Corrosion inhibiting thermoplastic alloys

摘要

Corrosion inhibiting thermoplastic alloys and methods of preparing same for use in fabricating molded articles with long-term corrosion protection. Masterbatches of an ABS resin together with selected corrosion inhibitor formulations are extruded for use in molding operations particularly adapted for preparing protective enclosures for delicate metals, such as are present in electronic media devices and apparatus. Molded articles are prepared from acrylonitrile butadiene styrene resin and a solid phase corrosion inhibitor blended in situ, and wherein the resin consists essentially of acrylonitrile butadiene styrene, and wherein the corrosion inhibitor contains a blend of dicyclohexylammonium nitrite, sodium nitrite, benzotriazole, sodium molybdate and sodium sebacate.
