    • PROBLEM TO BE SOLVED: To provide an edge sealing tape which is used for preventing exfoliation of a coating film protective sheet and has both of reworkability and resistance to exfoliation at high levels when the work of sticking the edge sealing tape is performed. SOLUTION: The edge sealing tape 10 is used for fixing the edge 20A of the coating film protective sheet 20 to an adherend 30 having a coating film 32. The edge sealing tape 10 is provided with: a rubber-based adhesive layer 16 arranged on one side of a sheet-shaped support 12; and an adhesive strength increasing agent 14 which is arranged between the rubber-based adhesive layer 16 and the sheet-shaped support 12 and is used for increasing the adhesive strength of the rubber-based adhesive layer 16 with time. The adhesive strength increasing agent 14 is an acid-modified polyolefin resin, which has not a dominant endothermic peak corresponding to the softening temperature when measured by a DSC (differential scanning calorimeter) by raising the temperature from -10°C to 200°C at 10°C/minute temperature rise rate, and/or a chlorinated polyolefin resin having COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种边缘密封带,其用于防止涂膜保护片的剥离,并且当执行粘合边缘密封带的工作时,具有高的水平的再加工性和耐剥落性。 解决方案:边缘密封带10用于将涂膜保护片20的边缘20A固定到具有涂膜32的被粘物30.边缘密封带10设置有橡胶基粘合剂层16 布置在片状支撑体12的一侧; 以及布置在橡胶基粘合剂层16和片状载体12之间的粘合强度增加剂14,并且用于随时间增加橡胶基粘合剂层16的粘合强度。 粘合强度增加剂14是酸改性聚烯烃树脂,其通过DSC(差示扫描量热计)通过将温度从-10℃升温至200℃而不具有与软化温度相对应的主要吸热峰, 10℃/分钟升温速率,和/或通过DSC测量时具有<10℃玻璃化转变温度的氯化聚烯烃树脂。 版权所有(C)2009,JPO&INPIT
