Description
Technical field
The invention belongs to technical field of coatings, and in particular to a kind of aqueous inorganic zinc-rich anti-corrosion primer.
Background technology
The phenomenon that metal erosion refers to metal by chemistry or the electrochemical action of surrounding medium and is destroyed.Corrosion causes huge
Big economic loss, according to incompletely statistics, the whole world are lost per the 1/3 of annual steel yield due to corrosion；China it is annual because
Direct economic loss caused by metal erosion accounts for about the 4% of gross national product, and economic loss reaches caused by steel corrosion every year
Trillion yuan, it can be seen that, the protection of corrosion is particularly significant.It was verified that it is most effective, most to carry out anti-corrosion to metal using coating
It is economical, using most common method.Coating to the obstacle that diffuses to form of corrosive medium, the adhesion strength of the matrixes such as coating and steel and
The barrier property of medium plays a crucial role the service life of coating.The corrosion rate of coating depends on：Water passes through diffusion
Oozed coating and in the accumulation of coating/substrate interface and medium ionic by spreading and conduction is oozed overprotection layer and final occurred
Corrosion reaction.Coating mainly shields to base material by barrier and chemical mechanism.

The present invention has the following advantages compared with prior art：Aqueous inorganic zinc-rich anti-corrosion primer prepared by the present invention, not only
With excellent antiseptic property, meanwhile, there is good adhesive force；Aqueous inorganic zinc-rich anti-corrosion primer contains a large amount of metallic zinc
Powder, zinc powder by the collaboration facilitation of modified aerosil can close-packed arrays and contact in the coating, so as to play length
Imitate antisepsis.Aqueous inorganic zinc-rich anti-corrosion primer has following characteristic:Quick-drying, the 20 min surface dryings under standard environment；2h
It does solid work；Thick coated type, disposable spray finishing thickness are excellent up to 70 μm of antiseptic properties；Using water as diluent, cleaning agent is non-ignitable, nothing
VOC emission, construction is simple, storage safety, heat-resisting quantity, continuous heat-resisting reachable 300 DEG C of aqueous inorganic zinc-rich anti-corrosion primers have
Electro-chemical protection, current potential than iron more more negative mechanism, using a large amount of high-purity superfine zinc powder as anti-corrosion more active than iron according to zinc
Pigment makes steel in electrolyte solution, even if coating is locally damaged, since zinc is as sacrificial anode, and obtains steel
To protection, durability is good, by the physics and chemical bonding of coating and steel, makes the strong adhesive force of coating and steel substrate, zinc
The zinc salt and the complex compound of zinc that powder is formed in coating surface can block gap, crackle and the hole of coating, prevent oxygen, water and
The corrosion of other media, and do not influenced by atmospheric conditions and ultraviolet light irradiation, the service life of coating is long, and maintenance cost is low,
It can be suitable for the anticorrosion of steel structure priming paint such as steel tower, pipeline, port facilities, means of transportation, water conservancy projects, need high-temperature corrosion resistance
Under the conditions of iron structure, the iron structure coating under other mal-conditions.
