近代以来使用厌氧胶等化学粘合剂来实现紧固件的防松效果是普遍的工艺。但随着现代科技的发展以及生产需求的扩大,厌氧胶必需的复杂涂胶工序限制了其在生产装配线的效率,工业上对厌氧胶的使用提出了简单化的要求,而通过微胶囊技术制得的微胶囊化厌氧胶能很好地满足这一要求。综述了厌氧胶和微胶囊化厌氧胶的化学组成,着重介绍了微胶囊化厌氧胶,包括微胶囊的制备方法以及单胶囊厌氧胶与双胶囊厌氧胶的研究进展。旨在通过梳理材料设计和微胶囊化技术等核心领域的分散研究成果,构建完整的理论框架,为可预涂微胶囊型厌氧胶的开发和应用提供参考。
In recent times,the use of chemical adhesives such as anaerobic adhesives to realize the anti-loosening effect of fasteners has been a common process.However,with the development of modern science and technology as well as the expansion of production needs,anaerobic adhesives necessary complex gluing process limits its efficiency in the production assembly line,the industry has put forward the simplification of the use of anaerobic adhesives,and microencapsulated anaerobic adhesives produced by microencapsulation technology can well meet this requirement.This article reviewed the chemical compositions of anaerobic adhesives and microencapsulated anaerobic adhesives,with an emphasis on microencapsulated anaerobic adhesives,including the preparation methods of microcapsules and advances in the study of single-capsule and dual-capsule anaerobic adhesives.The review aims to construct a complete theoretical framework for the development and application of pre-coatable microencapsulated anaerobic adhesives by combing the dispersed research results in the core areas of material design and microencapsulation technology.
