Abstract
The invention relates to a low-permeability fuel hose with a flexible fluorine material. An epichlorohydrin rubber layer and a frame layer are sequentially bonded on an innermost layer of the fuel hose with the existence of F-TPV, and an outermost layer is coated with epichlorohydrin rubber. The pore diameter of the fuel hose of a vehicle of the embodiment of the invention is specifically configured according to the requirements of various hoses of the vehicles. The F-TPV in the fuel hose is the innermost layer, compared with the traditional fluorine rubber fuel hose, the permeability resistance is better, and the permeability is reduced to 0-3g/100cm<2>/24h from the original 4-8g/100cm<2>/24h. Compared with the fluororesin fuel hose, the fuel hose achieves the same permeability resistance, the F-TPV is soft, and the permeability of the F-TPV is better when the hardness is the same with that of fluororesin. The permeability is better and better along with the increase of the thicknessof the F-TPV, thereby reflecting the characteristics of flexibility and low permeability of the fuel hose.
Description
Technical field
The present invention relates to fuel hose, particularly have the flexible fluorine material low-penetration fuel hose.
Background technique
Development along with automobile industry, the enhancing of environmental consciousness, original fuel hose performance can not satisfy the performance requirement that automobile makes rapid progress, present fuel hose structure generally uses fluorine rubber as internal portioning layer, this material has excellent oil resistance, heat-resisting quantity, ozone resistance, and the fuel oil permeability also there is extraordinary barrier property, uses the high fluorine rubber of fluorine content can satisfy the emission request of Europe III.German standard TL52424 is to be the fuel hose of internal layer with the fluorine rubber at present, and its infiltration capacity requirement is＜8g/100cm
2/ 24h, and As time goes on automobile industry has higher requirement or even zero infiltration to osmotic-pressure-tolerant, only uses fluorine rubber not reach requirement as internal layer.FTPV flexible fluorine material low-penetration fuel pipe is used at present existing people's research modification on the nitrile butadiene rubber layer, makes to have one deck FTPV flexible fluorine material construction layer in the composite structure at least.Though the osmotic-pressure-tolerant of the fuel hose of this structure can be very superior, make but need be based upon on the basis that comprises one deck modified butadiene acrylonitrile rubber layer, the structure narrow limitation of this fuel hose is too big, for satisfying higher, wideer usage requirement, just must there be a kind of novel fuel hose to satisfy the usage requirement of automobile.
Summary of the invention
Purpose of the present invention mainly is to improve the osmotic-pressure-tolerant of existing fuel hose, thereby improve Security, the feature of environmental protection, the energy saving of fuel hose, with the epichlorohydrin rubber is adhesive layer, (F-TPV is meant fluorine-containing Thermoplastic Vulcanizate (the English Thermoplastic Vulcanizate of being of Thermoplastic Vulcanizate and setting has F-TPV, abbreviate TPV as), also claim FTPV) at the fuel hose of internal layer.F-TPV compares with fluororesin (THV) fuel hose, reaches same osmotic-pressure-tolerant, and it is soft that F-TPV shows, and with fluororesin (THV) when hardness is identical, the permeability of F-TPV will be got well.Because F-TPV fluorine material contains fluorine atom and a kind of synthetic high polymer elastomer on the carbon atom of main chain or side chain, the electronegativity of fluorine atom is high, so have splendid fuel resistance.F-TPV has the very high carbon-fluorine bond of bond energy (C-F) simultaneously, make it have very high heat resistance so have the stability of height, and have excellent inorganic acid resistance and organic acid, halide, hydrocarbon, alcohols etc., thereby improve its osmotic-pressure-tolerant energy greatly.
The CO that motor vehicle emission goes out (carbon monoxide), HC+NOx (hydrocarbon and nitrogen oxide), PM harmful gases such as (particulate, soots), they all are the harmful gases that motor produces in burning work done process.The reason that these harmful gases produce is different, and CO is the incomplete intermediate product of fuel oil oxidation, can produce CO when oxygen is inadequate, and mixture strength reaches the inhomogeneous CO increase that all can make in the exhaust of mixed gas greatly.Reasons such as HC is a unburned material in the fuel, and is inhomogeneous owing to mixed gas, that chamber wall is cold cause the part fuel oil not have enough time to burn and just are discharged away.NOx is a kind of material that fuel (gasoline) produces in combustion process.A kind of material that anoxic produced when PM also was oil inflame.In order to suppress the generation of these harmful gases, impel automobile production producer to improve product to reduce the source of generation of these harmful gases.So use the F-TPV material particularly important,, be the good material of making the fuel hose barrier layer because osmotic-pressure-tolerant can be splendid with regard to what show.
Through our repeatedly research, make F-TPV by with the epichlorohydrin rubber co-extrusion, can well bond together, in use composite bed the delamination segregation phenomenon can not occur.Consider the load performance of F-TPV fuel hose, the framework layer of layer configuration therein, as: AR (aramid fibre), PES (polyester fibre), cotton thread etc.
Technological scheme of the present invention is as follows:
Have the flexible fluorine material low-penetration fuel hose, F-TPV is present in the innermost layer of fuel hose, is bonded with the epichlorohydrin rubber layer successively, framework layer, and outermost surface coats epichlorohydrin rubber.
