Electron beam (EB)-cured unsaturated vegetable oil and diacrylate was formulated as an alternative and green overprint varnish (OPV) for coatings in a finishing process. Linseed oil (LO) was applied with tripropylene glycol diacrylate (TPGDA) in different ratios to obtain EB-curable LO-based OPV (eLOPV). The eLOPV were irradiated by EB for curing using various absorbed doses of 10–100 kGy. Change of the functional groups, chemical structure and transition temperature of EB-cured eLOPV were characterized by FTIR, ¹³C-NMR and DSC. The curing efficacy was assessed by measuring conversion, gel fraction, swelling degree and by characterizing surface properties using solvent rub-test and cross-cut tape test methods. The EB-cured eLOPV exhibited great surface adhesion on substrates. The surface morphologies of the EB-cured eLOPV on papers and plywood sheets were observed by SEM. The results indicate that the eLOPV (LO-TPGDA blend 40: 60 w/w) was completely cured using EB at 30 kGy. Th optical properties were observed via yellowness and whiteness indexes according to ASTM E 313. Color difference and gloss value were measured using colorimeter and gloss meter, respectively. The eLOPV provide good surface qualities, i.e, good surface adhesion, low yellowness, homogeneous cured surface, high gloss value, and hydrophobic surface. Aiming at well-optimized formula and effective EB-curing process, the synthetic chemical can be reduced at least 50% w/w by using vegetable oil without photo-initiator. The utilization of LO and EB curing technology is a promising strategy for bio-/green-coatings approach.

电子束 (EB) 固化的不饱和植物油和二丙烯酸酯被配制成一种替代绿色罩光清漆 (OPV)，用于涂饰工艺中的涂层。将亚麻籽油 (LO) 与三丙二醇二丙烯酸酯 (TPGDA) 以不同的比例施用以获得 EB 可固化的 LO 基 OPV (eLOPV)。使用 10-100 kGy 的各种吸收剂量，用 EB 照射 eLOPV 进行固化。用 FTIR 表征了 EB 固化的 eLOPV 的官能团、化学结构和转变温度的变化，¹³C-NMR和DSC。通过测量转化率、凝胶分数、溶胀度和通过使用溶剂摩擦测试和横切胶带测试方法表征表面性质来评估固化效果。EB 固化的 eLOPV 在基材上表现出良好的表面附着力。通过 SEM 观察 EB 固化的 eLOPV 在纸和胶合板上的表面形貌。结果表明，eLOPV（LO-TPGDA 混合物 40:60 w/w）在 30 kGy 下使用 EB 完全固化。根据 ASTM E 313 通过黄度和白度指数观察光学性质。色差和光泽值分别使用色度计和光泽度计测量。eLOPV 提供良好的表面质量，即良好的表面附着力、低黄度、均匀的固化表面、高光泽值和疏水表面。针对优化的配方和有效的 EB 固化工艺，使用不含光引发剂的植物油可将合成化学品减少至少 50% w/w。LO 和 EB 固化技术的利用是生物/绿色涂料方法的一种有前途的策略。
