Title (EN) LUBRICATING GREASE COMPOSITION
(FR) COMPOSITION DE GRAISSE LUBRIFIANTE
Abstract: front page image
(EN)A lubricating grease composition comprising base oil and a blended thickener which comprises, as the thickener constituents, (a) one or more urea-type compounds; (b) one or more fatty acid metal salts; and (c) at least one type of amide compound selected from the group comprised of aliphatic amides and aliphatic bisamides shown by the general formulae (1) and (2) : R1CONH2 (1), R1CONHR2NHCOR1 (2), wherein R1 denotes a saturated or unsaturated alkyl group having from 15 to 17 carbon atoms and R2 denotes a methylene group or an ethylene group and wherein the blending weight proportions of (a) , (b) and (c) are in the ratio of a / (b + c) is in the range of from 0.20 to 10 wherein (1) constituent (a) has a blending weight ratio in the range of from 1 to 10; (2) constituent (b) has a blending weight ratio in the range of from 0.5 to 2.5; and (3) constituent (c) has a blending weight ratio in the range of from 0.5 to 2.5.
(FR)L'invention concerne une composition de graisse lubrifiante contenant une huile de base et un épaississant mélangé qui renferme comme constituants d'épaississant, (a) au moins un composé de type d'urée, (b) au moins un sel métallique d'acide gras, et (c) au moins un type de composé d'amide sélectionné parmi le groupe composé d'amides aliphatiques et de bisamides aliphatiques présentés par la formule générale (1 et 2) : R1CONH2 (1), R1CONHR2NHCOR1 (2), où R1 désigne un groupe alkyle saturé ou insaturé possédant 15 à 17 atomes de carbone et R2 désigne un groupe méthylène ou un groupe éthylène. Les proportions pondérales du mélange de (a), (b) et (c) se situent dans le rapport a / (b + c) allant de 0,20 à 10. (1) Le constituant (a) possède un rapport pondéral de mélange compris entre 1 et 10, (2) le constituant (b) a un rapport pondéral de mélange compris entre 0,5 et 2,5, et (3) le constituant (c) a un rapport pondéral de mélange allant de 0,5 à 2,5.
