Abstract

In order to enhance the low smoke halogen-free flame retardant properties of ethylene vinyl acetate copolymer (EVA) based composite materials while maintaining or improving their mechanical properties, a study was conducted to synthesize a phosphorus-nitrogen compound (OT) containing double bonds using oleylamine (OA) and amino trimethylene phosphonic acid (ATMP) as raw materials, and then introduce it into the ethylene-vinyl acetate copolymer/magnesium hydroxide (EVA/MH) blend composite system through melt blending. The structure and properties of the OT and EVA/MH composite materials were tested and characterized using a Fourier transform infrared spectrometer (FTIR), a scanning electron microscope (SEM), a rotational rheometer, a differential scanning calorimeter (DSC), a universal testing machine and a limiting oxygen index (LOI) tester. The results show that the introduction of OT optimizes the cross-linking structure of the material and prevents the breakage of the molecular chains. OT promotes the dispersion of MH within the polymer matrix, aids in the crystallization of EVA, and notably enhances the flame-retardant and mechanical characteristics of the material. The composites display a tensile strength of 13.8 MPa, an elongation at break of 432%, and an LOI of 39.0% with the addition of 2 phr of OT, demonstrating their outstanding flame retardant and mechanical properties.
