Water-based Polyurethane Leather Finishing and Synthesis of Mechanical Properties of Film
Technology)
Abstract: This article was synthesized with, 2.4-tolyldiisocyanate (TDI),polyether(E-210,HP-7010), dimethylol propionic acid(DMPA),the chain extendor,the crosslinking agent,and the deionized water according to the different formula.The performance of polyurethane emulsion and the film mechanics ,such as the film mechanics was analyzed.
Keywords: Aqueous polyurethane; crosslinking agent; The chain extendor; mechanics performance
