Polymer flame retardant is a hot spot and heavy research area in recent years. This kind of flame retardant has the characteristics of easy dispersion, good compatibility and little influence on mechanical properties of materials, and has a good application prospect. This paper is inspired by this, the traditional melamine flame retardant modified by polymer, to produce polymerized melamine flame retardant, which has the advantages of traditional flame retardant and polymer flame retardant, can effectively improve the flame retardant performance and mechanical properties of the material.

People are vigorously developing and popularizing flame retardant, and they are also reflecting on it. Especially in Europe and America, effective action has been started in this regard, which has certain standards for the types and contents of flame retardant in consumer goods. In the beginning stage, more and more attention has been paid to the rational and safe use of flame retardant.

In this regard, we need to remind relevant enterprises: first, we should pay attention to the trend of the laws and regulations of the use of flame retardant for foreign consumer goods, accurately grasp the laws and regulations, and organize production in strict accordance with the requirements of the exporting countries. Second, strictly control the inspection, improve the raw material risk verification procedure, and establish a system of access and audit for qualified suppliers of high-risk raw materials. Third, it has the spirit of exploration, and develops and uses better raw materials to replace some unreasonable materials.

In modern science, four new flame retardant agents of high nitrogen and phosphorus have been synthesized from melamine, polyformaldehyde, cyanuric acid, polyphosphate, phosphoric acid and boric acid: polymerized melamine cyanurate PMCA, polymerized melamine cyanophosphate PMPP, polymerized melamine phosphonate PMP and polymerized melamine cyanoacrylate PMB, The optimum synthetic conditions were discussed and determined during the synthesis.
