| 摘 要： | 采用聚醚多元醇、聚合二苯基甲烷二异氰酸酯(PAPI)为主要原料制备了木材用单组分湿固化聚氨酯胶黏剂。研究了-NCO含量、聚醚多元醇相对分子质量、反应温度及扩链系数对木材粘接性能的影响。结果表明:在-NCO质量分数为12.29%,扩链系数为0.2时,粘接性能最好,24 h后压缩剪切强度可达20.17MPa。

| Abstract: | One-component moisture-curable polyurethane adhesive for wood was prepared by using polyether polyols and polymethylenepolyphenylisocyanate(PAPI) as main materials.The effects of-NCO content,the average relative molecular mass of polyether polyols,the reacion temperature and the chain extending coefficient on adhesion strength of the adhesive for wood were studied.The results show that moisture-curable polyurethane adhesive has the best adhesion property when-NCO mass fraction is 12.29% and the chain extending coefficient is 0.2.The compression shear strength is 20.17MPa after 24h. |
