摘要
提出了聚氯乙烯(PVC)抑烟的技术途径,概述了PVC用抑烟剂及其简要作用机理。用于PVC的主要抑烟剂有钼化合物、硼化合物、锡化合物和氧化锌-氧化镁配合物等,一般添加量为2～4phr可使PVC的生烟量降低30%以上,且能适度提高材料的阻燃性。
The authors put forwarded technical approaches for suppressing smoke emitted from the polyvinyl chloride （PVC） in burning and briefly summarized the smoke suppressants available for PVC and their action mechanism. Molybdenum compounds, boron compounds, tin compounds, and zinc oxide-magnesium oxide complex are usually deemed as the main smoke suppressants suitable for PVC. In general, adding 2-4 phr of one of the smoke suppressants can reduce the smoke generation by over 30% and therefore, considerably facilitate the improvement in flame retardance of the materials.
