Title: Kaichiro Nakao: Innovator in Polyamide Resin Technology

Introduction

Kaichiro Nakao is a prominent inventor based in Hyogo, Japan. He has made significant contributions to the field of polyamide resin technology, holding a total of 2 patents. His work focuses on the development of innovative materials that have practical applications in various industries.

Latest Patents

Nakao's latest patents include an aqueous polyamide resin dispersion and a process for producing adhesive for fusion bonding. The aqueous dispersion of polyamide resin comprises dispersed polyamide resin particles, a basic material, and water. The dispersed polyamide resin particles have a weight-average diameter ranging from 0.1 to 10 micrometers. The ratio of end carboxyl groups to end amino groups in the polyamide resin is maintained between 60/40 and 100/0. The amount of basic material added is between 0.2 and 3.0 moles per mole of end carboxyl groups. This innovative aqueous dispersion can be manufactured by adding the polyamide resin to an aqueous dispersion medium containing the specified amount of basic material.

Additionally, Nakao has developed a process for producing a heat-fusion bonding adhesive. This adhesive is prepared by heating a thermoplastic resin to a temperature above its softening point and then dispersing the resin in an aqueous medium. The dispersion process involves applying shear force to the aqueous medium through stirring until the thermoplastic resin is divided into particles with a weight-average particle size of 0.1 to 20 micrometers.
