研制了一种改性的聚乙酸乙烯酯(PVAc)乳液,通过添加适量的BA、MMA和AA单体进行核壳共聚,用保护胶体聚乙烯醇后缩醛化和乳化剂改性相结合的方法,成功地解决了通用聚乙酸乙烯酯乳液的防水性、防冻性及贮存稳定性较差的问题。
A modified polyvinyl acetate (PVAc) emulsion was prepared by adding appropriate amount of BA, MMA and AA monomers for core-shell copolymerization, and after the protective colloid PVA was acetalized and emulsifier modified Method, successfully solved the common polyvinyl acetate emulsion waterproofing, antifreeze and storage stability problems.
