Description

一种防火保温型PE复合材料及其制造工艺
技术领域
本发明涉及一种PE材料，尤其是一种兼具防火和保温功能的PE复合材料。 
背景技术
建筑外墙保温材料是节能建筑的重要组成部分，用于节能建筑，可减少建筑物室内冷热负荷，降低制冷或采暖能耗。保温材料的应用不仅要考虑对整个建筑保温的作用，还应考虑火灾发生时保温材料的易燃等级和防止火灾蔓延措施。
目前，常用的外墙保温材料使用聚氨酯或聚苯乙烯泡沫塑料，单纯的此类原料阻燃等级较低，一旦发生火灾易引起火灾快速蔓延。
近年来，本领域基于传统的PE塑料发展了多种复合PE材料，这种复合材料一般是通过向其中加入砂浆或有机物实现的，聚焦于改进防火性能。实际施工发现，此类材料尽管在防火性能上取得了一定进步，但是保温性能显著降低。同时，大量使用砂浆等填料，使得产品的制造成本升高，不利于推广应用。
发明内容
针对现有技术的不足，本发明公开了一种PE复合材料，通过采用无机料与有机物匹配，产生了显著地协同效果，其防火效果好，保温功能强。
具体地说，本发明是通过如下技术方案实现的：
一种防火保温型PE复合材料，以PE颗粒为基料，加入添加料；所述添加料为木屑、发泡剂、耦合剂和玻化微珠颗粒；其中添加料的用量为基料质量的15-25％。
其中，所述木屑尺寸在0.1～0.3厘米；发泡剂为碳酸氢钠或铝粉；耦合剂为钛酸酯或硅烷；玻化微珠为粒径0.3～0.5㎜的膨胀玻化微珠。
通过使用上述原料作为添加料，发泡剂和玻化微珠在耦合剂作用下形成对木屑显微结构的支撑和填充，形成细密实心泡孔；包裹于PE原料外层后对其形成显著地保护作用，一方面抑制了热传导，提高保温效果；另一方面，外层的添加料又具有良好的耐火性能并有效抑制温差效应下的空气流动，具有良好的防火效果。
其中，添加料的组成，以质量分数计：木屑1-2、发泡剂1-2、耦合剂1-1.5、玻化微珠颗粒1.5-2。
优选的，添加料中各成分质量相同。
在上述基础上，本发明还公开了所述防火保温型PE复合材料的制备工艺，包括将木屑、 发泡剂、耦合剂和玻化微珠颗粒混合均匀制成添加料和将添加料粘贴于PE原料颗粒外层的步骤。
申请人进行的实验显示，本发明的防火保温型PE复合材料，以PE防火保温为基础，结合有机物、无机物混合，防火保温效果好，节能环保，有利于大规模推广和大范围应用。
具体实施方式
在如下实施中，申请人公开了本发明若干具体实现。如下所提供的实施仅为示意性的，并不限制本发明的保护范围。本领域技术人员在理解和掌握本发明实质精神的基础上所做出的改进和改变，依旧属于本发明的保护范围。
