Description
Technical field
The present invention relates to the oil transportation tubular construction comprising polymer composite, specifically a kind of antistatic oil transportation of resistance to fuel oil
Pipe.
Background technology
Conventional gasoline station is also easy to produce corrosion failure with metallic conduit, causes leaking gasoline, pollution environment and underground water.With
Continuous improvement to environmental requirement, it has been trend of the times that metallic oil pipeline is substituted by plastics oil pipeline.Plastic conduit system
System has more cleaning, it is safer, firmer, more convenient the characteristics of, its application in station construction is trend of the times, at present
Progressively deploy..In terms of existing plastic pipe manufacturer has focused largely on pipe material for water supply, targetedly oil-gas pipe material market is still
Immature, the especially resistance to antistatic oil pipeline technical research of fuel oil is relatively fewer.
Except this, fuel component is complicated, is mostly flammable liquid, resistivity is all higher.Fuel oil flows in plastic conduit
When, oil body and pipe friction, it is easy to produce and accumulation electrostatic.Tube wall is more coarse, and fuel flow rate is faster, and the electrostatic of generation is also got over
Many, when liquid leaves the mouth of pipe, will discharge generation electric spark, cause the vapor ignition of flammable liquid to burn.Therefore, petroleum pipeline
There is anti-static function to be the key for solving this potential safety hazard in road.
Therefore, during the popularization of plastics oil pipeline and use, it would be highly desirable to which the key issue of solution is exactly to develop simultaneously
Have the plastics oil pipeline material of antistatic and resistance to fuel characteristic concurrently.Also require that material has good mechanics and anti-aging simultaneously
Basic performance needed for the engineer applieds such as performance.
The plastics oil pipeline at present with resistance to fuel oil and anti-static function is generally five-layer structure, is followed successively by adds from outside to inside
Strong layer, tack coat, resistance to oil reservoir, tack coat and antistatic layer.The anlistatig tubing of resistance to fuel oil of three-decker also has been reported that
(201220320377)：Superficial layer is by with antistatic, high-low temperature resistant, ageing-resistant performance good ethylene propylene diene rubber and terylene
Fabric is composited, and intermediate layer is combined for EPM and braided steel wire with anti-flaming function and is made, internal layer by
Nitrile rubber with good oil resistance is made.Because tubing is mostly extrusion forming, therefore this variety of functional layers are bonded
Structure together, requires higher to mould, and the intractability of pipe joint is big, and whole production process is complicated.
The content of the invention
The present invention to be solved technical problem and be to provide a kind of with resistance to fuel oil and anti-static function, and manufacturing process
Simply, the low antistatic petroleum pipeline of resistance to fuel oil of cost.
The antistatic petroleum pipeline of resistance to fuel oil of the present invention, includes one layer of oil resistant being made up of oil-resisting antistatic high polymer material
Antistatic body.
The oil-resisting antistatic body is wrapped with the back-up coat of the suitable high polymer material of one layer of intensity, back-up coat with it is resistance to
It is integrated between the antistatic body of oil by one layer of tack coat bonding.
The first scheme of the oil-resisting antistatic layer material composition is：Its composition by the matrix composition of resistance to fuel oil, it is conductive into
Divide, conductive compositions lapping is constituted；The matrix composition of resistance to fuel oil is ethylene-vinyl alcohol copolymer, polyether-ether-ketone, polyphenylene sulfide

It is preferred that, by ratio of weight and the number of copies, the resistance to fuel oil material matrix composition account for 70~80 parts, conductive compositions account for gross mass
20~30 parts, conductive compositions lapping account for 5~10 parts of gross mass.
It is preferred that, by ratio of weight and the number of copies, in the resistance to fuel oil material matrix composition, ethylene-vinyl alcohol copolymer 50~80
Part, 10~30 parts of polyether-ether-ketone, 2~20 parts of polyphenylene sulfide, 1~10 part of polytetrafluoroethylene (PTFE).
The second scheme of the oil-resisting antistatic layer material composition is：Its composition by the matrix composition of resistance to fuel oil and it is conductive into
It is grouped into；The matrix composition of resistance to fuel oil is in ethylene-vinyl alcohol copolymer, polyether-ether-ketone, polyphenylene sulfide, polytetrafluoroethylene (PTFE)
One or more combination；The conductive material is permanent type intrinsic conducting polymer；Between described matrix material, matrix material with
Between conductive material, interpenetrating polymer networks structure is respectively formed.
It is preferred that, the permanent intrinsic conducting polymer is polyaniline, polyacetylene, polythiophene, polypyrrole, polyhenylene, poly-
