UV curable acrylic PSAs (pressure-sensitive adhesives) were modified with organic and inorganic flame retardants to improve flame retardancy of PSAs minimize the sacrifice of adhesion properties. The flame retardancy (UL-94 test) of acrylic PSAs were enhanced by the addition of 5-30 wt % of an organic flame retardant such as TCEP (Tris(2-chloroethyl)phosphate), PBPE (pentabromophenyl ether), and TBBPA(3,3 0 5,5 0 -tetrabromobisphenol A). Especially, TBBPA is the best flame retardant for acrylic PSAs when it works alone. However, PSAs compounded with aluminum trihydroxide (Al(OH) 3 ) showed a little reduction in burning time up to 30 wt %. An apparent synergic effect was observed only for an acrylic PSAs with a combination of TCEP and PBPE flame retardants. The addition of flame retardants brought a no significant effect on curing even in high amount. It was surmised that the miscibility between PSAs and flame retardant was closely related with flame retardancy and adhesion properties of acrylic PSAs.

“…Moreover, the density of antimony halide is higher than that of air, which can act as a barrier to oxygen. BAFR has the advantages of high ame retarded e ciency, relatively low lost, outstanding thermal stability and uidity, and especially less in uence on the mechanical properties of matrix, which is the earliest developed ame retardants and also one of the most widely used ame retardants for polymeric materials [4][5][6] . Although there is some different opinion, the comprehensive ame retardant effect of BAFR is still the best for most polymers [5,6] among all ame retardants.…”

Aiming at developing a non-antimony synergistic agent of BFR and improving the high heat and smoke release of BFR due to its gaseous phase flame retardant mechanism, CeHPP was synthesized through hydrothermal reflux method and introduced into PC/DBDPO through melt blending. The morphology, chemical structure and thermal stability of CeHPP were characterized through SEM, FTIT and TG analysis, while the flame retardancy of PC/DBDPO/Sb2O3 and PC/DBDPO/CeHPP composites were compared and discussed in detail. To our delight, CeHPP showed more excellent synergistic effect with DBDPO than Sb2O3 in PC matrix. For PC/DBDPO/CeHPP (92/7/1, wt%), the sample was not ignited, the value of limited oxygen index (LOI) went up to 39.2% and it reached UL 94 V0 rating in vertical burning test, while the Izod impact strength, elongation at break and Young’s modulus were almost kept same with those of pure PC. Moreover, according to the cone calorimetry, CeHPP and DBDPO/CeHPP could efficiently suppress the heat and smoke release of PC composites, while DBDPO and DBDPO/Sb2O3 would accelerate the heat and smoke release during combustion The synergistic flame retardant mechanism verified that the char-barrier effect of CeHPP transferred the free-radical-trapping effect of BFRs from the gaseous phase to the condensed phase, which interfered the chain oxidation reaction of free-radicals and inhibiting the release and spread of gases and smoke.
