Composite Flame Retardant, Give You New Ideas of Flame Retardant!

At present, domestic research and development mainly focuses on inorganic flame retardants, red phosphorus microcapsules, intumescent flame retardants and other fields. Resin- and rubber-based composites contain a large number of organic compounds, which have a certain degree of combustibility. Flame retardants are a class of additives that prevent polymeric materials from catching fire or inhibit the spread of flame. The most commonly used and important flame retardants are compounds of phosphorus, bromine, chlorine, antimony and aluminum.

Flame retardants can be divided into two categories according to the method of use: additive and reactive. Flame retardants mainly include phosphate esters, halogenated hydrocarbons, antimony oxide, etc. They are mixed into composite materials during the processing of composite materials, which are easy to use and adaptable, but affect the performance of composite materials. Reactive flame retardants are added to the polymerization system as monomeric raw materials in the polymer preparation process, and mixed with polymer molecular chains through chemical reactions, so they have little effect on the performance and fire resistance of the composite material durable. Reactive flame retardants mainly include phosphorus-containing polyols and halogenated anhydrides.
