Abstract
The invention aims at providing a novel oil-resistant tank electrostatic conducting anticorrosive paint. Lithium silicate is taken as a silicate base stock, and is mixed with zinc powder under the action of an anti-settling agent, a coupling agent and other assistants; the oil-resistant tank electrostatic conducting anticorrosive paint can be prepared through certain heating and stirring technologies. The paint is good in oil resistivity, high in adhesive force, and convenient to construct, and does not pollute the environment.
Description
Technical field
The present invention relates to a kind of protective system and preparation method thereof, particularly a kind of basin static electricity conductive anticorrosive paint and preparation method thereof, belong to coating synthesis field.
Background technology
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, and the harm of electrostatic is valued by the people, the spark fire hazardous that electrostatic causes and blast.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, dimethyldimethoxysil,ne 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.
Summary of the invention
The object of this invention is to provide a kind of novel oil-proofness basin static electricity conductive anticorrosive paint and preparation method thereof, for realizing this purpose, the preparation method of this coating comprises the steps:

(2), after dripping silicon sol, system is heated;
(3), when Heating temperature is to 60-70 DEG C, in container, drip organosilicon crylic acid latex;
(4), after dripping organosilicon crylic acid latex, stop heating, and high-speed stirring for some time;
(5) add again and be a certain amount ofly greater than 300 object zinc powders;
(6) finally add a certain amount of Natvosol, dimethyldimethoxysil,ne coupling agent successively, Keep agitation evenly after a kind of oil-proofness basin static electricity conductive anticorrosive paint.
