Abstract (en)
[origin: WO2008034892A2] The present invention aims to offer a urea grease composition which excels in noise performance, has long life at high temperatures and, further, also provides the basic performance of greases such as shear stability and heat resistance, as well as appropriate oil separation properties. The present invention provides a urea grease composition comprising: a diurea compound as shown by the General Formula (A) below: R<SUP>11</SUP>NHCONHR<SUP>12</SUP>NHCONHR<SUP>13</SUP>.... (A), (where R<SUP>11</SUP> and R<SUP>13</SUP> are groups selected from the group consisting of hydrocarbon groups having from 6 to 20 carbons, at least one of R<SUP>11</SUP> and R<SUP>13</SUP> is a dodecyl group and R<SUP>12</SUP> is a diphenylme thane group); and a diurea compound as shown by the General Formula (B) below: R<SUP>21</SUP>NHCONHR<SUP>22</SUP>NHCONHR<SUP>23</SUP>.... (B), (where R<SUP>21 </SUP> and R<SUP>23</SUP> are groups selected from the group consisting of hydrocarbon groups having from 6 to 20 carbons, at least one of R<SUP>21</SUP> and R<SUP>23</SUP> is an oleyl group, and R<SUP>22</SUP> is a diphenylmethane group).
