MANUFACTURING METHOD OF A PINE BOARD FOR BREAKING, CONSISTING OF RECYCLED EPS AND WOOD COMPONENTS AND A PINE BOARD MANUFACTURED BY THE SAME

摘要

PURPOSE: A manufacturing method of a pine board for breaking is provided to consist of recycled EPS(expandable polystyrene) and wood components as main ingredients, thereby not forming sharp part after breaking, and preventing safety accident.;CONSTITUTION: A manufacturing method of a pine board for breaking comprises: a step of manufacturing recycled EPS(Expandable polystyrene) to a chip shape of 3-5 cm by heating synthetic resin waste to 120-140 °C, cooling the same, and pulverizing the same; a step of manufacturing wood powder by pulverizing one wood component selected from hardwood, wood pillar, log, waste wood and waste furniture; a step of mixing 75 parts by weight of the recycled EPS, 3-50 parts by weight of the wood powder, 2 parts by weight of wonder, 1 parts by weight of a foaming agent, 0.07 parts by weight of DOP(dioctyl phthalate); and a step of manufacturing a pine board for breaking by extruding the mixture in an extruder of 160-200 °C, cooling and cutting the same. The synthetic resin waste consists of panel, packing styrofoam, an icebox, and a marine float.;COPYRIGHT KIPO 2012
