Description
Technical field
The present invention relates to a kind of steel pipe piling in ocean, lake and the river etc. and coating and anti-corrosion method of steel sheet pile of being arranged on.
Background technology
General steel pipe piling and the steel sheet pile of using such as the foundation pile of the platform of in ocean, lake and river, building, harbour, dolphin and shore protection.Can adopt cathode protection method preventing corrosion effectively to being immersed in undersurface part for a long time, but for the tidal range district of tidewater fluctuation with waves splash about that district's part then is difficult to adopt this method to prevent corrosion effectively.Relevant traditional anticorrosive measure in this part is mainly taked following three kinds of methods.First method is to adopt to comprise that the cement mortar of concrete coats.But cement mortar coats and can cause the salt concentration in the mortar to become big because of the osmosis of seawater, and pH diminishes, thereby causes the Corrosion Protection of cement mortar to reduce.In addition, cement mortar also exists bending resistance poor, and problems such as be full of cracks take place the vibration when stopping because of boats and ships.Second method is to coat with coating.Representative method is that bottom adopts zinc rich primer in these two kinds of methods, and the top layer adopts epoxypaint to coat.Coating can make steel structure reach the purpose of long-term rust protection.But, when the steel pipe piling of having buried underground is applied, when particularly the tidewater fluctuation partly being applied,, form the fine difficulty of filming very, and corrosion protection result is also not too abundant because of factors such as tidal change and waves.The third method is to adopt the mineral lipid anticorrosion material to coat.This method is to be that the anti-corrosion belt of the sanitas of principal constituent is wrapped on the object with the vaseline with having flooded, and adopts surface that the protective guard made by FRP etc. coats this anti-corrosion belt to protect then, and this method is often used.But; because directly twining anti-corrosion belt at steel surface coats with protective guard then; and the iron and steel of having buried underground is because of surface irregularities such as corrosion and pittings; so can not be fully identical between the surface of anti-corrosion belt and steel; thereby cause the adaptation variation, produce the gap between anti-corrosion belt and the steel.In addition, also can cause this position distortion, so also can cause producing the gap between anti-corrosion belt and the steel because of reasons such as impact from the outside.
Summary of the invention
The coating and anti-corrosion method that the purpose of this invention is to provide a kind of steel.
Technical solution of the present invention is: at the mineral lipid anticorrosion material of steel surface coating pasty state; and the mineral lipid anti-corrosion belt of winding of band-type in the above, further use by protective guard afterwards and be arranged on the plastic foam material of this protective guard internal surface or cushioning material that rubber constitutes coats.Upper and lower end parts at described protective guard is filled curable resin in the water, to seal described mineral lipid anticorrosion material.Has the fixing flange of using in the both sides of described protective guard; on the binding site of this flange; add plate that plastics or fiber-reinforced plastic make between zonal mineral lipid anti-corrosion belt and cushioning material; by flange plate and described zonal mineral lipid anti-corrosion belt are fitted tightly; the bolting flange is used in the fixing middle part of combining site on this plate width with flange of this protective guard.
Described mineral lipid anticorrosion material composition by weight percentage is: mineral fat 10-45%, rust-preventive agent 5-10%, lubricant 30-40%, weighting agent 20-40%; Wherein: described rust-preventive agent is tannic acid and metal-sulfinate, and ratio is 1: 1, and lubricant is a Liquid Paraffin, and weighting agent is lime carbonate or mineral mica.
Described zonal mineral lipid anti-corrosion belt be the thickness that soaked the mineral lipid inhibitor be 1.1-5mm spin cloth or non-woven fabrics; Wherein: spin cloth or non-woven fabrics and make by nylon or polyethylene terephthalate.
Described mineral lipid inhibitor composition by weight percentage is: the mineral fat of 35-68%, the weighting agent of the rust-preventive agent of 1-5%, the lubricant of 10-20% and 20-40%, wherein: rust-preventive agent can be tannic acid, lubricant can be Liquid Paraffin, and weighting agent can be lime carbonate, mineral mica or talcum powder.
The material of described protective guard is an admixture glass fibre in the unsaturated polyester resin.
Adopt the present invention to have following beneficial effect:
1. although the corrosion steel surface is uneven, adopt mineral lipid anticorrosion material of the present invention can cover steel surface comprehensively it is fitted like a glove, compactness is good simultaneously.
2. do not have the space between protective guard of the present invention and the steel, the protective guard inboard can prevent biological breeding, reaches long-term etch-proof purpose.
3., adopt the present invention also can absorb part energy, thereby can prevent that the corrosion protection body that is coated is subjected to damage of external force when even the coating and anti-corrosion body is subjected to the bump of floating matter.
4. because bottom mineral lipid anticorrosion material of the present invention and anti-corrosion belt are with a series of anticorrosives, can bond together each other and become one.
5. the top owing to protective guard can prevent the seawater intrusion, thereby can prevent the damage and the outflow of mineral lipid anticorrosion material.
6. compactness is good between protective guard of the present invention and the baffle plate, is difficult to produce the space and can prevents intrusion, the damage that can prevent mineral substance and the outflow of seawater in protective guard.
Even lining corrosion protection body (as steel pipe piling, steel sheet pile), protective guard and on making some error, also can adjust voluntarily, can reach long-term, efficient, stable anticorrosion ability.
8. because the present invention has added tannic acid and metal-sulfinate in the mineral lipid anticorrosion material, also has good Corrosion Protection in a humid environment.
