Description

低VOC耐水解性聚氨酯泡沫及其制备方法
技术领域
本发明属于聚氨酯泡沫及其制备方法及用途领域，特别是关于低VOC耐水解性聚氨酯泡沫及其制备方法和用途。
背景技术
聚氨酯泡沫具有突出的物理性能，广泛应用于汽车工业中。近年来汽车制造商向其泡沫供应商提出的需求更加严格，尤其是聚氨酯泡沫的有机挥发物(VOC)含量及气味方面的标准要求更加严格。VOC中文释意为有机挥发物，具有嗅觉，有刺激性，而且具有一定毒性。VOC主要包括醛类、胺类、苯类化合物、低分子醇类。按照国家标准GB18586-2001规定，选择较为严格的VOC定义，熔点低于室温而沸点在50～260℃之间的有机挥发物的总称，包括苯、甲苯、二甲苯以及其他有机挥发性物质，该标准规定其VOC总量小于35ppm。在聚氨酯泡沫塑料中主要存在以下4种挥发性有机化合物：(1)抗氧剂BHT或BHT同系物。这类抗氧剂主要来源于多元醇，因此常常不被重视；(2)泡沫稳定剂，主要以有机硅为基础的化合物；(3)催化剂，主要包括叔胺类有机物和二价或四价有机锡化合物；(4)挥发性阻燃剂，阻燃剂的含量越高，挥发性也就越高。因此，要降低聚氨酯材料中的VOC含量，需要选择或改造聚氨酯发泡用原材料，才能有效减少有机挥发物的存在。耐水解性是指按照国家标准DIN EN ISO2440耐水解老化后最大形变百分比。
中国专利20131006308.4介绍了一种低VOC聚氨酯泡沫及其制备方法，原料包括聚醚多元醇混合料和异氰酸酯混合料得到低VOC聚氨酯泡沫VOC含量为24ppm，具有62％的落球回弹率，芯密度可达54.8kg/m3。
中国专利20161125060.3介绍了一种聚氨酯汽车顶蓬组合料，组分A包括聚醚多元醇、聚合物多元醇、聚酯多元醇、扩链剂、泡沫稳定剂、催化剂、助剂；组分B为多次甲基多苯基异氰酸酯或改性多次甲基多苯基异氰酸酯，该聚氨酯板材的甲醛含量为0.11ppm，乙醛含量为0.18ppm。
