EXPANDABLE STARCH BEAD CAPABLE OF MANUFACTURING FOAM WITH SPECIFIC SHAPE IN A MOLD OF VARIOUS SHAPES LIKE EXPANDABLE STARCH BEADS, USING ENVIRONMENT-FRIENDLY STARCH AS MAIN MATERIAL

摘要

PURPOSE: An expandable starch bead is provided to manufacture foam with specific shape in a mold of various shapes like expandable starch beads, and to have environment-friendly performance disassembled by microorganisms in soil.;CONSTITUTION: An expandable starch bead is comprises 90-99 parts by weight starch-monomer copolymer and 1-10 parts by weight blowing agent. A manufacturing method of the expandable starch bead comprises: a step of manufacturing a starch-monomer copolymer and a step of manufacturing a micropellet by mixing the starch-monomer copolymer and a resin; and a step of containing foam into the micropellet. The starch-monomer copolymer comprises 10-90 parts by weight starch and 10-90 parts by weight monomer. The diameter of the micropellet is 0.5-5.0mm.;COPYRIGHT KIPO 2012
