国外从20世纪70年代就开展预涂型锁固密封胶的研究及应用工作,因其可部分代替液态型厌氧胶,提高汽车等机械行业生产自动化水平,国内也从上世纪80年代开展预涂型锁固密封胶的研究,并在东风汽车公司成功应用;预涂型锁固密封胶分溶剂型及水基型两大类,水基型具有安全环保等优势,本文概述了水基预涂型密封胶的国内外技术发展概况,主要对水基型预涂微胶囊厌氧锁固密封胶和单组分水基型预涂密封胶的研究、性能及应用情况作了简要的介绍和展望。
Foreign 70s from the 20th century to carry out pre-coated locking sealant research and application work, because it can partially replace the liquid anaerobic adhesive to improve the automotive and other machinery industry production automation level, the domestic from the 80s of last century to carry out pre- Coated locking sealant and successfully applied in Dongfeng Motor Company. The pre-coated locking sealant is divided into two major categories: solvent-based and water-based, water-based with safety and environmental protection advantages. At home and abroad technical overview of coated sealant, the research, performance and application of water-based pre-coated microcapsule anaerobic locking sealant and one-component water-based pre-sealant are briefly introduced. Outlook.
