Abstract
The invention discloses inorganic storage tank modified anti-corrosion paint added with methyltrimethoxysilane and a preparation method of the paint. The paint is mainly prepared from a sodium silicate solution, silica sol, silicone acrylic emulsion, the methyltrimethoxysilane and zinc powder. The preparation method of the paint comprises the steps that a certain amount of the sodium silicate solution is contained in a container provided with a stirrer, and the solution is mixed with the silica sol through a stirring technology; after the mixture is heated to certain temperature, the silicone acrylic emulsion is dropwise added to the system, and then the system is cooled to room temperature; finally, the ultrafine zinc powder and the methyltrimethoxysilane are sequentially added and stirred to be uniform, and the inorganic storage tank modified anti-corrosion paint with the excellent property can be obtained.
Description
Technical field
The present invention relates to a kind of oil product storage tank modification antifouling paste, particularly add modification antifouling paste of methyl three TMOS coupling agent and preparation method thereof, belong to paint process field.
Background technology
For the petroleum chemicals such as crude oil, processed oil, Sweet natural gas transport, store transfer and all need to build the steel structure device such as storage tank, all there is harsh corrosion in these devices, must take necessary anti-corrosion measure.Special in oil product storage tank, if rotproofing timely can not be carried out to metal tank, 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 corrosion process is generally by two kinds of approach.One is chemical corrosion, mainly by corrosion that metallic surface and surrounding medium directly chemical reaction occur and cause; Another is galvanic corrosion, mainly metallic substance (alloy or impure metal) and electrolyte solution contacts, the corrosion produced by electrode reaction.
At present, conventional antifouling paint mainly contains rich zinc antifouling paint, due to the zinc powder filler that rich zinc antifouling paint adopts a large amount of high purities, particle thin, can play electro-chemical protection.Zinc is more bold and vigorous than ironwork, and current potential is more negative than iron, and in electrolyte solution, zinc atom easily loses electronics; even if coating local is all destroyed, steel surface is not also corroded, because zinc plays the effect of sacrificial anode; positive column betatopic, cathodic area obtains electronics, thus makes iron and steel protected.
Zinc rich paint has inorganic zinc rich paint and organic zinc rich paint.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, but compared with other organic anti-corrosive paint, this paint wettability is low, and sticking power is good not as other solvent-based paints, and zinc powder adds in inorganic solution, 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 inorganic storage tank antifouling paste preparation process, add methyltrimethoxy silane coupling agent, improve the compatibility of metal zinc and silicate, strengthen the sticking power of paint, thus the inorganic storage tank modification antifouling paste prepared and steel surface sticking power good, heat-resisting and not easily occur aging, there is excellent weathering performance.
Summary of the invention
The object of this invention is to provide a kind of inorganic storage tank modification antifouling paste adding methyltrimethoxy silane, it is as follows that its each component concentration accounts for system:

For preparing this inorganic storage tank modification antifouling paste, its preparation method comprises the steps:
(1) the container being configured with high speed agitator with loads a certain amount of sodium silicate solution, starts agitator, more slowly adds appropriate silicon sol;
(2), after silicon sol adds end, system is heated;
(3) in container, slowly drip organosilicon crylic acid latex again;
(4), after dripping organosilicon crylic acid latex, be down to room temperature, 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 methyltrimethoxy silane coupling agent, Keep agitation evenly after a kind of inorganic storage tank modification antifouling paste of excellent performance.
