Abstract
本发明属于聚氨酯泡沫塑料合成技术领域，具体涉及一种卷闸门用聚氨酯保温隔音材料及其制备方法，所述聚氨酯保温隔音材料采用聚醚多元醇、环氧大豆油多元醇、阻燃剂、物理发泡剂、催化剂、化学发泡剂、泡沫稳定剂和降粘剂为A组分；多甲基多苯基多异氰酸酯作为B组份；按质量比A组分：B组分＝1:1‑1.5混合浇注即可。本发明的卷闸门用聚氨酯保温隔音材料，在配方中引入环氧大豆油多元醇和EO封端的聚醚多元醇使得聚氨酯发泡料在低温下不酥脆，具有流动性好、阻燃、质量轻的特点。聚氨酯材料填充在卷闸门门片空腔内，不改变卷闸门原有外观和使用空间，操作简单，提高卷闸门的保温隔热、隔音效果，降低建筑的整体能耗。
Description
技术领域
本发明属于聚氨酯泡沫塑料合成技术领域，具体涉及一种卷闸门用聚氨酯保温隔音材料及其制备方法。
背景技术
卷闸门又称为卷帘门，是以很多关节活动的门片串联在一起，在固定的滑道内，以门上方卷轴为中心转动上下的门。由于其良好的开合性能而广泛应用于闭合宽度较宽的门体结构或不适于设置常规旋转结构的门体结构。
建筑节能是关系到我国建设低碳经济、完成节能减排目标、保持经济可持续发展的重要环节之一，而卷闸门作为建筑的一个主要组成部分，对建筑节能有着重要的作用，常规的卷闸门主要是金属材料隔热、隔音效果差，不能满足节能和舒适的要求。
发明内容
本发明要解决的技术问题是：克服现有技术的不足，提供一种卷闸门用聚氨酯保温隔音材料及其制备方法，将聚氨酯材料填充在卷闸门门片空腔内，在不改变卷闸门原有外观和使用空间的前提下，可大大提高卷闸门的保温隔热效果，同时具质量轻、隔音效果好的特点，有利于建筑节能减排，提高室内舒适性。
为解决上述技术问题，本发明的技术方案如下：
本发明所述的卷闸门用聚氨酯保温隔音材料，由A、B双组份组成，其中：
以重量份数计，A组份包括以下组分：
B组分为：
多甲基多苯基多异氰酸酯。
其中：
所述的聚醚多元醇，选自下列聚醚多元醇中的一种或多种：
聚醚多元醇A，以蔗糖或者山梨醇与棕榈油、甘油、丙二醇或乙二醇中的一种或者两种作为复合起始剂，以氧化丙烯作为聚合单体制备而成；优选一诺威R5118G、R6001C或R4110B中的一种或多种；
聚醚多元醇B，以赛克为起始剂，以氧化丙烯作为聚合单体制备而成，羟值为150-350mg KOH/g，粘度200-400mpa.s；

本发明所述的卷闸门用聚氨酯保温隔音材料的制备方法，包括以下步骤：
(1)A组份的制备：将聚醚多元醇、环氧大豆油多元醇、阻燃剂、催化剂、化学发泡剂、泡沫稳定剂以及降粘剂降温后加入物理发泡剂，搅拌0.5-1.5小时，取出进行检验，满足设定发泡参数，即可装桶备用；
(2)使用时，将A组分和B组分按照A:B＝1:1-1.5的质量比，进行混合发泡，即可制成卷闸门用聚氨酯保温隔音材料。
与现有技术相比，本发明的有益效果如下：
1、本发明使用环氧大豆油多元醇，其中低分子物质含量少，可以提高泡沫的韧性，避免在低温下使用出现粉脆的现象，同时与钢板、铝材等基材具有良好的粘结力。环氧大豆油多元醇中的脂肪酸链提供了与烷烃类发泡剂良好的相溶性，是一种的可再生、可降解产品。
2、本发明采用二醇醚酯类降粘剂，由于其自身结构和聚醚一样含有碳氧碳键，与体系的互溶性好，能够有效降低体系粘度，有利于泡沫和基层的浸润，提高泡沫粘结力。同时降粘剂稳定存在于聚氨酯的交联网络结构中，可以提高泡沫的柔韧性。
3、本发明采用S320和S227聚醚多元醇，聚合时加入环氧乙烷，同时分子链相对较长，聚醚反应活性高，在低温下与异氰酸酯反应性好，不会出现酥脆现象。
4、本发明采用采用赛克起始剂聚醚、TEP使得聚氨酯泡沫具有较好的阻燃性能，泡沫不含卤素，绿色环保。
5、本发明卷闸门用聚氨酯保温隔音材料具低温不酥脆、有流动性好、阻燃性好的特点，聚氨酯材料填充在卷闸门门片空腔内，操作简单易行，不改变卷闸门原有外观和使用空间，能够提高卷闸门的保温隔热、隔音效果，降低建筑的整体能耗，聚氨酯泡沫密度40-60kg/m3，对卷闸门整体质量影响很小。

表1实施例1-4和对比例1-2制备的聚氨酯泡沫性能测试结果
本发明实施例1-4制得的卷闸门用聚氨酯材料具有导热系数低、低温不酥脆、阻燃性好的特点，与基材粘结强度高。结合实施例1和对比例1可以看出，当组合聚醚中不加环氧大豆油多元醇和EO封端的聚醚多元醇S320或者S227时泡沫低温下酥脆情况比较严重，与基材基本不粘；当组合聚醚中不加S320和S227聚醚多元醇时，泡沫与基材的粘结力较差，但是泡沫基本不酥脆。说明环氧大豆油多元醇对泡沫低温下酥脆情况有较大改善，EO封端的聚醚多元醇可以进一步提高泡沫与基材的粘结强度。
