Polyurethane adhesive as well as preparation method and application thereof
The invention provides a polyurethane adhesive, which is composed of isocyanate, a polyether polyol composition, a solvent, a coupling agent, an antioxidant and a light stabilizer, and based on the total weight of the polyurethane adhesive, the polyurethane adhesive comprises the following components by weight: 20-60 wt% of isocyanate, 24-65 wt% of a polyether polyol composition, 5-25 wt% of a solvent, 0.5-2.5 wt% of a coupling agent, 0.05-0.55 wt% of an antioxidant and 0.1-0.5 wt% of a light stabilizer. And 0.1-1% by weight of a light stabilizer. The polyurethane adhesive provided by the invention solves the problems of high-temperature rutting and low-temperature embrittlement of an asphalt pavement, and meanwhile, the production process of a mixture is relatively simple, the operable time is long, and the water-resistant stability is good.
本发明提供了一种聚氨酯胶粘剂，其由异氰酸酯、聚醚多元醇组合物、溶剂、偶联剂、抗氧剂和光稳定剂组成，其中，基于所述聚氨酯胶粘剂的总重量，各组分按重量计为：异氰酸酯20‑60wt％，聚醚多元醇组合物24‑65wt％，溶剂5‑25wt％，偶联剂0.5‑2.5wt％，抗氧剂0.05‑0.55wt％，光稳定剂0.1‑1％wt％。本发明的聚氨酯胶粘剂解决了沥青类铺装路面的高温车辙、低温脆裂的问题，同时使得混合料的生产工艺相对简单、可操作时间长且耐水稳定性良好。
