PURPOSE:To obtain the titled resourse-saving composition having excellent surface accuracy, mechanical properties, and frictional and abrasion resistance, and high recycling characteristics, by compounding a PPS resin with a polymer- based powdery solid lubricant and potassium titanate fiber. CONSTITUTION:A polyphenylene sulfide resin is compounded with 5-20(wt)% polymer-based powdery solid lubricant and fibrous resinforcing materials consisting of 10-40% potassium titanate fiber and 3-20% carbon fiber. The weight ratio of potassium titanate fiber to carbon fiber is 1-10. The solid lubricant is selected from polytetra-fluoroethylene, high-density polyethylene and ultra-high- molecular-weight polyethylene having an average particle diameter of <=100mum. |
