An ideal flame retardant can satisfy those conditions

According to the relationship between the flame retardant and the flame retardant, the flame retardant can be divided into additive type and reactive type. The former is only physically dispersed in the substrate and is mostly used in thermoplastic polymers. The latter, as a monomer or auxiliary reagent, participates in the synthesis of polymers, and then becomes the structural unit of polymers, mostly used for thermosetting polymers.

According to the fire-retardant elements, the commonly used fire retardants are divided into halogen system, organic phosphorus system and halogen phosphorus system, nitrogen system, phosphorus nitrogen system, antimony system, aluminum magnesium system, inorganic phosphorus system, boron system, silicon system, molybdenum system, etc. There are also a kind of intumescent flame retardant and a kind of nano inorganic material. The latter can form flame retardant polymer inorganic nano composite material with a series of polymers.

With the expansion of the application of polymer composite materials and the increase of its dosage, the application of flame-retardant materials and flame-retardant technology have also made some progress. Phosphorus flame retardants have been widely used for their wide variety and excellent flame retardancy. In the future, the research of phosphorus flame retardants should be more inclined to the development direction of flame retardants with high thermal stability and good solubility.

Flame retardant is a kind of assistant used to prevent materials from being ignited and flame propagation. It is mainly used in flame retardant synthesis and natural polymer materials. It is an indispensable chemical material in our life. Since the organic synthetic polymer materials are widely used, human beings begin to face a new fire threat. At present, the form of global fire is very severe. Therefore, flame retardant is particularly important as a chemical additive.

It is worth noting that an ideal flame retardant can meet the above conditions, but it is almost impossible. Therefore, when choosing practical flame retardants, most of them meet the basic requirements, compromise and get a good comprehensive balance among other requirements.

Now, people are increasingly aware that the use of flame retardant materials is one of the strategic measures to prevent and reduce fire, which has been proved by the practice of some countries. There is no doubt that the research, production and application of flame retardants and flame retardant materials are important measures related to "environment and human beings", and "flame retardants" will be accepted by more and more people.
