Abstract
The invention relates to a metal antirust functional coating doping with vinyltri (2-methoxyethoxy) silane. Through doping the vinyltri (2-methoxyethoxy) silane in the preparation process of a water-based inorganic zinc-rich metal antirust functional coating, the fusion of zinc powder and inorganic silicate is promoted, and the stability and adhesive force of the coating are improved, so that the coating has excellent stability. The preparation process is simple and the price is low.
Description
Technical field
The present invention relates to a kind of functional paint and preparation method thereof, particularly a kind of metal rust preventing functional paint and preparation method thereof of the silane coupling agent that adulterates, 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.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 coating, 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 coating is divided into again solvent-borne type and water-based two class.Wherein aqueous inorganic zinc-enriched coating 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, zinc powder and the more difficult fusion of inorganic silicate, coating stabilization performance is not enough.For this reason, the present invention, by dope preparing process, adds vinyl three (2-methoxy ethoxy) silane coupling agent, improves the compatibility of metal zinc and silicate, strengthen the sticking power of coating, thus the rich zinc functional paint of the metal rust preventing preparing a kind of stability excellence.
Summary of the invention
Rich zinc functional paint of metal rust preventing that the object of this invention is to provide a kind of stability excellence and preparation method thereof, 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%;
Vinyl three (2-methoxy ethoxy) silane coupling agent 5%-10%;
Organosilicon crylic acid latex 20%-30%;
Zinc powder 20%-30%.
A kind of preparation method of the rich zinc functional paint of metal rust preventing of stability excellence 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, spray vinyl three (2-methoxy ethoxy) silane coupling agent of certain metering again in batch mixing, 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 600 object zinc powders, Keep agitation evenly after a kind of rich zinc functional paint of metal rust preventing of stability excellence.
The present invention has following advantages and characteristic:
(1) it is good that stability by the coating prepared;
(2) cheap, and environmental protection.
