核壳型调金油乳液的制备及应用研究

采用单体预乳化结合种子聚合法合成具有核壳结构的调金油乳液。对乳胶粒核壳结构、功能单体甲基丙烯酸（MAA）的用量、交联单体N-羟甲基丙烯酰胺（N—MA）的用量及配墨乳液用量对银墨性能的影响进行了讨论。结果表明：MAA所占单体总量质量比为3％、N—MA为3％时所制备的核壳结构的调金油乳液配墨性能最佳，银墨的最佳物料质量配比为异丙醇15％、铝银浆15％、调金油乳液70％。

Research on Preparation and Application of Core-shell Emulsion for Metallic Inks

A core-shell emulsion for metallic inks was synthesized by methods of monomer pre-emulsifieation combined with seed polymerization. The effects of core-shell structure of latex particle, amount of functional monomer methacrylic acid （MAA）, amount of crosslinking monomer N- methylol aerylamide （N-MA） and amount of emulsion on the performance of the silver ink were discussed. The results showed that when the mass ratio of MAA and N-MA were both 3% of the total monomer, the core-shell emulsion with best performance could be prepared. The optimal proportion of materials for silver ink was showed as follows： the mass ratio of isopropanol, aluminum paste and the prepared emulsion was 15%, 15% and 70% respectively.
