Abstract
The utility model discloses an automobile rubber oil tube with low fuel oil permeability. An inner layer is made of nitrile butadiene rubber; a layer of thin THV (Tetrafluoroethylene) film is sandwiched in the middle of the nitrile butadiene rubber; the film has a high prevention property for permeability of fuel oil; an aramid fiber enhancement layer is woven outside the nitrile butadiene rubber so as to improve the pressure resistance and the fatigue resistance of a rubber hose; chlorosulfonated polyethylene with smell of rubber at the outer layer is adhered to the nitrile butadiene rubber at the inner layer under the function of infrared heating, so that a whole product is good in weather resistance. Practical application is met, and a good way for preventing fuel oil permeation is provided for rubber tubes to meet the increasingly improved automobile emission requirements.
Description
Technical field
The utility model relates to a kind of rubber hose of the hypotonicity for automobile, particularly has the rubber fuel pipe of THV hyposmosis film.
Background technique
Each automobile has the fluids such as Oil, Water, Gas to carry, and need to connect by flexible rubber hose.Along with developing rapidly of automotive industry, a large amount of motor vehicle emissions brings more and more serious pollution to our environment, and these pollutions are not only the exhaust emissions of automobile, because the material adopting for the pipeline rubber hose of fuel delivery in current automobile is nitrile butadiene rubber, it is internal layer, interposition cellulose ester enhancement layer and outer field chlorosulfonated polyethylene form, this structure is poor to the permeability protection of fuel oil, fuel oil can be discharged in atmosphere by tube wall infiltration gradually, in the air that fuel oil does not discharge through motor, cause pollution of atmosphere.And the pollution that cause poor to the protection of fuel oil infiltration for wherein to have suitable part be rubber hose, in the face of more and more stricter emission standard, requires the impermeable proposition requirements at the higher level that we must be to rubber hose.
Model utility content
The utility model provides a kind of automobile rubber oil hose of fuel oil hypotonicity, can reach the strictest emission request at present completely.
The technical solution of the utility model is as follows:
A kind of automobile rubber oil hose of fuel oil hypotonicity, be respectively from inside to outside interior nitrile butadiene rubber layer, hyposmosis thin layer, outer nitrile butadiene rubber layer, cellulose ester enhancement layer and chlorosulfonated polyethylene layer, described hyposmosis thin layer is to be bonded in the middle of interior nitrile butadiene rubber layer, outer nitrile butadiene rubber layer.
The thickness of described interior nitrile butadiene rubber layer, hyposmosis thin layer, outer nitrile butadiene rubber layer, cellulose ester enhancement layer and chlorosulfonated polyethylene layer is 1.2mm, 0.1mm, 0.8mm, 0.4mm, 1.5 mm.
The THV rubber hose of this hyposmosis is to adopt the good nitrile butadiene rubber (NBR) of fuel resistance energy as inside liner, fuel resistance can cover on inside liner as mesosphere by good THV film, outside is at coated nitrile butadiene rubber and cellulose ester enhancement layer (AR or PET), chlorosulfonated polyethylene (CSM) in the coated good weatherability of skin, the wall thickness of internal layer nitrile butadiene rubber is in 1.2mm left and right, the thickness of THV thin layer is at 0.1mmmm, for avoiding product curved part fold when vulcanizing, aspect cost-saving, consider simultaneously, the wall thickness of THV thin layer is difficult for surpassing 0.15mm, the internal diameter of rubber hose can be from 5mm to 45mm, total wall thickness of product is at 3.5mm ~ 4.5mm.The nitrile butadiene rubber of THV film and internal and external layer is that the tackiness agent by adding in sizing material is bonding, and the bonding of nitrile butadiene rubber and outer field chlorosulfonated polyethylene is difficult to reach good bonding strength because centre also has one deck braided wire, need in two kinds of rubber, add tackiness agent, when pipe is extruded again by infrared heating be used for promote it bonding, reach not need to be when pipe be extruded spraying binder can solve the adhesion problem of inside and outside glue-line.
Accompanying drawing explanation
Fig. 1 is the utility model structural drawing.
Embodiment
Referring to accompanying drawing, a kind of automobile rubber oil hose of fuel oil hypotonicity, be respectively from inside to outside interior nitrile butadiene rubber layer 1, hyposmosis thin layer 2, outer nitrile butadiene rubber layer 3, cellulose ester enhancement layer 4 and chlorosulfonated polyethylene layer 5, hyposmosis thin layer 2 is to be bonded in the middle of interior nitrile butadiene rubber layer 1, outer nitrile butadiene rubber layer 3, and the thickness of interior nitrile butadiene rubber layer, hyposmosis thin layer, outer nitrile butadiene rubber layer, cellulose ester enhancement layer and chlorosulfonated polyethylene layer is 1.2mm, 0.1mm, 0.8mm, 0.4mm, 1.5 mm.
Hose lining is that wall thickness is the nitrile butadiene rubber (NBR) of 1.2mm left and right oil resistant, mesosphere is that wall thickness is the THV hyposmosis film of 0.1mm left and right, fuel oil is had to extremely strong impermeable left and right, THV thin layer covers outward after the nitrile butadiene rubber of about 0.8mm at its surface weave aramid fiber enhancement layer (AR), this braid plays conclusive effect to the resistance to pressure of rubber hose and fatigue resistance, finally extrudes chlorosulfonated polyethylene (CSM) rubber again.
Claims (2)
1. the automobile rubber oil hose of a fuel oil hypotonicity, it is characterized in that, be respectively from inside to outside interior nitrile butadiene rubber layer, hyposmosis thin layer, outer nitrile butadiene rubber layer, cellulose ester enhancement layer and chlorosulfonated polyethylene layer, described hyposmosis thin layer is to be bonded in the middle of interior nitrile butadiene rubber layer, outer nitrile butadiene rubber layer.
2. the automobile rubber oil hose of fuel oil hypotonicity according to claim 1, it is characterized in that, the thickness of described interior nitrile butadiene rubber layer, hyposmosis thin layer, outer nitrile butadiene rubber layer, cellulose ester enhancement layer and chlorosulfonated polyethylene layer is 1.2mm, 0.1mm, 0.8mm, 0.4mm, 1.5 mm.
