摘要
通过试验对不同阻燃剂综合性价比进行比选,对不同掺配方式与比例下阻燃效果以及施工安全性进行试验,选用氢氧化铝作为阻燃剂确定掺配方式及比例。
Through the experiments of various flame retardants cost-effective integrated comparison,tested the effects and construction safety of flame retardants under different blending way and proportion.At last,we chosen aluminum hydroxide as flame retardant to determine blending mode and proportion.
