Title: Makoto Egashira: Innovator in Flame Retardants and Zirconia Hollow Particles

Introduction

Makoto Egashira is a notable inventor based in Nagasaki, Japan. He has made significant contributions to the field of materials science, particularly in the development of flame retardants and zirconia hollow particles. With a total of 3 patents to his name, Egashira's work has had a considerable impact on various industries.

Latest Patents

One of Egashira's latest patents is a flame retardant that boasts excellent dispersibility in resin ingredients. This innovative flame retardant enhances the flame-retardant properties and mechanical characteristics of resin moldings. The formulation includes magnesium hydroxide particles, which are bonded with a higher fatty acid, preferably stearic acid, on part of their surface. Additionally, a silicone oil with reactivity is bonded to the surface area of the magnesium hydroxide particles that does not have the higher fatty acid attached.

Another significant patent involves a producing method for zirconia hollow particles. This method allows zirconia powder to combine and form a porous shell layer, creating a hollow structure. The process is characterized by mixing a resin powder and a zirconia powder of a smaller grain size under pressurized contact. This results in a precursor where the zirconia powder partially embeds itself on the surface of the resin powder. The precursor is then calcined to expel the resin powder and sinter the zirconia powder together.
