| 摘 要： | 为提高竹材液化产物所制备的高轻发泡墙体材料的防火性能，分别采用材料内部添加和表面浸泡的方法进行阻燃改性，并评价不同阻燃剂及其添加量对发泡材料阻燃性能的影响。实验结果表明：在材料内部或表面添加选择的阻燃剂不会对材料自身形貌或组分产生明显影响，对材料的力学性能亦不会造成破坏，在材料内部添加3 g膨胀型凝胶-二氧化硅/聚磷酸铵核壳阻燃剂（MCAPP）后压缩强度达到了0.37 MPa，在材料表面浸泡聚硅氧烷后压缩强度达到了0.58 MPa，同时能提高材料的阻燃性能，在材料内部添加聚磷酸铵（M-APP）后极限氧指数提高到33.2%，比改性前提高3%。在材料表面浸泡膨胀型壳聚糖-蒙脱土-聚磷酸铵（CMAp）后点燃时间明显延长，极限氧指数最高达到了31.5%。 |

| Abstract: | In order to improve the fireproof performance of the high-light foam wall materials prepared by the bamboo material liquefaction products, various methods of internal addition and surface immersion were used to carry out a variety of flame retardant modifications, and the effects of different flame retardants and their additions on the foam materials were evaluated. The expenmental effect of flame retardancy. The experimental results show that: adding the selected flame retardant inside or on the surface of the material will not have a significant impact on the morphology or composition of the material itself, and will not cause damage to the mechanical properties of the material. After adding 3 g of expanded gel-silica/ammonium polyphosphate core-shell flame retardant(MCAPP) inside the material, the compressive strength reached 0.37 MPa. The compressive strength after immersing the surface of the material with oxane reaches 0.58 MPa. At the same time, it can improve the flame retardance of the material. The limiting oxygen index increased to 33.2% after adding ammonium polyphosphate(M-APP) inside the material, which was 3% higher than before modification. After immersing the expanded chitosan-montmorillonite-ammonium polyphosphate(CMAp). The flame retardant was soaked on the surface of the material, the ignition time was significantly prolonged, and the limiting oxygen index reached 31.5%. |
