Description

一种环保型水性聚氨酯胶黏剂的制备方法
技术领域
本发明涉及一种水性聚氨酯胶黏剂的制备方法，是一种环保型水性聚氨酯胶黏剂的制备方法。
背景技术
水性聚氨酯首次实现工业化生产是在1967年，其特点是原料丰富、无甲醛释放、无颜色污染，特别是胶合强度高，适合制造各类人造板材；缺点是干燥速度慢，初始粘性低，并且耐水性不佳，耐水性不佳的原因是由于水性聚氨酯本身含有亲水基团，所以要提高耐水性就要在保证乳液稳定的情况下，减少亲水基团的含量。
传统方法制备水性聚氨酯胶黏剂，没有考虑反应所残留的亲水基团，采用传统方法制备的水性聚氨酯胶黏剂，耐水性能欠佳，且贮存期短。在使用过程中因为其耐水性差限制了水性聚氨酯胶黏剂的发展。
发明内容
本发明的目的是克服现有技术的不足，提供一种粘接强度高，耐水性能好，无游离甲醛释放的环保型水性聚氨酯胶黏剂的制备方法。
实现本发明采用的技术方案是：一种环保型水性聚氨酯胶黏剂的制备方法，其特征是，它包括以下步骤，原料用量以质量份计，
1)将100份的聚醚多元醇加入到三口瓶中，在200～400r/min的速度下搅拌均匀，滴入20～25份的异氰酸酯，搅匀，升温至75℃，恒温反应1-2h；
2)取2～3份的扩链剂和0.1～0.6份的催化剂加入到步骤1)所述的三口瓶中充分搅拌，恒温反应3h，降温，将其倒入烧杯中，降至常温，加入1～2份的中和剂，搅拌10min，制成预聚体；
3)制备乳化水溶液：取乳化剂原液10份，加入100份水中加热溶解，待其水溶液呈透明且温度为常温，即制成乳化水溶液；
4)将乳化剂水溶液缓慢加入到步骤2)的预聚体溶液中，并在1500～2000r/min的速度下高速搅拌，搅拌时间10min，得到固含量在40％—50％的水性聚氨酯胶黏剂成品。
所述的聚醚多元醇为聚醚多元醇N220、聚丙二醇(PPG)和聚乙二醇(PEG)中的一种。
所述的异氰酸酯为甲苯二异氰酸酯(TDI)或二苯基甲烷二异氰酸酯(MDI)。
所述的扩链剂为二羟甲基丙酸(DMPA)、1,4-丁二醇(BDO)和三羟甲基丙烷中的一种；
所述的催化剂为二乙烯三胺、三乙烯二胺和二月桂酸二丁基锡中的一种。
所述的中和剂为三乙胺。
所述的乳化剂原液为丁二酸改性聚氧乙烯烷基酚醚(OS)或聚氧乙烯壬基酚醚(OP)中的一种。
本发明的一种环保型水性聚氨酯胶黏剂的制备方法与传统水性聚氨酯胶黏剂制备方法相比，具有以下优点：
①耐水性好；原因是对异氰酸酯基团的端部，进行封闭，不暴露其中的亲水基团，故其胶黏剂的耐水性较好；
②对多种材料有良好的粘接强度，异氰酸酯胶黏剂含有大量的极性基团和活性反应基团，能满足不同基材粘接和使用条件要求；
③大大地降低了其中未反应基团的含量，提高了使用时间；
④由于使用以水为分散剂，实现了无VOC释放，对环境的无污染，便于工业化生产；
⑤由于制备得到的产品是低黏度液体，使用方便，贮存期长、耐药品和耐大气老化性能高；
⑥适用范围广，在木材加工、包装、纺织、造纸、建筑、机械等多领域，可作胶黏剂、密封胶和涂料的原材料。
