Abstract
The invention discloses an anticorrosive primer added into a dodecyltrimethoxysilane oil product storage tank. The primer is prepared from the main components of sodium silicate solution, Ludox, silicone acrylic emulsion, phenyltriethoxysilane and superfine zinc powder. The primer can be prepared by performing processes of water-based emulsion, stirring, mixing and the like on the components. The primer is simple in process, convenient to construct and wide in application prospect.
Description
Technical field
The present invention relates to a kind of interior anti-corrosion primer priming paint of oil product storage tank, particularly add anti-corrosion primer and preparation method thereof in high-performance coupling agent, belong to paint process field.
Background technology
Along with the usage quantity of various countries' oil plant is increasing, storage and the transport of oil plant are also increasingly extensive, and stability and the feature of environmental protection of oil product storage tank are also more and more important.Because stored oil product contains hydrogen sulfide, the organic and corrosive chemical such as inorganic salt and water, oil product storage tank can be caused to corrode, corrosion shortens the work-ing life of oil tank, if rotproofing timely can not be carried out to metallic oil tank, also can pollute oil product, affect oil quality; Heavy then cause oil leak because corrosion makes oil tank bore a hole, and easily cause fire, blast, its danger is well imagined.Oil product storage tank aseptic technic is one of studying a question of being concerned about of people always.
At present, the aseptic technic of oil tank mainly adopts metal spraying genus, galvanic protection and coating antifouling paint etc.Wherein antifouling paint is the most extensive; the conventional main rich zinc antifouling paint of antifouling paint; zinc rich paint 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, and electric current flows to iron by zinc, makes iron and steel be subject to galvanic protection.Zinc rich paint has 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 interior anti-corrosion primer of oil product storage tank, but compared with other organic anti-corrosive priming paint, this coating wettability is low, sticking power is good not as other solvent based coating, and zinc powder adds in coating, the stability that zinc powder and inorganic silicate merge is not enough, easily causes layering uneven.In order to overcome with the shortcoming of upward stability deficiency, the present invention is by oil product storage tank in anti-corrosion primer preparation process, add dodecyltrimethoxysilane coupling agent, improve the compatibility of metal zinc and silicate, strengthen the sticking power of paint, thus prepare the interior anti-corrosion primer of oil product storage tank of a kind of strong adhesion, free from environmental pollution, easy construction.
Summary of the invention
The object of this invention is to provide a kind of interior anti-corrosion primer of oil product storage tank, for realizing this purpose, the preparation method of the interior anti-corrosion primer of this oil product storage tank comprises the steps:
(1) by a certain amount of solid content be 35% sodium silicate solution pour into and be equipped with in high speed agitator container, under the condition constantly stirred, slowly add the silicon sol of metering;
(2), after dripping silicon sol, system is heated;
(3) when being heated to temperature to 60-70 DEG C., more slowly organosilicon crylic acid latex is dripped in container;
(4), after dripping organosilicon crylic acid latex, stop heating, and high-speed stirring for some time;
(5) add a certain amount of super-fine zinc dust again;
(6) finally add a certain amount of dodecyltrimethoxysilane coupling agent, Keep agitation evenly after a kind of interior anti-corrosion primer of oil product storage tank of stability excellence.
The present invention is in oil product storage tank in anti-corrosion primer preparation process, and the addition of sodium silicate solution accounts for the 20%-30% of system.
The present invention is in oil product storage tank in anti-corrosion primer preparation process, and the addition of silicon sol accounts for the 15%-20% of system.
The present invention is in oil product storage tank in anti-corrosion primer preparation process, and the addition of organosilicon crylic acid latex accounts for the 10%-20% of system.
The present invention is in oil product storage tank in anti-corrosion primer preparation process, and the addition of dodecyltrimethoxysilane coupling agent accounts for the 2%-4% of system.
The present invention is in oil product storage tank in anti-corrosion primer preparation process, and the addition of the zinc powder added accounts for more than 40% of system, and is greater than 350 orders.
The present invention has following advantages and characteristic:
(1) the PASS prepared is strong;
(2) free from environmental pollution, easy construction.
