Abstract

The invention discloses a double base compound based on phosphonitrile and triazine group. A preparation method of the double base compound comprises the following steps: introducing a triazine group into phosphonitrilic chloride trimer with intrinsically flame retardant property, and substituting six chlorine atoms on the side chains; further introducing a compound containing diamido or dyhydroxyl into the side chains of the triazine group, so as to obtain the double base compound based on phosphonitrile and triazine group. The compound is enriched in elements N and P; because the compound simultaneously contains the phosphonitrile and triazine group, the compound can achieve a flame-retardant effect in the combustion process by virtue of gas phase flame retardance and condensed phase mechanisms and has an excellent char-forming effect, and the generated carbon layer has the effects of insulating heat and inhibiting oxygen and achieves the effects of intumescent flame retardants. In addition, the phosphonitrile and triazine group have a synergistic flame retardant effect in the matrix combustion process. Moreover, the compound is high in heat stability, char-forming rate and processability and can be widely applied to flame-retardant modification of various high polymer materials.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a flame retardant and a preparation method thereof, in particular to a double-radical compound based on phosphazene and triazine groups and a preparation method thereof. Background technique [0002] Triazine compounds have become the focus of research because of their excellent char-forming properties, easy-to-react molecular characteristics and relatively low price. As early as 1990, CipolliR et al used triazine compounds and phosphides to construct self-extinguishing thermoplastic polymers or elastomers. In 2006, Li Bin et al. optimized the synthesis process of triazine and invented a triazine oligomer containing hydroxyl and diamine groups and applied it to polyolefins. Since then, people have continuously optimized and improved the structure of triazine compounds, and designed and synthesized a series of triazine derivatives. For example, triazine macromolecular co...
