Abstract
The KH-550 was modified by KH-560, and a new surfactant was got, which was used to modify nanosilicon carbide. Series of modified polyurethane elastomers (PUE) were prepared with 2,4-toluene diisosocyanate (TDI), poly (propylene glycol)(PPG-2000), modified nanosilicon carbide, carbon nanofibers and 3,3'-4,4'-dianino-diphenymethane (MOCA). The influence of different amount of filler on the mechanical properties, wear resistance of composite materials was investigated. The dispersion degree of nanofiller in matrix was analysised by SEM. The results showed that the comprehensive properties of composite had been greatly improved.
