摘　　要：研究蛋壳(CES)废料作为环保生物填料的膨胀型阻燃涂料的性能。将聚磷酸铵II、季戊四醇和三聚氰胺与阻燃填料和丙烯酸树脂黏合剂混合,制成膨胀型阻燃涂料,进行火焰表面扩散试验、火焰蔓延试验、热重分析试验、粘结强度试验等测试涂料的防火性能。结果表明,试件B、C、D、E在火焰下暴露时均未显示出火焰表面扩散。在涂料B、E中添加质量分数为5.0%、2.5%的蛋壳生物填料,由于炭化而改善了防火性能。试件D、E的总火焰传播指数分别为4.5、5.0,显示出优良的阻燃性能。防火涂料具有良好的耐水性、热稳定性和粘结强度,具有良好的防火性能。The performance of eggshell(CES)as an innovative environmentally friendly biofiller intumescent flame retardant coating was studied.Three flame retardant additives,namely ammonium polyphosphate II,pentaerythritol and melamine,were mixed with flame retardant filler and acrylic resin binder to make the intumescent flame retardant coating.The fire performance of the coating was tested by flame surface diffusion test,flame spread test,thermogravimetric analysis test and bond strength test.The test results showed that the test pieces of B,C,D and E did not show flame surface diffusion when exposed to flame.Eggshell biofillers with a mass fraction of 5.0%and 2.5%were added to coatings B and E,respectively,which improved fire resistance due to charring.The total flame propagation indices of the test pieces D and E were 4.5 and 5.0,respectively,showing excellent flame retardancy.The fire retardant coating has good water resistance,thermal stability and bond strength,and has good fireproof performance.
