聚苯硫醚对聚醚砜浇铸体性能影响研究

Influence of polyphenylence sulfide on property of polyethersulphone cast

利用热压成型制备了聚醚砜和聚苯硫醚/聚醚砜的浇铸体,并对两种树脂浇铸体吸水性能和力学性能进行了研究。结果表明:以1∶5质量比添加聚苯硫醚到聚醚砜中,热压成型的适宜温度范围增加一倍,复配树脂的抗水分侵蚀能力提高53.7%,抗压缩能力优于单一聚醚砜树脂。在热压温度适宜范围之外,聚醚砜树脂浇铸体力学性能出现大幅下降,复配树脂则下降幅度较小,使用时结构稳定性和安全性较好。

Moisture adsorption and mechanical properties in PES cast and PPS/PES cast were systematically investigated.Cast loaded with a mass rate of 20% of PPS in PES showed more excellent mechanical function and machinability than single PES cast.The rate of water adsorption increased 53.7%,which can guarantee the safe and effective use of PPS/PES cast.
