Abstract

Le problème décrit par la présente invention consiste à fournir un nouveau lubrifiant qui est apte à supprimer le grippage de matériaux métalliques en raison du frottement entre les matériaux métalliques. La solution pour résoudre le problème mentionné ci-dessus porte sur un lubrifiant qui contient un minéral argileux de type smectite et des ions ammonium obtenus par cationisation d'une amine primaire, d'une amine secondaire ou d'une amine tertiaire, et où : les ions ammonium sont intercalés entre des couches du minéral argileux de type smectite ; l'amine primaire, l'amine secondaire ou l'amine tertiaire contient un ou plusieurs groupes alkyle à chaîne longue, dont chacun comporte 8 atomes de carbone ou plus dans la chaîne principale ; et le nombre total d'atomes de carbone dans les chaînes principales des groupes alkyle à chaîne longue est de 16 ou plus.
