    摘要: A urea-urethane grease composition contains, as essential ingredients, a thickener and a lubricant base oil. The thickener contains a urea-urethane mixture having a composition including 20 to 99, mol.% of a diurea comoound reoresented bv the aeneral formula (I) of
    4 to 30 mol.% of a urea-urethane compound represented by the general formula
    and 1 to 50 mol.% of a diurethane compound represented by the general formula
    wherein R 1 represents a difunctional aromatic hydrocarbon residue having 6 to 15 carbon atoms, R 2 a cyclohexyl group or a group derived from cyclohexyl and having 7 to 12 carbon atoms and R 3 an alkyl group or an alkenyl group having 8 to 20 carbon atoms. The ratio of the numbers of amino groups R 2 -NH-to those of alkoxy groups R 3 -O-in the mixture being 95 / 5 to 40/60. The thickener is contained in an amount of 2 to 25 wt.% based on the total weight of the grease composition.

    摘要: A diurea grease composition contains a base oil and 2 to 25 wt.%, based on the total weight of the composition, of a diurea compound, the diurea grease compound being produced by reacting a mixed system of two or more different diisocyanates represented by the formula (I) OCN-R-NCO wherein R stands for a straight-chained or branched alkylene group, a straight-chained or branched alkenylene group, a cycloalkylene group or an aromatic group, with an amine compound of a primary amine represented by the formula (II) R₁-NH₂ wherein R₁ stands for a hydrocarbon residue having 6 to 20 carbon atoms, a secondary amine represented by the formula (III)
    wherein R₂ and R₃ each stand for hydrocarbon residues having 6 to 20 carbon atoms, or mixtures thereof.
