An efficient oligomeric charring agent (CNCA-DA) containing a triazine and benzene rings was synthesized and characterized by the NMR spectroscopy (13C solid-state NMR), elemental anal. (EA) and thermal gravimetric anal. (TGA). The synergistic effects between ammonium polyphosphate (APP) and CNCA-DA on the flame retardancy, thermal degradation and flame retardant mechanism of low d. polyethylene (LDPE) were investigated. The thermogravimetric anal. (TGA) and thermogravimetric analyzer coupled to a mass spectrometer (TGA/MS) results indicated that IFR could reduce the thermal degradation rate at main stage of degradation and side chain fragmentation was probably the dominant mechanism of thermal degradation The cone calorimeter test (CCT) results demonstrated that IFR clearly changed the decomposition behavior of LDPE and formed an intumescent char layer on the surface of the composites, subsequently resulting in the efficient reduction of the flammability parameters, such as the heat release rate (HRR), total heat release (THR), smoke production rate (SPR), total smoke production (TSP), mass loss (ML), CO production (COP) and CO2 production (CO2P). The Fourier-transform IR spectroscopy (FTIR), laser Raman spectroscopy anal. (LRS) anal. results revealed that an appropriate graphitization degree and network structure of the residue char were formed to improve the strength and shield properties of the char layer to obtain better flame retardant properties of the composite. This study involved multiple reactions and reactants, such as 4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4COA of Formula: C9H6Cl2N4).
4,6-Dichloro-N-phenyl-1,3,5-triazin-2-amine (cas: 2272-40-4) belongs to organic chlorides. Organic chlorides can be used in production of: PVC, pesticides, chloromethane, teflon, insulators. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.COA of Formula: C9H6Cl2N4
