RESIN COMPOSITION EXCELLENT IN SLIDING CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To obtain a resin composition excellent in sliding characteristics in a lubricating oil and also sliding characteristics in the absence of a lubricating oil. SOLUTION: This resin composition comprises (A) a polyamide resin, (B) an acrylic granular resin and (C) carbon black. The acrylic granular resin has been swollen by a lubricating oil and the carbon black has 90-270mg/g iodine absorption number. The resin composition has a composition composed of 100 pts.wt. of the component A, 5-40 pts.wt. of the component B and 10-40 pts.wt. of the component C. The resin composition has sliding characteristics of <0.058 dynamic coefficient of friction and <0.006mm<3> /Nkm comparative abrasion quantity.
