| 中文摘要: |
| 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。 |
| 英文摘要: |
| 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：NBR 100，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. |
