Description
The invention belongs to coating, oil-resisting antistatic and anticorrosive coating especially, oil-resisting antistatic and anticorrosive coating of the present invention is applicable to the occasion of metallic oil tank inner wall protection.Also can be applied to the occasion that computer house, operating table etc. need conductive coating.
Before the present invention made, the metallic oil tank inwall did not generally carry out coating protection, therefore used promptly to occur heavy corrosion about 10 years.Adopt Resins, epoxy or polyurethane coating commonly used at present to protect; though can prevent the corrosion of metallic oil tank inwall; but with the macromolecular material in this class coating is electrical insulator mostly; and oil product very easily produces buildup of static electricity in moving processes such as can; cause spark discharge and cause major accidents such as burning, blast, therefore must use electroconductibility antistatic coating.And the method that increases the coating static resistance mainly contains two kinds at present: the clear 56-159273 of a kind of JP of being, JP62-27472, the JP62-27474 patented technology, such coating is to add silver powder in insulativity filmogen such as Resins, epoxy or urethane resin, copper powder, zinc powder, nickel powder, carbon black, tin protoxide, the method of one or more conductors such as zinc oxide or semiconductor fills, to improve the oil-resisting antistatic antiseptic property of coating, but carbon removal infrablack price is all somewhat expensive in the added filler, cause the raising of coating cost, be not suitable for big area use in the oil tank, and metal wherein or metal oxide filler also influence the quality of oil product or the solidity to corrosion of coating, but use carbon black to do the requirement that filler can not satisfy the coating oil-resisting antistatic again fully separately; Another kind method is to select intrinsically conducting coating for use, be that polymkeric substance itself in the coating is exactly the material with electroconductibility, as polyphenylacetylene, poly-CuPc etc., but the cost of this class conduction high polymer is more expensive, and this technology still is in the scientific research stage, find no industrialness production, and its oil resistant corrosion resistance nature awaits to test, be difficult to realize.
Task of the present invention is the shortcoming that overcomes prior art, and a kind of metallic oil tank inner wall protection that is applicable to is provided, and has functional, low price, easy construction, safe and reliable oil-resisting antistatic and anticorrosive coating.
Oil-resisting antistatic and anticorrosive coating, include Resins, epoxy, carbon black or graphite, quiet dose of the anti-electricity of alkylamide, the toughner butylated melamine-formaldehvde resin, plasticizer phthalic acid diester class, mixed solvent (comprises acetone, propyl carbinol, dimethylbenzene), amine curing agent, the weight of each component is formed (in 100 parts of weight of Resins, epoxy): Resins, epoxy 100, carbon black or graphite 15-60, alkylamide static inhibitor 0.5-5, toughner butylated melamine-formaldehvde resin 5-20, plasticizer phthalic acid diester class 0-10, mixed solvent (acetone: propyl carbinol: 50-200 dimethylbenzene=1: 2: 12), amine curing agent 3-20, carbon black or graphite, its particle diameter are less than 83 microns, impure less than 1%, volume specific resistance is 1-10
-2Ohmcm.
Oil-resisting antistatic and anticorrosive coating, 50% xylene solution that includes hexanodioic acid-phthalic anhydride-glycerine-propylene glycol polyester, carbon black or graphite, the alkylamide static inhibitor, the toughner butylated melamine-formaldehvde resin, plasticizer phthalic acid diester class, mixed solvent (comprises ethyl acetate, pimelinketone, acetone), 60% xylene solution of Viscotrol C glycerin modification toluene diisocyanate prepolymer, the weight of each component is formed (with 50% xylene solution 100 of hexanodioic acid-phthalic anhydride-glycerine-propylene glycol polyester, carbon black or graphite 15-60, alkylamide static inhibitor 0.5-5, toughner butylated melamine-formaldehvde resin 5-20, plasticizer phthalic acid diester class 0-10, mixed solvent (ethyl hexanoate: pimelinketone: 50-200 acetone=3: 3: 4), 60% xylene solution 20-80 of Viscotrol C glycerin modification toluene diisocyanate prepolymer, carbon black and graphite, its particle diameter is less than 83 microns, and is impure less than 1%, volume specific resistance is 1-10
-2Ohmcm.
Method for producing coating of the present invention is to form by the weight of above-mentioned each component, in Resins, epoxy is filmogen (with 100 parts of weight), add carbon black or graphite 15-60 part therein, alkylamide static inhibitor 0.5-5 part, add toughner butylated melamine-formaldehvde resin 5-20 part again, plasticizer phthalic acid diester class 0-10 part, and mixed solvent (acetone: propyl carbinol: 50-200 part toluene=1: 2: 12), after sieving, grinding makes the A component, allocate B component amine cured article 3-20 part before use into, by the viscosity that mixing solutions is regulated coating, can use second by being coated with 4 glasss of 30-60.Perhaps 50% xylene solution in hexanodioic acid-phthalic anhydride-glycerine-propylene glycol polyester is filmogen (with 100 parts of weight), add carbon black or graphite 15-60 part therein, alkylamide static inhibitor 0.5-5 part, add toughner butylated melamine-formaldehvde resin 5-20 part again, plasticizer phthalic acid diester class 0-10 part, and mixed solvent (ethyl acetate: pimelinketone: 50-200 part acetone=3: 3: 4), through grinding, make the A component after sieving, allocate 60% xylene solution 20-80 part of B component Viscotrol C glycerin modification toluene diisocyanate prepolymer before use into, by the viscosity that mixed solvent is regulated coating, can use second by being coated with 4 glasss of 30-60.
Coating characteristic of the present invention mainly is to rely on carbon black or graphite and alkylamide static inhibitor to reach antistatic property.Wherein have the carbon black of above-mentioned performance or the add-on of graphite and have vital role.This carbon black or graphite are the electronic transfering conductors that is formed by the delocalization of πDian Zi on the fused benzene rings plane net in its structure, when carbon black or graphite-filled in the insulating polymkeric substance after, flow in order to reach the successive electronics, must contact with each other or be in close proximity to each other between carbon black or graphite particle, have only when spacing of particle from less than 10 microns the time, electronics just can pass through the blocking layer of insulating polymkeric substance, so the add-on of carbon black or graphite has a threshold value, after the concentration of carbon black or graphite reaches critical volume concentration, form a unlimited network chain in the system between carbon black or graphite particulate, this network chain plays electric action in superpolymer inside, so resistivity sharply descends.But when carbon black or content of graphite are too high,, cause film performance and conductivity variation because caking agent can not soak into carbon black or graphite particle fully, so forms cavity or tiny crack in the gap of carbon black or graphite.And the alkylamide static inhibitor is a tensio-active agent, and in the coating curing process, lipophilic group inserts the macromolecule layer of coating, hydrophilic radical is arranged in the outside of coating, moisture content in can absorbed air, form visual inspection less than moisture film, thereby increased the conduction of electric charge at coatingsurface.
Coating of the present invention compared with prior art, it is good to have oil-proofness, antistatic property and erosion resistance are strong, stable performance, cost is low, and is cheap, easy construction, long service life, advantage such as safe and reliable can be widely used in the occasion of metallic oil tank inner wall protection.
