Abstract
The utility model relates to an anti-corrosion structure, in particular to a composite anti-corrosion structure of a buried pipe. The structure comprises an anti-rust paint layer, an inner anti-corrosion layer and an outer protective layer in sequence from inside to outside, wherein the inner anti-corrosion layer comprises a rusted epoxy primer layer and a polyurethane finishing coat layer in sequence from inside to outside, the outer protective layer comprises at least two bituminous epoxy paint layers, and a glass wool cloth belt layer is arranged between every two adjacent bituminous epoxy paint layers. According to the composite anti-corrosion structure of the buried pipe, the anti-corrosion layer is protected from corrosion through the outer protective structure; furthermore, due to the fact that the anti-corrosion layer is of a multi-layer composite structure, the pipe can be protected from rustiness and outside corrosion, and the service life of the buried pipe is prolonged.
Description
Technical field
The utility model relates to a kind of anticorrosion structure, is specially underground pipe composite anti-corrosive structure.
Background technique
The anticorrosive coat of underground pipe is generally smears corrosion resistant coating, and this simple protection against corrosion is simple in structure, and effect cannot not continue longly, affects the working life of underground pipe.
Model utility content
Underground pipe composite anti-corrosive structure, comprises rust preventive coating, anticorrosion internal layer, protection skin from inside to outside successively, and described anticorrosion internal layer comprises epoxidation zone rust prime coat, polyurethane finish layer from inside to outside successively; Described protection skin comprises at least two-layer bituminous epoxy enamelled coating, between described adjacent two layers bituminous epoxy enamelled coating, has glass fibre cloth belt.
Described protection skin comprises shellring oxygen pitch enamelled coating and layer glass silk cloth belt, and described layer glass silk cloth belt is clipped in respectively between adjacent two-layer bituminous epoxy enamelled coating.
The underground pipe composite anti-corrosive structure that the utility model provides, is difficult for suffering erosion by outer layer protection structural defence anticorrosive coat, and the multi-layer compound structure of anticorrosive coat own, can prevent pipeline rust and extraneous corrosion, has extended the working life of underground pipe.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Embodiment
Accompanying drawings embodiment of the present utility model, as shown in Figure 1, underground pipe composite anti-corrosive structure is wrapped in outer sleeve 100 outer walls, and underground pipe composite anti-corrosive structure comprises rust preventive coating 1, anticorrosion internal layer, protection skin from inside to outside successively;
Anticorrosion internal layer comprises epoxidation zone rust prime coat 2, polyurethane finish layer 3 from inside to outside successively; Wherein epoxidation zone rust prime coat 2 is three-decker, smears the epoxy primer for rusted steel of three times, and polyurethane finish layer 3 is double-layer structure, smears the polyurethane finish of twice.
Protection skin is followed successively by bituminous epoxy enamelled coating 4, glass fibre cloth belt 5, outermost surface bituminous epoxy enamelled coating 6 from inside to outside, and wherein outermost surface bituminous epoxy enamelled coating 6 is double-layer structure, smears two-layer bituminous epoxy paint.
As optimizing embodiment, comprise two groups of bituminous epoxy enamelled coatings 4, glass fibre cloth belt 5, protect skin and be followed successively by from inside to outside bituminous epoxy enamelled coating, glass fibre cloth belt, bituminous epoxy enamelled coating, glass fibre cloth belt, outermost surface bituminous epoxy enamelled coating.
