The present invention relates to a process for heavy alkylate based less toxic
metalworking fluid composition comprising heavy alkyl benzene, one emulsifier
which is a sodium oleate, sulfonate or mixtures thereof, a vegetable oil as
lubricity booster, an antioxidant, a fungicide, an extreme pressure additive,
an antirust, a co-surfactant, a coupling agent and alkali component. The
process comprises removing of insoluble matter from the heave alkylate,
addition of emulsifier, additives, coupling agent and co-surfactant,
homogenizing the mixture at 20 - 120~C, followed by conditioning of the metal
working fluid concentrate which can be used as emulsion in water.
La présente invention concerne un procédé d'obtention d'une composition de fluide de transformation de métaux moins toxique à base d'alkylate lourd, contenant du benzène d'alkyle lourd, un émulsifiant constitué d'un oléate de sodium, d'un sulfonate de sodium ou de mélanges de ceux-ci, une huile végétale comme lubrifiant, un antioxydant, un fongicide, un additif extrême-pression, un antirouille, un cosurfactant, un agent de couplage et un composant alcali. Le procédé consiste à éliminer une matière insoluble de l'alkylate lourd, à ajouter l'émulsifiant, les additifs, l'agent de couplage et le cosurfactant, à homogénéiser le mélange à 20 - 120·C, puis à conditionner le concentré de fluide de transformation des métaux pouvant être utilisé comme une émulsion dans l'eau.
