VIBRATION DAMPER COMPOSITION BASED ON EVA RESIN AND POLYISOPRENE RUBBER AND HAVING EXCELLENT WORKABILITY AND IMPACT RESISTANCE AND IMPROVED VIBRATION DAMPING EFFECT

摘要

PURPOSE: Provided is a vibration damper composition for damping vibrations in cars, which is adhered or fused by heating with ease, has excellent impact resistance, is used in a broad range of temperatures and controls vibrations in a car efficiently. CONSTITUTION: The vibration damper composition is obtained by heating a mixture comprising: 15-30 wt% of ethylene vinyl acetate resin; 5-15 wt% of polyisoprene rubber; 0.5-1.2 wt% of thiuram as a curing agent; 0.7-1.5 wt% of a quinoline based antioxidant; 3-9 wt% of aluminum trioxide as a flame retardant; 5-15 wt% of mica powder, 3-10 wt% of cellulose fiber, 20-40 wt% of barium sulfate and 5-13 wt% of heavy calcium carbonate as fillers; 2-6 wt% of a phthalate oil as a plasticizer; 3-5 wt% of carbon black as a reinforcing filler; and 3-10 wt% of micropearl as a light filler, so as to melt and blend the mixture completely, wherein the composition has no viscosity at room temperature.
