The product oil pipeline with the efficient static conductive lining comprises a pipeline and a lining, wherein the lining is attached to the inner wall of the lining. The lining is a three tight connection layer composite structure. A static conductive resin layer, a texture enhancement layer, and a seepage-proofing film are fixed on the inner wall of the lining from inside to outside sequentially. The static conductive resin layer is made of mica modified carbon nanotubes reinforced resins with the static conductive function. The texture enhancement layer is made of thermoplastic polyurethane (TPU) polyamide fabrics and the mica modified carbon nanotubes reinforced resins are soaked and coated on the texture enhancement layer. The seepage-proofing film is made of thermoplastic polyurethane elastomers.

Description
Technical field
The utility model belongs to the pipework field, and specifically a kind of have a processed oil pipeline of efficiently leading the static liner, is mainly used in processed oil pipeline system and chemical engineering piping systems etc.
Background technique
Epoxy resin not only has closely knit, anti-water, good, the intensity high of anti-leakage as anticorrosive, has simultaneously the good manufacturabilities such as strong adhesion, normal-temperature operation, shaping performance excellence, easy construction, and moderate.Be present widely used a kind of material in non-excavation pipeline rehabilitation technique, can use in the engineering in the fields such as reparation of modern city plumbing, crude oil pipeline etc.
But along with the development of Trenchless Technology for Pipe Rehabilitation, the inner lining material that is applied to the processed oil pipeline reparation requires more and more higher to the electrostatic conductive performance of himself.Take jet fuel as example, require under many circumstances to be filled into oil product conductivity on the aircraft at 50～450pS/m by pipeline, and epoxy resin itself is a kind of good high dielectric property that has, anti-surface leakage, the superior isolation material of anti-electric arc, after with it old product pipeline being repaired, the oil product flow velocity increases, interior friction increases, compare with original steel pipeline, existing liner repair layer is easy to cause electrostatic accumulation and can't be dissipated in the surrounding environment, make the conductivity that is filled into the oil product on the aircraft defective, bring serious hidden danger for the flight safety of aircraft.
At present, the method of general raising epoxide resin material electrostatic conductive performance is to add the conductive materials such as carbon black, iron powder in material, but this method is subjected to the restriction of conductive filler self performance very large, but also can make the Material Physics mechanical property after the curing can not be up to standard, does not have feasibility.What also be not specifically designed in the world at present processed oil pipeline reparation usefulness leads the electrostatic type liner.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of processed oil pipeline of efficiently leading the static liner that has is provided, and on the basis that guarantees physical and mechanical properties, improves the electrostatic conductive performance of processed oil pipeline liner.
The utility model is realized with following technological scheme: a kind of have a processed oil pipeline of efficiently leading the static liner, comprise pipeline and be attached on the inner-walls of duct liner, described liner is three-layer composite structure, three layers are closely linked, are successively from inside to outside: be cemented in and lead static resin layer, fabric enhancement layer and antiseepage rete on the inner-walls of duct.
The described static resin layer of leading is that the mica modified carbon nano-tube of leading electrostatic function that has that solidifies strengthens resin.
Described fabric enhancement layer is TPU-nylon fibre fabric, and soaking Tianjin on it has the mica modified carbon nano-tube to strengthen resin.
Described antiseepage rete is TPUE, and soaking Tianjin on it has the mica modified carbon nano-tube to strengthen resin.
The beneficial effects of the utility model are: compare with existing processed oil pipeline, its liner has good physical and mechanical properties, corrosion resistance, ageing resistance, has simultaneously good electrostatic conductive performance, can effectively reduce the electrostatic accumulation phenomenon that causes because of friction in material and the oil product, assurance is filled into the requirement that product oil conductivity on the aircraft meets NBS, guarantees flight safety.Also can be used for other occasions strict to electrostatic conductive performance such as industrial chemicals conveying, purposes is comparatively extensive.
