Title
(EN) IMPROVED RUBBER COMPOUND FOR TRACKED VEHICLE TRACK PADS
(FR) MELANGES DE CAOUTCHOUC AMELIORES POUR PATINS DE CHENILLE DE VEHICULES A CHENILLES
Abstract
(EN)
A highly improved elastomeric composition, process, and articles made thereof, wherein the novel composition is characterized by greatly increased wear longevity, thermomechanical stability, highly improved tear and tensile strength at high temperature usage, in addition to high resistance to burning in open flame, as well as high resistance to cutting, chipping, cracking and crack propagation particularly in product use for tank track pads and other related track system elastomeric component products; wherein the improved composition is a unique combination of its respective polymer, filler, curing and antidegradant systems, in which the polymer system either consists of about 100 parts by weight of highly saturated nitrile polymer or of various novel blends of the highly saturated nitrile usually in majority amounts together with minority amounts of carboxylated nitrile, with or without additional minority or near equal parts of nitrile rubber; and wherein the curing system may include various blends of from between about 1.5 to about 30 parts by weight of a metallic oxide, along with from between about 25 to about 50 parts by weight of a metallic methyl-methacrylate resin, together with from about 0.25 to about 3 parts by weight of a curative compound; which composition is further well suited for manufacture of various abutment and motion stop or limit members subjectable to repetitive engagement by moving mechanisms, and for various at least semi-flexible baffle or skirt-like members useable with various air cushion type vehicles or the like.
(FR)
Un composé élastomère hautement amélioré, procédé de production, et articles fabriqués avec ce composé. Celui-ci se caractérise par une résistance à l'usure considérablement augmentée, une stabilité thermomécanique, une résistance à la déchirure et à la tension fortement améliorée lors d'une utilisation à hautes températures, s'ajoutant à la résistance à la combustion à la flamme nue, ainsi qu'une résistance élevée aux coupures, à l'effritement, à la fissuration et à la propagation de fissures notamment dans l'utilisation de produits destinés à des patins de chenilles de chars et autres produits à constituants élastomères de systèmes de chenilles apparentés. Le composé amélioré est une combinaison unique de ses systèmes de polymères, de charges, de vulcanisation et d'antidégradants respectifs, dans laquelle le système de polymères se compose soit d'environ 100 parties en poids de polymère nitrile hautement saturé soit de différents mélanges nouveaux de nitrile hautement saturé habituellement dans des quantités majoritaires avec des quantités minoritaires de nitrile carboxylé, avec ou sans parties supplémentaires minoritaires ou presque égales de caoutchouc nitrile. Le système de vulcanisation peut comprendre différents mélanges comprenant entre environ 1,5 et 30 parts en poids d'un oxyde métallique, avec environ 25 à 50 parts en poids d'une résine de méthyle-méthacrylate métallique, ainsi qu'environ 0,25 à 3 parts en poids d'un mélange vulcanisant. La composition est en outre bien adaptée pour la fabrication de divers éléments de butée et d'arrêt ou de limite de mouvement soumis à un engrènement répété par des mécanismes en mouvement, et pour divers éléments d'écran ou similaires à une jupe au moins semi-flexibles, utilisables avec divers véhicules de type à coussins d'air ou analogue.
