摘要：

通过熔融法将PBS和DOPO/g-C₃N₄混合，制备了PBS/DOPO/g-C₃N₄共混复合材料，采用氧指数仪、红外光谱仪、高级旋转流变仪等对复合材料性能进行研究.结果表明：随着体系中DOPO/g-C₃N₄质量分数的增大，氧指数由22提升至25以上，垂直燃烧等级由无等级提升至V-1、V-0等级，可见DOPO/g-C₃N₄的加入提高了PBS的阻燃性能；当PBS中加入DOPO/g-C₃N₄后，复合熔体由剪切变稀转变为剪切变稠，复合熔体属于典型的非牛顿流体，随着温度升高，其表观黏度变小；PBS/DOPO/g-C₃N₄熔体的非牛顿指数随着DOPO/g-C₃N₄质量分数的增加而提高，当DOPO/g-C₃N₄质量分数为10％时，非牛顿指数趋近于1.0.

Abstract:

PBS/DOPO/g-C₃N₄blend composites were prepared by mixing polybutylene succinate (PBS) and DOPO/g-C₃N₄through melting method. The properties of the composites were studied by oxygen index instrument, infrared spectrometer and advanced rotational rheometer. The results showed that as the mass fraction of DOPO/g-C₃N₄in the system increased,the oxygen index increased from 22 to above 25, and the vertical combustion grade increased from non-grade to V-1 and V-0 grades. It can be seen that the addition of DOPO/g-C₃N₄ improved the flame retardant performance of PBS,with DOPO/g-C₃N₄ being added to PBS, the composite melt changed from shear thinning to shear thickening. The composite melt was a typical non-Newtonian fluid. The apparent viscosity deceased as the temperature increased. The non-Newtonian index of the PBS/DOPO/g-C₃N₄melt also increased with DOPO/g-C₃N₄ being introduced into the system. The non-Newtonian index approached to 1.0 when the ratio of DOPO/g-C₃N₄was 10%.
