| Abstract: | The preparation method of halogen-free intumescent flame retardant PP/EVA cable compound was introduced.The cable compound was characterized by means of limited oxygen index(LOI)、 UL94 vertical combustion cabin,electronic universal testing machine and thermogravimetric analysis (TG) test.The results indicated that the oxygen index was increased to 34.5%,and the burning grading was reached to UL94 V0;the tensile strength was 15.11MPa and the elongation at break was 557.67% ;then the char yield was 17.49% at 600℃. |
