HOSE COMPRISING MODIFIED NYLON 6,12 MATERIAL |
摘要 |
A copolymer of nylon 6 (caprolactam mer units) and nylon 12 (dodecanolactam mer units) and/or nylon 11 (undecanolactam mer units), which has been modified to provide improved physical properties, such as flex modulus, elastic modulus, and yield strength, serves as a layer of a hose suited to use in airbrake applications. The modified copolymer is resistant to degradation by zinc chloride and moisture and thus may be used as a peripheral layer of the hose in place of a conventional protective layer comprising a pure polyamide, such as nylon 11 or 12. Alternatively, the modified copolymer may be used as a tie layer for rendering a peripheral layer comprising nylon 12 or 11 compatible with a layer of nylon 6, allowing the less expensive nylon 6 material to comprise the bulk of the hose thickness. The layer includes a compatibilizer, such as a maleic anhydride grafted polyethylene, and may also include plasticizers and impact modifiers. |
