DOUBLE-SIDED ADHESIVE TAPE
To provide a double-sided adhesive tape capable of fixing to an adherend without generating floating at an edge portion, even in a structural surface material that generates a warp due to a temperature change.SOLUTION: A double-sided adhesive tape for fixing a structural surface material to an adherend, has performances of: a moving distance of a steel ball of 40 mm or less in a rolling ball tack test method that evaluates adhesiveness based on the moving distance on a double-sided adhesive tape of a steel ball of a diameter of 21.4 mm and a weight of 40 g rolled from a slope with an inclination angle of 21.5° and a height of 65.1 mm under a temperature environment of 5°C; and stainless steel sheets of a test piece remaining without falling in a holding power test in which the test piece is prepared of 25 mm square double-sided adhesive tape sandwiched between the two stainless steel sheets made to adhere to each other and cured for 18 hours at 40°C, and the test piece is maintained for one hour in s state that a weight of 1.5 kg is suspended at an edge portion of one of the stainless steel sheets of the test piece.SELECTED DRAWING: None
【課題】気温変化により反りが発生する構造用面材であっても、端部の浮きを発生させずに被着体に固定させる両面粘着テープを提供することを課題とする。【解決手段】構造用面材を被着体に固定させるための両面粘着テープであって、５℃の温度環境下で、傾斜角度２１．５°、高さ６５．１ｍｍの斜面から転がした直径２１．４ｍｍ、重さ４０ｇの鋼球の両面粘着テープ上の移動距離に基づいて粘着性を評価するローリングボールタック試験法における鋼球の移動距離が４０ｍｍ以下であり、２５ｍｍ角の両面粘着テープを２枚のＳＵＳ板で挟み圧着させて、４０℃で１８時間養生させた試料を準備し、該試料の一方のＳＵＳ板の端部に１．５ｋｇのおもりを吊るした状態で１時間経過させる保持力試験においてＳＵＳ板が落下しない、両面粘着テープ。【選択図】なし
