Description
Technical field
The utility model relates to a kind of motor car engine fuel oil oil hose, particularly relates to a kind of high-barrier vehicle fuel pipe.
Background technique
In the last few years, the appearance of bio-fuel-oil made China greatly reduce the dependence of non-renewable fuel.The petroleum and natural gas dependence on import of the annual about 60%-70% of China, makes country more encourage the large-scale promotion application of biofuel.But existing fuel pipe, because its permeability problems is difficult to meet the emission request of Abgasgesetz to bio-fuel-oil.
At present extensive use mostly be individual layer polyamide pipeline road, as PA11 or PA12 (PA is commonly called as nylon) pipeline, due to individual layer pipeline long-term exposed easy embrittlement in air, anti-permeability performance that the more important thing is individual layer pipeline is poor, bio-fuel-oil easily sees through pipeline and evaporate in air, not only biofuel is caused to a large amount of wastes, but also air ambient is polluted.So just accelerate exploitation and the application of multilayer tubing technology in fuel transfer system.In Chinese utility model patent 201120256965.9, having adopted internal layer is nylon 9 T, skin is the double-deck fuel pipe of nylon 12, the volatilization that stops biofuel has been played to certain effect, but this pipeline toughness is not strong, anti-tear tensile strength is low, is easy to fracture and deform phenomenon in being subject to greater impact power.Once generation traffic accident, is easy to cause the leakage of fuel, and personal safety is caused to very large threat.
Model utility content
The technical problems to be solved in the utility model be to provide a kind of simple in structure, barrier property good, long service life, high-barrier vehicle fuel pipe that toughness is high.
A kind of high-barrier vehicle fuel of the utility model pipe, wherein, comprise ethylene-tetrafluoroethylene copolymer inner barrier layer, polyamide 9T middle part barrier layer and nylon 12 outer barrier layer, ethylene-tetrafluoroethylene copolymer inner barrier layer outer surface is provided with polyamide 9T middle part barrier layer, the outer surface of polyamide 9T middle part barrier layer is provided with nylon 12 outer barrier layer, and the thickness proportion of ethylene-tetrafluoroethylene copolymer inner barrier layer, polyamide 9T middle part barrier layer and nylon 12 outer barrier layer is 1:1:3.
A kind of high-barrier vehicle fuel of the utility model pipe, wherein said ethylene-tetrafluoroethylene copolymer inner barrier layer is tube-shaped structure.
A kind of high-barrier vehicle fuel of the utility model pipe, passes through composite joint between wherein said ethylene-tetrafluoroethylene copolymer inner barrier layer, polyamide 9T middle part barrier layer and nylon 12 outer barrier layer.
A kind of high-barrier vehicle fuel of the utility model pipe difference from prior art is: the utility model is simple in structure, barrier property good, long service life, toughness are high.The nylon 12 outer barrier layer adopting has the feature of wear-resistant, ageing-resistant, high temperature resistant, high insulation, has increased impact resistance and the wearability of fuel pipe, has greatly extended the working life of oil hose.Adopt polyamide 9T middle part barrier layer, polyamide 9T permeability is low, organic solvent resistance strong, good flame retardation effect, effectively reduces the permeability of biofuel, has reduced the volatile quantity of biofuel.Adopt ethylene-tetrafluoroethylene copolymer inner barrier layer, not only further strengthen the barrier property of fuel pipe to biofuel infiltration, and ethylene-tetrafluoroethylene copolymer has good electrical insulation capability, effectively prevent that fuel pipe inside from having produced electrical spark because of friction.The more important thing is the toughness that has strengthened fuel pipe, the degree of resistance to tearing of fuel pipe and impact resistance are improved greatly, ensured other people personal safety.Between each layer, the distribution of thickness proportion makes barriering effect reach best.
Below in conjunction with accompanying drawing, a kind of high-barrier vehicle fuel pipe of the present utility model is described further.
Brief description of the drawings
Fig. 1 is the structural drawing of a kind of high-barrier vehicle fuel of the utility model pipe;
Fig. 2 is the view in transverse section of a kind of high-barrier vehicle fuel of the utility model pipe.
Embodiment
As shown in Figure 1 and Figure 2, for a kind of high-barrier vehicle fuel of the utility model pipe, comprise ethylene-tetrafluoroethylene copolymer inner barrier layer 1, polyamide 9T middle part barrier layer 2 and nylon 12 outer barrier layer 3.Ethylene-tetrafluoroethylene copolymer inner barrier layer 1 is tube-shaped structure, ethylene-tetrafluoroethylene copolymer inner barrier layer 1 outer surface is provided with polyamide 9T middle part barrier layer 2, and the outer surface of polyamide 9T middle part barrier layer 2 is provided with nylon 12 outer barrier layer 3.Polyamide 9T middle part barrier layer 2 respectively with ethylene-tetrafluoroethylene copolymer inner barrier layer 1, nylon 12 outer barrier layer 3 composite joint, be complex as a whole in joint.The thickness proportion of ethylene-tetrafluoroethylene copolymer inner barrier layer 1, polyamide 9T middle part barrier layer 2 and nylon 12 outer barrier layer 3 is 1:1:3.
A kind of high-barrier vehicle fuel of the utility model pipe, feature wear-resistant, ageing-resistant, high temperature resistant, high insulation that the nylon 12 outer barrier layer 3 adopting has, increase impact resistance and the wearability of fuel pipe, greatly extended the working life of oil hose.Adopt polyamide 9T middle part barrier layer 2, polyamide 9T permeability is low, organic solvent resistance strong, good flame retardation effect, effectively reduces the permeability of biofuel, has reduced the volatile quantity of biofuel.Adopt ethylene-tetrafluoroethylene copolymer inner barrier layer 1, not only further strengthen the barrier property of fuel pipe to biofuel infiltration, and ethylene-tetrafluoroethylene copolymer has good electrical insulation capability, effectively prevent that fuel pipe inside from having produced electrical spark because of friction.The more important thing is the toughness that has strengthened fuel pipe, the degree of resistance to tearing of fuel pipe and impact resistance are improved greatly, ensured other people personal safety.Between each layer, the distribution of thickness proportion makes barriering effect reach best.The utility model is simple in structure, barrier property good, long service life, toughness are high, compared with prior art has obvious advantage.
Above-described embodiment is described preferred implementation of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
