SILOXANE-BASED LUBRICATING COMPOSITION, NOT RELEASING HYDROGEN, PREPARATION METHOD AND USE THEREOF |
摘要 |
The invention concerns a lubricating composition, in the form of an oil-in-water emulsion, based on siloxane and not releasing hydrogen comprising: (a) a polydiorganosiloxane oil non-reactive to the lubricating properties having a dynamic viscosity of the order of 5.10<-2 >to 30.10<2 >Pa.s at 25° C.: (b) a reactive linear polydiorganosiloxane oil having per molecule at least two OH groups, said polydiorganosiloxane having a dynamic viscosity at 25° C. ranging between 5.10<-2 >to 30.10<2 >Pa.s: (c) a crosslinking agent soluble in the silicone phase comprising at least two functions capable of reacting with the reactive polydiorganicsiloxane oil (b); (d) a water soluble crosslinking agent: (e) a surfactant: (f) a condensation catalyst capable of catalysing the reaction of oil (b) with the crosslinking agent (c) and/or (d): and (g) water: compositions comprising a soluble polyorganosiloxane soluble in the silicone phase and bearing, before emulsification, condensable hydroxyl substitutes being excluded. |
