Pressure-sensitive adhesive tapes are used in several industrial applications such as construction, railway vehicles and the automotive sector, where the burning behavior is of crucial importance. Flame retarded adhesive tapes are developed and provided, however, often without considering the interaction of adhesive tapes and the bonded materials during burning nor the contribution of the tapes to fire protection goal of the bonded components in distinct fire tests. This publication delivers an empirical comprehensive knowledge how adhesive tapes and their flame retardancy effect the burning behavior of bonded materials. With a special focus on the interaction between the single components, one flame retarded tape and one tape without flame retardant are examined in scenarios of emerging and developing fires, along with their bonds with the common materials wood, zinc-plated steel, mineral wool, polycarbonate, and polymethylmethacrylate. The flame retardant significantly improved the flame retardancy of the tape as a free-standing object and yielded a V-2 rating in UL 94 vertical test and raised the Oxygen Index by 5 vol.%. In bonds, or rather laminates, the investigations prove that the choice of carrier and substrates are the factors with the greatest impact on the fire properties and can change the peak of heat release rate and the maximum average rate of heat emission up to 25%. This research yielded a good empirical overall understanding of the fire behavior of adhesive tapes and bonded materials. Thus, it serves as a guide for tape manufacturers and applicants to develop tapes and bonds more substrate specific.

压敏胶带和粘合材料的燃烧性能

压敏胶带用于多种工业应用，例如建筑、铁路车辆和汽车行业，其中燃烧性能至关重要。然而，阻燃胶带的开发和提供通常没有考虑胶带与粘合材料在燃烧过程中的相互作用，也没有考虑胶带在不同的火灾测试中对粘合部件的防火目标的贡献。本出版物提供了胶带及其阻燃性如何影响粘合材料的燃烧行为的经验性综合知识。特别关注单个组件之间的相互作用，在火灾出现和发展的情况下检查一种阻燃胶带和一种不含阻燃剂的胶带，以及它们与常见材料木材、镀锌钢、矿棉、聚碳酸酯和聚甲基丙烯酸甲酯。该阻燃剂显着提高了胶带作为独立物体的阻燃性，并在 UL 94 垂直测试中获得了 V-2 等级，并将氧指数提高了 5 vol.%。在粘合或层压板中，研究证明载体和基材的选择是对防火性能影响最大的因素，可以将热释放速率峰值和最大平均热发射速率改变高达 25%。这项研究对胶带和粘合材料的防火行为产生了良好的实证整体理解。因此，它可以作为胶带制造商和申请人开发更针对基材的胶带和粘合剂的指南。
