Composite calcium-base lubricating grease and its preparation
The present invention relates to a calcium complex grease, the grease to a total weight basis, comprising the following components: 1) base oil in an amount of 68 to 95 wt%; 2) calcium complex thickener, an amount of 4 ~ 30 wt%; 3) titanium dioxide content of 0.1 to 8 wt%. He said titanium oxide is present in the grease is preferably in the form of nanoscale particles. The present invention also provides a method for preparing the above-described three kinds of grease. The present invention provides calcium complex grease with good oxidation stability, small change in the value of surface hardening, high dropping point, good anti-wear extreme pressure characteristics. Preparation of grease lubrication can be applied to heavy load equipment at higher temperatures and moisture conditions.
