Description
Technical field
The invention belongs to heavy-duty coating and field of coating, especially for reparation and other steel construction heavy anti-corrosion paint fields of electric power pylon zinc protective layer (Hot-dip Galvanizing Coating, zinc coating, zinc-rich coating etc.), relate to a kind of zinc and repair coating composition, preparation technology.
Background technology
The zinc protective layer technology such as galvanizing, hot spray painted zinc, electro-galvanizing, zinc-rich paint are widely used in the protection of electric power pylon, in construction, application process, electric power pylon zinc protective layer unavoidably produces the defects such as damaged, first corrosion failure carries out at weakness such as the defect of zinc protective layer, breakages, particularly in the severe rugged environments such as heavy industry zone of pollution, the inefficacy of zinc protective layer is accelerated greatly, the safety of extreme influence electric power pylon is on active service, and is the important leverage that electric power pylon is on active service safely to the timely repairing of this kind of protective layer damaged part.
Carry out application on zinc protective layer surface and play good cathodic protection effect, the zinc-rich paint of close cathodic protection effect of can constructing flexibly, have one of selects.Both at home and abroad zinc-rich paint has been that large quantifier elimination: Schaefer K, Wang Yuchi take in spherical zinc powder, add nano zinc powder respectively, a small amount of spherical zinc powder that adulterates in zinc flake to optimize the mode of electroconductibility between zinc particle, improve the solidity to corrosion of coating; Arianpouya N, Gergely A, Akbarinezhad E take the mode adding the inert filler such as Nano-Zinc and nano clay composition, polypyrrole coated aluminum oxide-multi-walled carbon nano-tubes, polyaniline-nano clay composition and high conductivity substance composite to improve corrosion resistance coating respectively.Surface treatment grade before zinc-rich paint application generally will reach more than St2.5, and under the environment of electric power pylon military service, resource, energy source configuration is not in place, and electric power pylon is complex-shaped, there is no small height on upkeep operation region distance ground, the stress efficacy of power tool and other surface treating appliance is difficult to ensure, the red rust that surface residual after process is certain, white rust, application is carried out on such surface, adhesion strength and the solidity to corrosion of zinc-rich coating cannot be ensured, the research and development of the zinc protective layer reparation coating of low prepared surface are brought into schedule, Gao Xiang, the people such as Chen Yun utilize bi-component epoxide-resin for film forming matter, coupling flake zinc powder, certain research has been done in the organic turn of preparation of rust agent to low prepared surface zinc-rich paint, when neutral salt spray 800h there is corrosion in coating, barrier propterty is far below conventional zinc-rich paint.
Three requirements below the zinc protective layer reparation demand fulfillment of low prepared surface: reparation will have repairing effect to zinc protective layer cathodic protection function; Reparation and zinc protective layer (galvanizing that particularly surface energy is low, pot galvanize, electro-galvanizing) surface will have good consistency and good adhesion property; Reparation and zinc protective layer breakage corrosion iron-based (low-treated surface) well should be adhered to and be had band rust antirust function.Meet these zinc protective layers required and repair coating patents rare report, very necessary with the development that zinc protective layer has better consistency, low prepared surface zinc protective layer that barrier propterty is higher repairs coating.
