NANOCOMPOSITE FOAM COMPOSITION FOR INSOLE COMPRISING GLASS BEADS WITH EXCELLENT FORM RESTORATION AND MECHANICAL PROPERTIES, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A nanocomposite foam composition for insole is provided to improve form restoration and mechanical properties without accepting additional apparatus or device, and to improve distribution of additives for foam and a layered silicate by a ball-bearing effect.;CONSTITUTION: A nanocomposite foam composition comprises 0.5-10 parts by weight of anionic surfactant, 2-10 parts by weight of organically layered silicate, 2-10 parts by weight of glass beads, 0.5-1.5 parts by weight of an organic peroxide crosslinking agent, 3-10 parts by weight organic foam, and 3-30 parts by weight of additives for foam. The polymer substrate consists of 50-80 weight% of a hydrogenated styrene/butadiene block copolymer, and 20-50 weight% of an ethylene vinyl acetate copolymer.;COPYRIGHT KIPO 2013;[Reference numerals] (S1) First mixing step for mixing anionic surfactant into a polymer substrate; (S2) Second mixing step for mixing organized lamellar silicate and glass beads into a mixture mixed through the first mixing step; (S3) Sheet-manufacturing step for mixing a crosslinking agent, a foaming agent, and additives for a foam into a mixture mixed through the second mixing step and molding into a sheet; (S4) Foam-manufacturing step for molding a milled sheet manufactured through the sheet-manufacturing step to obtain a foam
