Abstract
The invention provides a rubber oil-resistant pipe which comprises inner rubber (1), a reinforcing layer (2) and outer rubber (3). The invention further provides a preparation method and an oil-resistant evaluation method for the rubber oil-resistant pipe. The rubber oil-resistant pipe is used in an automobile and has the advantages of excellent oil-resistant effect and simplicity and convenience in production.
Description
Technical field
The present invention relates to auto industry field, particularly a kind of rubber oil resistant pipe.
Background technique
In recent years, along with the develop rapidly of automobile industry, when bringing business opportunity to the automaker, compete also more and more fierce.Therefore, the quality of each vehicle manufacturer integral body has had higher requirement, and this is comprising rubber tube of automobile fuel oil.Traditional oil-resisting rubber hose is made of outer glue neoprene and interior glue nitrile butadiene rubber, but its oil resistance is not excellent especially, and particularly under the high temperature condition, the performance of anti-deteriorated gasoline is poorer, directly affects the total quality of automobile.
Summary of the invention
The present invention proposes a kind of rubber oil resistant pipe, has solved the leakage problem of vehicle fuel pipe in the prior art.
Technological scheme of the present invention is achieved in that rubber oil resistant pipe, contains following material and consists of:
Interior glue fluorine rubber
Outer glue epichlorohydrin rubber
Reinforced layer aramid fibre braided wire
Preparation method of the present invention finishes by rubber mixing mill and extruder.
The present invention extrudes a kind of rubber oil resistant pipe by adopting suitable interior glue, reinforced layer, outer glue.
The invention has the beneficial effects as follows:
(1) the present invention has obtained a kind of rubber oil resistant pipe, improves oil resistant and the resistance to heat of vehicle fuel pipe.
(2) the present invention has obtained a kind of rubber oil resistant pipe, the leak-down rate of reduce fuel oil pipe, the total quality of raising automobile.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Figure 1 shows that half planing surface figure of rubber oil resistant pipe new structure.
Embodiment
The present invention by adopting suitable interior glue, reinforced layer, outer glue, extrudes a kind of rubber oil resistant pipe through extensive and deep research, carries out the oil resistant evaluation in high-temperature high-pressure reaction kettle, thereby finishes the present invention.Fig. 1 is half planing surface figure of rubber oil resistant pipe new structure of the present invention, outer glue 10: the elastomeric compound that adopts epoxychloropropane and ethylene oxide copolymerization to form; Reinforced layer 20: adopt the aramid fibre braided wire; Interior glue 30: adopt the F2463 fluororubber compounded rubber.
In the actual production process, at first interior glue and outer glue are carried out mixingly in mill, place and prepare to extrude with extruder after 24 hours.At first, extrude interior glue, twine the aramid fibre braided wire on interior glue surface simultaneously, after the shower that fills rubber paste, begin to extrude outer glue, finish the production of rubber oil resistant pipe.
Fluorine rubber
(English name: Fluororubber) main Types has three kinds to fluorine rubber: fluorine carbon, fluorine silicon and fluoroalkyl phosphonitrile.Main production is fluorine carbon at present, and the fluorine carbon fluorine rubber mainly comprises: vinylidene and chlorotrifluoroethylene (23 glue); The copolymer of vinylidene, hexafluoropropene (26 glue); The terpolymer of vinylidene, hexafluoropropene and tetrafluoroethylene (246 glue); Tetrafluoroethylene and propylene (4 third fluorine rubber).
In order to reach oil resistance of the present invention, the present invention has adopted the F2463 fluororubber compounded rubber.
The aramid fibre braided wire
The aramid fiber full name is " PPTA ", English is Aramid fiber (commodity of E.I.Du Pont Company are called Kevlar), be a kind of novel high-tech synthetic fiber, have superhigh strength, high-modulus and high temperature resistant, acid-fast alkali-proof, the premium properties such as lightweight, its intensity is 5～6 times of steel wire, modulus is steel wire or glass fibre 2～3 times, toughness is 2 times of steel wire, and weight only is about 1/5 of steel wire, under the temperature of 560 degree, do not decompose, do not melt.It has good insulating properties and aging quality resistance, has very long life cycle.
Epichlorohydrin rubber
Epichlorohydrin rubber (epichloro-hydrin rubber) means the polyether-type rubber that contains chlorine on the side group.It is the macromolecular elastomer that is formed by the cyclic ether ring-opening polymerisation that contains epoxy group.Rubber is divided into two kinds of homopolymer and copolymers according to the difference of polymerization methods.The former is polymerized separately by epoxychloropropane; The latter is formed by epoxychloropropane and ethylene oxide copolymerization.
In order to reach weather resisteant energy of the present invention, the elastomeric compound that the present invention has adopted epoxychloropropane and ethylene oxide copolymerization to form.
Below in conjunction with specific embodiment, further set forth the present invention.The experimental technique of unreceipted actual conditions in the following example is measured according to NBS usually.If there is not corresponding NBS, then carry out according to general international standard, normal condition or according to the condition that manufacturer advises.
Unless otherwise defined or explanation, the meaning that all specialties used herein are familiar with scientific words and those skilled in the art is identical.Any method similar or impartial to described content and material all can be applicable in the inventive method in addition.
Oil resistant test process: rubber pipe is dipped in the High Temperature High Pressure hydro-thermal reaction still that fills 93# gasoline, 160 ℃ of lower 24h that soak in the DHG-9075A electric heating constant-temperature blowing drying box take out test its weight, volume, hardness, carry out tensile strength and elongation at break experiment and observe its erosion profile.Find that by contrast the rubber pipe surface is still very smooth, volumetric expansion is little, and weight increases little, and mechanical properties decrease is not obvious.
The above only is preferred embodiment of the present invention, and is in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (4)
