摘要：<p>PROBLEM TO BE SOLVED: To easily unroll by improving vibration-damping properties by winding a mold releasing film or sheet as a rolled unit between damping sheets for folded plate roof and preventing adherence of the film or sheet even in the case of winding it as the rolled unit in a manufacturing step. SOLUTION: Styrene-isoprene block copolymer C9 resin and resin composition containing calcium carbonate and mica as inorganic powder are supplied to an extruder, heated, and kneaded. And, a damping sheet for a roof is extrusion molded by the extruder. In the case of winding the damping sheet, mold releasing film is interposed between the damping sheets to obtain a rolled unit. Thus, in the case of winding it as the unit in the step of manufacturing the damping sheet for folded plate roof, the releasing film or sheet is interposed between the damping sheets to obtain the unit. Since the releasing film or sheet is interposed in the case of winding the damping sheet for the folded plate roof as the unit, adhesion of the damping sheets to one another can be prevented.</p>
