摘　　要：采用新型纳米端羧基丁腈橡胶增韧改性酚醛树脂,通过傅立叶红外光谱(FTIR)、综合热分析(DTA-TG)等研究了改性树脂的界面反应和耐热性,研究表明,超细羧基丁腈橡胶表面存在大量的活性基团,可以与酚醛树脂发生相互作用,因此可以同时提高改性树脂的耐热性和冲击强度;力学性能研究表明采用改性树脂制备的树脂磨具的强度和韧性都得到提高,同时材料的硬度几乎不变,因此该树脂可广泛应用于精磨和抛光磨具中。A new nanometer carboxy terminated nitrile rubber was used to modify phenolic resin in this paper. The interface reaction and heat resistance of modified resin were studied with FTIR and DTA-TG. It showed that the surface of ultra-fine powdered acrylic rubber has many active groups, so it can joint with phenolic resin by molecular forces. Therefore modified resin with higher toughness and improved heat resistance can be obtained. At last, the strength and toughness of modified resin bonded abrasives were increased too, and it＇s hardness keep consistently, so it can be used in fine abrasive and abolishing.
