Description

一种耐热抗氧化聚氯乙烯发泡管
技术领域
本发明涉及发泡聚氯乙烯技术领域，尤其涉及一种耐热抗氧化聚氯乙烯发泡管。
背景技术
排风设备中输送气体的管道称为风管，它把系统中的各种设备或部件连成了一个整体。风管通常用表面光滑的材料制作例如聚氯乙烯管。聚氯乙烯是五大通用塑料之一，在建材、包装等诸多行业有着广泛的用途。聚氯乙烯发泡材料由于具有轻质、隔热、隔音、高比强度、绝缘等特点更备受青睐，然而发泡材料在带来成本降低的同时，机械性能下降，极大的限制了PVC发泡材料的应用。《聚氯乙烯-蒙脱土发泡复合材料的研究》中利用季铵盐、季膦盐和磷酸酯类插层剂与硅烷偶联剂并用，制备改性蒙脱土，结果表明当蒙脱土份数在1-3phr时，压缩性能、拉伸性能、弯曲性能都有提高，热变形温度和阻燃性随着蒙脱土份数的增加而提高。但是蒙脱土加入过量，在基体中团聚而使发泡材料质量下降，并且该发泡材料的拉伸性能、强度、阻燃性、抗化学腐蚀能力均有待提高。
我国是世界香蕉主产国之一，每年可产香蕉五百百万吨供人们享用，但是伴随着产生的香蕉韧皮、香蕉叶、香蕉假茎等副产品却没有得到应用的开发应用，只有少部分被加工成绳索、麻袋、手提包及其他花式品，绝大部分被当做垃圾丢掉了，这不仅浪费了资源，还污染了环境。所以从香蕉叶中提取香蕉纤维制备成复合材料，对我国的经济发展具有重要的意义。香蕉纤维可分为香蕉茎纤维和香蕉叶纤维，香蕉茎纤维具有一般麻类纤维的优点，如强度高、伸长小、纤维粗硬、易于吸湿放湿、易于染色等特点，香蕉叶纤维具有优良的抗碱、酚、甲酸、氯仿、丙酮能力，将其添加到聚氯乙烯材料中能够减少环境污染带来巨大的经济效益，并且还能够提高聚氯乙烯的抗化学腐蚀能力，但是直接加入会降低聚氯乙烯本身的材料性能，限制其应用，必须对香蕉纤维进行改性，提高其与聚氯乙烯的界面相容性。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种耐热抗氧化聚氯乙烯发泡管。
本发明是通过以下技术方案实现的：
一种耐热抗氧化聚氯乙烯发泡管，由以下重量份的原料制备制成：香蕉叶20-25、0.2%铝酸酯偶联剂1-1.5、偶氮二甲酰胺1.5-2、碳酸氢钠5-6、液体硅胶3-5、十八烷基三甲基氯化铵2.2-2.5、氧化锌0.2-0.3、聚氯乙烯100-110、氧化铝纤维3.4-4、球形二氧化钛0.7-1、片状云母1.3-1.5、氟化石墨2.2-2.5、硅溶胶2-3、石蜡1-2、硬脂酸镁2-3、塑化淀粉1-2、滑石粉7-8、去离子水适量。
所述一种耐热抗氧化聚氯乙烯发泡管，由以下具体步骤制备制成：
（1）将香蕉叶清洗干净晾干后采用压榨、漂白、清洗、烘干的方法提取香蕉纤维，再将香蕉纤维和氧化铝纤维进行混纺并条得到混合纤维条备用；将0.2%铝酸酯偶联剂用75%的乙醇溶解，按照质量比3:4充分混合均匀，再将混合纤维条以浴比1：10浸渍到铝酸酯偶联剂溶液中，加热至溶剂挥发，烘干后备用；
（2）将十八烷基三甲基氯化铵溶于17-19倍量的60-70℃水中，搅拌均匀后加入液体硅胶和塑化淀粉，搅拌溶解再加入球形二氧化钛、片状云母和氟化石墨，在600-800转/分下搅拌形成黏稠浆料；
（3）将步骤（1）制备的改性混合纤维条短切后加到步骤（2）的浆料中，搅拌均匀后和适量的聚氯乙烯在混炼机中混合均匀，加到造粒机中挤出制粒，得到高浓度母粒；
（4）将剩余的聚氯乙烯及其剩余物质加到高速混合机中混合均匀，随后加到热炼机中混合塑化，温度控制在145-155℃，再加入步骤（3）制备的母粒，混合均匀后加到模腔中进行模压发泡，温度控制在185-190℃，时间为2.5-3min，保压压力为15-18MPa，自然冷却即可得到。
本发明的优点是：本发明利用铝酸酯偶联剂改性混纺的香蕉叶纤维和氧化铝纤维条，使香蕉叶纤维中半纤维素和木质素成分减少，使纤维易发生解旋和形变，容易和氧化铝纤维复合，提高了纤维的断裂伸长率和拉伸强度，并且本文制备的黏稠浆料具有优良的抗静电、耐热、耐腐蚀等特性，和混纺纤维混合能够消除其抗电性，提高了与聚氯乙烯的相容性，并且利用一部分聚氯乙烯作为母粒与剩余物料混合，降低生产误差，提高了产品质量稳定性；本发明PVC管材耐热老化性能优异，在较高温度下仍能保持较高的拉伸强度和断裂伸长率，且具有优良的耐磨性、抗氧化、耐化学腐蚀性和耐环境开裂性，经久耐用，应用前景广阔。
