一种高固含量鞋用水性聚氨酯胶粘剂及其制备方法
摘要：
本发明涉及一种高固含量鞋用水性聚氨酯胶粘剂及其制备方法。其制备步骤为：制备含纳米氧化物的水性聚氨酯分散体；再将小分子多元胺滴加到水性聚氨酯分散体中进行扩链；最后加入质量比为0.01~0.2%的增稠剂和0.01~0.03%的消泡剂混合均匀；即得到高固含量鞋用水性聚氨酯胶粘剂。该水性聚氨酯胶粘剂具有固含量高、干燥速度快、耐水性十分优异的特点。
摘要（英）：

The invention relates to a high-solid content shoe waterborne polyurethane adhesive and a preparation method thereof. The preparation method comprises the following steps of: preparing a waterborne polyurethane dispersion containing a nano oxide; dropwise adding small-molecule polyamine into the waterborne polyurethane dispersion for chain extension; and finally, adding 0.01-0.2% of thickening agent and 0.01-0.03% of antifoaming agent both by mass and mixing uniformly to obtain the high-solid content shoe waterborne polyurethane adhesive. The waterborne polyurethane adhesive has the characteristics of high solid content, fast drying and remarkably excellent water resistance.
