Description

A kind of corrosion of metal structure damaged composite material bonding repair method
Technical field
The invention belongs to Metal Structure Damages to repair field, and specifically a kind of corrosion of metal structure damaged composite material is viscous Connect repair method.
Background technique
Metal structure by surrounding medium chemical action or electrochemical action and corrode, the generation of corrosion not only can Direct economic damage is brought, and ecological environment can be destroyed.After metal structure is corroded, corrosion product and ontology are detached from It will lead to structural section thickness to become smaller, structural-load-carrying capacity decline.If handled not in time, corrosion can further develop, finally Lead to structural failure.Although having put into the corrosion protection of metal structure very much, it is difficult to avoid corruption completely The generation of erosion.It after corrosion occurs, places under repair in time to structure, restores structural-load-carrying capacity, and corresponding anticorrosion is taken to arrange It applies most important for the service life of extending structure.
After corroding at present for metal structure, if corrosion damage size is more than damage tolerance, machine is generallyd use The mode that tool is repaired reinforces structure, and carries out corrosion protection.If mainly taking corruption without departing from damage tolerance Lose safeguard procedures.Metal reinforcing plates are connected to corrosion damage knot by repair of machine, the form mainly taking riveting or being spirally connected Structure, to restore the bearing capacity of structure.Rivet, be spirally connected repairing need drill on original structure, be bound to cause structure in this way Secondary damage, and repair construction and need certain space.It just needs detaching structure in order to obtain construction space or opens fabrication hole, The time for repairing construction in this way will extend.Although after repairing, safeguard procedures can be taken to prevent the generation of corrosion, one In a little rather harsh environments, for example, high temperature and humidity marine environment with high salt or the direct structure used in the seawater, corrosion Usually also occur that.At this point, main measure is exactly to reinforce checking and constantly be protected.It is undoubtedly will increase in this way using dimension The cost of shield.Therefore, the repair method that can restore structural strength and excellent Corrosion Protection well is taken, it is right It is very significant in corrosion of metal structure damage repair.
It is that composite material laminated board sticking patch is adhered in damaged metal structure that composite material bonding, which is repaired, plays recovery knot The effect of structure intensity.It is secondary with avoiding relative to traditional mechanical connection repairing that composite material bonding repairs damaged metal structure It damages, slow down stress concentration, improve corrosion-resistant and fatigue performance, weight increases few, outstanding advantages of designability is strong.More It is important that composite material itself has very excellent corrosion resistance, moreover, composite panels are adhered to metal structure After upper, damaged structure and external environs also can be avoided corroding again by bonding region.This patent is just to provide one The composite material of kind metal erosion damaged structure is bonded repair method.

Optionally, for wet-laid process, when selecting carbon cloth, it is necessary to which laying layer of glass cloth first makes metal knot Structure and carbon cloth are kept apart.
Optionally, the sequence of the laying be according to sticking patch laying size from big to small, or from small to large.
Optionally, the solidification of the composite panels uses and vulcanizes instrument in-situ solidifying, or damaged structure is dismantled down Come, solidification is completed using autoclave or Electric heat oven and vacuum pump.
Optionally, specific steps include the following:
1) corrosion damage is handled, it is thoroughly clear using mechanical grinding or the method for mechanical grinding combination chemical reagent Except corrosion product;
2) corrosion area after removing corrosion product is surface-treated;
3) etch pit is filled: by the tree of deployed resin or glass fibre or metal powder reinforcement added with chopping Rouge material is filled into etch pit, is smeared smooth;
4) after resin filling solidification, at polishing finishing filling, keep it concordant with metal structure face, repaired in order to implement bonding Reason;After finishing, start bonding composites laminate sticking patch;
5) after the solidification for completing composite panels, polishing finishing is carried out, and restore metal structure surface protective layer.
Optionally, in step 2), specific steps include sandblasting, apply coupling agent.
A kind of corrosion of metal structure damaged composite material of the invention is bonded repair method, produced compared with prior art Beneficial effect be:
The present invention is directed to structure erosion injury region potting resin material, in conjunction with adhesive composite materials laminate sticking patch, carries out It emergency repair and usually repairs, not only having can be avoided secondary damage, slows down stress concentration, improve corrosion-resistant and fatigue durability Outstanding advantages of energy, weight increase less, and designability is strong, for the bigger damage of corrosion size, additionally it is possible to meet and corrode damage The rigidity requirement of injury.
