Title (EN) ELASTOMERIC NANOCOMPOSITES, NANOCOMPOSITE COMPOSITIONS, AND METHODS OF MANUFACTURE
(FR) NANOCOMPOSITES ÉLASTOMÈRES, COMPOSITIONS DE NANOCOMPOSITE, ET PROCÉDÉS DE FABRICATION
Abstract: front page image
(EN)An elastomeric nanocomposite contains: (a) at least one elastomer comprising units derived from isoolefins having from 4 to 7 carbon atoms; (b) at least 10 phr of a carbon black; and (c) at least 1 phr of a nanoclay; wherein when the nanocomposite is used in an article, the article has a gas permeation coefficient of 80.0 cc*mrn/[m2-day] at 40°C. The carbon black may be graphitized to reduce interactions between the carbon black and the nanoclays. The elastomeric nanocomposite may, with or without the use of the graphitized carbon black, may calendared or extruded in such a manner as to orient the nanoclay platelets within the composition such that the oriented nanoclay elastomer nanocomposite has an orientation parameter of greater than 0.15.
(FR)La présente invention concerne une composition élastomère qui contient : (a) au moins un élastomère comprenant des motifs dérivés d'iso-oléfines ayant de 4 à 7 atomes de carbone; (b) au moins 10 phr d'un noir de carbone; et (c) au moins 1 phr d'une nanoargile; le nanocomposite étant utilisé dans un article, l'article ayant un coefficient de perméation aux gaz de 80,0 cm3*min/[m2-jour] à 40 °C. Le noir de carbone peut être graphitisé pour réduire les interactions entre le noir de carbone et les nanoargiles. Le nanocomposite élastomère peut, avec ou sans l'utilisation du noir de carbone graphitisé, être calandré ou extrudé de manière à orienter les plaquettes de nanoargile dans la composition de sorte que le nanocomposite d'élastomère de nanoargile ait un paramètre d'orientation supérieur à 0,15.
