Abstract
The invention provides composite silicate zinc-rich paint and a preparation technique thereof. The technique comprises the following steps of mixing and heating a potassium silicate solution and a sodium silicate solution, and then dropwise adding a silica sol and a silane coupling agent into an obtained mixture in an agitation condition, uniformly mixing a newly obtained mixture, afterwards, cooling the newly obtained mixture to a room temperature, adding a silicone-acrylic emulsion into the cooled newly obtained mixture, finally adding superfine zinc powder into a finally obtained mixture, continually agitating a final product to obtain the composite silicate zinc-rich paint. The paint is simple in preparation technique, is good in operability, and has a wide application prospect.
Description
Technical field
The present invention relates to a kind of metal anti-corrosive paint, particularly a kind of take silicate as the zinc rich paint of base-material, belongs to paint chemical field.
Background technology
Metallic corrosion is an important factor in order of the metal lost of life, according to statistics, the metal that the whole world is scrapped because of corrosion every year reaches more than hundred million tons, the iron and steel loss caused due to metallic corrosion every year accounts for 10 ~ 20% of output of steel then, and the indirect losses such as the stopping production that metallic corrosion accident causes, power failure just more cannot calculate.The corrosion of metal is modal etch state.During corrosion, the interface of metal there occurs chemistry or electrochemistry heterogeneous reaction, make metal proceed to oxidation (ion) state.This significantly can reduce the mechanical property such as intensity, plasticity, toughness of metallic substance, destroy the geometrical shape of hardware, increase the wearing and tearing between part, worsen the physicals such as electricity and optics, in the work-ing life of shortening equipment, even cause the catastrophic failure such as fire, blast.
People delay corrosion of metal speed by various mode, as improved base material, selecting anticorrosive, increase metal plating, add inhibiter, adopting electro-chemical protection.People, by adding other materials to suppress in pure metal or stoping corrosion of metal, achieve success in various degree.But the shortcoming adopting the material being less likely to occur to corrode to solve etching problem is and original metallographic phase ratio, and its physicals often lacks to some extent, or causes cost to increase due to the cost of alloy.Therefore the most frequently used anti-corrosion mode is exactly to needing the additional top coat having a tolerance of the metal of protection.
Zinc rich paint is coated in steel surface, greatly can extend the work-ing life of steel construction.Due to the standard potential of zinc, comparatively iron and steel is low, and when corrosive medium infiltrates, iron and steel and zinc powder form galvanic cell, and 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.Be used alone a kind of silicate as base-material, its Performance comparision is single, and the present invention, by mixing potassium silicate and Gui Suan Na, using this mixed silicate as base-material, prepares a kind of zinc rich paint of excellent properties.
