| 中文摘要: |
| 采用硫酸酸化高锰酸钾（KMnO4）溶液（H＋/KMnO4溶液）对氯丁橡胶（CR）（硫化胶）进行表面改性处理，研究KMnO4质量分数、pH值和温度对CR表面的性质、化学组成、粗糙度以及CR表面与阻燃涂层的粘合性能的影响。结果表明：H＋/KMnO4溶液处理的CR表面粗糙且生成大量含氧基团，CR表面与阻燃涂层的粘合性能提高；H＋/KMnO4溶液对CR表面处理的最佳条件为KMnO4质量分数 5%，pH值 1. 44，温度 60 ℃。 |
| 英文摘要: |
| The surface modification treatment of chloroprene rubber（CR）（vulcanizate） was carried out using sulfuric acid acidified potassium permanganate（KMnO4） solution（H＋/KMnO4 solution）.The effects of KMnO4 mass fraction，pH value，and temperature on the properties，chemical composition and roughness of CR surface and the adhesive property between CR surface and flame retardant coating were studied.The results showed that the CR surface treated with H＋/KMnO4 solution was rough and a large number of oxygen-containing groups were generated，which improved the adhesive property between CR surface and flame retardant coating.The optimal treatment conditions for CR surface with H＋/KMnO4 solution were KMnO4 mass fraction of 5%，pH value of 1.44 and temperature of 60 ℃. |
