Preparation and property of novel halogen-free flame retardant ABS by P-N blendable flame retardant packages
With styrene-butadiene-acrylonitrile (ABS) as subtstrate resins, by adding resorcin bis(diphenyl phosphate) (SOL-DP ) condensation polymer and melamine cyanurate ( MCA) blendable system as flame retardant packages, we prepared halogen-free flame retardant ABS composities and studied its mechanical properties and combustion performance. The test results showed that, when the effective content of SOL-DP and MCA in the base ABS resin reached 8％ and 4％ respectively, the mechanical properties of the samples maintained about 90％, and LOI values reached as high as 27.5, meanwhile, the samples achieved a V0 UL-94 reading as might have been expected. SOL-DP with MCA can promote char formation and prevent the combustion behavior of the ABS effectively. When SOLDP and MCA blends total content amount to 15％ in base ABS, heat release rate and total heat release rate has dropped significantly, such as the maximum heat release rate dropped to 70％.
