Composition for Waterborne Polyurethane Elastomer Having High Anti-hydrolytic and Thermal Properties Based on Polyether Polyols of Low Monol Content and Manufacturing Method Thereof

摘要

The present invention relates to a method coating the ink binder fiber dispersion composition for a polyurethane elastomer and a production and relates to a polyurethane elastomer for making the prepolymer, the prepolymer composition of the present invention is an aromatic diisocyanate and an alicyclic diisocyanate is 1 on a weight basis: 1 to It is mixed in a ratio of 1, the de-1 in equivalent ratio so as to react with an isocyanate: 0.1 0.8 to 1: a polyol having a weight average molecular weight of 1000-5000 with a ratio of 1.2 are added, this polyol is polypropylene (propylene oxide oxide: PO) based polyether polyol is made to the default number is a short diol of 2 to 5% by weight was added to give a dispersion property. In order to neutralize the short diol is added characterized in that the neutralizing agent is fed to the equivalent ratio of the short diol.
