    摘要： A method for preparing urea grease excellent in low noise properties comprises the step of adding a base oil in which an amine (or an isocyanate) is dissolved or dispersed, to a base oil in which an isocyanate (or an amine) is dissolved or dispersed, in the form of liquid drops having a diameter of not more than 300 .mu.m to react the isocyanate with the amine; or the step of directly contacting liquid drops comprising a base oil in which an isocyanate is dissolved or dispersed and having a diameter of not more than 300 .mu.m with liquid drops comprising a base oil in which an amine is dissolved or dispersed and having a diameter of not more than 300 .mu.m to react the isocyanate with the amine. The method permits the production of urea grease excellent in low noise properties at a low cost.
