水性密封胶的研究进展

Research Progress of Waterbornesealant

随着环保法规的日益严格和人们环保意识的不断提升,传统聚硅氧烷密封胶由于其高挥发性有机化合物(volatile organic compounds,VOC)排放,其使用范围受到较大限制。相比于聚硅氧烷密封胶,水性密封胶因其优异的环保特性,已成为当前密封胶领域的发展热门方向。综述了水性密封胶的聚合物种类、改性方式与应用方法。基于此,对水性密封胶的研究方向进行了展望。

With the increasingly stringent environmental regulations and the continuous improvement of people’s awareness of environmental protection,the traditional polysiloxane sealant is limited in its application due to its high volatile organic compounds(VOC)emission.Compared with polysiloxane sealant,waterborne sealant has become a hot development direction in the field of sealant due to its excellent environmental protection characteristics.In this paper,the polymer types,modification methods and application methods of waterborne sealants were reviewed.Based on this,the research direction of waterborne sealant was prospected.
