Description

一种改性聚氨酯胶粘剂
技术领域
本发明涉及聚氨酯胶粘剂技术领域，尤其涉及一种改性聚氨酯胶粘剂。
背景技术
聚氨酯胶粘剂因其具有良好的综合性性能和性能可调节性，而广泛应用于建筑、汽车、家庭装潢、包装、印刷、皮革、工艺品等的粘结。目前，聚氨酯胶粘剂从使用体系不同分为溶剂型、无溶剂型和水性聚氨酯胶粘剂。溶剂型聚氨酯胶粘剂具有污染环境、固含量低的缺点，另外涂胶工艺吋对操作人员有很大的危害。无溶剂型聚氨酯胶粘剂在国内发展刚刚开始，其合成工艺复杂，目前得到的性能还不能和溶剂型聚氨酯胶粘剂相比，仍需大力发展。水性聚氨酯胶粘剂以水为分散介质，具有环保、无毒、涂胶使用期长、节省资源等优点，但目前的水性聚氨酯溶剂存在粘结性不足等问题，亟待解决。
发明内容
基于背景技术存在的问题，本发明提出了一种改性聚氨酯胶粘剂，本发明润湿性和粘结性能优异。
本发明提出了一种改性聚氨酯胶粘剂，按重量份包括：改性聚氨酯乳液50-70份、邻苯二甲酸二丁酯0.5-1.5份、抗氧化剂168 0.1-0.3份、丙烯酸酯型流平剂0.01-0.08份、有机硅类高效消泡剂Tego901W 0.002-0.01份、水性固化剂0.5-3份、润湿剂Wet500 0.5-1.2份、甲基异噻唑啉酮0.05-0.09份、二月桂酸二丁基锡0.001-0.004份。
优选地，所述改性聚氨酯乳液的制备方法为：按重量份向三口瓶中加入60-100份混合多元醇，在温度为50-55℃下真空脱水2-3h；待冷却至45℃，加入3-6份2,2-二羟甲基丙酸和25-45份和4，4'-二苯基甲烷二异氰酸酯，搅匀，控制温度在73-77℃，保温反应1.5-2.5h；然后加入1-5份1,4-丁二醇扩链1-1.8h，再加入10-25份环氧树脂和15-35份松香进行改性，反应2-4h，反应过程中视体系黏度的大小加入适量丙酮，待体系冷却至室温，在高速搅拌下加入三乙胺水溶液中和、乳化，即得改性聚氨酯乳液。
优选地，所述混合多元醇由聚醚二元醇、聚酯二元醇和蓖麻油按质量比1:1-4:0.5-1组成。
优选地，所述的改性聚氨酯胶粘剂，按重量份包括：改性聚氨酯乳液55-65份、邻苯二甲酸二丁酯0.8-1.3份、抗氧化剂168 0.15-0.25份、丙烯酸酯型流平剂0.02-0.06份、有机硅类高效消泡剂Tego901W 0.004-0.008份、水性固化剂1-2.5份、润湿剂Wet500 0.7-1.1份、甲基异噻唑啉酮0.06-0.08份、二月桂酸二丁基锡0.002-0.003份。
本发明用环氧树脂和松香对聚氨酯进行改性，由于环氧树脂是双酚A型的多羟基化合物，一方面，环氧基和羟基通过反应将交联点引入聚氨酯主链，提高了聚氨酯的交联密度，另一方面，其所含的双酚A结构大大增加了聚氨酯刚性；松香中主要组成是树脂酸，而树脂酸是具有三环菲骨架的含有两个双键的一元羧酸，它与聚氨酯有良好的相容性，可增加胶粘剂的初粘性、润湿性、塑性等；另一方面，松香中的羧基由于连于叔碳原子上，有较大的空间位阻，故其反应活性低，在有羟基或水存在条件下，不会与NCO反应，但容易和胺发生反应，形成盐，在体系中可起乳化剂的作用；以松香与环氧树脂改性聚氨酯，既能降低聚氨酯分子的内聚力，又能改善体系润湿性和粘结性。另外，多元醇是水性聚氨酯胶粘剂的软段部分，其类型对胶粘剂性能有重大影响，本发明中以合适的比例将聚醚二元醇、聚酯二元醇和蓖麻油组成混合多元醇，其中，聚醚二元醇主链中含有醚键结构单元，属于柔性链，而且醚键不易水解，故合成的胶粘剂具有较好的柔软性、耐水解性能；聚酯二元醇主链中酯键极性大，有利于提高水性聚氨酯胶粘剂的内聚能和粘接力，并使胶粘剂的耐热性、耐油性和初粘强度均较好；蓖麻油也是一种多元醇，其优点是可以有效提高聚氨酯胶粘剂的交联密度，并且蓖麻油价格低廉、来源丰富且具有可再生性，有利于环保和经济效益的提高。
