The invention discloses a plastic-coated elastic low-smoke flame-retardant green environment-friendly elevator balance compensation chain, and relates to the technical field of elevator balance compensation chains, the plastic-coated elastic low-smoke flame-retardant green environment-friendly elevator balance compensation chain comprises an environment-friendly plastic-coated sheath, a metal closed-loop chain I and a polyvinyl chloride base material layer, the environment-friendly plastic-coated sheath comprises a polyvinyl chloride base material layer and a low-smoke flame-retardant structure, the fuming inhibitor layer is mounted on the outer side of the polyvinyl chloride base material layer, and the flame retardant layer is mounted on the outer side of the fuming inhibitor layer. The low-smoke flame-retardant structure is arranged on the outer side of the polyvinyl chloride base material layer, the flame retardant layer can form a barrier for blocking flames when the fireproof outer protection layer is burnt, flame spreading is inhibited, the burning speed is slowed down, smoke is reduced, and the service life of the fireproof outer protection layer is prolonged. The smoke generation inhibitor in the smoke generation inhibitor layer is used for reducing the amount of smoke released by the sheath material in the combustion process and adsorbing or neutralizing smoke particles generated in the combustion process, so that the concentration and toxicity of smoke are reduced, and the safety and reliability of the elevator are improved.
本发明公开了一种包塑弹性低发烟阻燃绿色环保型电梯平衡补偿链,涉及电梯平衡补偿链技术领域,包括环保包塑护套、金属闭环链条一和聚氯乙烯基材层,所述环保包塑护套包括聚氯乙烯基材层和低发烟阻燃结构,所述发烟抑制剂层安装在聚氯乙烯基材层的外侧,所述阻燃剂层安装在发烟抑制剂层的外侧。本发明通过在聚氯乙烯基材层的外侧设置有低发烟阻燃结构,阻燃剂层可以在耐火外保护层燃烧时形成一层阻挡火焰的屏障,抑制火焰的蔓延,从而减缓燃烧速度并减少烟雾的产生,发烟抑制剂层中的发烟抑制剂用于减少护套材料在燃烧过程中释放的烟雾量,吸附或中和燃烧过程中产生的烟雾颗粒,从而降低烟雾的浓度和毒性,提高了电梯的安全性和可靠性。
