Description
技术领域
本发明属于高分子材料领域,特别涉及一种聚苯硫醚材料及其制备方法。
背景技术
聚苯硫醚(PPS),是一种新型高性能的分子主链中带有苯硫基的热塑性树脂,由于其为结晶性的聚合物,因此具有良好的机械强度和耐高温性能,同时其热稳定性好、电性能优良。聚苯硫醚被广泛用在电子电器、航空航天、汽车运输、机械及化工等领域,是一种综合性能优异的特种工程塑料。
聚苯硫醚被广泛用作结构性高分子材料,通过填充、改性后广泛用作特种工程塑料。同时,还可制成各种功能性的薄膜、涂层和复合材料。但同时,聚苯硫醚伸长率和冲击强度却很低,因此需要加入添加剂,如玻纤、碳纤、填料等来增强其力学性能,特别是抗拉性能、抗弯性能、压缩和冲击强度均需大幅度提高,但改性后的聚苯硫醚其伸长率会发生较大幅度的下降,同时改性后的聚苯硫醚不能再长期负荷和热负荷的作用下保持高的力学性能和尺寸稳定性。

(2)将上述组分加入高压均质机中混合均匀;
(3)然后将步骤(2)中混合均匀的物料加入双螺杆挤出机的加料口,物料经双螺杆挤出机熔融挤出,造粒,制备聚苯硫醚粒料。
所述高压均质机中的混合温度为60-70℃,压强为18-22Mpa。
