Description
技术领域
本发明涉及聚氨酯技术领域，尤其涉及一种工艺品礼盒包装上的水性涂用喷胶及其制备方法。
背景技术
随着现代人们生活水平的不断提高，人们对包装盒的需求量也在不断增加。商品包装盒在市场营销过程中占据有重要的角色，其用自己特有的形象语言与消费者进行沟通从而影响着消费者，其中，纸制包装盒是包装工业品中用量最大的种类。
纸制包装盒的加工过程中一般需要用到黏结剂，水性聚氨酯胶粘剂具有软硬度可调节、柔韧性好、无毒无污染及机械性能好等优点，能粘接金属、非金属等多种材料，被广泛应用于工艺品等纸制礼盒包装加工中。但是目前水性聚氨酯喷胶存在干燥不够快、耐水解性能不佳等缺陷。
发明内容
基于背景技术存在的技术问题，本发明提出了一种工艺品礼盒包装上的水性涂用喷胶及其制备方法。
本发明提出的一种工艺品礼盒包装上的水性涂用喷胶，其原料按重量份包括：甲苯二异氰酸酯16-24份、降冰片烷二异氰酸酯7-12份、蓖麻油5-12份、聚醚多元醇55-68份、甲基丙烯酸酯3-7份、一缩二乙二醇3-7份、二羟甲基丙酸0.5-2份、季戊四醇0.5-1.5份、催化剂0.2-0.6份、稳泡剂0.5-2份、防老化剂0.2-1份。
优选地，所述聚醚多元醇由聚丙二醇和聚氧化丙烯三醇按照2-3：2-3的重量比组成；优选地，聚丙二醇的分子量为1000-2000，聚氧化丙烯三醇的分子量为3000-3500。
优选地，所述催化剂为有机锡催化剂；优选地，为二月桂酸二丁基锡、辛酸亚锡、二乙酸二丁基锡中的一种。
优选地，所述稳泡剂为烷基醇酰胺。
优选地，所述防老化剂是由抗氧剂1010和紫外吸收剂UV-1229按照3-5：2-3的重量比组成的。
本发明还提出了上述工艺品礼盒包装上的水性涂用喷胶的制备方法，包括以下步骤：
S1、对甲苯二异氰酸酯、降冰片烷二异氰酸酯、蓖麻油、聚醚多元醇进行脱水处理；
S2、将蓖麻油、聚醚多元醇加入到反应容器中，然后加入甲苯二异氰酸酯、降冰片烷二异氰酸酯、甲基丙烯酸酯和催化剂，升温反应，然后加入一缩二乙二醇和二羟甲基丙酸，搅拌反应，再加入季戊四醇和丙酮，搅拌反应，降至室温，加入三乙胺中和反应体系；
S3、向S2的反应体系中加入稳泡剂、防老化剂，乳化分散，减压蒸馏除去丙酮，即得水性聚氨酯涂用喷胶。
优选地，S2中，将蓖麻油、聚醚多元醇加入到反应容器中，然后加入甲苯二异氰酸酯、降冰片烷二异氰酸酯、甲基丙烯酸酯和催化剂，升温至70-80℃反应2-3h，然后加入一缩二乙二醇和二羟甲基丙酸，搅拌反应1-2h，再加入季戊四醇和丙酮，搅拌反应30-40min，降至室温。
