Abstract

MAZIVNI SESTAVEK. Sestavek, ki obsega (a) sol enovalentne kovine (M) in karboksilne kiseline kjer je skupina COOH vezana na obročni atom kondenziranega obročnega sistema, in (b) mazivo, ki je ne-milno zgoščeno olje, ki je lahko mineralno olje ali sintetsko olje, kot silikonsko olje. Kovina (M) je lahko natrij. Kondenziran obročni sistem je prednostno kondenziran aromatski ogljikovodični obročni sistem, kot naftalen in lahko vključuje nadaljnje substituente, npr. skupino OH poleg skupine COOH. Če kislina vsebuje tako skupino OH kot tudi skupino COOH, sta lahko ti vezani na sosednja atoma kondenziranega obročnega sistema. Ugotovili smo, da sta zlasti primerna natrijev 2-naftoat in natrijev 3-hidroksi-2-naftoat. Mazivo ima izboljšano korozijsko odpornost in dodatek kovinske spojine ne povzroči destrukturiranje maziva.LUBRICANT COMPOSITION. A composition comprising (a) a monovalent metal (M) and carboxylic acid salt wherein the COOH group is attached to the ring atom of the condensed ring system, and (b) a lubricant which is a non-soapy concentrated oil which may be a mineral oil or a synthetic oil. , as silicone oil. The metal (M) may be sodium. The fused ring system is preferably a fused aromatic hydrocarbon ring system, such as naphthalene, and may include further substituents, e.g. an OH group in addition to the COOH group. If the acid contains both an OH group and a COOH group, these may be attached to adjacent atoms of the condensed ring system. Sodium 2-naphthoate and sodium 3-hydroxy-2-naphthoate have been found to be particularly suitable. The lubricant has improved corrosion resistance and the addition of a metal compound does not cause destruction of the lubricant.
