| 摘 要： | 用大豆油多元醇替代石化聚醚多元醇制备出了硬质聚氨酯泡沫塑料（RPUF），考察了石化聚醚多元醇和大豆油多元醇的比例以及RPUF密度对RPUF性能的影响。结果表明，随着大豆油多元醇用量的增加，RPUF的冲击强度和压缩模量减小，压缩屈服点逐渐消失，玻璃化转变温度升高；但随着大豆油基RPUF密度的增加，其冲击强度、压缩模量和储能模量都得到了提高，压缩模量最高可达56.44 MPa。 |

| Abstract: | Petrochemical polyol was partially replaced with soybean oil-based polyol in the preparation of rigid polyurethane foam(RPUF).The effects of fraction of soybean oil-based polyol and density of RPUF on the properties of RPUF were studied.It showed that with increasing contents of soybean oil-based polyol,the impact strength and compression modulus of RPUF reduced,however,the yield point gradually disappeared,and glass-transition temperature increased.With increasing density,the impact strength,compression modulus,and storage modulus of RPUF increased,the compression modulus reached 56.44 MPa. |
| Keywords: | soybean oil-based polyol rigid polyurethane foam mechanical property thermal stability |
