According to the different components, inorganic salt flame retardants, organic flame retardants and organic and inorganic mixed flame retardants can be classified.
Inorganic flame retardant is the most widely used flame retardant at present. Its main component is inorganic. The main products are aluminum hydroxide, magnesium hydroxide, monoammonium phosphate, diammonium phosphate, ammonium chloride, boric acid, etc. .
The main component of the organic flame retardant is organic matter, and the main products are halogen, phosphate, halogenated phosphate and the like. There is also a part of organic flame retardant used for durable flame retardant finishing of textile fabrics, such as hexabromohydroxide aqueous dispersion, decabromo-ruthenium trioxide flame retardant system, which has good flame retardant resistance to washing.
The organic and inorganic mixed flame retardant is an improved product of an inorganic salt flame retardant, and mainly uses an aqueous emulsion of a water-insoluble organic phosphate to partially replace the inorganic salt flame retardant. Among the three types of flame retardants, inorganic flame retardants have the advantages of non-toxic, harmless, smokeless and halogen-free, and are widely used in various fields. The total demand accounts for more than half of the total demand for flame retardants, and the demand grows. The rate has a growing trend.
