Abstract

The study examined how diatomite and its modifications affected the self-adhesive ability of silicone pressure-sensitive adhesives. To create adhesive composition for testing, fillers were added to a commercial silicone resin, which were then used to create new modified pressure-sensitive tapes. The resulting tapes were tested to determine their adhesion, tack, cohesion at room and elevated temperature, SAFT test (Shear Adhesive Failure Temperature), pot-life (viscosity) and shrinkage. The results obtained were compared with those of the unmodified tapes. The tests resulted in higher thermal resistance (225 °C) and lower shrinkage (0.1%). As a result, we can conclude that materials with thermal resistance with a slight decrease in other parameters were obtained.

摘要

该研究考察了硅藻土及其改性对有机硅压敏胶粘剂自粘能力的影响。为制备用于测试的胶粘剂组合物，将填料添加到一种市售有机硅树脂中，然后用其制备新型改性压敏胶带。对所得胶带进行测试，以确定其在室温和高温下的粘附力、粘性、内聚力、SAFT测试（剪切胶粘剂失效温度）、适用期（粘度）和收缩率。将所得结果与未改性胶带的结果进行比较。测试结果显示出更高的耐热性（225℃）和更低的收缩率（0.1%）。因此，我们可以得出结论，获得了耐热性良好但其他参数略有下降的材料。
