| 摘 要： | 以AA-PVA(乙酰乙酰化聚乙烯醇)为保护胶体、丙烯酸丁酯(BA)和叔碳酸乙烯酯(VeoVa10)为聚醋酸乙烯酯(PVAc)乳液的共聚改性单体,制得改性PVAc乳液胶粘剂。研究结果表明:当聚合温度为75℃、AA-PVA浓度为5%、w(BA)=7%和w(VeoVa10)=16%(均相对于PVAc乳液质量而言)时,相应改性PVAc乳液的剪切强度和耐水性俱佳。

| Abstract: | With AA-PVA(acetoacetyl polyvinyl alcohol) as protective colloid,butyl acrylate(BA) and vinyl versatate(VeoVa10) as modified comonomers of polyvinyl acetate(PVAc) emulsion,a modified PVAc emulsion adhesive was prepared.The research results showed that the corresponding modified PVAc emulsion had both good shear strength and good water resistance when the polymerization temperature was 75 ℃,concentration of AA-PVA was 5%,mass fractions of BA and VeoVa10 were 7% and 16% in PVAc emulsion respectively. |
