摘　　要：以蓖麻油、自制聚酯多元醇、聚醚多元醇和异氰酸酯等为主要原料,以硅烷偶联剂为添加剂,反应制备得到双组分无溶剂聚氨酯胶粘剂。研究异氰酸酯组分中异氰酸酯的种类对胶粘剂的本体拉伸强度、断裂伸长率、剥离强度、剪切强度等性能的影响。In this paper, the two-component solventless polyurethane adhesives was prepared with the castor oil, self-made polyester polyol, polyether polyol and isocyanates as the main raw materials and the silane coupling agent as the additive. And the effects of different type of isocyanates on the tensile strength, elongation at break, peeling strength and shear strength of the adhesive were studied.
