摘要: 探究了国外某产品与军用防腐膜HP8714在关键技术指标水蒸气透过量及12 s垂直燃烧的性能,并以乙酸乙酯EAC为胶黏剂溶剂研究了胶黏剂种类及含量对防潮胶带性能的影响。结果表明,HP8714的热塑性聚氨酯原料A198FR可作为高性能阻燃热塑性聚氨酯防潮胶带的树脂原料,并以A198FR为树脂原料,确定压敏胶YY16为最适宜胶黏剂,优选YY16/EAC配比为75/25,并通过第三方测试验证所有指标。

Abstract: The performance of a foreign product and military anti?corrosion film (HP8714) was evaluated in terms of several key technical indicators, including water vapor transmission and vertical burning for 12 s, and the effects of adhesive type and content on the performance of the moisture barrier tapes were investigated by using ethyl acetate (EAC) as an adhesive solvent. The results indicated that the HP8714 TPU raw material (A198FR) could be used as a raw resin for the high?performance flame?retardant TPU moisture barrier tapes. With A198FR as the base material for barrier tapes, the pressure?sensitive adhesive, YY16, was determined as the most suitable adhesive at a preferred YY16/EAC mass ratio of 75/25. All of the property indexes were verified by third?party testing.
