由于近年来PP、HIPS、ABS三类塑料已大量应用于制作电子、电器部件,故我们重点研究这三类树脂的阻燃及应用。本文针对这三类树脂的阻燃机理,阻燃剂的筛选、协同效应及应用研究等作一简要的介绍。一、阻燃机理 PP、HIPS、ABS作为热塑性塑料均是一种极易燃烧的碳氢结构的高聚物,其燃烧性能参数如表1。塑料的燃烧主要经历四个阶段: 受热→分解→着火→燃烧 In recent years, PP, HIPS, ABS three types of plastics have been widely used in the production of electronic and electrical components, so we focus on the three types of resin flame retardant and applications. In this paper, the flame retardant mechanism of these three resins, flame retardant screening, synergistic effect and application of a brief introduction. First, the flame retardant mechanism PP, HIPS, ABS as a thermoplastic is a highly combustible hydrocarbon structure of the polymer, the combustion performance parameters in Table 1. The main combustion of plastics through four stages: heat → decomposition → ignition → combustion
