METHOD FOR MANUFACTURING ENVIRONMENTALLY FRIENDLY SYNTHETIC LEATHER USING AQUEOUS DISPERSION TYPE POLYURETHANE RESIN COATING SOLUTION APPLIED TO VARIOUS FURNITURE AND HOUSEHOLD ITEMS

摘要

The present invention relates to a method for manufacturing synthetic leather using an aqueous dispersion type polyurethane resin (PUD) coating solution applied to various furniture and household items such as bags, interior wallpaper, etc, and more specifically, to a method for manufacturing environmentally friendly synthetic leather free from volatile organic compounds (VOC) without harmfulness caused by residual volatile organic solvents applied to various furniture and household items such as bags, interior wallpaper, etc requiring a texture of natural leather by using an aqueous dispersion type polyurethane resin prepared by not using organic solvents such as di-methylformamide (DMF), toluene and methyl ethyl ketone (MEK) which are used in polymerization of conventional polyurethane, and providing a cushion layer by proceeding foaming and expansion with microsphere on a coating layer.;COPYRIGHT KIPO 2016
