Description
Technical field
The invention belongs to technical field of coatings, specifically, being related to a kind of high solid low surface treatment epoxy zinc rich primer
And the preparation method and application thereof.
Background technique
Epoxy zinc rich primer is that one kind is film forming matter and amine using epoxy resin or is modified amine additives as curing agent, is added
Ultra-fine zinc powder and auxiliary agent and solvent are coated in steel substrate surface, play sacrificial anode and protect the steel substrate of cathode
From being corroded, because zinc is more active than iron, when electrochemical reduction oxidation reaction occurs, in anode region, Zn loses electronics and becomes Zn2+
Ion, zinc powder are consumed and corrode, in cathodic region divalent Fe2+Electronics be reduced into Fe, thus cathode be obtained it is etch-proof
Protection.It is widely used in the heavy antisepsis in the fields such as ship, bridge, metallurgy, electric power, petrochemical industry, chemical industry, building machinery and harbour machinery
Erosion protection.
Due to the paint of zinc-rich class, containing a large amount of zinc powder, after paint forms a film, there are many existing hole, disposable to coat
Film thickness it is excessive when, the phenomenon that being easy to produce cracking；In use, along with the consumption of zinc powder, generation it is a large amount of water-soluble
The Zn of property2+, will lead to the increase of osmotic pressure, extremely easily cause getting rusty and blistering for ground, therefore its permanent anticorrosive property
Protective effect be restricted.In addition, will generate a large amount of zinc fume can cause work people during welding and cutting
" the zinc pyreticosis " of member.
The coating of epoxy zinc-rich class mainly includes traditional epoxy zinc rich primer, high solid epoxy zinc-rich, solvent-free ring
Oxygen zinc-rich, water-thinned epoxy zinc-rich, domestic document and patent report also have many reports, such as Publication No.
The patent of invention of CN102533052B discloses a kind of solvent-free type epoxy zinc rich primer and preparation method, volatilizees without solvent,
It is economic and environment-friendly, and salt spray resistance is excellent, but the viscosity of non-solvent epoxy zinc-rich original paint is big, construction is inconvenient, using roller coating
When construction, construction efficiency is low, and when using two-tube charging airless spraying, because to be used in mixed way the phase short for it, is easy to block up rifle；Publication No.
A kind of epoxy zinc rich primer of the patent of invention of CN103483983B and preparation method thereof discloses a kind of solvent type epoxy zinc-rich
Priming paint, solid content is low, VOC content is high, needs to spray the regulation film thickness that the road 2-3 reaches salt spray test template；Publication No.
The patent of invention two-component epoxy zinc rich primer and manufacturing method of CN100451079C, disclosing a kind of Zn content is 80% or more
Epoxy zinc rich primer, antiseptic property is excellent, easy for construction, but the finite thickness of its film, requires surface treatment
It is higher, it has not been convenient to which that maintenance uses.
Therefore, it is necessary to design a kind of new epoxy zinc rich primer, there is solid content height, surface treatment to require low, mixed
Close that working life is moderate, the characteristics of haveing excellent performance, facilitating the maintenance of equipment.
