Paper is divided into three chapters: Chapter : First of the wool flame retardant type , effects and development overview , and then expounded the research status of the flame - retardant wool , and finally explains the purpose, significance and conclusions of the research projects , references References 78 . Chapter II : fluorine potassium titanate and organic acid system , potassium zirconium fluoride and organic acid system , Fluotitanate inorganic salts wool fire-retardant treatment , thermal analysis, infrared spectroscopy , char yield , oxygen index of its fire-retardant properties and thermal degradation behavior was characterized . Comparison of the sample is not flame-retardant , flame-retardant wool has the following changes : ( a ) thermal degradation of the starting temperature is lowered ; oxygen index improver ( b ) ; ( c ) char yield increase ; ( d ) thermal degradation reduces the activation energy . Wool thermal degradation behavior on different systems at the same time to do a preliminary study , wool during pyrolysis , flame retardants wool catalytic decomposition , the decomposition of wool in advance , reducing the burning capacity of the wool , raise the limit oxygen index and char yield . The presence of an organic acid , a stabilizing effect of fluorine of potassium titanate fluorozirconate of Potassium Shared Fluotitanate and inorganic salts have a synergistic effect on the wool flame retardant The Chapter 3 : through a series of analytical methods TBPA and inorganic salts co-processing of flame retardant properties of wool were characterized , and, specifically, the thermal degradation behavior of the flame-retardant wool . Through the comparison processing with the untreated wool , flame-retardant and Thermodynamic Properties , that the flame retardants significantly improve the flame retardancy of wool , and the type of flame retardant mechanism and the influence on the of wool thermal degradation behavior makes a preliminary discussed. The TBPA work in the gas phase , generated in the thermal degradation of wool radical scavenger ( hydrogen bromide ) to prevent flaming combustion , reduce heat weightlessness , and inorganic salts in the solid phase work , catalytic decomposition of wool to improve the char yield .
