摘要
研制了一种改性聚醋酸乙烯乳液 ,通过添加丙烯酸丁酯 (BA) ,甲基丙烯酸甲酯(MMA)和丙烯酸 (AA)核壳共聚 ,用保护胶体聚乙烯醇 (PVA)缩醛化和乳化剂改性相结合的方法 ,成功地解决了通用聚醋酸乙烯 (PVAc)乳液的稳定性、抗冻性和抗水性差的问题。
This article introduces a new kind of modified polyvinyl acetate(PVAc) emulsion.The problem of common PVAc emulsion's stability and freezing resistance and water resistance properties were successfully solved by adding butyl acrylate (BA),methyl methacrylate (MMA) and acrylic acid (AA) comonomer with means of core shell emulsion copolymerization.In the system,the use of polyvinylalcohol(PVA) for dispersing and emulsifying agent for modifing.
