| Abstract: | A novel damping material was prepared from toluene diisocyanate(TDI),hexamethylene diisocyanate(HDI),polytetrahydrofuran glycol(PTMG) and caster oil.A kind of diol chain extender with hung-chain structure was added to it.The effects of the kind and mass fraction of hard segment as well as cross linker on the dynamic viscoelasticity and damping properties of polyurethane were studied in detail.The results showed that the damping properties of PU were improved considerably when a diol chain extender was introduced into the molecule and the damping factory of temperature range above Tg was increased in evidence. |
