Description
技术领域
本发明属于聚氨酯粘合剂技术领域,尤其涉及一种过滤嘴用聚氨酯粘合剂及其制备方法和应用。
背景技术
卷烟过滤嘴对降焦减害、改善吸味,提高卷烟品位起到很大作用,是卷烟生产过程中不可缺少的一部分。现有香烟过滤嘴材料主要为醋酸纤维素和聚丙烯,其中,醋酸纤维素滤材的过滤和吸附性能优异,而聚丙烯滤材制造成本低,由于聚丙烯是非极性材料,纤维的粘合成型需要专门的粘合剂;现有的醋酸纤维素以及聚丙烯丝束大都是不可降解的。
现有技术中,也有采用聚乳酸丝束制作卷烟过滤嘴。聚乳酸是以淀粉基农作物经过发酵得到的乳酸为原料,再经过聚合反应过程生成的高分子树脂。聚乳酸具有良好的生物降解性,使用后能被自然界中微生物完全降解,用它制成烟用聚乳酸丝束,具有原料可再生、滤棒过滤性能优异、废弃可完全生物降解等优点。然而,聚乳酸丝束制作过滤嘴时,其力学性能通常难以满足高品质,特别是加入粘合剂后。
公布号为CN 101805583 A的中国专利文献公开了一种聚乳酸卷烟丝束用可降解粘合剂,该专利文献中,使用可生物降解的多元醇作为聚氨酯的羟基单体,制备出可生物降解、易甩胶的水性聚氨酯粘合剂。尽管该粘合剂具有可生物降解性,具有一定的粘结性,但该粘合剂的耐久性、热稳定性不足,在粘接强度方面表现不如传统的非降解粘合剂,易出现脱胶或断裂问题,特别是耐高温高湿性能差,在高温环境下(如香烟抽吸时)易失去粘接性能,这将导致滤嘴材料散落或脱落,影响过滤嘴的烟气过滤性能。
发明内容
有鉴于此,本发明提供一种过滤嘴用聚氨酯粘合剂及其制备方法和应用,本发明提供的聚氨酯粘合剂具有高粘性,耐高温高湿性好,利于在制备过滤嘴滤材中的应用。

本发明提供如前文所述的过滤嘴用聚氨酯粘合剂在制备卷烟过滤嘴中的应用。
与现有技术相比,本发明通过预聚合、中和成盐、分散及扩链三个阶段,制成过滤嘴用聚氨酯粘合剂;本发明采用一定比例可生物降解的羟基单体,以及功能单体、亲水单体和异氰酸酯单体,在溶剂中逐步聚合反应,生成聚氨酯预聚体,所述功能单体为含丙烯酰基官能团的酯类单体,所述亲水单体为含羟基羧酸、取代磺酸盐和醇胺中的一种或多种。本发明改进了原料配方,不仅聚氨酯预聚体中引入了特定功能单体,而且扩链时引入增强剂,通过单体等配方优化,提高粘合剂高温高湿环境下的粘结性能、稳定性能。
此外,本发明预聚反应时,可提高反应温度、延长反应时间,如温度调控在91~95℃,反应时间为4-6小时,确保充分的聚合反应,增加反应速率和粘合剂分子量。本发明制备工艺上优选提高反应温度、延长反应时间,选择更合适的聚合反应条件,通过精确控制反应条件,获得更高分子量的聚氨酯预聚体,从而提高粘接强度和耐久性。
进一步地,本发明的分散和扩链阶段,优选加入了由纳米二氧化硅、纳米氧化铝、纤维素材料组成的增强剂,增加粘合剂的强度和稳定性,提供额外的机械支撑、增加界面粘附力、热稳定性和湿度阻隔性能,从而显著改善粘接性能。

对比例1
以实施例3为参照,预聚体中不加入功能单体,分散扩链阶段不加入增强剂,其余均与实施例3相同。

对比例3
以实施例3为参照,分散扩链阶段不加入增强剂,其余均与实施例3相同。
实施例6

实施例7
以实施例3为参照,控制反应温度为约70℃,水浴加热反应约2小时得预聚物,其余均与实施例3相同。
性能测试
对实施例1-7以及对比例1-3所得产品进行性能测试,测试方法如下:
粘度:Brookfield LV 25℃测试。
拉伸剪切强度参照GB/T 7124-86,聚乳酸材料作为粘接材料,分别测试常温下的拉伸剪切强度,以及高温高湿环境下的拉伸剪切强度(80%湿度、120℃条件下放置24小时测试);粘结性能主要由拉伸剪切强度体现。
固化时间测试:往聚乳酸纤维上涂覆适量聚氨酯胶黏剂(聚氨酯胶粘剂涂层约5mm),记录胶层表面黏性消失的时间(min),判断标准以不粘手即可。
表3产品性能测试结果
由表3可知,实施例1-5均具有较好的性能,更好地满足应用需求,其中实施例3为最优实施例,常温和高温拉伸剪切强度最好,固化时间最短,产品的粘度也满足要求(粘度低利于涂胶机施工)。
相比实施例3,对比例1不加入功能单体,不加入增强剂,常温和高温拉伸剪切强度效果基本最差。
相比实施例3,对比例2不加入功能单体、对比例3不加增强剂,常温和高温拉伸剪切强度也明显变差。实施例6加的增强剂不是三者混配,实施例7反应时间较短,两者粘度较低,而常温和高温拉伸剪切强度有所降低。
由以上实施例可知,本发明方案不仅聚氨酯预聚体中引入了特定功能单体,而且扩链时引入增强剂,通过单体等配方优化,提高粘合剂高温高湿环境下的粘结性能、稳定性能,从而解决现有聚氨酯粘合剂用于过滤嘴滤材时,粘接强度低、热稳定性不足,尤其是耐高温高湿性能差的问题。
以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明进行若干改进和修饰,这些改进和修饰也落入本发明权利要求的保护范围内。
