New flame retardant system blank? Complicity in the pursuit of synergies – flame retardant, the market trends – Fire Industry
Recent years, the world has not developed a fundamental new flame retardant system. However, the research team from around the world to promote the existing
Flame Retardant Or to the development of halogen-free system has made great progress.
Although the reaction mechanism of coordination has not been fully mastered, but prepared by synergistic reaction flame retardant additives and multifunctional systems become more and more popular and likely to become an important feature of the future development of flame retardants . In flame retardant technology, synergies not only produce more effective flame retardant system, and allows reduction of other flame retardants in the use of chemicals possible, and can improve the flame retardant efficiency and flame retardant to meet the increasingly stringent standards of production and use to make a positive contribution.
Many minerals and organic halogen flame retardants and organic phosphorus flame retardant has a synergistic effect. Borate and hydrated minerals in the composition of the thermosetting material can also be observed synergy hair. The inorganic mineral filler added to the expansion
Fireproof materials Can better control the fire after the expansion of material in contact with the structure of the flame shape. More and more experience has shown that, despite the apparent price of inorganic mineral fillers are increasing, but in fact, add the appropriate inorganic mineral fillers, flame retardants can be reduced by a large number of other additives, or by providing multi-functional activity performance to reduce production costs .
Currently, the most important compounds are synergistic flame retardant antimony oxide and halogen donor compounds. Metal oxides and other metal compounds are also promising prospect, especially used in engineering thermoplastics. Flame retardant technology, another important direction of development of new antimony trioxide is mixed granulation, as synergistic flame retardants. Antimony oxide mixture forms a single component fire retardant system and the advantages of masterbatch. Antimony compounds, the cost of relatively inexpensive, has a large number of used flame retardant. However, antimony is a toxic material, its use in most countries are constrained by the relevant laws and regulations, so there is a gradually replace or reduce the use of antimony compounds, the trend of flame retardants. However, co-halogen flame retardants and antimony compounds have very good synergy, especially for plasticizing PVC resin. Non-halogen flame retardant polymers in order to obtain a certain performance, need to mix a suitable bromine or chlorine compounds.
Antimony compounds in a number of alternative systems, the most potential advantage is zinc sulfide. Up to now, only ZnS was considered to be used as a pigment. Zinc sulfide coordination compounds, alone or as a new type of flame retardants have been around.
The melamine added to the inorganic mineral filler flame retardant composite was prepared, then the composite flame retardant polypropylene mix of people, usually to improve flame retardant UL94 flame test behavior, while eliminating inorganic mineral filler alone generated afterglow phenomenon. This can reduce the flame retardant polypropylene compound quality, which can generate economic benefits; also allows the use of relatively low cost of inert filler, such as high territory, and talc, which alone did not show when the flame retardant properties.
Recent years, the world has not developed a fundamental new flame retardant system. However, the research team from around the world in the promotion of existing flame retardants to halogen-free system development has achieved great progress.
Although the reaction mechanism of coordination has not been fully mastered, but the response prepared by synergistic flame retardant additives and flame retardant system is becoming increasingly popular multi-function, and likely to become an important feature of the future development of flame retardants .
