| titleOfInvention | Flame retardant and preparation method thereof |
| abstract | The invention relates to a flame retardant and a preparation method thereof, and PAN-DCD and metal oxyacid are reacted to prepare the flame retardant, wherein the PAN-DCD is a product prepared by taking polyacrylonitrile and dicyandiamide as raw materials, and the structural formula is as follows: wherein w is an integer of 10 or more, and k, m, n, p and q are integers of 1 or more; the structural formula of the finally prepared flame retardant is as follows: wherein w is an integer of 10 or more, k, m, n, p and q are integers of 1 or more, A ‑ Ions formed after giving protons to the metal oxo acids. The preparation method has the characteristics of easily obtained raw materials, simple and easy process, short flow, short production period of products, safe production operation and the like, and the finally prepared flame retardant has the characteristics of good thermal stability, high flame retardant efficiency, low solubility, good compatibility with polymers, excellent char formation property, excellent comprehensive performance and the like, can realize green and environment-friendly production, and has extremely high popularization value. |
