Description

一种白色聚偏氟乙烯流涎薄膜专用料
技术领域
本发明涉及一种白色聚偏氟乙烯流涎薄膜专用料，专用料适用于流涎工艺，易流动，分散好，用于制备户外使用的耐候、阻隔紫外、阻水隔气的白色薄膜。
背景技术
聚偏氟乙烯(PVDF)是氟塑料家族中重要一员，由于其化学结构C-F键的稳定性，聚偏氟乙烯材料具有优异的抵抗紫外线破坏的能力，并且耐化学腐蚀，具有较低的水汽透过率，目前在太阳能光伏行业、建筑行业、化工领域等广泛应用。
制备塑料薄膜一般有流涎成膜和吹塑成膜两种工艺。相比于吹塑成膜工艺，流涎工艺具有薄膜厚度更均匀、产量更高、薄膜力学性能更优等优点，因此被工业界更广泛采用。流涎法制备PVDF薄膜的难点在于这种材料流动性差，流动黏度比普通聚乙烯大十几倍；同时，熔融塑化难，易产生晶点等外观不良。尤其对于白色聚偏氟乙烯薄膜，由于添加的钛白粉(TiO2)会促进PVDF的分解，使得PVDF分解温度从370℃降低至240℃，并释放剧毒HF，甚至发生材料焦烧、爆炸等危险现象。现有技术中，均采用聚偏氟乙烯与钛白粉直接混合造粒的技术方案，制备得到的聚偏氟乙烯白色薄膜白度不均匀、暗纹明显、晶点多，甚至经常发生原料焦烧等危险。
本发明要解决的技术问题是：研制开发一种白色聚偏氟乙烯流涎薄膜专用料，适用于流涎工艺，熔体流动性好，钛白粉良好分散，受热稳定，可以制备外观良好的白色聚偏氟乙烯流涎薄膜。

进一步地，本发明所述聚甲基丙烯酸甲酯的熔融指数为10～30(g/10min，5kg，230℃)。
进一步地，本发明所述抗氧剂是酚类抗氧剂、有机磷类抗氧剂、硫酯类抗氧剂中的一种或两种以上的混合，优选为1098、168、1010、1076、DLTP、MB、164、264中的一种或两种以上的混合物。
进一步地，本发明所述增容剂为核-壳结构丙烯酸树脂、氟橡胶、硅烷偶联剂中的一种或两种以上的混合。
本发明还提供所述白色聚偏氟乙烯流涎薄膜专用料的制备方法，所述方法为两步法，所述方法包括以下步骤：
(1)制备聚甲基丙烯酸甲酯与钛白粉的母粒：将聚甲基丙烯酸甲酯与钛白粉按照配方比例称取，先用高速混合机混合均匀，混合转速为300～1000rpm，混合时间为5～20min；然后将聚甲基丙烯酸甲酯与钛白粉的混合物加入双螺杆挤出机进行塑化、分散与挤出切粒后得到聚甲基丙烯酸甲酯与钛白粉的母粒，双螺杆挤出机温度为180～250℃，转速为250～500rpm；

本发明提供的白色聚偏氟乙烯流涎薄膜专用料适用于流涎工艺，易流动，分散好，可用于制备户外使用的耐候、阻隔紫外、阻水隔气的白色薄膜。
与现有技术比较，本发明的有益效果是：本发明专用料中的聚甲基丙烯酸甲酯具有很好的流动性及与聚偏氟乙烯良好的相容性，大大改善聚偏氟乙烯的流动性，适用于流涎成膜工艺；两步法中先制备聚甲基丙烯酸甲酯与钛白粉母粒，实现了聚甲基丙烯酸甲酯对钛白粉的表面包覆，于是在第二步中，减少了钛白粉与聚偏氟乙烯接触的概率，减少了钛白粉对PVDF的分解促进作用，从而改善了配方体系的稳定性，避免了成型加工过程中材料发生材料焦烧、爆炸等危险。
