水性ポリウレタン分散物の連続製造方法

Title:

水性ポリウレタン分散物の連続製造方法

Document Type and Number:

Japanese Patent JP5000854

Kind Code:

B2

Abstract:

Continuous preparation of aqueous polyurethane dispersion (I) (based on at least aliphatic and/or aromatic polyisocyanate) comprises: (a) preparing an aqueous preemulsion by mixing a hydrophilic and/or potential hydrophilic group containing polyurethane pre polymers (II) with water in a mixing nozzle, where (II) is soluble in water; and (b) forming an emulsion by homogenizing the preemulsion in a multi-level homogenizing nozzle. An independent claim is also included for a substrate coated with a lacquer layer using (I) prepared by the method.
