An ultralow expansion brake rubber hose is characterized in that the hose comprises an inner rubber tube, a first reinforcing layer, a second reinforcing layer, and an outer rubber tube, a thermosetting resin which is set at the vulcanizing temperature is penetrated through reinforcing fibers constituting the first layer and cured by vulcanization, and thereby the first layer is made an integral cured layer. Therefore, the slippage between the reinforcing fibers of the first layer is prevented because the first layer is thus a cured layer, providing a brake hose low in expansion and excellent in durability. Such a brake hose is produced by a method comprising the step of forming a first reinforcing layer on the inner rubber tube by stranding, the stap of penetrating a thermally curing resin liquid through reinforcing fibers constituting the first reinforcing layer by soaking the first reinforcing layer in the thermosetting resin liquid of low viscosity, the step of forming a second reinforcing layer by stranding, and the step of extrusion-molding an outer rubber tube on the second reinforcing layer.
Description
Technical field
The present invention relates to be used for the brake rubber hose of brake device for car, specifically, ultralow expansion brake rubber hose that the swell increment when relating to initial pressure is minimum and manufacture method thereof.
Background technique
In the hydraulic brake system of automobile, the legpower of brake petal is transformed to hydraulic pressure, passes to each wheel cylinder by brake rubber hose by master cylinder.Brake rubber hose before is made of the reinforced layer of rubber pipe and braiding.Fig. 3 is the stereogram with the brake rubber hose biopsy cavity marker devices.Brake rubber hose is made of interior rubber pipe the 1, the 1st reinforced layer 2, intermediate rubber layer the 3, the 2nd reinforced layer 4 and outer rubber pipe 5.Interior rubber pipe 1 is by propylene diene rubber (EPDM), the styrene butadiene rubbers formations such as (SBR) of resistance to braking fluid.The 1st reinforced layer 2 is that the vinylon line braiding as reinforcing line is formed.Intermediate rubber layer 3 is by natural rubber (NR), EPDM, butyl rubber formations such as (IIR).The 2nd reinforced layer 4 forms the vinylon line braiding.Outer rubber pipe 5 is made of EPDM, neoprene (CR).
The manufacture method of above-mentioned brake rubber hose is as follows.First rubber pipe 1 in the periphery extrusion moulding of preprepared strip resin axle weaves the 1st reinforced layer 2 at the outer surface of interior rubber pipe 1.Then, on the outer circumferential face of the 1st reinforced layer 2, form intermediate rubber layer 3 with extrusion press extrusion moulding intermediate rubber layer 3 or coiling strip rubber tape.During coiling strip rubber tape, while the rubber tape of reeling weaves the 2nd reinforced layer 4 in the above.Then, extrusion moulding outer rubber pipe 5 on the periphery of the 2nd reinforced layer 4.These rubber hose are vulcanized with the strip axle, after the sulfuration, utilized hydraulic pressure to extract the strip axle, then, the strip rubber hose is cut into predetermined length use.
In recent years, along with the progress of engine technology and the improvement of road environment, the vehicle speed up is higher, stricter to the requirement of braking ability.Especially stopping power and braking sense there is higher requirement.Act among the pressure range of brake rubber hose, relevant with the braking sense is the low pressure range of 0～2.94MPa.Even under this low pressure, the reason that causes the flexible pipe internal volume to expand in hose construction, is not the elastic elongation because of the fiber of fabric reinforcement itself, but skid mutually between the reinforcing fibre that weaves or weave lax bigger influence arranged.
The factor that the domination internal volume expands is the 1st reinforced layer 2.For this reason, in order to suppress skidding between braided fiber, the reinforcing fibre (vinylon) on rubber pipe 1 outer circumferential face in being woven in is adhesively fixed before with binder.
But there is following problem in the method in binder reinforcing fibre being adhesively fixed on the rubber pipe outer circumferential face.That is, as binder, normally adopting rubber is solution-type sulfuration binder.At rubber is in the solution-type sulfuration binder, owing to contain solvent, so, after being coated on the interior rubber pipe 1, must need the certain hour drying, therefore, having applied rubber on the interior rubber pipe 1 is after solution-type vulcanizes binder, can not weave the 1st reinforced layer 2 immediately, so, can not carry out manufacturing process continuously.
In addition, in this method, though interior rubber pipe and reinforcing fibre are bonding, between the reinforcing fibre not necessarily by bonding.Therefore, the reinforcing fibre of the 1st reinforced layer 2 under the state bonding with interior rubber pipe 1 with the interior rubber pipe changing of the relative positions, can not suppress skidding mutually between the reinforcing fibre of the 1st reinforced layer 2 fully.So only the reinforcing fibre with the 1st reinforced layer 2 is bonded on the interior rubber pipe, can not get the little brake rubber hose of swell increment.
Goal of the invention
The present invention makes in view of the above problems, and its purpose is to provide a kind of brake rubber hose and manufacture method thereof of skidding mutually between the reinforcing fibre of the 1st reinforced layer of suppressing fully.
Another object of the present invention is by skidding mutually between the reinforcing fibre that suppresses the 1st reinforced layer fully, to provide ultralow expansion brake rubber hose and manufacture method thereof.
The summary of the invention summary
Technological scheme
To achieve these goals, adopt following solution.
Ultralow expansion brake rubber hose of the present invention, it is characterized in that, constitute by interior rubber pipe, the 1st reinforced layer, the 2nd reinforced layer, outer rubber pipe, form the reinforcing fibre of the 1st reinforced layer, the reinforcing fibre of the thermosetting resin that hardens has been soaked in employing under sulfurize temperature, make its sclerosis, the hardened layer that the 1st reinforced layer is formed as one by sulfuration.
Rubber pipe in above-mentioned can adopt the EPDM that is not easy to see through brake fluid, and the outer rubber pipe can adopt EPDM similarly.The reinforcing fibre that forms the 1st reinforced layer and the 2nd reinforced layer can adopt the vinylon silk.Thermosetting resin with reinforcing fibre soaks into can adopt melamine resin or phenolic resin.
The manufacture method of above-mentioned ultralow expansion brake rubber hose is characterized in that, carries out following the 1st to the 4th operation continuously;
In the 1st operation, braiding the 1st reinforced layer on interior rubber pipe;
In the 2nd operation, be impregnated in the low viscosity thermosetting resin liquid of reinforcing fibre of above-mentioned the 1st reinforced layer of saturable formation, thermosetting resin liquid is soaked in reinforcing fibre;
In the 3rd operation, weave the 2nd reinforced layer;
In the 4th operation, extrusion moulding outer rubber pipe on the outside of the 2nd reinforced layer.
In above-mentioned operation of soaking into thermosetting resin liquid, saturable low viscosity thermosetting resin liquid bath in reinforcing fibre is set, by being immersed in forcibly in the above-mentioned resin liquid bath, thermosetting resin liquid is soaked in reinforcing fibre.
In addition, preferably then in the operation of extrusion moulding outer rubber pipe, carry out making the operation of interior rubber pipe, thermosetting resin, the sclerosis of outer rubber pipe continuously by sulfuration.
Among the present invention, owing to the reinforcing fibre that makes the 1st inboard reinforced layer soaks into the hardened layer that thermosetting resin becomes one, so, in the time of can preventing to arrange the pressurization of the 1st reinforced layer that internal volume expands fully, skidding mutually between reinforcing fibre, swell increment can be suppressed very low.Therefore, can obtain braking the brake rubber hose of sense, good endurance.Before, after weaving the 1st reinforced layer on the interior rubber pipe, cover the 1st reinforced layer surface and fixing with thermosetting resin, not only can not be impregnated into fully between interior rubber pipe and the 1st reinforced layer, and the thickness of the resin layer that covers is also limited, and reinforcing fibre is hardened fully.Therefore, reinforcing fibre skids each other, the changing of the relative positions in the time of can not preventing to pressurize between reinforcing fibre.And make resin liquid be impregnated into reinforcing fibre inside among the present invention, so can make the 1st reinforced layer become hardened layer.
In addition, the outside of the 1st reinforced layer that is hardened by thermosetting resin has the wear resistance performance of height, does not need to prevent the intermediate rubber layer that weares and teares between the 1st reinforced layer and the 2nd reinforced layer.In addition, be solution-type sulfuration binder owing to do not use the rubber that contains solvent, so, can adopt the extrusion moulding of rubber pipe in carrying out continuously and the manufacturing process of the braiding of the 1st reinforced layer, simultaneously, also less than evaporation problem of environment pollution caused because of solvent.
