聚丙烯多功能黑色母粒的研制
Journal of University of Souht China (Science & Technology)(2014)
Abstract
以聚丙烯( PP)树脂为研究对象,制备抗静电防老化的多功能黑色母粒,其关键技术在于解决各种功能助剂、着色剂、分散剂及载体树脂的品种、数量、配比组合及相容性、协同性问题.实验首先选择载体树脂和各种助剂,然后通过正交实验确定多功能黑色母粒的最佳配比.结果表明:载体树脂为40 kg,色素为30 kg,抗静电剂为2 kg,抗氧剂为5 kg,分散剂为20 kg,增容剂为3 kg是制备100 kg多功能黑色母粒的最佳配比.用该功能母粒制备的聚丙烯板材的表面电阻系数为3.8×109,氙灯老化72 h后色牢度为4级.
