Title: Kaoru Inoue: Innovator in Automotive Resin Technology
Introduction
Kaoru Inoue is a prominent inventor based in Toyota, Japan. He has made significant contributions to the field of automotive materials, particularly in resin compositions used for exterior parts. With a total of 4 patents to his name, Inoue's work has had a substantial impact on the automotive industry.
Latest Patents
Inoue's latest patents include a resin composition specifically designed for automotive exterior applications. This innovative resin composition comprises 50 to 70% by weight of crystalline propylene-ethylene block copolymer, 18 to 25% by weight of elastomeric polymer, and 15 to 25% by weight of inorganic filler. The elastomeric polymer is a mixture of a copolymer rubber produced from ethylene and an α-olefin having six or more carbon atoms, an ethylene-α-olefin-nonconjugated polyene random copolymer, and a hydrogenated styrene-conjugated diene block copolymer. This composition exhibits excellent processability and possesses a good balance of physical properties, including flexural modulus, impact resistance, hardness, and brittleness temperature. Moldings fabricated from this resin show a good appearance, free of any remarkable flow marks or weld marks on the surface.
Another notable patent by Inoue is a resin-molded product that includes a phenol-based oxidation inhibitor and a thiol-based compound. The thiol-based compound reacts chemically with a coloring substance resulting from the phenol-based oxidation inhibitor, interrupting a long conjugated system that arises in the coloring substance. This innovative approach effectively cancels the absorption due to the coloring substance in the visible light region, thereby inhibiting yellowing in the resin-molded product.
