METHOD FOR MANUFACTURING HIGHLY FLAME RESISTANT AND ECO-FRIENDLY RUBBER-BASED NANOCOMPOSITE FOAM USING WASTE RUBBER FOAM POWDER

摘要

The present invention relates to a method for manufacturing a high-flammability and eco-friendly rubber-based nanocomposite foam using waste rubber foam powder, and more particularly, to a waste rubber powder comprising rubber, a flame retardant mixture including waste rubber foam powder, and a processing aid. Flame-retardant masterbatch manufacturing step of manufacturing high-flammability eco-friendly rubber-based nanocomposite masterbatch, rubber resin, high-flammability eco-friendly rubber-based nanocomposite masterbatch using waste rubber powder manufactured through the flame-retardant masterbatch manufacturing step, masterbatch for foaming and crosslinking A raw material mixing step of mixing the master batch, an extrusion step of extruding the mixture prepared through the raw material mixing step, a foaming step of foaming the extruded product manufactured through the extrusion step. and a cutting step of cutting the foamed product through the foaming step. The foam produced through the above process does not contain a halogen-based flame retardant component, is eco-friendly by recycling waste rubber foam powder, is light in weight and exhibits excellent sound absorption performance, and has excellent flame retardancy, heat insulation, heat resistance and mechanical properties.
