Description
Technical field
The present invention relates to a kind of anticorrosive coating, particularly a kind of heat reflection type epoxy anticorrosion coating.
Background technology
The metallic corrosion economic loss such as the annual invar iron in the whole world reach 1,000,000,000,000 dollars, account for the 2-4% of various countries' gross national product, are 6 times of the loss summations such as earthquake, fire and typhoon, and the annual loss therefore of China is 1.19 trillion Renminbi.
Tackling the corrosion optimum method is to adopt anticorrosive coating, wherein especially can stand the heavy duty system of time check as main under harsh corrosive environment.
Using one of the most active field at current heavy-duty coating is petroleum chemical industry, particularly deposit large-scale storage tank and the storage tank of petrochemical complex product in the open under the environment, it is exposed to the sun and rain constantly, for preventing that these inflammable position fire and these chemical are because of successively rotten damage of being heated, so need to coat at these positions heat insulating reflecting coating, anticorrosive coating also is necessary certainly.
Conventional heat reflection coatings all is to be combined to make a protection system with anti-corrosion primer; what generally use in petrochemical industry at present is solvent type heat reflection coatings; need the multiple tracks application just can reach the thickness of 250-500 μ m; generally need 5-7 application; each overlay painting interval time is between 8-24 hour; no doubt can play good protection effect so coat two kinds of dissimilar coating; but because the operation of construction is more; not only waste material but also do not save time, the solvent of volatilization impacts environment again simultaneously.
Therefore, need especially a kind of heat reflection type epoxy anticorrosion coating, to solve the above-mentioned existing problem that exists.
Summary of the invention
The object of the present invention is to provide a kind of heat reflection type epoxy anticorrosion coating, for the deficiencies in the prior art, with thermal-arrest reflection and corrosion proof function in one, only need application 2 times, just can reach 300-400 μ m, can not only save time by material-saving, also plug a gap for domestic paint field simultaneously, it is long not contain simultaneously organic solvent and protection life-span, could satisfy heat insulating reflecting and the etch-proof problem of open-air storage tank basin to solve two kinds of various types of coatings of present needs.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of heat reflection type epoxy anticorrosion coating, it is characterized in that, it comprises the component of following weight percent: bisphenol A type epoxy resin (E51) 25-35%, reactive thinner 10-15%, titanium dioxide 5-10%, hollow glass micropearl 5-10%, ir radiation powder 3-5%, barium sulfate filler 10-24%, auxiliary rheological agents 0.3-1.0%, dispersion agent 0.2-0.5% and solidifying agent 15-25%.
In one embodiment of the invention, described auxiliary rheological agents is one or several combination in hydrogenated castor oil, organobentonite or the aerosil.
In one embodiment of the invention, described dispersion agent is food level soybean Yelkin TTS.
In one embodiment of the invention, described reactive thinner is cardanol glycidyl ether.
In one embodiment of the invention, described solidifying agent is Cardanol Modified PF Resin.
In one embodiment of the invention, described hollow glass micropearl is the S38 of 3M company.
Heat reflection type epoxy anticorrosion coating of the present invention has following advantage:
1, no-solvent type system;
2, multi-functional system, can protection against corrosion again can heat reflection;
3, safety;
4, long life anti corrosion (＞15 years);
5, can adopt the airless spraying construction.
Heat reflection type epoxy anticorrosion coating of the present invention, compared with prior art, adopt no-solvent type heavy duty system system, can improve environment on the one hand, can economize on resources simultaneously, reduce cost, improve economic benefits, its guard time is long on the other hand, can reach more than 15 years, and being is worth obtaining approach; Can protection against corrosion, again can heat insulating reflecting, be applicable to iron and steel table and protection, especially can be used for open-air metal tank and storage tank surface, realize purpose of the present invention.
Characteristics of the present invention can be consulted the detailed description of following better embodiment and be obtained to be well understood to.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below further set forth the present invention.
Heat reflection type epoxy anticorrosion coating of the present invention, it comprises the component of following weight percent: bisphenol A type epoxy resin (E51) 25-35%, reactive thinner 10-15%, titanium dioxide 5-10%, hollow glass micropearl 5-10%, ir radiation powder 3-5%, barium sulfate filler 10-24%, auxiliary rheological agents 0.3-1.0%, dispersion agent 0.2-0.5% and solidifying agent 15-25%.
In the present invention, described auxiliary rheological agents is one or several combination in hydrogenated castor oil, organobentonite or the aerosil; Described dispersion agent is food level soybean Yelkin TTS.
In the present invention, described reactive thinner is cardanol glycidyl ether; Described solidifying agent is Cardanol Modified PF Resin; Described hollow glass micropearl is the S38 of 3M company.
Solidifying agent adopts the modified by cardanol phenolic aldehyde amine, energy fast setting, low-temperature curing, low toxicity; This solidifying agent can be fine compatible with bisphenol A type epoxy resin (E51), can be used for the metallic surface of low prepared surface, even also can be used for being with the temperature surface.The solidifying agent cross-linking density is high, and its anti-solvent, chemical-resistant, dimensional stability and thermotolerance are all very high, and the bottom materials such as iron and steel are puted forth effort height.
Reactive thinner is cardanol glycidyl ether, the toughner of epoxy resin high-performance, it is again good property thinner, to Resins, epoxy, solidifying agent structure similar composition is arranged, the performance that mixes is good, can identify oneself with in film process in the film forming composition, like this can be without organic solvent, and can improve largely again shock-resistant, compression, cracking resistance and the physical and chemical performances such as cohesive strength and chemical-resistant of paint film, and can reduce again the viscosity of coating system simultaneously, be conducive to coating application.
Hollow glass micropearl had both had mirrored effect, and the thermal and insulating performance of hollow is arranged again, was the key material of reflection solar heat, and it can also improve the functions such as levelling property, stain resistance and weathering resistance of coating.
The ir radiation powder is a kind ofly the sun power that absorbs can be transmitted into the material that airspace goes with the form of long wave, and this is with SiO
2, Al
2O
3Be base-material, with Fe
2O
3, CuO, MnO etc. are additive, through high temperature sintering, the ceramics powder that barreling becomes after pulverizing is because the effect of these two kinds of materials can improve reflectivity and emittance to solar heat greatly.
Titanium dioxide is rutile-type, is that specific refractory power is the highest in the present known white pigment, and refractive index the highest and particle diameter and the ideal white pigment that distributes thereof are that quite high heat reflectivity is arranged.
Therefore, because these components participate in prescription of the present invention, so make heat reflection type epoxy anticorrosion coating of the present invention have heat reflection and protection against corrosion dual-use function.
Use heat reflection type epoxy anticorrosion coating of the present invention; not only most of solar heat energy can be reflected back; greatly reduce the temperature on coated article surface; and can also protect by surfaces such as being coated with iron and steel and be not subjected to corrodibility high; so can be used for petrochemical complex container (basin, storage tank etc.), reactor, freight container, boats and ships; bridge, etc. the aspect.
