PURPOSE:To obtain a sheet improved in vibration-damping performance with outstanding workability, etc., for use in vehicle floor surface, by forming with a material prepared by incorporating specific matrix with each specified amount of thermosetting resin, tackifier, and inorganic filler. CONSTITUTION:The objective sheet can be obtained by incorporating (A) 100pts. wt. of a matrix comprising A1: 20-80pts.wt. of a rubber component (e.g., NR, NBR) and A2: 80-20pts.wt. of bituminous component (e.g., straight asphalt) with (B) 10-100pts.wt. of a thermosetting resin co-crosslinkable with the component A1 (e.g., unsaturated polyester), (C) 10-150pts.wt. of a tackifier (e.g., petroleum-based hydrocarbon resin, cumarone-based resin), and (D) 50-500pts.wt. of at least one kind of inorganic filler (e.g., silicon compound consisting mainly of SiO2, calcium carbonate) followed by kneading and extruding into a sheet 2-6mm thick. |
