Abstract
Inorganic storage tank modified anticorrosion paint comprising sulfur-containing silicane is disclosed. The paint comprises 20-30% of a sodium silicate solution, 15-20% of silica sol, 10-20% of silicone acrylic emulsion, 2-4% of bis[3-(triethoxysilyl)propyl]tetrasulfide and not more than 40% of zinc powder. By adding the bis[3-(triethoxysilyl)propyl]tetrasulfide which is a coupling agent into a preparation process of organic storage tank anticorrosion paint, adhesive force of the paint is improved, so that the prepared inorganic storage tank modified anticorrosion paint is high in adhesive force with steel surfaces, heat-resisting and not liable to age.
Description
Technical field
The present invention relates to a kind of inorganic storage tank modification antifouling paste, particularly add modification antifouling paste of polysulfur silane coupling agent and preparation method thereof, belong to paint process field.
Background technology
For transport, the storage transfer of the petroleum chemicals such as crude oil, processed oil, Sweet natural gas, all needing to build the steel structure devices such as storage tank, all there is harsh corrosion in these devices, must take anti-corrosion measure that is necessary, science.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 two-(γ-triethoxysilylpropyl)-tetrasulfide 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.
Summary of the invention

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;
Last add a certain amount of two-(γ-triethoxysilylpropyl)-tetrasulfide coupling agent, Keep agitation evenly after a kind of inorganic storage tank modification antifouling paste of excellent performance.
