Description
技术领域
本发明涉及胶黏剂技术领域，具体为一种无污染的无溶剂双组份聚氨酯胶黏剂及其制备方法。
背景技术
在新基建建设所涉及的电子器件、新能源汽车、轨道列车等领域，高性能胶黏剂起着举足轻重的作用。电子器件的封装与散热，汽车及轨道列车的焊接、涂装、装配以及内饰等各个制造环节，都离不开高端胶黏剂的使用。胶黏剂在这些领域发挥着粘接、密封、传导、减震，甚至是作为部件结构基体，已成为不可或缺的一部分。随着人们对环保、高性能新材料的要求愈加严格，聚氨酯胶黏剂的技术提升要求已十分迫切。无溶剂胶黏剂是一种不用任何溶剂即可进行使用的胶黏剂，是环保型胶黏剂的重要品种之一。
目前的溶剂挥发气味大，对周围环境造成污染，因此，需要一种对环境无污染，具有气味小、不燃、储存稳定等优点，符合当今的环保理念的无溶剂双组份聚氨酯胶黏剂。
发明内容
本发明的目的在于提供一种无污染的无溶剂双组份聚氨酯胶黏剂及其制备方法，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：一种无污染的无溶剂双组份聚氨酯胶黏剂，以重量份计，材料组成成分包括对苯二甲酸二甲酯15-45重量份、乙二醇5-20重量份、间苯二甲酸10-30重量份、癸二酸5-15重量份、聚醚多元醇20-30重量份、异佛尔酮二异氰酸酯10-30重量份、六亚甲基二异氰酸酯15-30重量份、聚二烯多元醇20-40重量份以及1，4一丁二醇10-45重量份。
进一步的，包括以下制备方法，具体步骤如下：
步骤一、合成聚酯多元醇：在反应釜中投入对苯二甲酸二甲酯、乙二醉、间苯二甲酸﹑己二酸、1,4-丁二醇和催化剂，开始加热搅拌通入氮气，升温到135℃，出甲醇进行酯交换反应，然后逐渐升温到180℃待甲醇出至理论量时，投入癸二酸进行混合酯化反应，当物料逐步升温至210℃达到理论水量后，停止通氮气，逐渐升温到240℃，开始抽真空进行缩聚反应，直到取样分析酸值＞1,羟值＜25时,开始冷却出料；
步骤二、合成主剂：在反应釜中投入聚醚多元醇，异佛尔酮二异氰酸酯和催化剂，开始加热搅拌升温到80-130℃反应1.5h，开始抽真空1h后，然后冷却后50-60℃出料即得成品；
步骤三、合成固化剂：在反应釜中投入聚丁二烯醇，聚异氰酸酯(TPA-100)和催化剂，开始加热搅拌升温到85-95℃反应2h，然后冷却到50-60℃出料即得成品；
步骤四、合成胶粘剂：将主剂和固化剂按比例经加热搅拌混合，即可制得胶粘剂。
进一步的，所述步骤二合成的主剂的粘度范围设定在1700-2500mpa.s/25℃。
进一步的，所述步骤三合成的固化剂的粘度范围设定在800-1400mpa.s/25℃。
与现有技术相比，本发明的有益效果是：该无污染的无溶剂双组份聚氨酯胶黏剂及其制备方法既保持了溶剂而又能很好的进行涂布复合，用无溶剂胶粘剂干复合除具有使用溶剂型成本下降，没有有机溶剂挥发对环境的污染，不需要溶剂挥发干燥工段，降低了能耗，没有火灾、爆炸的危险，不再需要溶剂的防暴措施，也不再需要贮存溶剂的设备和库房，复合制品没有残留溶剂损害问题，并消除了溶剂对印刷油墨的侵袭。
