Description
Technical field
The present invention relates to a kind of thin graphene dispersed paste, preparation method and applications for anticorrosive paint, belong to
Nanotechnology and paint field.
Background technique
In recent years, with the rapid development of economy, Building Trade in China, rail traffic, municipal works, energy industry need
It wants.China's steel construction industry is in fast development period.Ship, bridge, large-scale stadium, subway, airport, railway station,
Petroleum works equipment, steel house, steel structure bridge, offshore platform, military installations etc. have large area to use steel construction material
Material.But the poor corrosion resistance of steel, it is necessary to take safeguard procedures, prevent corrosion of steel from getting rusty, just can ensure that steel construction is being set
Count the safety in validity period.China causes a large amount of resource wave every year because corrosion causes steel loss more than 60,000,000 tons
Take, economic loss is huge.Applying anticorrosive paint is current the most frequently used, most effective steel corrosion safeguard procedures, and common anti-corrosion applies
Material is mainly the anticorrosive coatings such as inorganic zinc-rich, epoxy zinc-rich, epoxy micaceous iron, chlorinated rubber iron oxide red, these anticorrosive coatings are very
Solves the problems, such as the corrosion protection of steel in big degree, but the service life phase is shorter in harsh marine environment.Marine environment
Middle steel construction is influenced by seawater immersion, salt air corrosion, hot and cold alternation, alternation of wetting and drying for a long time, and corrosion of steel structure is serious, and
These position inspection and maintenances are inconvenient, coating condition is poor, and structure is complicated, are not easy to maintenance coating.Traditional anticorrosive paint anti-corrosion
Erosion phase effect is short, it is difficult to meet the long-term anticorrosion requirement of marine environment, more stringent requirements are proposed to anticorrosive paint.
Thin graphene is a kind of important new function material, it is carbon atom with sp2The hexatomic ring knot that hydridization is formed
Structure, with superelevation specific surface area, chemical property stablize, while have efficient barrier property, electric conductivity, chemical resistance corrosivity,
The excellent physicals chemical property such as high-temperature stability, thin graphene, which is used for anticorrosive paint, can break through original special functional coating
Technology limitation, prepares more efficient anticorrosive paint.Research both domestic and external shows that thin graphene can be made by shielding
The electric action performance antiseptic property cooperated with and with zinc powder.However thin graphene piece is because interlayer van der Waals interaction holds
It is easy to reunite to be difficult to disperse, and the poor compatibility with resin, defect, influences coating property instead once being formed.Thin graphene
Multiple preparation technologies, the number of plies, piece diameter, functional group etc. all affect dispersibility and anti-corrosion effect of the thin graphene in coating.
Meanwhile the simple antisepsis for relying on thin graphene cannot still reach optimal anti-corrosion effect.
Summary of the invention
It is existing to overcome the main purpose of the present invention is to provide a kind of thin graphene dispersed paste and preparation method thereof
