Description
技术领域
本发明涉及高分子材料技术领域,尤其涉及一种低线性膨胀系数聚丙烯复合材料及其制备方法。
背景技术
聚丙烯树脂(PP)是一种用途非常广泛的通用塑料,由丙烯单体聚合制备,因其质轻、化学稳定性好、易加工成型、较好的机械性能、不吸水、耐化学腐蚀、综合成本低等诸多优点被广泛应用于诸多领域。在很多日常生活领域,根据零部件的使用环境及要求,会针对性的对聚丙烯材料进一步改善从而提高其综合力学性能,具体方式有填充、复配等改性。
但目前填充改性聚丙烯的一大难点就是,如何降低材料的线性膨胀系数,在很多地区,随着四季的变化,环境温度发生很大改变,材料的线性膨胀系数高低从而决定了制件的尺寸稳定性;尤其在一些特殊领域,如汽车后背门外板、前仓盖板外板等,材料的基本力学性能通过改性均可以满足使用要求,但由于外板材料是与内板材料(LFT-PP)是胶粘在一起后使用,这就需要两种材料之间的线性膨胀系数匹配,否则随着环境温度的变化,从而造成内、外板胶粘失效而分离。因此,寻求一种低线性膨胀系数聚丙烯复合材料的制备显得非常有必要。

优选地,所述聚乙烯为高密度聚乙烯(HDPE)、低密度聚乙烯(LDPE)、线性低密度聚乙烯(LLDPE)中的至少一种;所述过氧化物引发剂为过氧化二已丙苯(DCP)、过氧化二叔丁基(DTBP)、过氧化苯甲酸叔丁酯(TPB)中的至少一种。
优选地,所述聚丙烯为共聚聚丙烯,其在2.16kg,230℃条件下的熔体流动速率为5~100g/10min。
优选地,所述无机填料为滑石粉、钛酸钙、硫酸钡、云母中的至少一种;所述增韧剂为POE、EPDM、SEBS中的至少一种;所述相容剂为PP接枝马来酸酐(PP-g-MAH)、POE接枝马来酸酐(POE-g-MAH)或其组合。
优选地,所述其他助剂为抗氧剂、润滑剂、耐UV剂、颜料中的至少一种。
一种所述的低线性膨胀系数聚丙烯复合材料的制备方法,包括:按重量份数,称取聚丙烯、交联聚乙烯母粒、无机填料、增韧剂和其他助剂,混合均匀,加入挤出机中,经过熔融、挤出、造粒、冷却、烘干,即得。
