HDPE/ nano-magnesium hydroxide ( MH ) surface modified in solvent / microencapsulized red phosphorus ( MRP ) non-halogen flame-retarded composites was prepared by meltblending.The influence of the ratio of material
surface modification on properties of composites was studied.The results showed: the surface modification for MH in solvent makes the modifiers adhere to the surface of MH
the particles size increase slightly.The pictures taken by SEM shows that the surface modification is propitious to the dispersing of flame retardant in resin.Adding MRP to MH bring synergistic effect in improving the flame retardancy
the influence on mechanical properties is unconspicuous.When the ratio of HDPE/MH/MRP is 100/50/7.5
the composites own good flameretardant and mechanical properties.
