Abstract

This article presents the different flame retardant (FR) additives adapted to polypropylene (PP) and their mode of actions when incorporated into the bulk. PP is naturally highly flammable; this review highlights the challenges to improve its flame retardant properties. It first reports the thermal degradation of PP and then focuses on FR PP systems and shows the high flame retardancy effectiveness of intumescent flame retardant (IFR) systems providing an efficient protective layer. It also highlights the need to improve the IFR systems to reduce the amount of FRs, using synergists, bio-based compounds or modified additives, but also using other effective systems such as free radical generators systems in combination with phosphorous flame retardant agent. Therefore, this article explores the effectiveness of several FR systems and highlight their mechanism of action in PP.

聚丙烯阻燃剂：综述

本文介绍了适用于聚丙烯（PP）的各种阻燃（FR）添加剂，以及这些添加剂加入到聚丙烯中的作用模式。聚丙烯具有天然的高易燃性；本综述强调了改善其阻燃特性所面临的挑战。报告首先介绍了聚丙烯的热降解，然后重点介绍了阻燃聚丙烯系统，并展示了膨胀型阻燃剂（IFR）系统的高阻燃效果，该系统可提供有效的保护层。文章还强调了改进膨胀型阻燃剂系统以减少阻燃剂数量的必要性，不仅可以使用增效剂、生物基化合物或改性添加剂，还可以使用其他有效的系统，如与磷阻燃剂结合使用的自由基发生器系统。因此，本文探讨了几种阻燃剂系统的有效性，并重点介绍了它们在聚丙烯中的作用机理。

期刊介绍： Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology. Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal. However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
