Abstract: A method for preparing a high-temperature self-crosslinking aqueous polyurethane dispersion. By using isocyanate (NCO) blocking agent to block part of the NCO, and using the hydroxyalkyl ethylenediamine chain extender in the post-chain extension stage to introduce hydroxyl groups, the polymer macromolecular structure containing both blocked NCO groups and hydroxyl groups can be prepared. The aqueous polyurethane dispersion does not need to mix with other waterborne resins and crosslinkers when applied. A sufficient cross-linking reaction is performed between the NCO released and hydroxyl groups on the polymer macromolecular chain to form a high-density cross-linked structure when curing at 100-150° C. for 20-30 min, thus obtaining a high-performance waterborne coating that can be used in the form of one-pack.

Abstract: Disclosed area coating-free metallic thermoplastic resin composition having improved metallic texture and gloss and a molded product having extrusion-molded the same.

The molded product may be manufactured by feeding the master batch in the side feeding method to improve various physical properties, increase the dispensability and compatibility between compositions, and improve black streaks and flow marks, thereby improving metallic texture and gloss as well as suppressing the occurrence of the appearance defects.
