Description
技术领域
本发明涉及一种复合材料，具体地说是涉及一种抗蠕变防静电棕榈纤维增强聚乙烯复合材料及其制备方法。
背景技术
随着我国经济水平的提高，人们对生活质量的要求也越来越高。居住环境和工作环境作为大家生活中的一大部分，人们对它的要求也越来越高，温度就是其中一部分。面对寒冷的冬天，供暖已成为不可缺少的部分，而空调的使用一般都会使皮肤干燥，并不是人们的首选。地面辐射供暖因温度稳定均匀，不会影响环境湿度而受到欢迎和追捧。以前地面辐射供暖管道一般使用钢管，但是钢管有很多缺陷，如重量大，不易安装；耐腐蚀性能差，需经常维修更换等。现在一般使用聚乙烯管，解决了钢管重量大、不耐腐蚀及韧性差的问题，它具有韧性好、抗腐蚀、抗冲击、耐磨损等一系列优点，然而聚乙烯管存在着管壁太厚、成本过高，当管内压力达到一定高度时，管壁易发生蠕变等一系列问题。全氟乙烯丙烯共聚物具有高强度和高刚度，如果与聚乙烯形成复合材料，就可以增加管的强度和刚度解决蠕变问题，同时减小壁厚。本发明就是为了研制一种抗蠕变防静电棕榈纤维增强聚乙烯复合材料。
发明内容
本发明的目的是提供一种抗蠕变防静电棕榈纤维增强聚乙烯复合材料及其制备方法。
为达到上述目的，本发明所采取的技术方案为：
一种抗蠕变防静电棕榈纤维增强聚乙烯复合材料，由下列重量份的原料配制而成：聚乙烯130-140、全氟乙烯丙烯共聚物20-30、聚醚砜10-15、富马酸松香季戊四醇酯6-8、四乙二醇二庚酸酯5-7、过氧化碳酸二环己酯3-5、乙氧基氨丙基聚二甲基硅氧烷7-9、双(3,5-二叔丁基-4-羟基苄基)硫醚5-7、水杨酸辛酯6-9、双硬脂酸铝4-6、液体石蜡4-5、十八酰胺丙基氧化胺3-5、甲基硫醇锡3-5、环己烷-1,2-二甲酸二异辛酯8-9、棕榈纤维14-16、纳米二氧化硅8-10、导电云母粉10-12、煅烧陶土7-9、碱式氯化镁晶须7-9、石棉粉4-6。
一种抗蠕变防静电棕榈纤维增强聚乙烯复合材料的制备方法，包括以下步骤：
(1)将聚乙烯、全氟乙烯丙烯共聚物在温度为110-115℃的条件下干燥处理50-60min，然后将乙氧基氨丙基聚二甲基硅氧烷喷洒在聚乙烯和全氟乙烯丙烯共聚物的混合物上低速搅拌30-40min，然后在70-75℃的温度下保温2-3h，得到改性混合基料；
(2)将改性混合基料、聚醚砜置于混炼机中在80-90℃的温度下塑炼2-3min，然后加入棕榈纤维、纳米二氧化硅、导电云母粉、煅烧陶土、碱式氯化镁晶须、石棉粉，升温至130℃后继续混炼8-10min，得到聚乙烯混炼物；
(3)将聚乙烯混炼物与富马酸松香季戊四醇酯、四乙二醇二庚酸酯、过氧化碳酸二环己酯、双(3,5-二叔丁基-4-羟基苄基)硫醚、水杨酸辛酯、双硬脂酸铝、液体石蜡、十八酰胺丙基氧化胺、甲基硫醇锡、环己烷-1,2-二甲酸二异辛酯等原料一起加入到捏合机中，在在150-160℃的温度下捏合20-30min后将温度降到40℃以下后出料，制得混合料；
(4)将混合料加入双螺杆挤出机中挤出造粒，设置参数为：模具温度为100℃、注塑机台料筒温度为420℃、成型射压力130MPa、保压为100MPa、背压为0.5MPa，即得所述聚乙烯复合材料。
本发明的有益效果：
本发明的聚乙烯复合材料中采用全氟乙烯丙烯共聚物、聚醚砜与聚乙烯一起共混处理，并添加了棕榈纤维、碱式氯化镁晶须、石棉粉等填料作为增强剂，增强了材料的力学性，提高了材料的抗蠕变性能，解决了聚乙烯材料抗蠕变能力不足的问题；添加的十八酰胺丙基氧化胺、导电云母粉、四乙二醇二庚酸酯等原料提高了聚乙烯材料的抗静电性能。
