【摘要】 本文基于氧指数自熄性、油毡流淌时间、油毡烧穿时间、成本分析来确定阻燃改性沥青油毡的配比，借助红外光谱和差热－热失重对阻燃机理进行了研究，提出了相应的结论。更多还原

【Abstract】 On the basis of self-extinguishing of Oxygen index, fluidifying time of asphalt felt, burn-through time of asphalt felt and cost analysis, the article fixes the pro portion ratio of uninflammable modified asphalt felt. It also researches on the uninflammability mechanism by means of infrared spectrum and differential heat-heat weightlessness. then submits relevant conclusion.更多还原
