Above-mentioned technical purpose of the present utility model technical scheme is that:One kind is used for steel construction
The anticorrosive composite coating of weld seam, the anticorrosive composite coating include the polypropylene fibre anti-corrosion glue-line coated on face of weld, institute
State and activated carbon xeraphium last layer is stained with polypropylene fibre anti-corrosion glue-line, phenolic aldehyde ring is coated with the activated carbon xeraphium last layer
Oxygen resin coating layer.
By using above-mentioned technical proposal, polypropylene fibre anti-corrosion glue-line realizes first of antiseptic effect to weld seam, it
Activated carbon xeraphium last layer is added afterwards, and reduction weld seam is moist, that is, reduces the wet corrosion phenomenon on weld seam, be eventually adding epoxy novolac
Resin coating layer, further strengthen the anticorrosive work to weld seam.
The utility model is further arranged to：Polyurethane resin is coated with the novolac epoxy resin dope layer
Coating.
By using above-mentioned technical proposal, polyurethane resin coating has good wearability, can strengthen weldering
The wearability of seam, extend the service life of weld seam.
The utility model is further arranged to：Mineral oil layer is coated with the polyurethane resin coating,
Ceramic filler coating is coated with the mineral oil layer.
By using above-mentioned technical proposal, addition mineral oil layer can be realized on polyurethane resin coating
Preferable water resistance, the wet corrosion of weld seam is reduce further, while ceramic filler coating can rise to mineral oil layer
To preferable protective effect, mineral oil layer is prevented to be worn.
The utility model is further arranged to：The ceramic filler coating surface is coated with dumb light enamelled coating.
By using above-mentioned technical proposal, because surface is very smooth after ceramic filler curing of coatings, in dumb light enamelled coating
Under effect, ceramic filler coating surface brightness can be improved, reduce the reflection of light.
In summary, the utility model has the advantages that：
1st, this composite coating has preferable damp proof corrosive nature；
2nd, this composite coating has preferable anti-wear performance；
3rd, this composite coating has preferable counnter attack optical property.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1：A kind of anticorrosive composite coating for Steel Structure Weld, as shown in figure 1, anticorrosive composite coating includes applying
The polypropylene fibre anti-corrosion glue-line 1 of face of weld is overlying on, layer of active carbon xeraphium is stained with polypropylene fibre anti-corrosion glue-line 1
Last layer 2, re-coating has novolac epoxy resin dope layer 3 in activated carbon xeraphium last layer 2 afterwards.
The thickness of polypropylene fibre anti-corrosion glue-line 1 is 30-50 μm, and specially 40 μm, the thickness of activated carbon xeraphium last layer 2 is
80-100 μm, specially 90 μm, the thickness of novolac epoxy resin dope layer 3 are 120-160 μm, specially 100 μm.
Polypropylene fibre anti-corrosion glue-line 1 realizes first of antiseptic effect to weld seam, and polypropylene anticorrosion adhesive tape is a kind of new
Pollution-free, non-hazardous the environmental friendly, anti-corrosive product of type, its base material is fibre structure, can be reasonably resistant to due to soil stress and
Caused creep rupture, being detected through degradation proves its corrosion-resistant life up to more than 50 years；Activated carbon dried powder is added afterwards
Layer 2, due to that there can be some welding cinder holes in weld seam, the corrosion of weld seam can be accelerated after being contacted with the moisture content in air, in activity
In the presence of charcoal xeraphium last layer 2, activated carbon dried powder can fill up cinder hole in weld seam, while have certain drying
Performance, both filled can weld seam, enhance the hardness of weld seam, while weld seam can be caused to be in more dry state, effectively drop
