摘　　要：传统的酚醛胶粘剂在高温下易分解、失去粘结强度,限制了其在高温工况下的应用。因此,开发一种能够在中温条件下固化且具备良好耐高温性能的改性酚醛胶粘剂就显得尤为重要。文章通过引入特定的改性剂对酚醛树脂进行改性,在中温固化的条件下获得耐高温性能优异的酚醛胶粘剂,深入分析探讨了其制备工艺及性能的影响因素。The traditional phenolic adhesive is easy to decompose and lose its bond strength at high temperature,which limits its application at high temperature.Therefore,it is particularly important to develop a modif ied phenolic adhesive that can cure at medium temperature and has good high temperature resistance.In this paper,the phenolic adhesive with excellent high temperature resistance was obtained by introducing a special modif ier to modify the phenolic resin under the condition of medium temperature curing.
