摘　　要：研究不同种类的松香和活性剂的热分解失重情况,考察它们在焊接过程中的稳定性和分解失重产生气体的情况.结果表明:不同种类的松香和活性剂的热稳定性不同,其中RAX最为稳定,在260℃下长时间不分解;有机酸相对稳定;卤代物稳定性最差,能够完全分解;不同种类的有机胺氢卤酸盐的稳定性差别较大.This study is focused on the thermal decomposition performance of different kinds of rosin and activators,specifically their stability and decomposition weightlessness in the welding process.The results indicate that different kinds of rosin and activators have different thermal stability,wherein the RAX is the most stable and does not decompose at 260 ℃ for a long time.The stability of organic acids is relatively stable,while the halide completely decomposes and therefore is most unstable.In a word,different kinds of organic amine halogen acid salt have great difference in decomposition performance.
