ELECTRO-DEPOSITION FOAM-TYPE SPOT SEALER COMPOSITION CAPABLE OF IMPROVING WORK STABILITY AND CHARGING ABILITY OF ASPOT WELDING SITE

摘要

PURPOSE: An electro-deposition foam-type spot sealer composition is provided to lower electric resistance value and enhance heat tolerance.;CONSTITUTION: An electro-deposition foam-type spot sealer composition comprises 5-10 weight% of styrene butadiene rubber, 5-10 weight% of isoprene rubber, 5-10 weight% of polybutene, 3-5 weight% of thermosetting resin, 3-5 weight% of thermoplastic resin, 25-40 weight% of calcium carbonate, 25-35 weight% of plasticizer, 1-3 weight% of sulfur, 0.3-1 weight% of rubber accelerator, 3-5 weight% of electro-deposition carbon black, 5-10 weight% of a foaming agent and 3-7 weight% fire retardant filler. The thermosetting resin is one or more kind selected from bisphenol epoxy resin, dimer-modified epoxy resin, novolak modified epoxy resin, fatty acid modified epoxy resin and phenol modified epoxy resin.;COPYRIGHT KIPO 2012
