Technical field
The present invention relates to organic zinc-rich paint technical fields, apply more particularly, to a kind of organic zinc-rich of aqueous one-component
Material and its preparation method and application.
Background technique
In heavy antisepsis field, aqueous double-component zinc-rich paint is widely used because of its excellent antiseptic property.Mesh
Before, it the use of most common aqueous double-component zinc-rich paint is double-component aqueous epoxy zinc-enriched paint, double-component aqueous epoxy zinc-rich
Coating is generally included by the component A that forms of part such as liquid epoxies, zinc powder, dispersing agent, anti-settling agent, solvent and aqueous solid
The B component of agent composition.Aqueous double-component zinc-rich paint needs two components to mix in the construction process, rapid construction, working life
Later, coating fails.The working life of aqueous double-component zinc-rich paint is shorter, is unfavorable for subsequent construction, improves the time of construction
It is required that increasing the difficulty of construction.
And aqueous one-component organic zinc-rich paint then can preferably solve being applicable in for aqueous double-component organic zinc-rich paint
Phase short problem.But the high activity of zinc powder limits application of the zinc powder in aqueous one-component coating.Common zinc powder can be with
Moisture reacts, and generates hydrogen, causes coating to be easy flatulence during storage, is unfavorable for single-component water-based zinc-rich paint
Storage stability.So current few aqueous one-component zinc-rich paint.
