Colloidal alkaline or alkaline-earth carbonates containing a compound of calcium, phosphorus and sulphur in micellar form |
摘要 |
Colloidal products are described which comprise micelles of alkaline metals or alkaline-earth metals, held in the colloidal state by at least one alkaline metal or alkaline-earth metal alkyl- or alkylarylsulphonate. The products further comprise micelles of a product containing calcium, phosphorus and sulphur resulting from the in situ reaction of calcium oxide or calcium hydroxide with a phosphorus sulphide, in particular tetraphosphorus decasulphide, and water. These colloidal products are used as antiwear and extreme pressure additives for lubricating greases and oils.
