The antistatic effect of the paint is long-lasting and effective, fire disasters or explosion caused by sparks produced by static electricity can be avoided, a paint film has excellent oil resistance, and the paint is pollution-free to various oils, and has good corrosion resistance. The paint is applicable to the protection of various oil storage and oil transfer facilities such as oil holds of ships, oil tanks, tank trucks, oil pipelines, and the like.
Description
Technical field
The present invention relates to a kind of protective system and preparation method thereof, particularly basin static electricity conductive anticorrosive paint and preparation method thereof, belong to coating synthesis field.
Background technology
Along with all trades and professions also become increasing to the demand of oil, impel processed oil to transport and store and be further tending towards routinizing, because stored oil product contains hydrogen sulfide, the organic and corrosive chemical such as inorganic salt and water, the life-span of oil tank can shorten greatly.Basin is in transportation simultaneously, the harm of electrostatic is valued by the people, the spark fire hazardous that electrostatic causes and blast, the surface resistivity of standard GB/T 50393 regulation inner wall of petroleum storage tank coating is not more than 1011 ohm, volume specific resistance is not more than 1011 ohm, and the measuring method of GB/T16906-1997 to Oil Tank static conductive coating resistivity has made regulation.Therefore, antistatic coating is applied in the industries such as storage oil transportation facility application more and more widely.
At present, static conductive coating is divided into eigenmode and addition type.Eigenmode is that coating matrix itself has electroconductibility, but price is higher, thus makes to apply and be restricted, and industry actual use be addition type.Namely addition type adds static conducting agent and forms static conductive coating in insulating body coating, and current addition type static conductive coating mainly adds the black static conductive coating of conductive carbon black and adds the static conductive coating of metal conductive powder.The shortcoming that wherein carbon system black static conductive coating exists solidity to corrosion, the galvanic corrosion with the carbon black in coating for anode with iron being negative electrode occurs for ornamental difference and the tank skin of storage tank.Metal addition type electrostatic conductive anticorrosion paint conductive stable, good decorative property.
Domestic metal addition type electrostatic conductive anticorrosion paint conventional at present mainly contains epoxy resin, urethane, inorganic zinc-rich, organic Fu Xin etc.Wherein aqueous inorganic silicate zinc-rich paint is due to its organic solvent-free; there is free from extraneous odour, do not fire not quick-fried; the advantage such as free from environmental pollution; usually be used as the inner surface anticorrosion paint of oil product storage tank; inorganic zinc coating is directly contacted with base material steel surface by zinc powder; and form very strong chemical bonds; and form a battery be made up of zinc powder and substrate steel sheet; because of the electrochemical activity (standard potential is-0.763V) of zinc, comparatively iron (-0.449V) is active; electric current flows to iron by zinc, makes iron and steel be subject to galvanic protection.The present invention take lithium silicate as base-material, with silicon sol, organosilicon crylic acid latex for auxiliary material, take Natvosol as anti-settling agent, methyl tributanoximo silane is under the condition of coupling agent, is uniformly mixed with zinc powder, a kind of basin static electricity conductive anticorrosive paint can be prepared, this coating anti-static effect is long-term lasting effectively, and can avoid the fire that causes because of static-induced spark or blast, film has excellent oil-proofness, pollution-free to various oil product, preservative property are excellent.Be applicable to various oil storage, oil transporting appliance protection, as naval vessel cargo tank, oil tank, trough truck and pipe laying etc.
