Abstract
The invention discloses a novel waterborne anti-corrosive modified coating and a preparation method thereof. The preparation method comprises the following steps of pouring a fixed amount of potassium silicate solution and sodium silicate solution into a container, mixing and heating, adding silica sol, uniformly mixing, adding a fixed amount of isopropyl (tri-glycero-acyloxy)-titanate, stirring at high speed, sequentially adding silicone acrylic emulsion and zinc powder, and uniformly stirring, so as to obtain the novel waterborne anti-corrosive modified coating.
Description
Technical field
The present invention relates to a kind of protective system and preparation method thereof, particularly a kind of metal anticorrosion water-soluble coating and preparation method thereof, belongs to coating manufacture field.
Background technology
Along with the progress of science and technology, coating is applied more and more extensive in life, and particularly functional paint, as metal anti-corrosive paint.Coating is a kind of material, and this material can be coated in article surface by different construction technologies, forms adhere well, has some strength, continuous print solid film.The film common name film of such formation, also known as paint film or coating.
Common paint is at steel surface; just prevent steel corrosion in the mode of isolated air; and zinc rich paint not only can completely cut off air; and galvanic cell protection can be formed; comparatively iron and steel is low for the standard potential of the zinc in zinc rich paint, and when corrosive medium infiltrates, iron and steel and zinc powder form galvanic cell; zinc powder loses electronics as the negative pole of galvanic cell, and iron and steel obtains electronics as positive pole and obtains protection.The position had on the film of zinc-rich paint by physical abuse after, in the area of certain limit, anticorrosive current also can flow to iron and steel exposed portion, then the corrosion product of zinc be just deposited on there form layer protecting film.Along with the continuous exposure of steel surface, rich zinc film constantly protected film hidden, and galvanic protection effect just presents inertia again, but then starts when film is subject to physical abuse and exposes new zinc surface to bring back to life.If use sand papering film coated surface, or new zinc face is exposed in film scratch, then potential difference just restores to the original state.In addition, the anion binding in the zine ion be dissolved out and corrosive medium and form basic zinc salt and zinc-iron double salt, fills up the crack of film, and reaches the etch-proof object of isolation.Zinc rich paint is divided into organic zinc rich paint and inorganic zinc-rich paint, and it is film forming binder that organic zinc-rich paint commonly uses epoxy resin, chlorinated rubber, Vinylite and urethane resin.But the poor electric conductivity of the organic binder of organic zinc rich paint.Inorganic zinc-rich paint is divided into again solvent-borne type and water-based two class.Wherein aqueous inorganic zinc rich paint is made up of aqueous inorganic silicate (receive, potassium, lithium) resin, zinc powder, auxiliary agent etc.
Aqueous inorganic zinc-enriched coating 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 simultaneously because solvent is few, wettability is low, and thus sticking power is good not as corresponding solvent based coating, and zinc powder adds in coating, due to zinc powder and the more difficult fusion of inorganic silicate, attached power low with ground.For this reason, the present invention, by dope preparing process, adds a kind of sec.-propyl (three oleophosphoric acid acyloxy) titanate coupling agent, improves the compatibility of metal zinc and silicate, strengthen the sticking power of coating, thus prepare a kind of rich zinc water-based anticorrosive paint of high adhesive force.
Summary of the invention
The object of this invention is to provide a kind of rich zinc water-based anticorrosive paint of high adhesive force, for realizing this purpose, this coating comprises the raw material of following mass percent:
Potassium silicate 5%-10%;
Water glass 5%-10%;
Silicon sol 20%-40%;
Sec.-propyl (three oleophosphoric acid acyloxy) titanic acid ester 5%-10%;
Organosilicon crylic acid latex 20%-30%;
Zinc powder 20%-30%.
A kind of preparation method of rich zinc water-based anticorrosive paint of high adhesive force comprises the steps:
(1) pour a certain amount of potassium silicate solution and sodium silicate solution in container Hybrid Heating, temperature controls at 50-70 DEG C;
(2), under ceaselessly stirring, slowly drip the silicon sol of metering, make it fully mix;
(3) in container, add sec.-propyl (the three oleophosphoric acid acyloxy) titanic acid ester of certain metering again, high-speed stirring;
(4) stop heating, when temperature is down to room temperature, add organosilicon crylic acid latex;
(5) finally add a certain amount of 700 object zinc powders, Keep agitation evenly after a kind of rich zinc water-based anticorrosive paint of high adhesive force.
The present invention has following advantages and characteristic:
(1) attached power good for this coating;
(2) preparation technology is simple, easy to operate.
