Abstract
A nanometer structured synthetic leather fabrication method using the feature of hard segment of PU to be a nanometer structured material or the tie down point of other nanostructured materials to bond nanometer particles to PU molecular chains or to directly add nanometer structured particles to PU resins, forming a nanometer structured PU of modulus 100% within 60˜150 kg/cm2.
Claims18
A nanometer structured synthetic leather made from polyurethane of segmented copolymer having soft segment and hard segment and chain extender, said soft segment being formed of high molecular weight polyol, said hard segment being formed of diisocyanate, said polyurethane comprising 3˜6 moles hard segment including chain extender and 1 mole soft segment, having modulus 100% within 50˜150 kg/cm3.
