Description

一种耐腐蚀聚四氟乙烯板材的制备方法
技术领域
本发明涉及聚四氟乙烯加工技术领域，具体涉及一种耐腐蚀聚四氟乙烯板材的制备方法。
背景技术
聚四氟乙烯被称“塑料王”，具有优良的化学稳定性、抗酸抗碱、耐腐蚀性是当今世界上耐腐蚀性能最佳材料之一，同时，聚四氟乙烯具有耐高温的特点，它的摩擦系数极低，所以可作润滑作用之余，它的产生解决了化工、石油、制药等领域的许多问题。
聚四氟乙烯材料，由于其优良的耐化学腐蚀性、耐高温性、耐低温性以及介电性能，得到了广泛的应用。聚四氟乙烯板材更是被应用于耐腐蚀衬里材料及密封衬里，支持滑块、导轨、电绝缘零件。目前的聚四氟乙烯板材，都为单纯的聚四氟乙烯本体，这种单一的聚四氟乙烯板材的强度普遍不高，大大限制了其在化工，机械等领域的运用。
发明内容
本发明旨在提供了一种耐腐蚀聚四氟乙烯板材的制备方法。
本发明提供如下技术方案：
一种耐腐蚀聚四氟乙烯板材的制备方法，包括如下步骤：

(2)向上述得到的混合物中加入抗氧剂7-11份、交联剂9-15份、纳米填料6-10份、加工助剂9-13份混合，加入带有搅拌机的反应釜中，在温度为65℃下，搅拌9分钟，搅拌转速为250r/min，将搅拌后的混合物送入双螺杆挤出机，料筒和机投温度为145℃，螺杆转速为150r/min，自然冷却定型得所述耐腐蚀聚四氟乙烯板材。
所述热固性合成树脂由酚醛树脂和乙烯基树脂按照重量比3:2混合组成。
所述抗氧剂为抗氧剂168和抗氧剂1010复配物。
所述交联剂由三烯丙基异三聚氰酸酯和二亚乙基三胺组成。
所述纳米填料为纳米二氧化硅、纳米碳酸钙、纳米二氧化钛按照重量比3:2:2混合组成。
所述加工助剂为增塑剂、稳定剂、固化剂按照重量比3:1:2组成的混合物，所述增塑剂为磷苯二甲酸二脂，所述稳定剂为亚磷酸三苯脂，所述固化剂为三乙烯四胺。
与现有技术相比，本发明的有益效果是：本发明选用的超高分子量聚乙烯作基材具有优异的耐磨性、可载性及良好的抗刮擦性，通过本方法加工的板材密度小，重量轻，硬度高，韧性好，具有较好的耐火性、耐腐蚀性、耐油性、耐磨性和防静电能力，适用于各种形状的平面密封。
