POWDER-FILLED ELASTOMER COMPOSITE MATERIAL

摘要

PURPOSE:To obtain the titled composite composition having excellent friction and abrasion characteristics and sliding characteristics free from damage of contacting material in sliding motion and exhibiting the characteristics especially under condition of high pressure and high speed operation, by compounding a thermoplastic elastomer with powdery titanium and powdery silicon nitride. CONSTITUTION:About 20-95pts.wt. of a thermoplastic elastomer or a polyurethane elastomer free from thermoplastic nature is compounded with about 40-2.5pts.wt. of powdery titanium and about 40-2.5pts.wt. of powdery silicon nitride. The thermoplastic elastomer is selected from thermoplastic polyurethane, polyester elastomer and polyolefin elastomer. The composite material may be a compound produced by reacting a polyol component with a diisocyanate component in the presence of powdery titanium and silicon nitride.
