Description
Technical field
There is antisepsis, set for railway line bridge the present invention relates to anticorrosion of steel structure technical field, more particularly to one kind
Zinc alkene anticorrosive paint in standby steel construction workpiece.
Background technology
Because railway facilities of permanent way and bridges steel construction workpiece is in outdoor work, running environment is complicated, is subjected to sunlight, sleet and various
The effect of corrosive substance, its metal parts easily corrodes.Corrosion is one of main damage form of hardware, it
Caused component failure is very huge with corresponding economic loss, according to incompletely statistics, during 1999 to 2000, iron
Annual more than 400,000,000 yuan of the correlative charges expenditure of road portion corrosion and protection." the five times of laws " proposed according to American scholar, if
Anticorrosion labourer is made in place, and substantial amounts of loss can be avoided or delayed.
In recent years, the anticorrosive paint used on railway facilities of permanent way and bridges steel construction workpiece mainly has zinc-rich coating, epoxy
Zinc rich primer, alcohol acid primer, phenolic aldehyde anti-corrosive primer, epoxy fat anti-corrosive primer, two component epoxy priming paint, epoxy polyurethane priming paint
Deng.But special industry and its special outdoor adverse circumstances due to railway, traditional coating is in salt spray resistance, adhesive force, weather-proof, resistance to
It is impossible to meet use requirement in the main performances such as mill, therefore, exploitation and searching are applicable railway facilities of permanent way and bridges steel construction workpiece
Anticorrosive paint is particularly significant urgent task.
The content of the invention
In view of the shortcomings of the prior art, present invention solves the technical problem that being for railway facilities of permanent way and bridges steel construction workpiece surface
Anti-corrosion provides a kind of zinc alkene anticorrosive paint of the excellent performance such as salt spray resistance, adhesive force, weather-proof.
The present invention adopts the following technical scheme that to solve above-mentioned technical problem：
A kind of zinc alkene anticorrosive paint, by weight ratio composition be, modified epoxy 10-40%；Functional filler 20-50%；Zinc
Powder 0.01-28%, graphene 0.2-3%, surfactant 3-15%, dimethylbenzene 5-25%, n-butanol 5-25%, the weight of all components
It is 100% to measure sum.
It is further improved to be, the performance indications of described graphene, the number of plies≤30；Their unit conductance rate >=4000S/m；Than
Surface area BET is 90~250m2/g。
A kind of zinc alkene anticorrosive paint, it is characterised in that：It is included using step,
A. pre-process, before construction, workpiece surface to be coated is subjected to degreasing and rust removal, go to degrease, salinity and other dirts；Then
Brushed；
B. zinc alkene anticorrosive paint is made up of zinc alkene anti-corrosion primer and supporting curing agent bi-component, first by zinc alkene anti-corrosion when using
Priming paint stirs, then by zinc alkene anti-corrosion primer：Curing agent=10：1 ratio mixes two components, and stirs；It can add
Plus 0~15% content solvent or diluent；Then application is carried out again after waiting the curing of zinc alkene anticorrosive paint；
Curing time, 10 DEG C~30 min；20 DEG C~20 min；30 DEG C~10 min；
Surface drying time, 25 ~ 35min, temperature is 20 ~ 25 DEG C；
Dry-hard time, 11 ~ 13h, temperature is 20 ~ 25 DEG C；
Most short interval between coating, when temperature is 8 ~ 10 DEG C, 15 ~ 16h；When temperature is 20 ~ 25 DEG C, 10 ~ 12h；Temperature is 35 ~ 40 DEG C
When, 6 ~ 8h；
When c. constructing, workpiece surface temperature must be higher than dew-point temperature more than 3 DEG C, and less than 50 DEG C；Environment when brushing operation
Relative humidity is less than 85%；It should be stirred continuously when brushing operation, prevent precipitation；
D. application can be using spraying or brushing method, and priming paint film layer gross thickness is 60~80um, and point twice are brushed；Can after doing solid work
Coating finish is carried out in its film surface.
A kind of new application of zinc alkene anticorrosive paint, described zinc alkene anticorrosive paint is used for railway facilities of permanent way and bridges steel construction workpiece
In anticorrosion.
The present invention has the advantages that compared with prior art：
（1）Because the anticorrosion mechanism of coating used in the present invention is the good electric conductivity of graphene and the overlap joint characteristic of zinc flake,
Good conductive laminated network structure is so formd in coating surface, corrosive medium immersion is hindered, with good physics screen
Effect is covered, steel construction workpiece is effectively protected and improves the corrosion resistance on its surface.In addition, replacing part zinc using graphene
Powder, coating not only still there is excellent cathodic protection to act on, and zinc powder consumption is reduced in dope preparing process, is reduced in the later stage
Harm and pollution of the zinc fume to human body and environment in welding processing.
（2）Application is carried out to railway facilities of permanent way and bridges steel construction Workpiece structure workpiece using the present invention, it carried out after doing solid work
Salt spray resistance, the test of adhesive force main performance.A. resistance to neutral salt spray test can reach more than 3000 hours, largely exceed
Existing zinc rich primer professional standard I requirements（It is 600h）；B. adhesive force test is up to 12-21MPa, much larger than the universal standard
（≥6 MPa）.
（3）Because zinc powder consumption greatly reduces in coating components used in the present invention, thus its volume solid content apparently higher than
Traditional zinc rich primer.Under the conditions of identical quality solid content, the volume solid content of coating is about the 1.6 of traditional zinc rich primer
Times, in other words, in identical coating layer thickness, its amount ratio tradition zinc rich primer saves more than 30%.
Zinc alkene anticorrosive paint post coat technique provided by the present invention is simple, can be used for different purposes, not of the same race
The anticorrosive paint of the railway facilities of permanent way and bridges steel construction workpiece of class and shape.
