Description

一种耐热变形的聚乙烯发泡塑料及其制备方法
技术领域
本发明涉及聚乙烯发泡塑料，尤其涉及一种耐热变形的聚乙烯发泡塑料及其制备方法。
背景技术
聚乙烯发泡塑料作为一种保温材料，具有很多的优点：质轻、密度小，容重约为20～40kg/m3；导热系数小，一般在0.017～0.027(w/m·k)之间；吸水率低，具有较强的防水性。由于聚乙烯发泡塑料具有以上优点，因此比较适用于空调系统的保温，特别是洁净度要求高的空调系统，不允许用玻璃棉等易产生纤维屑的材料作风管系统的保温材料，那么价格适中的聚乙烯发泡塑料便是很好的代用品。
但是聚乙烯发泡塑料不宜在高温下使用，当温度超过70℃后，聚乙烯发泡塑料管套会出现融缩变形，从而发生与管道空离的现象，也即聚乙烯发泡塑料管套与管道分离，这样会影响聚乙烯发泡塑料的保温效果。
发明内容
本发明的主要目的在于提供一种耐热变形的聚乙烯发泡塑料及其制备方法，从而可以解决现有技术中聚乙烯发泡塑料在高温下使用时与管道分离的现象。
为达到以上目的，本发明提供一种耐热变形的聚乙烯发泡塑料，由以下重量百分比含量的原料制得：双酚A型环氧树脂4～5％、聚乙烯缩丁醛0.5～1.0％、二乙烯三胺0.6～0.9％、环氧改性有机硅树脂3～4％、乙酸钾0.2～0.5％、偶氮二甲酰胺6～8％，余量为低密度聚乙烯。
所述聚乙烯发泡塑料通过以下步骤制备：
(1)将双酚A型环氧树脂、聚乙烯缩丁醛、二乙烯三胺、环氧改性有机硅树脂、乙酸钾和低密度聚乙烯按照上述比例加入密闭式炼胶机中，于140～150℃混炼均匀，然后再加入偶氮二甲酰胺，于155～160℃混炼均匀后出料，得到混炼料；
(2)将所述混炼料装入模具，再送入平板硫化机进行交联发泡，温度为160～175℃，压力为10～12MPa，保压时间为15～20min；
(3)保压完成后，压力骤降，完成发泡，得到所述聚乙烯发泡塑料。
本发明提供的聚乙烯发泡塑料容重约为23～28kg/m3，导热系数为0.020～0.024(w/m·k)，能够在100℃环境下24小时不会出现融缩变形，从而解决了背景技术中提到的聚乙烯管套与管道空离的现象，而且改性后的聚乙烯发泡塑料无污染，力学性能也达到了保温材料的使用要求。
聚乙烯发泡塑料中加入的双酚A型环氧树脂固化后具有良好的物理、化学性能，制品尺寸稳定性好、硬度高，同时也有利于提高聚乙烯发泡塑料的耐热性；加入聚乙烯缩丁醛可以对双酚A型环氧树脂进行改性，提高双酚A型环氧树脂的抗冲击柔性，同时还可以提高双酚A型环氧树脂与低密度聚乙烯的相容性；二乙烯三胺为双酚A型环氧树脂和环氧改性有机硅树脂的固化剂，使用二乙烯三胺作为固化剂，可以使双酚A型环氧树脂在140℃以上不变形；加入环氧改性有机硅树脂有利于提高聚乙烯发泡塑料的耐热性，同时环氧改性有机硅树脂与双酚A型环氧树脂很好的相容；加入乙酸钾可以降低环氧改性有机硅树脂的固化温度。
