層６から構成される。Reinforced rubber hoses are widely used as fluid transfer pipes, pressure transmission pipes, etc. in industrial, aircraft, and marine applications. For example, as shown in FIG. 1, this hose is composed of an inner rubber 1 constituting an inner tube, a reinforcing layer 2 made of wire or fiber, and an outer protective cover layer 6 made of resin or rubber material.

製造工程が煩雑化する欠点がある。Conventionally, when manufacturing such a hose, the reinforcing layer 2 was braided in a plaid shape or a spiral shape while the inner rubber 1 was in an unvulcanized or semi-vulcanized state. but,
When the inner surface rubber 1 is unvulcanized, the reinforcing layer 2 partially bites into the inner surface rubber 1 as shown in FIG. 2, creating braid holes in the reinforcing layer 2. To prevent this, the inner surface rubber 1 It may be necessary to cool and harden the front plate, or the inner rubber 1
There are drawbacks such as dimensional disturbances caused by rubber flow during vulcanization. Furthermore, when the inner rubber 1 is semi-vulcanized, the surface of the inner rubber 1 is completely free of tack, so the inner rubber 1 and the reinforcing layer 2 are bonded together via the adhesive layer 4 as shown in FIG. Since various adhesive treatments such as etc. must be performed, the manufacturing process has the disadvantage of becoming complicated.
本発明は、上述した事情にかんがみて製造工程の簡略化

する。The present invention was made in view of the above-mentioned circumstances in order to simplify the manufacturing process and stabilize product performance, and provides a reinforced rubber hose with stable pressure resistance and shock resistance, and an advantageous manufacturing method thereof. The purpose is to provide law.

び耐衝撃性を有することになる。To manufacture this reinforced comb hose A, first, unvulcanized inner rubber 1 made of natural comb or synthetic rubber (CR, NBR, SBR, etc.) is extruded using an extruder. Next, the entire circumferential surface of this inner rubber 1 is irradiated with radiation. In this case, the radiation dose may be about IMrad to 30 Mrad. This irradiation hardens the outer surface of the inner comb 1 to form a hardened layer a. Next, a reinforcing layer 2 is laminated on this hardened layer a. In this case, since the hardened layer a is an extremely thin layer and does not lose its adhesiveness, the inner surface comb 1 and the reinforcing layer 2 will stick to each other. Next, vulcanization is performed by a conventional method. Reinforced rubber hose A obtained in this way
As shown in FIG. 5, since the inner surface comb 1 and the reinforcing layer 2 are in close contact with each other through the hardened layer a, it has stable pressure resistance and impact resistance.

可能である。As described above, according to the present invention, since the surface of the inner rubber is hardened by radiation irradiation, there is no need for various adhesive treatments, so the manufacturing process can be simplified, and dimensional fluctuations can be reduced. Since this does not occur, product performance can be stabilized. The present invention is applicable to various types of hoses ranging from low-pressure hoses to high-pressure hoses.
