What is the current status of the application of flame retardants?

Flame retardants are a class of functional additives, which are mainly used in the textile industry to change the burning properties of fabrics. According to the composition of flame retardants, flame retardants can be divided into halogen series, phosphorus series, nitrogen series, silicon series and so on. In recent years, the development of high-efficiency, low-smoke, low-toxic and dust-free flame retardants has become an important direction for the development of flame retardant science.

The flame retardants used in textiles of different materials are different. For cellulose fiber fabrics, the commonly used flame retardants are phosphorus-containing compounds, such as phosphorus oxide, ammonium polyphosphate, phosphorus heterocyclic compounds, and tetramethylol phosphorus chloride; The flame retardant for polyester fabrics is often a cyclic phosphate compound; the flame retardant commonly used for polyester-cotton blended fabrics is vinyl phosphate oligomer. Due to the excellent flame retardancy and environmental protection of boron-based flame retardants, they have also become one of the hot spots for development.

The new intumescent flame retardant was synthesized by a two-step method and applied to polyester fabrics with excellent flame retardant effect; nano-sized Mg(OH) 2 was prepared by hydrothermal method, and microcapsule flame retardant was prepared by in-situ polymerization method It improves the limiting oxygen index of cellulose fiber and makes the fiber have better flame retardant properties. With the continuous development of science and technology, flame retardants are developing rapidly towards microencapsulation, ultrafineness and compounding.Flame retardants are a class of functional additives, which are mainly used in the textile industry to change the burning properties of fabrics.
