Description
Technical field
The present invention relates to the correlative technology field of corrosion resistant coating, more particularly, it relates to a kind of corrosion resistant coating preparation technology.
Background technology
Iron and steel in our lives purposes widely, such as auto industry, manufacturing industry, building industry, transportation are capable
Industry, but iron and steel rotproofness is poor, and corrosion resistant coating is extremely important for iron and steel, according to statistics, every year due to corroding the iron and steel for causing
Loss accounts for the 10%～20% of annual production, and corrosion is usually that generation is chemical or how contrary electrochemistry is between metal surface and medium
Should cause, the mechanical properties such as intensity, the toughness of ferrous materials can be significantly reduced after corroding, destroy the geometry of hardware
Shape, shortens the service life of equipment, is that this people prevents or delay corrosion by corrosion resistant coating.
The concept of corrosion resistant coating (duty paint), refers generally to be used in harsh corrosive environment, including priming paint and finish paint
Matched coating.Corrosion resistant coating extensively South China of North China using positive Europe series art coatings be a kind of new wall decoration
Art paint, and passed through ISO9001 Quality Management System Certifications and ISO14001 environment management system certification along with modern high
The handling process of science and technology, makes product nontoxic, environmental protection, while being also equipped with waterproof, dust-proof, the function such as combustion, high-quality art coatings can be washed
Brush, rub resistance, color for a long time Chang Xin.Briefly:Corrosion resistant coating is exactly that service life is longer, is suitable for harsher use environment
Coating be referred to as corrosion resistant coating.
Corrosion resistant coating paint film prevents corrosive medium and material surface contact；The path of cut-off corrosion cell, increases resistance.Such as
Epoxy coal asphalt paint, epoxy glass squama antiseptic paint paint, chlorosulfonated polyethylene paint, polyureas, acrylic polyurethane coating etc..Corrosion resistant coating
The corrosion factors such as flake pigment energy shield water, oxygen and ion are passed through.The coating that resin and pigment are formed extends corrosive medium and penetrates into
Approach, so as to improve coating corrosion resistant coating lose ability.
Common corrosion resistant coating mainly reaches the purpose of corrosion resistant coating in terms of two：One is with shielding action, the resistance of corrosion resistant coating paint film
Only corrosive medium and material surface contact, separate the path of corrosion cell, increase resistance.Such as epoxy coal asphalt paint, epoxy glass
Glass squama antiseptic paint paint, chlorosulfonated polyethylene paint, polyureas, acrylic polyurethane coating etc.；Another is corrosion inhibition, corrosion resistant coating
Some pigment, or itself and film forming matter or the product of moisture, corrosion inhibition (including passivation), such as phosphatization can be played to ground metal
Priming paint, phosphatization, zinc-plated chromium plating, epoxy phosphate yellow zinc chromate primer paint etc..But both corrosion resistant coating corrosion resistant coating effects are limited, and with negative electrode guarantor
Shield effect carrys out corrosion resistant coating, and more preferably, such as zinc rich paint contains a large amount of zinc powders to corrosion resistant coating effect in zinc rich paint, between zinc particles, zinc
It is in close contact between particle and steel surface, the current potential of zinc is more negative than ferrum, so zinc atom easily loses in electrolyte solution
Electronics becomes anode, and iron rule is negative electrode.In anode region, zinc is corroded due to losing electronics, and on cathode chamber, steel surface is continuous
Electronics is obtained, so as to be protected.After having site tissue damage on film, expose parent metal, in less area internal corrosion electricity
Stream can flow to iron and steel exposed portion, then the product of zinc is deposited upon being here formed as layer protecting film, delay corrosion to continue generation.
Zinc rich paint is divided into organic zinc rich paint and inorganic zinc-rich paint, and organic zinc rich paint commonly uses epoxy resin, chlorination
Rubber, vinylite and polyurethane resin are film forming binder.But the electric conductivity of the organic binder of organic zinc rich paint is poor.
Inorganic zinc-rich paint is divided into again solvent-borne type and the class of aqueouss two.Wherein aqueous inorganic zinc rich paint is by aqueous inorganic silicate
The composition such as (receive, potassium, lithium) resin, zinc powder, auxiliary agent.Aqueous inorganic zinc rich paint due to its organic solvent-free, with free from extraneous odour, no
Combustion is not quick-fried, the advantages of free from environmental pollution, but the wild effects such as sedimentation occurs in waterborne zinc-rich paint preparation process.
The content of the invention
In view of this, the technical problem to be solved in the present invention is to overcome the wild effects such as sedimentation to provide a kind of anti-corrosion

Further, also include adding the process of magnesium stearate in step 5.
Further, the mass percent of the zinc powder of addition is 10%～15%.
The present invention provide a kind of corrosion resistant coating preparation technology be relative to the beneficial effect of prior art：
Corrosion resistant coating work flow is simple and convenient, and the good product quality produced and abrasion resistance are strong, saves production cost,
And low in raw material price, performance is good, and clean environment firendly meets the demand of users.
Meanwhile, the preparation method of this kind of corrosion resistant coating more adapts to the epoch of the progress at full speed of current industrialized production, solves
Paint deterioration, the problem of pollution, this product collection resources conservation, environmental friendliness, recycling, in integration, is industrial metaplasia
Produce requisite product.
Further, sedimentation phenomenon occurs in existing waterborne zinc-rich paint preparation process, in order to overcome disadvantage mentioned above,
