| Abstract: |
| The effects of the preparation and the addition level of flame retarder on the properties of flame retardant EPDM/PP TPV were investigated.The results showed that an EPDM/PP TPV with better flame retardance and somewhat poorer physical properties was obtained by using the blending flame retardant system of decabromo-diphenyl oxide (FR-10)/antimony trioxide (Sb2O3) adding the flame retarder before dynamic vulcanization，and an EPDM/NBR TPV with better flame retardance and lower tensile strength was obtained by adding high level of flame retarder；and an EPDM/PP TPV with a little better flame retardance and somewhat poorer physical properties and extrudate appearance was obtained by using the blending flame retardant system of FR-10/Sb2O3/magnesium hydroxide[Mg(OH)2]and adding Mg(OH)2 before dynamic vulcanization，and the addition level of Mg(OH)2 had little effect on the flame retardance of EPDM/NBR TPV.A flame retardant EPDM/NBR TPV with low hardness and smoke emission was obtained by using blending flame retardant system of FR-10/Sb2O3/Mg(OH)2 and adding Mg(OH)2 before dynamic vulcanization. |
