GALVANIZED STEEL SHEET WITH A THERMAL DIFFUSION LAYER, OF WHICH THERMAL CONDUCTIVITY AND COATING PROPERTIES ARE EXCELLENT

摘要

PURPOSE: A galvanized steel sheet with a thermal diffusion layer has excellent thermal conductivity and durability in respect to thermal shock and provides excellent mechanical properties capable of being applied to a flexible portion.;CONSTITUTION: A galvanized steel sheet with a thermal diffusion layer includes a galvanized steel sheet (10) and a thermal diffusion layer (20). The thermal diffusion layer is formed on one surface or both surfaces of the steel sheet and includes 1-60 wt% of graphene, 10-70 wt% of an organic binder, 0.1-8 wt% of a dispersing agent, and a solvent. A chromate or chrome-free preprocess layer is additionally formed on one surface or both surfaces of the galvanized steel sheet.;COPYRIGHT KIPO 2013
