anode material, effectively can exempt from galvanic corrosion by electrochemical action protection steel substrate.Aluminium powder is compared zinc powder in addition, although all play sacrificial protection effect, in equal quality situation, aluminium powder volume is larger, and that is relative cost can be lower.Aluminium powder in the coating formed is nano material, has small-size effect and surface effects, can form fine and close paint film, effectively can intercept the erosion to steel surface such as air from physical action simultaneously.
Talcum powder and barium sulfate add as paint filler, and both collaborative adds the thickness that effectively can improve coating and once spray, and effectively improves the injury resistant ability of coatingsurface, effectively reduce overall coating cost.
The Main Function that adds of organobentonite powder prevents these primary solids composition sedimentations in coating of metal powder, talcum powder and barium sulfate, can improve stability and the consistency of metal powder, talcum powder and barium sulfate.
Adding of soybean lecithin makes metal powder, talcum powder and barium sulfate molecule more easily disperse and stir, soybean lecithin can improve the hydrophile-lipophile balance value of metal powder, talcum powder and barium sulfate, there is solidifying wadding in effective control, and effectively improve aluminium powder, talcum powder and barium sulfate and form the opacifying power after coating, and stability in coating slurries and viscosity.
Modified by cardanol polyamide resin finally adds as solidifying agent, in main this coating of consideration, main film forming substance is epoxy resin and Hydroxylated acrylic resin, modified by cardanol polyamide resin surface energy is low, good to substrate wettability, its add as solidifying agent after coating and the steel substrate sticking power excellence that formed of coating.
Above all substances mix together coating with mass ratio in order, wherein there is synergistic effect in each substance to greatest extent, steel substrate formed coating there is stronger anticorrosion ability.
Case effect, carries out the resistance to neutral salt spray time of neutral salt spray test according to ISO 9227-2006 salt-fog test standard
| Example | Example 1 | Example 2 | Example 3 | Example 4 |
| The resistance to neutral salt spray time | 1023 hours | 1035 hours | 1043 hours | 1012 hours |
The invention has the beneficial effects as follows:
In the present invention, the usage percentage of each raw material is that contriver draws on lot of experiments basis, in above-mentioned amount ranges, have good effect.
The present invention; metal powder is high efficiency dispersion in the coating; effectively can fill the pin hole of coating; the formation of the various defects in remarkable minimizing coating; nanometer aluminium powder content is wherein high; in atmospheric marine environment, effectively serve the electro-chemical protection on surface, be specially adapted to extreme high humidity, high hot atmospheric marine environment steel structure surface is anticorrosion.
Adopt the present invention, the nanometer aluminium powder content in paint film is high, with low cost, and technique is simple, without the need to specific installation.The present invention by coating prepared by the present invention and basal body binding force strong, also there is good bonding force corrosion resistant performance in atmospheric marine environment outstanding with other various additional coatings simultaneously, long service life, can be applicable to the heavy-duty coating of the iron and steel structures such as the drilling unit of atmospheric marine environment, bridge.
In addition because the density of aluminium is far below the density of zinc, the zinc-rich paint consumption of aluminium powder consumption relatively with traditional is low, and cost significantly reduces, thus reaches the object significantly improving epoxy aluminum-rich coatings over-all properties.Solve Present Domestic in various marine settings engineering marine corrosion problem in the urgent need to, in oil drilling platform and South China Sea islands, have important application prospect in the equipment such as steel structure surface protection and engineering.
Paint of the present invention is adopted to form 100 μm of thick coatings, through the accelerated corrosion analog reslt Neutral Salt Spray Corrosion life-span: be greater than 1000 hours.
