PURPOSE:To provide the titled compsn. having improved moldability, particularly improved frictional and wear characteristics, by blending a liquid lubricant, a specified additive, a nonionic surfactant, a fibrous filler and a solid lubricant with a synthetic resin. CONSTITUTION:The titled compsn. is obtd. by blending 2-15pts.wt. liquid lubricant, 0.1-2pts.wt. at least one member selected from higher fatty acids, their salts and their alkyl esters (e.g. stearic acid, zinc stearate, butyl stearate, etc.) and further 0.2-15pts.wt. nonionic surfactant (A), 10-40pts.wt. fibrous filler (B-a) such as carbon fiber and 5-30pts.wt. solid lubricant (B-b) such as graphite (with the proviso that the combined quantity of components B-a and B-b is not more than 50pts.wt.) with 100pts.wt. synthetic resin such as polyacetal. By blending component A, the liquid lubricant is prevented from separating, and the frictional and wear characteristics as well as moldability can be improved. By blending components B-a and B-b, the frictional and wear characteristics can be still further improved. |
