Description
技术领域
本发明涉及高分子材料技术领域,具体地说是一种用于聚乙烯改性的抗静电阻燃母粒。
背景技术
聚乙烯具有质轻、无毒、成型加工容易、性能价格比高的特点,在很多领域都有广泛的应用,是世界上用量居第二位的通用塑料。但是聚乙烯的氧指数仅占17.0%~17.5%,属于易燃材料,极易造成火灾,在很多应用领域都受到了限制,同时由于聚乙烯又属于电绝缘材料,其表面容易产生静电,给实际生产带来安全隐患。因此对聚乙烯进行抗静电阻燃改性显得尤为重要。通常,对聚乙烯的抗静电阻燃改性一般是加入助剂来完成,但目前使用的助剂大多数均为粉体,在与原料混合时,极不容易混合均匀,而且混合时扬起的粉尘更是污染周围环境和不利于清洁生产等。
发明内容
本发明的目的在于提供一种具有高浓度、低成本和使用方便的用于聚乙烯改性的抗静电阻燃母粒。
本发明解决其技术问题所采用的技术方案是:用于聚乙烯改性的抗静电阻燃母粒,其组分按质量百分数配比为:聚乙烯树脂10%~30%、无卤阻燃剂20%~40%、增强剂20%~40%、抗静电剂10%~20%、分散剂3%~5%、偶联剂1%~3%、抗氧剂1%~2%。
所述无卤阻燃剂为质量比4:1的无卤磷系阻燃剂双酚A-双(二苯基磷酸酯)和硅系阻燃剂聚二甲基硅氧烷的复配物。
所述增强剂为表面经过活化处理的纳米重质碳酸钙、气相纳米二氧化硅、沉淀硫酸钡、无碱玻璃纤维中的一种。
所述抗静剂为抗静电剂HKD-510或抗静电剂HDC-102。
所述分散剂为EVA蜡、OP蜡、乙撑双硬酯酰胺中的一种。
所述偶联剂为硅烷偶联剂、钛酸酯偶联剂、铝酸酯偶联剂中的一种。
所述抗氧剂为受阻酚抗氧剂1076与亚磷酸酯抗氧剂168的复配物。
本发明的用于聚乙烯改性的抗静电阻燃母粒的制备方法为:将各组分按重量配比称好,然后加入高速混合机中一起搅拌3~15分钟,使充分混合均匀后,出料加入双螺杆挤出机熔融挤出,并经过冷却、造粒、干燥和包装后,即得到本发明。
本发明的有益效果是,本发明用于对聚乙烯改性具有分散性好、浓度高、用量少和使用方便等优点,而且还具有较好的力学性能和较高强度,其阻燃性能好,可达无卤、低烟、高效、环保的阻燃要求,同时抗静电性能优良,加工性能好,因而具有很好的实用价值和应用前景。
