| 目的 探究不同成膜助剂分子结构对聚氨酯丙烯酸酯（PUA）木器油墨墨膜性能的影响。方法 以成膜助剂作为研究对象，使用PUA作为连接料，与消泡剂等助剂一起制备木器油墨。研究成膜助剂3-甲氧基-3-甲基-1-丁醇、乙二醇丁醚、丙二醇、二乙二醇丁醚和二丙二醇丁醚对PUA木器油墨性能的影响。采用FTIR研究成膜助剂/连接料复合乳液薄膜的化学结构，并对其硬度、附着力、接触角表面性质进行表征。结果 助剂相对分子质量越小，墨膜硬度、附着力越大。当乙二醇丁醚的质量分数为4%时，硬度最大为3H，附着力为最佳等级0；醚键和羟基的相对含量越多则其硬度、附着力和接触角越大，丙二醇质量分数为4%时接触角最大（95.3°）。结论 选择质量分数为4%的丙二醇作为成膜助剂时，综合性能最佳；选择成膜助剂时应优先考虑相对分子质量小、极性基团相对含量多的助剂。 |

| The work aims to investigate the effects of molecular structure of different film-forming additives on the properties of PUA ink film for wood inks. With film-forming additive as research object and PUA as linking agent, wood inks were prepared with defoamer and other additives. The effects of film-forming additives 3-methoxy- 3-methyl-1-butanol, ethylene glycol butyl ether, propylene glycol, diethylene glycol butyl ether and dipropylene glycol butyl ether on the properties of PUA wood inks were studied. FTIR was used to study the chemical structure of film-forming additive/binder composite emulsion film, and its hardness, adhesion and contact angle surface properties were characterized. The smaller the relative molecular weight of the additives, the greater the hardness and adhesion of the ink film. When the mass fraction of ethylene glycol butyl ether was 4%, the maximum hardness was 3H and the best adhesion was 0. The higher the relative content of ether bond and hydroxyl, the greater the hardness, adhesion and contact angle. When the mass fraction of propylene glycol was 4%, the contact angle was the maximal (95.3°). When the propylene glycol with mass fraction of 4% is selected as the film-forming additive, the comprehensive property is the best. The additives with small molecular weight and high polar group content should be given priority to in the selection of film-forming additives. |
