A heat-foaming rubber pad composition for automobile is provided to ensure physical properties(heat resistance, weather resistance and processability) and to reduce the noise by removing the noise acoustic resonance generated in automobiles. A heat-foaming rubber pad composition for automobile comprises (i) butadiene rubber, styrene thermoplastic resin, stearic acid, carbon black, calcium carbonate and process oil; and (ii) thiazole-based vulcanization accelerator, thiuram-based vulcanization accelerator, thiocarbamate-based promoter, urea-based promoter, metal oxides, azodicarbonamide-based foam, and oxybis-based foam.
