将海泡石(SEP)和聚磷酸铵(APP)同时加到聚氯乙烯(PVC)/竹粉复合材料中,考察SEP和APP对复合材料的协效阻燃抑烟作用及力学性能的影响。结果表明,在锥形量热实验中,热释放速率峰值相对减少42.8%,平均热释放速率和总热释放量相对减少29.5%和25.7%,总烟释放量相对降低了12.2%,一氧化碳平均产率相对降低了42.0%;扫描电子显微镜分析发现,APP具有催化成炭并形成膨胀泡沫炭层的作用,而SEP具有吸附聚集诱导成炭,的作用;APP的阻燃机理主要属于气相阻燃机理,SEP的阻燃机理主要属于凝聚相阻燃机理;弯曲性能测试结果表明,SEP与APP对PVC/竹粉复合材料具有协同颗粒增强作用;拉伸性能测试结果表明,SEP对PVC/竹粉...

The effects of sepiolite (SEP) and ammonium polyphosphate (APP) on synergistic effects of flame retardant and smoke suppression and mechanical properties of polyvinyl chloride (PVC)/ bamboo powder composites were investigated by add-ing SEP and APP. The results of the cone calorimeter experiment show that the peak heat release rate decreases by 42.8% relatively, the average heat release rate by 29.5% relatively and total heat release by 25.7% relatively,compared by a relative decrease of 12.2% in total smoke production and of 42.0% in the average yield of carbon monoxide.
