| 摘 要： | 将2种乙烯-醋酸乙烯酯共聚物（EVM400，EVM700）和2种热塑性聚氨酯弹性体（聚酯型TPU385E和聚醚型TPU8685）按不同并用比进行交叉共混，考察了共混体系的耐油性能。结果表明，3#标准油较1#标准油对EVM／TPU共混胶性能影响大，且VA含量低的EVM400共混胶比VA含量高的EVM700共混胶受3#标准油的影响大；EVM700／TPU385E共混胶具有最好的耐油性；EVM／TPU共混胶并用比为50／50时．浸油前后性能变化最大，即耐油性最差。

| Abstract: | The oil resistance of the blend was investigated by cross-blending two kinds of EVM(ethylene-vinyl acetate copolymer with different VA content) and two kinds of thermoplastic PU elastomer(TPU)(polyester and polyether type) in different rates.The results showed that 3# oil had more significant influence to the property of EVM/TPU copolymer than 1# oil,the influence to EVM400 was larger than that to EVM700;the EVM700/TPU385E blend had the best oil resistance;the oil resistance was the worst as the rate of EVM/TPU was 50:50. |
