General organophosphorous fire retardant mostly is liquid, has that molecular weight is little, polarity big, poor heat resistance, volatility are big, the amount of being fuming
Greatly and the poor compatibility of material, range of application migration little, easy, the shortcoming such as phosphorus content is low, fire resistance is poor.Therefore anxious on market
High comprehensive performance need to be developed, the organic phosphine fire retardant of disadvantages mentioned above can be overcome.Collaborative by ignition-proof elements many in structure or
Many fire retardants compound the effective way being to improve flame-retarded efficiency, and wherein the research to phosphorus, nitrogen synergistic fire retardant is to find excellent nothing
One of important research direction of halogen fire retardant.Due to the nitrogenous organic phosphine compound based on triazine ring derivatives have Halogen,
Low toxicity, decomposition temperature are high, fire retardant does not separates out, it is the most fire-retardant to give material and the feature such as machining property, by its with
Other fire retardant is compounding also can produce good synergistic function.Therefore, the research of this based flame retardant increasingly comes into one's own.
The invention discloses a kind of Triazinyl triphenyl isopropyl phosphinate fire retardant combination and application process thereof, this is fire-retardant
Triazinyl triphenyl isopropyl phosphinate in agent compositions contains C-P key and stable fragrant phosphine key, and Stability Analysis of Structures, possibly together with symmetry
Virtue-big conjugated system of phosphine-nitrogen and many ester structures, it has the preferable compatibility with material.By the difference in complex composition
Structure, multiple ignition-proof element produce synergistic function, and when burning, ignition-proof element phosphorus therein is readily formed densification and equal
Even polyphosphoric acid protecting film, element silicon promotes to form fine and close silicon-charcoal protective layer, and nitrogen element can play expansion, heat insulation anoxybiotic, fall
The multiple fire retardations such as temperature, show excellent flame-retarded efficiency.Fire retardant combination cooperative flame retardant is effective, with macromolecular material
Having the good compatibility, stability is high, is adapted to the high temperature process of material, does not reduce the mechanical strength of material.And this is fire-retardant
Agent preparation method of composition is simple, can reduce cost, have good application prospect.
