摘要

在飞机机翼尾节板、扰流板等部位深度修理过程中，实现发泡胶高效清除又不损伤铝合金基材，在航空修理领域一直备受关注。在红外光谱、热重等试验分析发泡胶固化后产物的基础上，采用溶胀理论，确定二氯甲烷作为除胶剂的主溶剂。引入TiO2改性SiO2纳米微胶囊作为二氯甲烷的吸附剂及缓释剂，通过物理吸附、物理隔离及缓慢释放等方式，来实现减少VOC 排放、延长除胶剂使用时间、提升脱胶性能。同时，采用石蜡和聚乙烯片进行表面阻隔，并在除胶剂的研制中加入Halox630 缓蚀剂，有效地减缓除胶剂的挥发和对基材的腐蚀。结果表明，研制的除胶剂对铝合金表面残留发泡胶表现出优异的脱胶效果，同时对热固性胶粘剂表现出优异的软化、溶胀效果。

Abstract

In the deep repair process of aircraft wing endplates， spoiler and other parts， the efficient removal of foam adhesive without damaging the aluminum alloy has been paid much attention in the field of aviation repair.In this study，the cured products of foam adhesive were analyzed using infrared spectroscopy and thermogravimetric analysis.Based on the swelling theory， dichloromethane was identified as the primary solvent for the adhesive remover.TiO2-modified SiO2 nanocapsules were introduced into dichloromethane as adsorbents and slow-release agents to reduce VOC emissions， extend the operating time of the adhesive remover， and improve its performance through mechanisms such as physical adsorption， physical isolation and slow release.Meanwhile， paraffin and polyethylene sheets were used as surface barriers， and Halox630 corrosion inhibitor was added to the formulation of the adhesive remover to effectively reduce the volatilization of the remover and the corrosion of the substrate.Results showed that the developed foam adhesive remover exhibited excellent degumming performance on residual foam adhesive on the surface of aluminum alloy， as well as outstanding softening and swelling effects on thermosetting adhesives.

Key words： foam adhesive; remover; swelling theory; slow-release; corrosion inhibitor
