| 摘 要： | 以通用型PVC树脂为基体,使用EPDM-g-MAH通过双螺杆挤出机对其进行共混改性,研究了EPDM-g-MAH的含量对EPDM-g-MAH与PVC共混合金的力学性能的影响。结果表明:随着EPDM-g-MAH含量的增加,合金的拉伸强度降低;断裂伸长率升高但有波动,超过20%后,不断增大;在EPDM-g-MAH含量0～5%范围内,合金的冲击强度随着弹性体的增加,5%时出现极大值,随后冲击强度有波动,在超过20%后,合金的冲击强度随EPDM-g-MAH含量的增加而增大。

| Abstract: | General-purpose ABS resin was used for matrix,and modified through twin-screw extruder,blended with EPDM-g-MAH.The effects of the EPDM-g-MAH content on EPDM-g-MAH and PVC alloy were studied.The results showed that:as EPDM-g-MAH content increased,tensile strength inclined,tensile elongation at break increased but had a fluctuation,above 20% the impact strength increased.The impact strength increased firstly when its content was up to 5%,the impact strength had a maximum value.Above 5%,the impact strength had... |
