摘　　要：涂层阻燃简单高效,利用混料设计可高效快速优化阻燃涂料配方。以APP、MEL、PER和PU等为考察的阻燃涂料组分,以响应质量损失表征阻火性能、以背面最高温度表征涂层处理后的隔热性能,应用混料设计建立组分配比与响应的数学模型,以优化水性膨胀型阻燃涂料配方。建立了质量损失和背面最高温度模型,方差分析显示该模型,信噪比高。利用模型得到6种优化配方。优化配方不一定唯一,其中较理想的配方为APP∶MEL∶PER∶PU=0.321∶0.130∶0.149∶0.400(质量百分比),并通过试验验证。该研究表明混料设计优化水性阻燃涂料配方高效、可行。Retardant coating is a simple and effective method to improve flame ratardance, and it is efficient to optimize formulation of coating with mixture design. Four components including Ammonium polyphosphate （APP）, melamine （MEL）, pentaerythritol （PER）, and water-brone polyurethane （PU） were chosen, the response quality loss was used to characterize the properties of fire resistance and the back maximum temperature was used to characterize the thermal insulation properties after coating. The mathematical models between the response and component proportion were built up to optimize formulations by using mixture design method. The model between quality loss and the back maximum temperature was set up the ANOVA results showed that the model had a significance effect, high goodness of fit, and high ratio of signal/noise the models had advantages of good fitting degree and high signal-noise ratio. Six set of optimized formulations were obtained by using the models, of them, the ideal formula was APP ： MEL ： PER ： PU=0.321 ： 0.130 ： 0.149 ： 0.400 （mass fraction）, which were verified through the experiments. Thus, it is proved that the optimal water-brone intumescent flame retardant coating by mixture design is efficiency and feasible.
