RESIN COMPOSITION FOR PREPARING FLAME RETARDANT POLYOLEFIN FOAMED PARTICLES HAVING IMPROVED MELT ADHESION AND FOAMABILITY

摘要

A flame retardant polyolefin resin composition, and a method for preparing a polyolefin foamed particle by using the composition are provided to inhibit bleeding out and blooming, thereby improving melt welding and secondary foaming property. A flame retardant polyolefin resin composition comprises 100 parts by weight of a polyolefin resin; 1-30 parts by weight of a halogen-based flame retardant; 1-30 parts by weight of an ethylene-vinyl acetate resin; 1-50 parts by weight of nanoclay; 2-50 parts by weight of a foaming agent; and 150-500 a dispersion medium. Preferably the ethylene-vinyl acetate resin contains 1-35 wt% of a vinyl acetate group; and the nanoclay is an organic onium ion-intercalated nanoclay.
