Abstract
The invention relates to water-based inorganic anti-corrosive paint added with aluminum stearate. The preparation method of the paint comprises the following steps: taking a proper amount of sodium silicate solution, pouring into a container capable of being heated, slowing heating by using a heat source, adding silicone acrylic emulsion when the temperature is increased to be about 70 DEG C, fully mixing, then, and stopping heating; sequentially adding a titanate coupling agent and zinc powder, and stirring and mixing in an accelerating manner; finally, adding MgCl2 aqueous solution and aluminum stearate, and uniformly mixing. According to the invention, as the aluminum stearate has good lubricity, the stability of the paint can be greatly improved through adding the aluminum stearate into the anti-corrosive paint; besides, the preparation technology is simple, and the anti-corrosive paint has better application prospect.
Description
Technical field
The present invention relates to a kind of antifouling paint and preparation method thereof, particularly a kind of rich zinc antifouling paint of aqueous inorganic adding stearate and preparation method thereof, belongs to paint chemical field.
Background technology
Iron and steel we life in purposes widely, as automotive industry, production, construction industry, the industries such as transportation, but iron and steel rotproofness is poor, anticorrosion concerning extremely important iron and steel, according to statistics, the 10%-20% of annual production is accounted for every year owing to corroding the iron and steel loss caused, corrosion is generally that between metallic surface and medium, generation chemistry or electrochemistry heterogeneous reaction cause, the intensity of ferrous materials significantly can be reduced after corroding, the mechanical properties such as toughness, destroy the geometrical shape of hardware, the work-ing life of shortening equipment, people are prevented by antifouling paint or delay corrosion for this reason.
Common antifouling paint mainly reaches rot-resistant object from two aspects: one is with shielding effect, and antifouling paint paint film stops corrosive medium and material surface contact, cuts off the path of corrosion cell, increases resistance.As epoxy coal asphalt paint, epoxy glass squama antiseptic paint, chlorosulfonated polyethylene paint, polyureas, acrylic polyurethane coating etc.; Another is corrosion inhibition, some pigment of antifouling paint, or the reaction product of itself and film forming matter or moisture, can play corrosion inhibition (comprising passivation), as wash primer, phosphatization, zinc-plated chromium plating, epoxy phosphate yellow zinc chromate primer paint etc. to ground metal.But these two kinds of antifouling paint preservative effects are limited; and be used for anticorrosion with galvanic protection; preservative effect is better; as zinc rich paint; containing a large amount of zinc powder in zinc rich paint, close contact between zinc particles, between zinc particles and steel surface, the current potential of zinc is more negative than iron; so zinc atom easily loses electronics and becomes anode in electrolyte solution, iron rule is negative electrode.In positive column, zinc is corroded owing to losing electronics, and in cathodic area, steel surface constantly obtains electronics, thus is protected.After film has site tissue damage, expose matrix metal, can flow to iron and steel exposed portion at less area internal corrosion electric current, then the product of zinc is just deposited on and forms layer protecting film herein, delays corrosion and continues to occur.
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 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 in waterborne zinc-rich paint preparation process, there will be the wild effects such as sedimentation, in order to overcome above shortcoming, in paint preparation process, adding people's aluminium octadecanoate stablizer, in the rich zinc antifouling paint of aqueous inorganic, introducing loose webs thixotropy structure, prevent from expecting particles settling, improve the stability of paint.
Summary of the invention
Add an aqueous inorganic antifouling paint for aluminium octadecanoate, its preparation method comprises the steps:
(1) a certain amount of sodium silicate solution is poured in container, slowly heat;
(2) when being heated to 60-75 DEG C, organosilicon crylic acid latex is slowly added in container, and ceaselessly stir, after interpolation, stop heating;
(3) in container, add appropriate titanate coupling agent again, high-speed stirring;
(4) add zinc powder, ceaselessly stir;
(5) finally add appropriate MgCl successively
2the aqueous solution and aluminium octadecanoate, obtain a kind of aqueous inorganic antifouling paint adding aluminium octadecanoate.
Preferential, step (4) in, added zinc powder is 500-600 order, and interpolation mass percent is 45%-60%.
Preferential, step (5) in, the interpolation mass percent of aluminium octadecanoate is 4%-6%.
The present invention has following advantages and characteristic:
(1) preparation technology is simple;
(2) paint stabilization is good.
