Abstract
本发明提供一种车窗用密封胶，其特征在于，以质量份计，含有如下组分：溶剂，二甲基硅油1份，聚乙二醇1份，醋酸纤维素1～3份，聚异丁烯1份，酪蛋白0.5～2份，聚四氢呋喃0.2份。根据本发明的车窗用密封胶，未采用任何有害于人体的挥发性物质做为原料，同时，采用醋酸纤维素、酪蛋白和聚乙二醇的混合物作为主要胶粘成分，因此，挥发物成分含量极少，有效减少了车内污染。
Description
技术领域
本发明涉及一种车窗用密封胶，属于汽车材料领域。
背景技术
近年来车内装饰越来越多样化，同时，车内装饰在生产制造和安装的过程中会使用大量胶粘剂，而胶粘剂通常会含有挥发性有机化合物(VOC)，是车内污染的主要来源。
发明内容
本发明的目的在于提供一种VOC含量低的汽车用胶粘剂，用于车内车窗的密封条部位，尤其是车门上的升降车窗的密封条，减少VOC的含量，绿色环保。
本发明采用了如下技术方案：
一种车窗用密封胶，其特征在于，以质量份计，含有如下组分：溶剂，二甲基硅油1份，聚乙二醇1份，醋酸纤维素1～3份，聚异丁烯1份，酪蛋白0.5～2份，聚四氢呋喃0.2份。
进一步，本发明的车窗用密封胶，还可以具有如下技术特征：其中，醋酸纤维素与酪蛋白的质量比为：1.5：1～5：1。
进一步，本发明的车窗用密封胶，还可以具有如下技术特征：还具有：甘油1份。
作为优选，本发明的车窗用密封胶，还可以具有如下技术特征：其中，醋酸纤维素与酪蛋白的质量比为：2：1～4：1。
作为进一步的优选，本发明的车窗用密封胶，还可以具有如下技术特征：其中，醋酸纤维素与酪蛋白的质量比为：4：1。
作为优选，本发明的车窗用密封胶，还可以具有如下技术特征：其中，聚异丁烯与酪蛋白的质量比为1：2～1：0.5。
作为进一步的优选，本发明的车窗用密封胶，还可以具有如下技术特征：其中，聚异丁烯与酪蛋白的质量比为2：1。
进一步，本发明的车窗用密封胶，还可以具有如下技术特征：其中，溶剂为异丙醇，质量份为2份。
发明的有益效果
根据本发明的车窗用密封胶，未采用任何有害于人体的挥发性物质做为原料，同时，采用醋酸纤维素、酪蛋白和聚乙二醇的混合物作为主要胶粘成分，因此，挥发物成分含量极少，有效减少了车内污染。
另外，由于醋酸纤维素、酪蛋白和聚乙二醇这几种胶粘物质之间具有复杂的侧链交联特性，具有较好的弹性，因此在车窗上下运动时，使用本发明胶粘剂的密封条位置会具有较好的弹性。减少了密封条与车窗间的硬性接触，提升了车窗升降的顺畅感。
具体实施方式
以下结合具体实施方式来进一步说明本发明的技术方案。
实施例一
实施例一的配方如下，各组分均以质量份计：
实施例二
实施例二的配方如下，各组分均以质量份计：
实施例三
实施例三的配方如下，各组分均以质量份计：
实施例四
实施例四的配方如下，各组分均以质量份计：
本实施方式的粘性为各实施方式中最佳。
实施例五
实施例五的配方如下，各组分均以质量份计：
以上各实施例的组分混合均匀后，根据《GBT27630-2011乘用车内空气质量评价指南》中的方法检测TVOC含量。各项有机挥发物的含量均远低于国标。
然后，采用本发明的车窗用密封胶，进行裸露测试，具体方法为：取单位面积的玻璃板，将单位质量的本发明的密封胶均匀涂布在玻璃板上，自然风干后，放入封闭检测箱中，放置1小时后检测TVOC含量，检测值为，0.001～0.002mg/m3远远小于国标。上述单位面积为1m2，单位质量为100g。室内TVOC国标：小于0.5mg/m3。
本发明中的溶剂采用异丙醇，在具体实施时，溶剂可采用性质与异丙醇类似的其它溶剂，并不限定于异丙醇这一种，当然，溶剂的用量也可以根据密封胶的固化时间来酌情使用，并不限定于上述实施方式中所使用的量。
