Description
Technical field
The present invention relates to a kind of preservative property coating, particularly a kind of maritime works's reinforced concrete protective system and preparation method thereof, it is applicable to that anticorrosive construction is carried out on wet surface in the tidal range district.
Background technology
At present, maritime concrete rot-resistant present situation is: be in the sea port dock that wave spatters the district, because the salinity in seawater and the misty rain is a strong corrosive material; CO in the atmosphere
2, acid rain can make concrete (concrete structure) because of carbonization neutralization loses provide protection to reinforcing bar, causes reinforcement corrosion, and then make the concrete spalling, peel off, until structure deteriorate.The destroying concrete structure that reinforcement corrosion causes is quite general and serious.China has built the harbour concrete structure because of causing steel bar corrosion in the chlorion infiltration concrete before 1986, causes concrete member cracking destruction situation very serious.Its reason is except construction quality exists certain problem, and another principal element is that at that time chlorion to be invaded the seriousness understanding that causes steel bar corrosion not enough.
Along with high speed development of national economy in recent years, the prevention of marine concrete structures weather resistance is had higher requirement.In recent years many heavy constructions of Xing Jianing have all proposed to be no less than the requirement in work-ing life of 50 years even 100 years.Adopt anticorrosive coating protection concrete structure to become the key areas that the anticorrosive coating technology is used.
At publication number is in the Chinese invention patent " the modified epoxy ceramic coating and the manufacture method of seawater corrosion resistance " of CN101074339, discloses a kind of modified epoxy ceramic coating and manufacture method of seawater corrosion resistance:
" this invention is by E52 Resins, epoxy, Nuo Fuleke Resins, epoxy, mixed solvent, composite assistant, forms A liquid through the aluminum oxide powder mixed ceramic powder of silica flour, mullite powder and the alpha-crystal form of the different-grain diameter of activation treatment; the reactive hydrogen equivalent that is generated by aliphatic cyclic amine and cardanol, formaldehyde reaction is that 76～78 pnenolic aldehyde amine hardener is formed B liquid, during use with A liquid and B liquid mixing formation.Coating can be in low-temperature curing, has good storing stability, have splendid sticking power, wear resistance, thermotolerance, solvent resistance, saturated sodium-chloride that can be anti-100 ℃, bittern or synthetic sea water corrode, and can be used for the internal and external anti-corrosive erosion resisting coating of maritime works's steel structure, sea container and seawater transport pipe." though this invention also can play certain preservative activity,, it is not suitable in the tidal range district wet surface and carries out anticorrosive construction, can not solidify drying and forming-film in water, and color is single, can not satisfy different customer demands and beautifies the environment, and the anticorrosion life-span is shorter.Therefore, this invention and be not suitable for the anticorrosion of maritime concrete.
