| 目的 探究聚合软硬单体比例对水性上光油性能的影响。方法 以丙烯酸丁酯（BA）、 甲基丙烯酸甲酯（MMA）为软硬单体， 过硫酸铵为引发剂， 采用半连续自由基乳液聚合方式合成目标上光油，通过改变配方中软硬单体的质量比， 分析单体比例对水性上光油的成膜性、 吸水率、 玻璃化转变温度， 以及涂覆后的明度、 光滑度、 耐磨性和耐水性等性能的影响。结果 软硬单体质量比在17∶13到2∶3（接近1∶1）时， 由于亲水与疏水基团的共同作用， 水性上光油成膜性、 明度、 光滑度和耐磨性达到最佳。结论 实验合成的环保水性上光油具有优良的成膜性和透明度， 可以满足印刷品和纸包装材料涂覆时的综合性能要求。 |

| To discuss the effects of the polymerizing soft and hard monomer ratio on the waterborne varnish properties of acrylate. Waterborne acrylate varnish was prepared by semi-continuous radical emulsion polymerization using butyl acrylate (BA) and methyl methacrylate (MMA) as the soft and hard monomers, and ammonium persulfate as the initiator. By changing the mass ratio of soft monomer and hard monomer in the formula, the effects of monomer ratio on the properties of waterborne acrylate were analyzed, including film-forming property, water absorption and the glass transition temperature as well as its transparency, smoothness, wear resistance and water resistance after coating. The film-forming property, transparency, smoothness and wear resistance of the waterborne varnish were optimal when the soft and hard monomer ratio was 17∶13~2∶3 (close to 1∶1) due to the interactions between hydrophobic and hydrophilic groups. The environment friendly waterborne vanish synthesized by the experiment had excellent film-forming property and transparency, which could meet the comprehensive performance requirements for coating of print and paper packaging materials. |
