摘要
论述了由端羟基聚醚、多异氰酸酯等组成的单组分聚氨酯胶粘剂的制备及其在汽车引擎盖上以粘代焊加工的应用。该胶中加入了一种特殊的固化剂、它在温度低于80 C时不参与固化反应、一旦温度高于80 C则快速固化。因而,在施胶后短时间内即可转入下道工序,这就极大地缩短了生产周期,提高了生产效率。
One-component polyurethane adhesives prepared by using polyisocyanate and polyether are applided to the production of engine cover in automobile. Here, bonding is used instead of shot-welding. A special curing agent, which cannot act if temperature is below 80 C while curing quickly above 80C, has been added in the preparation, which leads to the results of cutting down the opertion cycle and raising the efficiency remarkably.
