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。
