    摘要： The present invention is based on the unexpected discovery that the fluid resistance of hoses can be greatly enhanced by adding a chlorinated paraffin to a chlorinated polyethylene elastomer or a chlorosulfonated polyethylene elastomer which is used as the tubular inner core layer of the hose. Hoses made using this approach offer the advantage of having improved resistance to modern automotive fluids, including power steering fluid, transmission fluid, and the like, without compromising flexural characteristics or burst strength. Accordingly, the hoses of this invention provide a longer service life and better reliability then hoses made utilizing conventional technology. The present invention more specifically discloses a hose which is comprised of (1) an elastomeric tubular inner core layer defining a lumen, (2) a friction layer, and (3) an elastomeric cover, wherein the elastomeric tubular inner core layer is comprised of (i) a chlorinated elastomer selected from the group consisting of epichlorohydrin, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, (ii) 1 phr to 50 phr of a chlorinated paraffin, and (iii) 30 phr to 120 phr of carbon black. It is typically preferred for the chlorinated elastomer to be chlorinated polyethylene or chlorosulfonated polyethylene.

    摘要翻译： 本发明基于意想不到的发现，通过将氯化石蜡加入氯化聚乙烯弹性体或用作软管的管状内核层的氯磺化聚乙烯弹性体，可以大大提高软管的流体阻力。 使用这种方法制造的软管具有改善对现代汽车流体的抵抗力的优点，包括动力转向液，传动液体等，而不损害弯曲特性或爆裂强度。 因此，本发明的软管提供使用常规技术的软管更长的使用寿命和更好的可靠性。 本发明更具体地公开了一种软管，其包括（1）限定内腔的弹性体管状内芯层（12），（2）摩擦层（14）和（3）弹性体盖（30），其中 弹性管状内芯层（12）由（i）选自表氯醇，聚氯丁二烯，氯化聚乙烯和氯磺化聚乙烯的氯化弹性体组成，（ii）1phr至50phr氯化石蜡，和（iii） ）30phr至120phr的炭黑。 氯化弹性体通常优选为氯化聚乙烯或氯磺化聚乙烯。
