Multilayered elastomer hose with reinforcement layer consisting of sulfur-containing polymer material
View Patent ↗The present invention relates to a multilayered elastomer hose comprising at least an inner layer, an outer layer and a reinforcement layer. To enhance the loadability of conventional elastomer hoses while maintaining the typical flexible structure, it is intended according to the invention that the reinforcement layer comprises a sulfur-containing polymer material.
1. A multilayered elastomer hose comprising at least an inner layer, an outer layer and a reinforcement layer, wherein the reinforcement layer comprises polyarylene sulfide having arylene units selected from one or more of: phenylene, biphenylene, naphthylene, anthracene or phenanthrene.
2. The multilayered elastomer hose according to claim 1 , wherein the polyarylene sulfide contains more than 50 mol percent arylene sulfide units.
3. The multilayered elastomer hose according to claim 1 , wherein the reinforcement layer contains polyphenylene sulfide.
4. The multilayered elastomer hose according to claim 1 , wherein the reinforcement layer contains at least one reinforcement fiber or at least one reinforcement yarn with the sulfur-containing polymer material.
5. The multilayered elastomer hose according to claim 1 , wherein the reinforcement layer contains at least one reinforcement fiber or at least one reinforcement yarn of the sulfur-containing polymer material.
6. The multilayered elastomer hose according to claim 5 , wherein the reinforcement fibers or reinforcement yarn are entwined with one another at least in part.
7. The multilayered elastomer hose according to claim 1 , wherein the reinforcement layer is positioned at least in sections between the inner layer and the outer layer.
8. The multilayered elastomer hose according to claim 5 , wherein the reinforcement fiber or the reinforcement yarn spirally surrounds the inner layer at least in sections.
9. The multilayered elastomer hose according to claim 1 , wherein the reinforcement layer contains polyphenylene sulfide.
10. The multilayered elastomer hose according to claim 9 , wherein the reinforcement layer contains at least one reinforcement fiber or at least one reinforcement yarn with the sulfur-containing polymer material.
11. The multilayered elastomer hose according to claim 10 , wherein the reinforcement layer contains at least one reinforcement fiber or at least one reinforcement yarn of the sulfur-containing polymer material.
12. The multilayered elastomer hose according to claim 11 , wherein the reinforcement fibers or reinforcement yarn are entwined with one another at least in part.
13. The multilayered elastomer hose according to claim 12 , wherein the reinforcement layer is positioned at least in sections between the inner layer and the outer layer.
14. The multilayered elastomer hose according to claim 8 , wherein the reinforcement fiber or the reinforcement yarn spirally surrounds the inner layer at least in sections.
