模压成型法PVG阻燃整芯输送带覆盖胶的配方优化
|
摘要
对模压成型法PVG阻燃整芯输送带[由聚氯乙烯树脂(PVC)阻燃整芯输送带表面贴合橡胶型覆盖胶制成]覆盖胶进行配方优化。覆盖胶优化配方为:丁腈橡胶100,PVC(糊状) 30,炭黑N234 40,硬脂酸2,氧化锌5,氯化石蜡/三氧化二锑/硼酸锌/聚磷酸铵/氢氧化铝20/8/15/15/15,分散剂R50 5,增塑剂20,防老剂2,硫黄/促进剂TBBS1.7/1.8。优化配方覆盖胶与带芯粘合性能、物理性能、阻燃性能和滚筒摩擦试验结果达到MT 914—2008要求。
The formulation of the covering compound of PVG flame-retardant integral core conveyor belt which was made of PVC flame-retardant integral core conveyor belt with a covering compound by molding method was optimized. The optimum formulation of the covering compound was as follows:NBR100,PVC(paste) 30,carbon black N234 40,stearic acid 2,zinc oxide 5,chlorinated paraffin/antimony trioxide/zinc borate/ammonium polyphosphate/aluminium hydroxide 20/8/15/15/15,dispersant R50 5,plasticizer 20,antioxidant 2,and sulfur/accelerator TBBS 1. 7/1. 8. The adhesion between the covering compound and the core,the physical properties,flame-retardant performance and drum friction test results of the optimized covering compound met the requirements of MT 914—2008.
