摘要
以缩短酚醛树脂固化时间为目的,使用纳米氧化铝为催化剂,丁腈橡胶为增韧剂,AlCl3络合物为固化促进剂,制备了一种能够快速固化的酚醛树脂胶黏剂。通过固化时间、DSC、TG和力学性能等测试,结果表明,当加入15%丁腈橡胶和2%AlCl3络合物时,酚醛树脂胶黏剂的增韧效果和固化速度均为最佳,可在180℃下20min内实现快速固化,同时具有优异的耐热性能和力学性能。
To reduce the curing time of phenol-formaldehyde resin, using nano-alumina as catalyst, nitrile rubber as toughening agent and AlCl3 complex compounds as curing accelerator, then the fast-curing phenol-formaldehyde resin adhesive was prepared. By the results of curing time, DSC, TG and mechanical properties test, it was shown that when added 15% nitrile rubber and 2% AlCl3 complex compounds, the fast-curing phenol-formaldehyde resin adhesive could be cured with excellent heat resistance and mechanical properties at 180℃within 20min.
