Abstract

In the presented work, organophilized montmorillonites (OMMT) with selected quaternary ammonium compounds (QAC) with different chemical structure ((trioctylmethylammonium chloride-A336, dimethyloctadecyl[3-trimethoxysilyl)propyl]ammonium chloride-D, cetyltrimethylammonium bromide-CTAB, 2-methacryloxyethyltrimethylammonium chloride-MOA) were obtained and used as fillers for physically modified silicone pressure-sensitive adhesives (Si-PSA). Before OMMT addition into Si-PSA matrix, they were analyzed via TGA and XRD techniques. Type of chemical structure of QAC affected d-spacing of OMMT. New self-adhesive materials were obtained based on prepared Si-PSA compositions by adding the obtained fillers to the polymer matrix. New tapes exhibit a good level of useful properties as adhesion, cohesion, and tack-the values did not change or slightly decreased; in addition, the tapes with addition of OMMT showed high thermal resistance reaching the measuring limit of the test equipment-to 225 °C.

摘要

在本研究中，制备了含有不同化学结构的季铵化合物（QAC）（三辛基甲基氯化铵 - A336、二甲基十八烷基[3 - 三甲氧基硅基）丙基]氯化铵 - D、十六烷基三甲基溴化铵 - CTAB、2 - 甲基丙烯酰氧基乙基三甲基氯化铵 - MOA）的有机化蒙脱土（OMMT），并将其用作物理改性有机硅压敏胶粘剂（Si - PSA）的填料。在将OMMT添加到Si - PSA基体之前，通过热重分析（TGA）和X射线衍射（XRD）技术对其进行了分析。QAC的化学结构类型影响了OMMT的d间距。通过将所得填料添加到聚合物基体中，基于制备的Si - PSA组合物获得了新型自粘材料。新型胶带在粘附性、内聚性和粘性等有用性能方面表现出良好水平，这些值没有变化或略有下降；此外，添加了OMMT的胶带显示出高耐热性，达到测试设备的测量极限——高达225℃。
