POLYURETHANE POROUS STRUCTURE OF NON-SOLVENT TYPE AND METHOD THEREOF USING FOR ARTIFICIAL SYNTHETIC LEATHER

摘要

The present invention relates to a non-solvent-type polyurethane porous body containing micropores without using an organic solvent and a method for manufacturing artificial leather using the polyurethane porous body using the same.;The present invention utilizes a urethane prepolymer A component containing a hydroxyl group (Hydroxy, -OH) group in a liquid or semi-solid state at room temperature (12 to 18 ° C) at room temperature (12 to 18 ° C), or 30 to 80 B component, an isocyanate compound capable of reacting with the hydroxyl group of the urethane prepolymer, and C component, which is a mixture of a crosslinking curing catalyst, a pore-forming co-catalyst, and a foaming agent, are introduced in a fixed amount. A high-strength solvent-free urethane porous body and artificial leather using the same can be produced by heating and curing the cream-like porous body formed by high speed and mixing at a temperature of 60 to 130 ° C.;In addition, the polyurethane porous body and the artificial leather produced by the above method exhibits high productivity with high productivity and excellent chemical and physical properties.;Microporous, Solvent-free Urethane, Porous Body, Artificial Leather
