摘要
用甲基丙烯酸甲酯和丙烯酸正丁酯为核,丙烯酸异辛酯、丙烯酸和甲基丙烯酸正丁酯为壳,合成具有核壳结构的丙烯酸乳液;根据凝胶率、膜吸水率和乳液的黏度对乳液的影响确定功能单体的加入量为总单体的1.5%;讨论了核层玻璃化转变温度以及核层单体与壳层单体的质量比对乳液力学性能的影响;核层玻璃化转变温度为45℃,核层单体与壳层单体的比为40:60时所得的核壳乳液的力学性能最为理想。
With methyl methacrylate and n-butyl acrylate as core and iso-octyl acrylate, acrylic acid and n-butyl methacrylate as shell, the acrylic emulsion of core-shell structure is synthesized. According to the influence of gel rate, water absorption of film and the viscosity on emulsion, the amount of functional monomer is determined to be 1.5%. This paper discusses the influence of core layer glass transition temperature and the mass ratio of core layer monomer and shell layer monomer on mechanical property of the emulsion, concluding that the mechanical property of the emulsion is the most ideal when the glass transition temperature of core layer is 45℃ and the mass ratio of core layer monomer and shell layer monomer is 40：60.
