Because of this method, the unvulcanized hose 3 that has become plasticized in the initial stage of vulcanization may be deformed on the contact surface of the pallet 2 and may remain as a scratch. Therefore, in order to prevent this, a method is also used in which the unvulcanized hose 3 is coated with lead and then vulcanized using a vulcanizing can. However, this method requires high equipment costs and a step to peel off the lead coating.

ゴムホース３の外表面が硬化される。FIG. 2 shows a main part of this pre-UV oA equipment 5, that is, a sectional view taken along the line A--A in FIG. 1. That is, in this device 5, the unvulcanized rubber hose 3 is covered with a cylindrical jacket 6.
Two mercury lamps 7 are arranged on the left and right sides of the almost central part of the jacket 6, and the outer surface of the unvulcanized rubber hose 3 is extruded from two points on the left and right of the mercury lamps 7. The structure is such that ultraviolet rays are irradiated in a direction perpendicular to the direction. In addition, 8 beams in the same figure are flapers. A mercury lamp 7 of 80 W/c1 is used, and the distance from the unvulcanized rubber hose 3 to the mercury lamp 7 is set to about 10 to 15 cm. The irradiation time of the unvulcanized rubber hose 3 can be from several seconds to 2 minutes, and is usually set to about 10 seconds to 60 seconds. This is because if the time exceeds 2 minutes, the temperature of the rubber hose will rise to 70°C or higher, which is undesirable from the standpoint of deterioration. When the unvulcanized rubber hose 3 transported through the ultraviolet irradiation device 5 passes, the surface of the unvulcanized rubber hose 3 is irradiated with ultraviolet rays, and the outer surface of the unvulcanized rubber hose 3 is cured.

０℃、３０分〜６０分とした。Next, the unvulcanized rubber hose 4 wound up on the pallet 2 after being irradiated with ultraviolet rays was placed together with the pallet 2 in a predetermined vulcanizing can and vulcanized. This vulcanization condition is 15
The temperature was 0°C for 30 to 60 minutes.

Further, as the material constituting the unvulcanized rubber hose 3, chlorine-containing rubber can be used, such as chlorosulfonated polyethylene rubber, epichlorohydrin rubber, chloroprene rubber, etc.

ムホースの劣化も少なく、冷却装匠も必要としない。Since the surface of the rubber hose manufactured in the above embodiment is hardened by UV irradiation before being vulcanized, even if the unvulcanized hose 4 is wound up on the pallet 2 after being irradiated with UV rays and vulcanized. There were no scratches on its surface. Furthermore, in this example, by simply providing a step in which the extruded unvulcanized rubber hose passes through an ultraviolet irradiation device, it was possible to easily manufacture a scratch-free rubber hose. Furthermore, in this example, since the temperature of the unvulcanized rubber hose after irradiation with ultraviolet rays is less than 70° C., the rubber hose does not deteriorate much and no cooling device is required.

料の種類によっては混入させることもできる。That is, as the material used for the unvulcanized rubber hose, the above-mentioned halogen-containing rubber material is preferred from the viewpoint of ease of vulcanization, but any material that can be vulcanized by ultraviolet irradiation may be used. Further, as the conditions for irradiating ultraviolet rays, various preferable values are set depending on the rubber material used, the capacity of the mercury lamp, the distance to the irradiation object, the irradiation time, etc. For example, mercury lamps are not limited to those in the above embodiments, but are usually 30.12
A mercury lamp of 0.160 W/c1 can be used, and the distance to the irradiation object and the irradiation time are variously set depending on the capacity of the mercury lamp used. Also, if the temperature of the rubber hose becomes high (e.g. 70℃ or higher) due to the irradiation conditions,
The temperature can also be adjusted to an appropriate temperature using a cooling means. Further, the number of mercury lamps used is not limited to two, but may be one or three or more. Although the unvulcanized rubber does not contain a photoreaction initiator as in the above embodiments, it may be mixed depending on the type of hose material.

The case is not limited to winding up as in the above embodiment, but it is also possible to simply place the sheet without winding it up. In particular, the former is applied to long objects, and the latter is applied to short objects.

Therefore, according to this method of manufacturing a rubber hose, when an unvulcanized rubber hose is placed on a pallet after being irradiated with ultraviolet rays and then vulcanized, the rubber hose placed on this pallet will not be scratched, and therefore the vulcanized rubber hose will not be scratched. Visual inspection of the appearance of the rubber hose after sulfurization becomes unnecessary. Furthermore, according to this manufacturing method, a rubber hose with a good appearance can be manufactured. Furthermore, in this manufacturing method, it is sufficient to simply perform ultraviolet irradiation midway through the process, so the equipment cost is low and the number of steps can be reduced, resulting in a large overall cost reduction. Furthermore, according to the present manufacturing method, the rubber hose is less likely to deteriorate than the conventional method of curing the surface using an electron beam.
