Description

一种制卡复合材料用双组份胶黏剂及制备方法
技术领域
本发明属于制卡材料技术领域，尤其是一种制卡复合材料用双组份胶黏剂及制备方法。
背景技术
镭射膜一般采用计算机点阵光刻技术、3D真彩色全息技术、多重与动态成像技术等，经模压把具有彩虹动态、三维立体效果的全息图像转移到PET、BOPP、PVC或带涂层的基材上，故各种基材的激光镭射膜，在光线的照射下可呈现美丽的全息镭射光彩，随着光源的移动或观察点的变换，会产生变幻的镭射颜色图案，炫彩多目，豪华气派。将PET镭射膜铝面与PVC基材复合，复合型材的PET面印刷油墨后，制作的卡片具有高档、炫彩的装饰效果。目前，镭射膜与PVC基材中间采用复合胶进行粘合，传统的胶黏剂存在复合工艺受限，或粘接强度差等缺点，使制作的卡片镭射光彩不能完美呈现。
发明内容
本发明的目的在于克服现有技术的不足，提供一种粘接强度大、可冷复合且使用方便的制卡复合材料用双组份胶黏剂及制备方法。
本发明解决其技术问题是采取以下技术方案实现的：
一种制卡复合材料用双组份胶黏剂，由A组分和B组分组成，所述A组分构成组分及组分重量份数为：聚氨酯胶液50～80份，B组分构成组分及组分重量份数为：固化剂5～30份、助剂0.01～0.1份。
而且，所述聚氨酯胶液的构成组分及组分重量份数为：二异氰酸酯5～20份、聚合物二元醇60～90份、扩链剂1～5份、催化剂0.01～0.03份、有机溶剂100～200份。
而且，所述二异氰酸酯为甲苯二异氰酸酯、异佛尔酮二异氰酸酯、二苯基甲烷-4,4-二异氰酸酯、1,6-亚己基二异氰酸酯中的一种或多种。
而且，所述聚合物二元醇为聚醚二元醇、聚酯二元醇、聚己内酯二元醇、聚碳酸酯二元醇中的一种或多种，该聚合物二元醇的分子量为1000～4000。
而且，所述扩链剂为1,4-丁二醇、乙二醇、一缩二乙二醇、己二醇、二缩三乙二醇中的一种或多种；所述催化剂为二月桂酸二丁基锡或辛酸亚锡中的一种或多种；所述有机溶剂为异丙醇或乙酸乙酯中的一种或多种；所述固化剂为TDI固化剂、HDI固化剂、IPDI固化剂、MDI固化剂中的一种或多种；所述助剂为防霉剂AP24。
而且，所述固化剂的固含量为50～100％，NCO含量为5～25％。
一种制卡复合材料用双组份胶黏剂的制备方法，包括以下步骤：
⑴配制聚氨酯胶液：首先将异氰酸酯、聚合物二元醇、催化剂加入至装有搅拌器和回流冷凝管的反应釜中，混合均匀，在惰性气体环境下控温70～90℃反应1～3小时；然后，加入扩链剂，在60～80℃温度下反应1～2小时；最后，将上述预聚物降温至40℃以下，用有机溶剂稀释搅拌均匀，得到固含量为30～60％聚氨酯胶液；
⑵将聚氨酯胶液、固化剂和助剂混合均匀，以500r/min速度搅拌30～90min即可制得双组份胶黏剂成品。
本发明的优点和积极效果是：
本发明的双组份胶黏剂由聚氨酯胶液组分、固化剂及助剂组分构成，将其用于PET镭射膜铝面与PVC基材进行冷复合，经过55℃熟化48h用作制卡材料，操作简单、开放时间长、剥离强度大、粘结综合性能优良；复合材料镭射面光滑平整，无皱褶、橘皮效果，使制作的卡片镭射光彩完美呈现。
