摘要:
针对导爆药的塑料粘附性差而导致导爆管破孔率高及导爆管雷管易拒爆的现状，采用共混改性和分子定向迁移理论，通过配方优化，开发出一系列高药粉粘附性的导爆管专用塑料。根据导爆管传爆过程中对药粉粘附性的要求，确定了导爆药脱落率为16.0%的导爆管最佳专用塑料配方。试验表明：与常用牌号N210和1I2A制备的导爆管相比，高药粉粘附性导爆管震动后每15 m的破孔数由N210、1I2A制备时的4个、2个下降到0；50℃下每15m的破孔数由N210、1I2A制备时的4个、2个下降到0；雷管拒爆现象由N210、1I2A制备时的10%、6%下降到0。
Abstract:
Due to the bad adhesivity between explosive powder and shock tube, the shock tube tends to be broken and the shock detonator sometimes misfires. According to the theory of blending modification and oriented molecule migration, a series of special dedicated plastics for shock tube with high adhesivity were designed. For the need of adhesivity between explosive powder and shock tube during transmission, the best formula with 16.0% expulsion rate of explosive powder was determined. Experimental results showed that in contrast with conventional N210 and 1I2A counterparts, the highly adhesive shock tube has decreased the number of broken holes to 0 per 15m after shock (4 holes for N210 and 2 holes for 1I2A), broken holes at 50℃ to 0 per 15m (4 holes per 15m for N210 and 2 holes per 15m for 1I2A) and mifire rate of 0 (10% for N210 and 6% for 1I2A). 
