摘　　要：以酸和溶剂为主剂制备了系列铁路机车腻子剥离剂,研究了组分组成、浸泡时间和温度等条件对不饱和聚酯腻子质量保留率和压缩强度保留率的影响。结果表明:基于硝酸制备的腻子剥离剂去除效果更优,室温浸渍时间20~30 min后,腻子质量保留率最低为51.8%,压缩强度保留率最低为9.2%。Series of putty stripping agent used for locomotive were prepared based on acids and solvents. The effect of compositions, soaking time and temperature on the quality and strength retention ratios were studied. The results showed that stripping agent prepared from nitric acid was more effective compared with that from formic acid. With the putty soaking at room temperature for 20~30 min, the lowest quality retention ratio was 51.8% and the lowest compress strength retention ratio was 9.2%.
