Abstract
The invention relates to a lightweight calcium stearate-containing anticorrosive paint and a preparation method thereof. Material particles easily settle and are unstable in the preparation process of common anticorrosive paints. Lightweight calcium stearate is nontoxic and has excellent lubricity, so calcium stearate is added in the preparation method of the anticorrosive paint in order to improve the stability of the paint as a good stabilizer.
Description
Technical field
The present invention relates to a kind of antifouling paint and preparation method thereof, particularly a kind of antifouling paint adding stearate and preparation method thereof, belong to paint chemical field.
Background technology
Many article in the work environment; the various corrosion of easy generation; in order to make material durable more; through being everlasting, material surface coats layer protective layer; to reach the object preventing from or delay corroding; antifouling paste be used in body surface can be used for protect interior of articles be not corroded one class paint, it is widely used in the fields such as aviation, boats and ships, chemical industry, oil pipeline, bridge.
Anticorrosion concerning extremely important especially metal iron and steel, 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, 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 sedimentation phenomenon, in order to overcome above shortcoming, in paint preparation process, adding people's lightweight calcium stearate stablizer, in paint, namely introduce loose webs thixotropy structure, prevent from expecting particles settling, improve the stability of paint.
Summary of the invention
The present invention discloses and a kind ofly adds antifouling paint of lightweight calcium stearate and preparation method thereof, and contained by this paint, the mass percent of component is:
Potassium silicate 20%-30%;
