主要介绍了无机阻燃剂、有机阻燃剂和复合型阻燃剂改性的聚氯乙烯(PVC),以及这些阻燃剂对PVC阻燃性能的影响.其中无机阻燃剂的阻燃效果最为明显,不过消烟效果较差;有机阻燃剂消烟效果较为明显,但阻燃能力不如无机阻燃剂;复合型阻燃剂兼具有机/无机阻燃剂的优点,或具有多种无机阻燃剂的优点,一般既具有较强的阻燃能力,又具有较为显著的消烟效果,是未来PVC用阻燃剂的发展方向.%Polyvinyl chloride (PVC) modified by inorganic flame retardants,organic flame retardants and composite flame retardants was introduced. The flame-retardant effect of inorganic flame retardants is most obvious,but its smoke suppressing effect is poor. Organic flame retardants show better smoke suppressing effect,but the flame retardant ability is poorer than inorganic flame retardant. Composite flame retardant,which possess both advantages of organic and inorganic flame retardant or the advantages of several inorganic flame retardant,not only exhibit excellent flame retardant ability,but also promise smoke suppressing effect. It is the future development direction of the flame retardant of PVC.
