摘要
为获得阻燃聚甲基丙烯酸丁酯包覆材料,进行了ZrO2和磷酸三甲苯酯(TCP)改进聚甲基丙烯酸丁酯阻燃性能的研究。结果表明,ZrO2和TCP的不同添加总量、ZrO2与TCP的配比对其协同效果都有影响。当ZrO2/TCP的添加量为10%(质量分数)、配比为3∶7(质量比,下同)时,材料的氧指数达到24.6,协同效果最佳。采用热分析、数码照相、拉曼光谱和红外光谱等对成炭机理和协同效应进行了分析。结果表明,当ZrO2/TCP协效体系的总质量分数为10%、配比为3∶7时,500℃时体系的成炭量为14.7%,ZrO能通过催化和交联作用而影响成炭量和炭层结构。
A study of improving the flame retardancy property of polybutyl methacrylate （PBA） by ZrO2 and tricresylphosphate （TCP） was carried out. The results showed that both the amount of two additives and ZrO2/ TCP ratios influenced the synergistic effect. When the amount of ZrO2 and TCP was 10% （mass fraction） and the ratio of ZrO2/TCP was 3 ： 7, the OI of PBA composite could reach 24. 6 and the best synergistic effect was obtained. The carbonization mechanism and synergistic effects were studied by thermal gravimetric analysis （TGA）, digital photos, Raman spectra and Fourier transform infrared spectra （FTIR）. The results showed that when the amount of ZrO2 and TCP was 10% （mass fraction） and the ratio of ZrO2/TCP was 3 ： 7, the char yield of PBA composite at 500℃ was 14.7%. The results also provide evidences that ZrO2 can influence the structure of char layer by catalyzing and crosslinking.
