探讨辐射交联乙烯 醋酸乙烯酯共聚物 (EVA) /甲基乙烯基硅橡胶 (MVQ )复合绝缘子的配方和生产工艺。绝缘子的优化配方为 :EVA/MVQ (77～ 67) /(2 3～ 3 3 ) ;氢氧化铝 13～ 46;其它 1 3～ 3 9。成型采用模压工艺 ,模具的阴模温度为 70℃ ,阳模温度为 5 0℃ ,模压压力为 3 0MPa ,模压时间 (保压时间 )为 1 5～ 2min。辐射交联剂量不超过 2 0 0kGy。EVA/MVQ复合绝缘子可替代陶瓷绝缘子用于户外高压电器设备的绝缘器。
To investigate the formulation and production process of radiation cross-linked EVA / MVQ composite insulator. The optimal formulation of the insulator is: EVA / MVQ (77-67) / (2-3-3); aluminum hydroxide 13-46; others 1-3-3. Molding using molding process, the mold of the negative temperature of 70 ℃, the male mold temperature of 50 ℃, the molding pressure of 30MPa, molding time (dwell time) of 15 ~ 2min. Radiation cross-linking dose does not exceed 200kGy. EVA / MVQ composite insulator can replace ceramic insulators for outdoor high voltage electrical equipment insulators.
