Description
技术领域
本发明涉及电缆材料技术领域，尤其涉及一种用于A类阻燃聚乙烯电缆料的制备方法。
背景技术
聚乙烯护套材料是一种常用的质轻、无毒环保、具有优异电绝缘性能的热塑性塑料，广泛的应用于电线电缆领域。由于以前的电线电缆多为PVC制品，PVC制品有毒有害，不环保，燃烧后会释放出大量的有毒有害气体，造成的危害极大。低烟无卤聚烯烃电缆为了满足低烟和无卤两个要求，而大量加入无机阻燃剂，致使材料的开裂性能大幅度下降而不能满足要求。因此，需要开发阻燃聚乙烯电缆料，保证材料具有良好的阻燃性同时，同时使得该材料具有优异耐开裂性能。
发明内容
本发明目的在于提供一种用于A类阻燃聚乙烯电缆料的制备方法，该制备方法获得的A类阻燃聚乙烯电缆料在保证阻燃性能的同时，延长了阻燃聚乙烯耐环境应力开裂时间，超过了260小时，使得燃聚乙烯电缆料形成电缆护套后，具有更好的耐环境应力开裂性能。
为达到上述目的，本发明采用的技术方案是：一种用于A类阻燃聚乙烯电缆料的制备方法，包括如下步骤：
步骤一、将熔体流动速率为3~8g/10min高密度聚乙烯树脂100份、线性低密度聚乙烯树脂35 ~55份、马来酸酐接枝乙烯醋酸乙烯酯5~15份、炭黑3~5份、氢氧化铝50~60份、氢氧化镁10~30份、磷氮阻燃剂2~8份、金属皂类润滑剂3~6份加入密炼机中，然后开始混炼，混炼至料温为120℃~150℃获得第一混合料；
步骤二、在第一混合料中添加抗氧剂0.5~2份、邻苯二甲酸二异壬酯1~5份、丙烯酸月桂酯2~5份、超支化聚乙烯亚胺1~3份，在密炼机中混炼，混炼温度为100~110℃，得到第二混合料；
步骤三、将第二混合料送入双螺杆挤出机中，在160~170℃下挤出造粒，获得所述聚乙烯电缆料。
上述技术方案中进一步改进的技术方案如下：
1、上述方案中，所述金属皂类润滑剂为硬脂酸钙或硬脂酸锌。
2、上述方案中，所述抗氧剂为抗氧剂1010、抗氧剂1076、抗氧剂168、抗氧剂626、抗氧剂300P中的一种。
3、上述方案中，所述磷氮阻燃剂为三聚氰胺、聚磷酸三聚氰胺、焦磷酸二三聚氰胺、正磷酸三聚氰胺、聚磷酸铵、磷酸酯三聚氰胺盐、二新戊二醇间苯二胺双磷酸酯和新戊二醇磷酸酯三聚氰胺盐中的至少一种。
4、上述方案中，所述线性低密度聚乙烯树脂的熔体流动速率为0.05~2 g/10min。
5、上述方案中，所述步骤一中混炼时间为30~60分钟，所述步骤二中混炼时间为10~15分钟。
由于上述技术方案的运用，本发明与现有技术相比具有下列优点：
本发明用于A类阻燃聚乙烯电缆料的制备方法，其基于氢氧化铝50~60份、氢氧化镁 10~30份、磷氮阻燃剂 2~8份添加了丙烯酸月桂酯2~5份、超支化聚乙烯亚胺1~3份，在保证阻燃性能的同时，克服了由于添加三种类型阻燃剂导致开裂性能变差的缺陷，延长了阻燃聚乙烯耐环境应力开裂时间，超过了260小时，使得获得的燃聚乙烯电缆料形成电缆护套后，具有更好的耐环境应力开裂性能。

对比例3中金属皂类润滑剂为硬脂酸锌，抗氧剂为抗氧剂300P，所述磷氮阻燃剂为正磷酸三聚氰胺，上述线性低密度聚乙烯树脂的熔体流动速率为2 g/10min，高密度聚乙烯树脂的熔体流动速率为4g/10min。
上述实施例1~4制得的A类阻燃聚乙烯电缆料，性能如表3所示：
表3
上述对比例1~3制得的A类阻燃聚乙烯电缆料，性能如表4所示：
表4
如表3和表4的评价结果所示，实施例1~4制得的A类阻燃聚乙烯电缆料，耐环境应力开裂时间，均超过了260 h；对比例1~3制得的A类阻燃聚乙烯电缆料，耐环境应力开裂时间最长时间为218h。因此，本发明实施例制备方法获得的A类阻燃聚乙烯电缆料, 在保证阻燃性能的同时，延长了阻燃聚乙烯耐环境应力开裂时间，超过了260小时，使得燃聚乙烯电缆料形成电缆护套后，具有更好的耐环境应力开裂性能。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
