摘要
Abstract A macromolecular flame retardant was firstly the group reaction of DOPO-HQ. The modified polystyrene ADOPO-HQ-co-PS was prepared by copolymerization of macromolecular flame retardant and styrene. Its chemical structure was analyzed by Fourier transform infrared (FT-IR). PS composite was prepared by adding it to the experimental formula, and the cone-shaped calorimetry experiment was carried out on the material. The results show that it has a better flame retardant performance than DOPO-HQ. The smoke generation rate is very small, the highest is 0.2m 2 /s, the CO production is very small, the highest is 0.007g/s, and the mass loss is the highest is 0.14g/s, which shows that the material is more environmentally friendly and stable during combustion.
