Abstract: front page image
(EN)Antimony dithiocarbamate is known to provide extreme pressure (EP) protection in lubricating compositions, such as grease. However, there is a desire to reduce the amount of antimony used in such compositions, while still maintaining acceptable EP performance. It has now been found by using small amounts of either ammonium dithiocarbamate or zinc dithiocarbamate in combination with the antimony dithiocarbamate (SbDTC), a lower amount of SbDTC can be used in the lubricating composition while still maintaining excellent or exceptional EP protection. To counteract the corrosive effects of the SbDTC and ammonium dithiocarbamate composition, it has been found that compounds containing a carboxylic acid group are effective in avoiding copper corrosion.
(FR)Le dithiocarbamate d'antimoine est réputé pour sa résistance aux pressions extrêmes (EP) dans les compositions lubrifiantes, telles que la graisse. Cependant, il est souhaitable de réduire la quantité d'antimoine utilisée dans ces compositions, sans que cela réduise les propriétés de résistance aux EP des compositions. Il s'est avéré que si l'on utilise de petites quantités de dithiocarbamate d'ammonium ou de dithiocarbamate de zinc avec le dithiocarbamate d'antimoine (SbDTC), une plus petite quantité de SbDTC peut être utilisée dans la composition lubrifiante, cette dernière conservant des propriétés de résistance aux EP excellentes ou exceptionnelles. Pour lutter contre les effets de la corrosion de la composition de SbDTC et de dithiocarbamate d'ammonium, on utilise des composés contenant un groupe acide carboxylique qui permettent d'éviter la corrosion du cuivre.
