Flame Retardant Properties

AbstractA phosphorus-containing biphenyl-type phenolic resin (PBP) was prepared by dehydration polycondensation of the DOPO-disubstituted 4,4’- biphenyldimethanol compound (BDCA-2DOPO) with phenol in the presence of strong Lewis acid , in which BDCA-2DOPO was prepared by the reaction of DOPO with 4,4'-biphenyldicarboxaldehyde. The PBP resin has been evaluated as the curing agent of o-cresol epoxy resins. Experimental results indicated that the PBPcured epoxy resins exhibited good thermal stability, high char yields at 700 oC and outstanding flame retardant properties. UL 94 V-0 classifications could be obtained when the phosphorus loading in the epoxy resin is higher than 1.8 wt%.

The Stability

AbstractA hyperbranched phosphorus-containing copper phthalocyanine compound (DOPO-CuPc) was successfully synthesized and used as the flame-retardant additive to prepare flame-retarded epoxy thermosets. The addition of DOPO-CuPc led to a significant enhancement of the flame retardant properties of the epoxy resin. The 15DOPO-CuPc/EP composite obtained a LOI value of 35.8%, and the UL-94 rose from NR to V-0 rating. And the addition of DOPO-CuPc resulted in early decomposition of the epoxy thermoset, but the residual char at 700 °C reached 27.7%. The flame retardant mechanism was further investigated. It was found that DOPO-CuPc could release phosphorus-containing radicals and non-combustible gases in the gas phase to exert gas-phase flame retardant activity. In the condensed phase, the epoxy thermoset formed the expanded honeycomb-like char layer during combustion and the presence of copper phthalocyanine contributed to the stability of the char layer.
