REINFORCED FIBROUS POLYACRYLONITRILE MIXTURE FOR FRICTION PRODUCT AND ITS PRODUCTION |
摘要 |
<p>An improved fibrous polyacrylonitrile mixture for use in friction products enables the production of low resiliency preforms by mixing an additive with a polyacrylonitrile wet gel. The additive is incorporated into the fiber in extremely large amounts. The additive is a member selected from the group consisting of: (a) polyethylene glycol ester of pelargonic acid; or (b) polyethylene glycol esters of enanthic, caprylic or capric acids; or (c) blends of polyethylene glycol esters of enanthic, caprylic, pelargonic, or capric acids; or (d) blends of polyethylene glycol esters of carboxylic acids derived from natural products containing at least 50% by weight of carboxylic acids containing less than 14 carbon atoms; or (e) reaction products of ethylene oxide and carboxylic acid amides wherein at least 70% of the acids from which the amide is derived contain between 16 and 20 carbon atoms. ;</p> |
