摘　　要：本文采用两步法,经过表面多层包覆改性及无机-有机多层包覆改性处理,制备出一种铝基复合阻燃剂,使其初始分解温度达到260℃以上,活化指数达到90%。有无毒、不产生腐蚀性气体、热稳定性好、不会产生二次污染、价格低廉等优点,可应用于热塑性树脂和热固性树脂,可直接、也可改性后与树脂混合,具有阻燃和抑烟双重功能。Composite aluminium base flame retardant has been prepared by the following two steps, surfacial multilayer coated and inorganic-organic multilayer coated modification. Primary thermal decomposition temperature of the retardant is up to or more than 260℃, and its active ratio is about 95 %. The flame retardant characterises in innocuity, good thermal stability , low price, and without erosive gas and secondary pollution. Therefore, the flame retardant can be mixed directly or after modification with thermoplastic resin and thermosetting resin to resist flame and suppress smoke.
