Description
技术领域
本发明涉及塑胶跑道材料技术领域,具体是一种高填充热塑性弹性体塑胶跑道材料的制备方法。
背景技术
在热塑性弹性体加入填料、助剂等制备的热塑性塑胶跑道材料具有质量稳定、力学性能优异、工艺成熟、价格适中、环保可回收等比较优势,在国内多个运动场地已获得推广应用。填料的添加既能节省树脂用量降低成本,又能改进基材的外观、力学、热性能、阻燃性能等,还能降低能量消耗和环境污染。工业上常用的填料主要是无机物,包括有碳酸钙、氧化锌、氧化镁/氢氧化镁、氧化铝/氢氧化铝等,这些无机物来源广泛、储量丰富、经济性好;加入这些填料的塑料广泛用于吹膜、拉丝、电缆等多个领域。在这些应用过程中最大的问题是填料的填充率不高,同时还存在相容性差、容易析出、力学性能劣化明显等问题,造成这些现象的原因是无机填料与热塑性弹性体之间的界面性能不匹配,工业上常规的解决方式是加入硬脂酸及其盐、马来酸酐接枝物等来调节界面极性改善二者之间的相容性,这种方法可以提高填充量,但程度有限,未能彻底的解决上述不足,充分发挥热塑性弹性体基材和无机填料各自优异的性能。
发明内容
本发明的目的在于提供一种高填充热塑性弹性体塑胶跑道材料的制备方法,以解决上述背景技术中提出的问题。
为实现上述目的,本发明提供如下技术方案:一种高填充热塑性弹性体塑胶跑道材料的制备方法,包括以下步骤:
步骤一:准备原料,所述原料组成包括热塑性弹性体主基材、增强树脂、油剂、无机填料、原位表面改性剂;
步骤二:将无机填料与原位表面改性剂按照质量分数比在高速混合机的常温条件下低速混合一定时间,然后加入一定量的LDPE/LLDPE和引发剂,混合一段时间后用双螺杆在一定温度下挤压初混成颗粒,得到核壳结构的无机填料母粒,然后用365-410nm的紫外光或蓝光引发完成二次引发接枝;
步骤三:将热塑性弹体主基材与油剂在常温状态下进行混合,然后加入一定量的增强树脂与步骤二中所得到的核壳结构的无机填料母粒进行混合,然后利用双螺杆熔融混合后挤压出辊压成型得到高填充热塑性弹体塑胶跑道材料。
作为本发明进一步的方案:所述原料添加的分量均按照质量分数比进行添加,其中热塑性弹性体主基材80-120份、增强树脂100-150份、油剂100-300份、无机填料200-500份、原位表面改性剂10-20份。
作为本发明进一步的方案:所述热塑性弹性体主基材为SEBS/SEPS中的一种或两种的混合物,所述增强树脂为PP/POE/LDPE中的一种或数种的混合物;所述油剂为白油、环烷油中的一种或两种的混合物;所述无机填料为碳酸钙、氧化锌、氧化镁、氧化铝的一种或数种的混合物;所述原位表面改性剂为核壳结构LDPE/LLDPE的丙烯酸或甲基丙烯酸接枝物;所述引发剂为光、热引发剂的复配物。
作为本发明进一步的方案:所述无机填料与原位表面改性剂在20-60℃、10-300RMP的条件下先混合1-5 min,所述LDPE/LLDPE和引发剂再在20-60℃、10-300 RMP的条件下混合1-5 min,而后用双螺杆在60-120℃条件下挤出共混成粒状。
与现有技术相比,本发明的有益效果是:
1、利用丙烯酸、甲基丙烯酸等液态可聚合的表面改性剂在填料表面进行原位反应形成完整的包覆层,而后利用热和光引发接枝,得到以无机填料为核、接枝聚合物为壳的填料母粒;极性的羧基与填料表面的金属钙、镁、铝等离子形成强相互作用,现在填料核的表面形成完整的改性包覆层,与之相连的壳层接枝聚合物与后加入的热塑性弹性体基材因极性相近而发生分子量的缠结,可显著提高填料与基材之间的相容性,进一步提高力学性能、加工性能、柔软性、耐候性、耐油性、耐低温性等;
2、先制备核壳结构的填料母粒,而后加入基材、增强树脂、油剂等制备高填充热塑性弹性体塑胶跑道材料,填料以母料加二次熔融共混的过程最终分散在材料中,显著提高在最终产品中填料的分散状况,进一步提高材料的力学性能、性能的稳定性及综合物性。
