水性凹印油墨用水性聚酮改性聚氨酯乳液及其制备方法和 应用
技术领域
本发明属于水性聚氨酯技术领域，具体涉及一种水性凹印油墨用水性聚酮改性聚氨酯乳液及其制备方法和应用。
背景技术
在环保意识逐渐增强的今天，水性油墨因其不含挥发性有机溶剂、越来越受到人们的青睐。目前，国内包装薄膜的印刷主要采取凹印方式，其承印物主要有PET、BOPP、NY薄膜等，因此在薄膜凹印中使用水性油墨已成为一种必然的趋势。
水性凹印油墨的附着力即水性油墨与承印薄膜表面之间通过物理/化学作用相互粘结及吸引的能力，水性凹印油墨中的成膜树脂是影响水性凹印油墨的附着力的主要因素之一。传统的水性聚氨酯油墨对PET薄膜具有较好的附着力，但是对BOPP薄膜几乎没有附着力，即使BOPP薄膜经过电晕处理，水性聚氨酯油墨对其也几乎没有附着力。
因此研究一种水性油墨用的水性聚氨酯树脂乳液，以使得该水性油墨对经过电晕处理的BOPP薄膜具有优异的附着力，就显得尤为重要。
发明内容
本发明的目的是克服现有技术的不足而提供一种水性凹印油墨用水性聚酮改性聚氨酯乳液及其制备方法和应用，该水性聚酮改性聚氨酯乳液可以赋予水性油墨优异的附着力，尤其使得水性油墨与经过电晕处理的BOPP薄膜具有优异的附着力。
本发明采用如下技术方案：
水性凹印油墨用水性聚酮改性聚氨酯乳液，包括按照质量百分比计的如下组分：水性聚氨酯乳液77％-85％，水性聚酮乳液15％-23％；
所述水性聚氨酯乳液由如下组分制备而得：含双键结构的多元醇、二异氰酸酯单体、羧基二醇类亲水扩链剂、非离子二醇类亲水扩链剂、成盐剂、氨基磺酸盐类亲水扩链剂、二胺类扩链剂、酮类溶剂、水，所述端羟基聚丁二烯、二异氰酸酯单体、羧基二醇类亲水扩链剂、非离子亲水扩链剂、成盐剂、氨基磺酸盐类亲水扩链剂、二胺类扩链剂、酮类溶剂及水的质量比为(13-18)：(6-10)：(1.3-3.3)：(0.7-1.8)：(2.8-5.5)：(0.6-1.5)：(0.75-1.5)：(25-40)：(45-55)；
所述水性聚酮乳液由如下组分制备而得：质量分数为50％的聚酮树脂的丁酮溶液、异氟尔酮二异氰酸酯(IPDI)、丙酮、质量分数为90％的二胺磺酸钠水溶液(PPS)、水，其中所述质量分数为50％的聚酮树脂的丁酮溶液、异氟尔酮二异氰酸酯、丙酮、质量分数为90％的二胺磺酸钠水溶液和水的质量比为200：69.8：45：67.5：232。
其中二胺磺酸钠的化学结构式如下：
Figure BDA0001743028330000021
更进一步地，所述含双键结构的多元醇为羟值在(45-101)mgKOH/g的端羟基聚丁二烯。
更进一步地，所述二异氰酸酯单体为异氟尔酮二异氰酸酯(IPDI)、4.4’-二环己基甲烷二异氰酸酯(HMDI)或甲苯二异氰酸酯(TDI)。
更进一步地，所述羧基二醇类亲水扩链剂为二羟甲基丙酸(DMPA)或二羟甲基丁酸(DMBA)。
更进一步地，所述非离子二醇类亲水扩链剂为YermerTM N120(瑞典(Perstorp)柏斯拖公司生产)(分子量为1000g/moL，羟值为110mgKOH/g)，非离子二醇类亲水扩链剂的结构式如下：
Figure BDA0001743028330000022
更进一步地，所述成盐剂为质量分数为20％的KOH的乙醇溶液，传统使用的成盐剂因使用胺类成盐剂，味道较重，因此采用质量分数为20％不含有胺味的KOH的乙醇溶液作为成盐剂，在使用时不会有刺鼻气味。
更进一步地，所述氨基磺酸盐类亲水扩链剂为固含量为90％的二胺磺酸钠PPS(分子量：550g/mol)水溶液。
更进一步地，所述二胺类扩链剂为异氟尔酮二胺(IPD)或乙二胺，所述酮类溶剂为丙酮或丁酮；所述聚酮树脂的羟值：220mgKOH/g。

步骤二，水性聚酮乳液的制备：按照所述质量配比，取质量分数为50％的聚酮树脂的丁酮溶液，升温至50-60℃，加入异氟尔酮二异氰酸酯，升温至75-85℃，反应4.5-5.5h，待NCO基团的百分含量达到3.85-4％时，降温至35-45℃，加入丙酮搅拌均匀，加入固含量为90％的二胺磺酸钠水溶液，反应25-35min，加入水乳化50-70min，真空脱除丁酮和丙酮，即得水性聚酮乳液；
步骤三，混合：将上述所得水性聚氨酯乳液和水性聚酮乳液按照所述质量配比混合均匀，即得所述水性凹印油墨用水性聚酮改性聚氨酯乳液。
所述水性凹印油墨用水性聚酮改性聚氨酯乳液在水性油墨中的应用，具体如下：按照质量份数计，将30-40份水性凹印油墨用水性聚酮改性聚氨酯乳液、2-4份分散剂、0.2-0.6份消泡剂、1-2份润湿流平剂、0.3-0.8份pH调节剂、5-8份异丙醇、8-10份乙醇、18-25份水和10-16份颜料，经搅拌分散、研磨、过滤，制得水性凹印油墨。

步骤二，水性聚酮乳液的制备：按照所述质量配比，取质量分数为50%的聚酮树脂的丁酮溶液，升温至50-60℃，加入异氟尔酮二异氰酸酯，升温至75-85℃，反应4.5-5.5h，待NCO基团的百分含量达到3.85-4%时，降温至35-45℃，加入丙酮搅拌均匀，加入固含量为90%的二胺磺酸钠水溶液，反应25-35min，加入水乳化50-70min，真空脱除丁酮和丙酮，即得水性聚酮乳液；
步骤三，混合：将上述所得水性聚氨酯乳液和水性聚酮乳液按照所述质量配比混合均匀，即得所述水性凹印油墨用水性聚酮改性聚氨酯乳液。
9.权利要求1所述水性凹印油墨用水性聚酮改性聚氨酯乳液在水性油墨中的应用，其特征在于，具体如下：按照质量份数计，将30-40份水性凹印油墨用水性聚酮改性聚氨酯乳液、2-4份分散剂、0.2-0.6份消泡剂、1-2份润湿流平剂、0.3-0.8份pH调节剂、5-8份异丙醇、8-10份乙醇、18-25份水、10-16份颜料，经搅拌分散、研磨、过滤，制得水性凹印油墨。
