环保型水性上光油的制备及性能

采用半连续种子乳液聚合的方法，选择合适的单体进行乳液聚合，合成了印刷用环保型上光油，探讨了丙烯酸丁酯和甲基丙烯酸甲酯的比例、乳化剂的种类和用量、引发剂用量及pH值对乳液性能的影响，结果表明：丙烯酸丁酯和甲基丙烯酸甲酯比例为0．85，OP-10与SDS组成的复合乳化剂用量为2．5％，引发荆为0．25％时最佳，该上光油具有光泽好，耐化学品性能强，稳定性良好等特点。

The Preparation and Performance Testing Of An Environment Friendly Water-soluble Varnish

An environment friendly varnish used for printing papers was synthesized by semt-conunuous adding monomers and seed emulsion polymerization technology with suitable monomers. The factors that influenced the emulsion properties were discussed, including the ratio of BA-MMA monomers,the kind and amount of emulsifying agent, the amount of the initiator and so on. The results showed that the ratio of the BA-MMA was 0.85, the best dosage of the composite emulsifier of OP-10 and SDS was 2.5% ,and the initiator was 0.25%. The varnish had high gloss, excellent chemical resistance and stability.
