摘要：In this paper, stearic acid, titanate coupling agent (NDZ-311) and silane coupling agent (KH-570) were selected as modifiers to modify colemanite powder and the resulted products were characterized by XRD and FT-IR. The results show that the surfaces of colemanite particles were effectively modified by stearic acid and coupling agents. The modified colemanite /EVA composites were then prepared and the effect of coupling agent addition on the mechanical properties and flame retardancy of EVA composites was investigated. The EVA composite doped with 40% of modified colemanite (coupling agent accounting for 1% of colemanite mass) exhibits a tensile strength of 9.80MPa, a breaking elongation of 696.5% and a limit oxygen index of 29.6%. The complex flame retardant was obtained by means of grafting amine polyphosphate onto the surface of colemanite using polyphosphoric acid (PPA) and laurylamine as raw materials. The obtained product was analyzed by XRD and FT-IR. The EVA composite doped with 40% of the complex flame retardant has a tensile strength of 8.57MPa, a breaking elongation of 671.3% and a limit oxygen index of 32.6%. ? 2016 Trans Tech Publications, Switzerland.
