Abstract
The utility model relates to a low-permeability fuel hose, which is characterized by mainly consisting of an impermeable layer, a partition layer, a middle adhesive layer, a reinforced layer and an external adhesive layer. The low-permeability fuel hose has the advantages that the fuel hose which adopts new processes and novel environment-friendly THV materials and utilizes low permeability of the materials can effectively stop gas from being permeated and volatilized, thereby resolving the permeated problem, increasing automobile integral emission index, realizing automobile Euro IV emission standard or approximating zero emission, and then protecting environments.
Description
Technical field
The utility model belongs to motor vehicle fittings, relates in particular to a kind of gas that can effectively stop and permeates volatilization, improves the low-penetration fuel flexible pipe of the whole emission index of automobile.
Background technique
At present, because the increase day by day of automobile demand, the continuous of car owning amount risen, and the pollution of motor vehicle emission has become the key factor of urban atmospheric pollution, more and more causes people's extensive concern.The fuel hose that now uses is four-layer structure, constitute by separation layer, mesoglea, reinforced layer and outer glue-line, though improving aspect structural design and the selection, but existing some problems,, anti-permeability difference poor as oil resistance and fuel oil type only are applicable to deficiencies such as unleaded gas.Especially incompatibility bio-fuel-oil, methyl alcohol, APPLICATION OF ETHANOL GASOLINE.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of low-penetration fuel flexible pipe is provided, and can effectively stop gas infiltration volatilization, has improved the whole emission index of automobile.
The utility model for achieving the above object, by the following technical solutions: a kind of low-penetration fuel flexible pipe is characterized in that: mainly be made of the impervious barrier, separation layer, mesoglea, reinforced layer and the outer glue-line that connect successively from inside to outside.
Described impervious barrier thickness is 〉=0.5mm; Separation layer thickness is 0.12-0.2mm; Mesoglea thickness is 〉=1mm; Reinforced layer thickness is 0.3-0.5mm; Outer bondline thickness is 〉=1mm.
The utility model beneficial effect: the low-penetration fuel flexible pipe improves from structure, material and technology, increased impervious barrier, increased oil resistance, be not only applicable to unleaded gas, but also be applicable to methyl alcohol, ethanol petrol and bio-fuel-oil, can satisfy more multizone weather conditions, Applicable scope is more extensive.Employing is adopted new technology and novel environment friendly THV material; utilize its hypotonicity, can effectively stop gas infiltration volatilization, solved the infiltration problem of fuel hose; improve the whole emission index of automobile, realized the Europe IV emission standard of automobile or near zero-emission: realized the effect of protection environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.
See accompanying drawing for details, a kind of low-penetration fuel flexible pipe mainly is made of the impervious barrier 1, separation layer 2, mesoglea 3, reinforced layer 4 and the outer glue-line 5 that connect successively from inside to outside.Described impervious barrier thickness is 〉=0.5mm; Separation layer thickness is 0.12-0.2mm; Mesoglea thickness is 〉=1mm; Reinforced layer thickness is 0.3-0.5mm; Outer bondline thickness is 〉=1mm.Flexible pipe adopts the composite pipe of THV ECD or THV nitrile butadiene rubber or THV resin system composite structure, can improve goods softness, corrosion resistance, osmotic-pressure-tolerant, flame retarding and sealing.Can make in the vehicle fuel flexible pipe and can eliminate static automatically.Adopt new technology and directly finish impervious barrier, separation layer, mesoglea, reinforced layer and outer glue-line and extrude synchronously, twine, coat, compound expressing technique disposal molding, the product structure conformity is strong.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
