Abstract
A vehicle fuel hose resistant to high pressure and low in permeability is sequentially composed of a chloroprene rubber layer, a framework material layer, a chlorinated polyethylene rubber layer and a composite coating. The framework material layer is made of polyester fibers and steel wires. The composite coating is made of triisobutyl aluminum, vinyl silicone oil, polyimide, bentonite and silicon dioxide particles. The raw material of the composite coating is composed of, by weight, the triisobutyl aluminum of 5-10 parts, the vinyl silicone oil of 3-6 parts, the polyimide of 1-4 parts, the bentonite of 3-5 parts and the silicon dioxide particles of 8-15 parts. According to the hose, the framework material layer effectively improves the flexibility and the torsion resistance of the vehicle fuel hose, and the hose can be restored in shape after being subjected to high pressure; the granularity of the nano-meter silicon dioxide particles is basically uniform, so that the hose is low in permeability to liquid. Thus, the vehicle fuel hose can be widely applied to the vehicle field and has high practical value and economic value.
Description
Technical field
The present invention relates to rubber product technical field, particularly relate to a kind of high pressure resistant hyposmosis rubber tube of automobile fuel oil.
Background technique
The fast development of Domestic Automotive Industry brings development opportunity to automobile accessories product-sebific duct, if use 20m sebific duct to calculate by each automobile, 2005 are only newly-increased auto output to the demand of sebific duct just at 100,000,000 more than m, and add maintenance sebific duct, market potential is huge.Along with automobile is to future developments such as speed up, multifunction and travelling comfortes, and for making oil inflame completely and the use of the electric equipment such as electric injection device, turbo charging installation that uses or parts; In addition, be protection of the environment, automobile uses unleaded gas, and automobile engine nacelle narrows, and temperature rising etc. all propose higher requirement to automobile rubber pipe, and resistance to fuel oil, high temperature resistant, refrigerant permeability is low, the life-span is long etc. becomes the Developing mainstream of automobile rubber pipe.
Rubber tube of automobile fuel oil comprises fuel oil transport pipe and to the fuel pipe of motor supply fuel, is important safety member, also more to the performance requirement of its material.Hose lining will select the material of fuel-resistant medium and good heat resistance; Outer layer glue then will select heat-resisting, resistance to ozone, resistance to environmetal impact and the material good with the adhesion property of hose lining.Conventional fuel oil sebific duct uses the compound rubber pipe of hose lining/intermediate/outer layer glue three-decker, and internal layer is nitrile butadiene rubber; Skeleton is done with winding or braided fiber in mesosphere; Skin is neoprene, and for improving ageing-resistant performance, outer layer glue can use chlorosulfonated polyethylene rubber.In Europe, the sizing material that hose lining and outer layer glue all adopt ageing resistance and the good nitrile butadiene rubber of crack resistance and PVC＝polyvinyl chloride blended, but North America generally uses jet engine fuel, due to peroxidating gasoline can be produced, the blended rubber of nitrile butadiene rubber and PVC therefore can not be used.
When general-utility car travels, fuel hose serviceability temperature is 60 DEG C, and reach 120 DEG C when just stopping, therefore rubber tube of automobile fuel oil needs resistant to elevated temperatures performance.Along with the enhancing of people's environmental consciousness, and increasingly strict to automotive emissions restriction, people are also more and more higher to energy-conservation and safe requirement, also promote the development of automotive engineering thus, also improve further the usage requirement of rubber tube of automobile fuel oil.
At present, electronic fuel injection system motor is adopted to be one of important measures reducing discharge.After automobile adopts electronic fuel injection engine, fuel system pressure improves about 10 times than common motor, and the use of electronic fuel injection engine not only makes the temperature of motor itself raise, and the ambient temperature of surrounding is also raised; In addition with the addition of oxidized compound in used fuel component.High temperature, acidifying (sour gasoline) and high-pressure trend is shown as in oil-fired system, very harsh to the life requirement of sebific duct, thus propose and develop requirement that is high pressure resistant, low-penetration fuel hose.In addition motor is to high-power, high-revolving future development, causes the acute variation of sebific duct operating ambient temperature, impels the material of rubber tube of automobile fuel oil and processing method constantly developing and upgrading.
Summary of the invention
The object of the present invention is to provide the high pressure resistant hyposmosis rubber tube of automobile fuel oil of a kind of safety, energy-saving and environmental protection.
For realizing above-mentioned purpose of the present invention, the invention provides a kind of high pressure resistant hyposmosis rubber tube of automobile fuel oil, being followed successively by from the inside to the outside: neoprene layer, framework material layer, chlorinated polyethylene rubber layer and composite coating; Described framework material layer is made up of polyester fibre and steel wire; Described composite coating is made up of triisobutyl aluminium, vinyl silicone oil, polyimide, bentonite, silica dioxide granule.
The parts by weight of described composite coating raw material are: triisobutyl aluminium 5-10 part, vinyl silicone oil 3-6 part, polyimide 1-4 part, bentonite 3-5 part, silica dioxide granule 8-15 part.
Described neoprene is the synthetic rubber that main raw material carries out α-polymerization and produce by chlorobutadiene (i.e. 2-chloro-1,3-butadiene), and belong to crystallinity rubber, its pure glue has higher tensile strength, and elongation at break is large.Neoprene is produced with emulsion polymerization, and flow mostly is single still batchwise polymerization; Polymerization temperature controls at 40 ~ 60 DEG C, and conversion ratio is about 90%.
Described bentonite is the inorganic mineral gel refined by natural montmorillonite.
According to the chemical structure of repetitive, polyimide can be divided into aliphatic, semi-aromatic and aromatic polyimide three kinds; According to thermal property, thermoplasticity and Thermocurable polyimide can be divided into.
Compared with prior art beneficial effect of the present invention.
High pressure resistant hyposmosis rubber tube of automobile fuel oil provided by the invention, the framework material layer made by polyester fibre and steel wire, is effectively improved ductility, the antitorque knot ability of rubber tube of automobile fuel oil, and recovers deformation after keeping sebific duct to be subject to high pressure; Meanwhile, the nanometer silicon dioxide particle of interpolation has basic uniform granularity, makes sebific duct present hypotonicity to liquid.Therefore, this rubber tube of automobile fuel oil can be widely used in automotive field, has stronger use value and economic value.
