利用顺丁烯二酸酐(MA)、苯酐(PA)、均苯四酸二酐(PMDA)、二苯酮四酸二酐(BTDA)分别与γ-氨丙基三乙氧基硅烷(γ-APS),通过化学亚胺化制备了一系列新型高耐热酰亚胺芳杂环改性硅烷偶联剂,并讨论了溶剂体系、亚胺化试剂对合成的影响。还通过表面硅烷化技术,将基于新型高耐热改性硅烷偶联剂的处理液对金属进行防腐处理,考察了处理液的配置及储存稳定性,阐述了将其用于Al、Fe、Cu金属表面处理的原理和处理工艺,分析讨论了不同改性硅烷偶联剂与保护膜之间结构性能的关系。
(MA), phthalic anhydride (PA), pyromellitic dianhydride (PMDA), benzophenonetetracarboxylic dianhydride (BTDA) and γ- aminopropyltriethoxysilane (γ- APS), a series of novel highly heat-resistant imide aromatic heterocyclic modified silane coupling agents were prepared by chemical imidization. The effects of solvent system and imidization agent on the synthesis were also discussed. The surface silanization technology was also adopted to treat the metal based on the new heat-resistant silane coupling agent-treated liquid. The disposition and storage stability of the liquid were also investigated. It was also described that Al, Fe, Cu Metal surface treatment principle and processing technology, analysis and discussion of different modified silane coupling agent and protective film between the structural properties of the relationship.
