Description
Technical field
The present invention relates to a kind of coating, specifically a kind of methanol-resistant, static-conducting and anti-corrosive paint.
Background technology
Methyl alcohol is easy to produce static in loading and unloading, transportation, storage process, therefore, reservoir walls should be used the anti-electrostatic anticorrosive coating.The static conductive coating that uses in the prior art has common epoxies, polyurethanes, phenolic etc. because space structure is fine and close inadequately, through the evidence methanol molecules be easy to by, be in for a long time in the methyl alcohol environment, filming is easy to swelling, foaming, and finally comes off.On the other hand, the electrostatic conductive performance poor stability of static conductive coating in the prior art is along with the prolongation of time, electrostatic conductive performance descends, and can not in time leak static charge, in case build-up of static charges is to above the breaking down field strength of medium the time, will cause spark discharge, lead to fire explosion.
And the content of conductivity, whiteness and the depositing metal oxide of the employed static conductive filling material of preparation electrically conducting coating is closely related, therefore, when conducting powder content is low, conducting powder whiteness height, but the electrostatic conductive performance general homology descends.Therefore, the depth of electrostatic conductive performance and painting color is difficult to satisfactory to both parties.
Summary of the invention
Purpose of the present invention just provides the methanol-resistant, static-conducting and anti-corrosive paint of a kind of coating densification, the corrosion of anti-methyl alcohol and electrostatic conductive performance good stability.
Methanol-resistant, static-conducting and anti-corrosive paint of the present invention, form by weight by following raw material:
The A component
Resins, epoxy 18～33, static conductive filling material 18～35,
Pigment 1～30, filler 1～30,
Auxiliary agent 2～4, thinner 10～30;
The B component
Modification virtue fat amine curing agent 8～20.
Among the present invention, Resins, epoxy is made up of by weight 2～3: 5 ratio Resins, epoxy E44, Resins, epoxy E51; Solidifying agent is D8196 or D8190.Static conductive filling material is made up of by weight 5: 1～2 ratio conductive mica powder, conductive zinc oxide.
Pigment of the present invention, filler, auxiliary agent and thinner all can use by conventional materials and consumption in the prior art.Pigment can be selected one or more the mixing in titanium dioxide, ferric oxide (red, Huang), yellow ultramarine, zinc-chrome yellow or the zinc sulfide white for use.Filler is one or more the mixing in barium sulfate, zinc phosphate, zinc oxide, talcum powder, mica powder, magnesiumcarbonate, aluminium triphosphate or the lime carbonate.
Auxiliary agent of the present invention is one or more the mixing in anti-settling agent, wetting dispersing agent, flow agent or the defoamer.Wherein anti-settling agent is one or more mixing in polyethylene wax, polyamide wax, organobentonite or the potter's clay.Wetting dispersing agent is unsaturated carboxylic acid amine salt class, modified polyorganosiloxane class, one or more the mixing in polyamide-based.Flow agent is one or more mixing in polyether-modified polydimethylsiloxane class, the fluorine-carbon modified polyacrylic.Defoamer is one or more mixing in modified organic silicon oxygen alkane type, broken bubble polymkeric substance, the dimethyl silicone oil.
Thinner of the present invention is one or more the mixing in dimethylbenzene, propyl carbinol, isopropylcarbinol, the pimelinketone.
The Resins, epoxy that the present invention uses can with the used solidifying agent of the present invention in conjunction with forming fine and close spatial network, guarantee functional color stuffing is tightly coated, medium osmosis is not corroded.And the carbochain of Resins, epoxy E44 is longer, not only can give to film certain snappiness is provided, and with the used solidifying agent generation of the present invention curing reaction the time, can not occur owing to active group too much causes the too fast problem that makes some thinner also have little time to volatilize to be closed in the paint film of curing speed.The evaporable thinner does not cause paint film that the space is arranged in paint film, and is poor because of its density, makes that corrosive medium is easy to infiltrate, thereby causes the degradation of finished product protection against corrosion, anti-methyl alcohol.The present invention with Resins, epoxy E44 and E51 in 2～3: 5 ratio component epoxy mixture, thereby the paint film density that both can obtain obtains the good corrosive effect of anti-methyl alcohol, go back the may command curing speed simultaneously, make and extend to 6～8 hours set time, realize both improving the salient features of finished product thus simultaneously, helped the multipurpose of constructing operation again.
The modification virtue fat amine hardener that the present invention adopts, combination as aromatic amine and aliphatic amide, have fast, the colourless advantage of the speed of response of aliphatic amide and the advantage good of aromatic amine with the Resins, epoxy compatibility, especially introduce long hydrocarbon chain on the modification virtue fat amine curing agent molecule and therefore had good snappiness, because the phenolic hydroxyl group on the phenyl ring of modification virtue fat amine curing agent has katalysis, and the part amido is connected on the alkyl, so the curability at low temperatures of finished product is good.Because the part active primary amine base of this solidifying agent is closed, therefore using under higher levels of humidity does not still influence gloss and recoatability.
Static conductive filling material selects for use conductive mica powder and conductive zinc oxide with 5: 1～2 ratio composition mixture.The static conductive filling material that obtains according to the above ratio has the effect of synergy during use, make the electrostatic stabilization of leading of finished product be significantly improved; Simultaneously, because its synergistic function, both use together and can reduce the consumption of static conductive filling material under the prerequisite that obtains the identical conduction effect.Thus, under the certain situation of overall solid content, the reduction of static conductive filling material consumption can make all the other effective constituents such as anticorrosion raw material consumption suitably increase, thereby the antiseptic property of finished product is improved.The static conductive filling material mixture that the present invention uses is except that having excellent conductivity, and the stability of dispersiveness, whiteness and electrostatic conductive performance all is better than single static conductive coating.Dispersiveness makes the coating preparation process that operability preferably be arranged, and for the static conductive coating as the methyl alcohol reservoir walls, white or near-white are easy to find the defective of reservoir walls.Because the electrostatic conductive performance good stability of static conductive filling material used in the present invention makes coating of the present invention when being used for the methyl alcohol reservoir walls, exists under the situation in the METHANOL MEDIUM condition, the paint film electrostatic conductive performance descends seldom, and surface resistivity does not have to change substantially.
The present invention adopts above-mentioned specified raw material to make finished product by specified proportion, and not only preparation technology is simple, easy handling, and the various performances of made finished product all are better than existing procucts: finished product has good electrostatic conductiveness, and coating surface resistivity is 10
6～10
7Ω; Finished product excellent corrosion resistance, paint film have good acidproof, alkaline-resisting, anti-gasoline, anti-diesel oil, water-fast, salt water resistance corrosion; Standing storage methyl alcohol can not ooze out particle, and is pollution-free to methyl alcohol; The conductivity good stability, through the immersion of methyl alcohol, coating surface resistivity does not have considerable change.
