Flame retardant plasticizer
Phosphate ester as flame retardant occupies an important position in polymer flame retardant application. The flame retardant plasticizer for soft PVC is mainly a variety of aromatic phosphate and aryl - alkyl phosphate. All of the phosphatates used as soft PVC flame retardant plasticizer were similar to that of 7.8% ~ 8.6%. They are used to replace some phthalates and other esters plasticizers in soft PVC, which can improve the flame retardancy of the products, but other performance deteriorates.
With the literature, three aryl phosphate ester flame retardant PVC with high oxygen index and the elastic modulus, and the alkyl aryl phosphate ester flame retardant PVC two oxygen index and elastic modulus are relatively low, this is because many aryl phosphate ester flame retardant high and low flexibility. Moreover, the alkyl substituents on aryl group have an effect on the flame retardancy and softness of phosphate ester. The time of flame retardant PVC is relatively short, and the difference is not very large. Between 10 and 20 seconds, this is because the phosphate ester is more volatile and the thermal cracking at lower temperature.
In addition, K.S.Annakutty et al. studied the effect of polyphosphate on the flame retardant of soft PVC. Results show that the PVC/butyl phthalate (DBP)/low molecular mass of phosphate ester (including all kinds of phosphate, triethyl phosphate teb, three toluene phosphate ester TCP) (50/40/10), the presence of phosphate, can promote the PVC into carbon, and carbon rate increased with the increase of the phosphorus content increases. But there is no big difference in the heat loss data of PVC containing various polyphosphate.
Thermo-gravimetric experiment shows that the teb, TCP behavior and make PVC containing phosphate ester of PVC is different, more basic won't promote PVC into charcoal, at 550 ℃ of PVC will be weightless. In addition, compared with TEP and TCP, the presence of polyphosphate can inhibit the thermal oxidation degradation of PVC more effectively. Most of the sample's oxygen index is between 25 and 27. Compared with PVC containing monophosphate, PVC with polyphosphate has better flame retardancy.
In the comparison of PVC with different polyphosphate ester, the oxygen index is higher when the polyphosphate contains the halogen. The flame retardant effect of alkyl polyphosphate on PVC is also better than that of aromatic phosphate ester. In addition, antimony trioxide (Sb2O3) is not suitable for PVC with plasticized phosphate. There are reports that such a recipe would lead to the opposite synergism, reducing the flame retardancy of the system.

After adding DAP, ATH and polymer flame retardant packing (FRP), the oxygen index can be increased from 24.5 to 27.5. But the poor stability of the flame retardant plasticizer, will happen in 80 ℃ decomposition, so only a small number of alternative DOP in use.
Polybrominated polymer quality alkyl benzene flame retardant plasticizer. Conventional flame retardants have a flame retardant effect on system, but because it may to a certain extent affect the other performance of the resin, with people also want to find a better flame retardants, as small as possible impact on resin. In 1991, there were patent reports that polybrominated macromolecular high quality alkyl benzene flame retardant plasticizer was used to plasticize PVC.
Polybrominated polymer quality alkyl benzene as the flame retardant type plasticizer with PVC resin has the advantages of flame retardant, non-volatilization and resistance to migration. For halogenated resins such as PVC, this flame retardant plasticizer is very effective. The higher the bromine content of the polybrominated macromolecules, the less smoke is produced in the combustion. At the same time, the high bromine content also benefits the thermal stability of the system.
