热敏型压敏胶带的研制

Development of thermosensitive pressure sensitive adhesive tape

本热敏型压敏胶带的压敏胶以天然橡胶为主体 ,加入合成橡胶、增粘剂及其他助剂制成。胶带的基材是含有热敏剂的美纹纸。选用了一种比有机硅增粘剂交联温度低而且可以书写的高分子共聚物 (10 0℃以下交联 )作为防粘剂。确定了压敏胶的配方和胶带的生产工艺 ,并检测了各项性能。试验证明 ,该胶带在常温下无色 ,在高温时则会显示出标识、字迹或图案。在医学、科研等领域有广泛的用途。

Using nature rubber as the main material and adding synthetic rubber,tackifier and some other assistants the adhesive for thermosensitive pressure sensitive adhesive tape was prepared.The substrate of tape was the goffered paper containing the thermosensibilizer and the used releasing agent was a printable copolymer which was crosslinked at lower temperature(under 100 ℃)than that for polysiloxane tackifier.The adhesive formulation and the tape production process were determined and the product properties were detected.The tapes are colorless at ordinary temperature,but they will appear the marks,writtings or patterns at elevated temperature.The tapes have broad applications in dedicine,scientific research etc.
