| 目的 研究烘烤工艺对彩印覆膜铁材料拉深成形后光油产生裂纹、内壁透明膜白痕、蒸煮后覆膜剥离的影响规律。 方法 分别设定罩光油烘烤时间为 10， 12， 15 min， 分析烘烤时间差异对光油表征及耐加工性能的影响， 对比罐体烘烤前后的内壁白痕变化及耐蒸煮性差异。 结果 随着罩光油烘烤时间的延长， 彩印覆膜铁表面光油的耐加工性能得到了提升， 烘烤可以消除内壁透明膜白痕， 并避免覆膜在蒸煮后剥离 。 结论 将罩光油烘烤时间从 10 min 延长至 15 min， 可避免罐体拉深后的光油裂纹产生。 罐身成形后增加烘烤工艺（烘烤温度为 230 ℃， 烘烤时间为 1 min）可消除内壁透明膜白痕， 提高空罐的耐蒸煮性能。 |

| Objective To study the influence of baking on varnish cracks, the white marks of transparent inner film and film’ s peeling off after boiling. Methods By setting the varnish baking time as 10, 12 and 15 minutes respectively, the influence of difference baking time on varnish’ s representation and process resistance was analyzed. The changes in white marks of transparent inner film and the boiling resistance of baked cans were compared with non-baked ones. Results With the extension of overprint varnish baking time, the process resistance of surface varnish of printed laminated steel was improved. Baking was effective to remove the white marks of transparent inner film, and avoid film peeling after cooking. Conclusion It was found that extending the varnish baking time from 10 minutes to 15 minutes could effectively prevent varnish cracks after can-body drawing. Adding a 1 min baking step at 230 ℃ on can-body could remove the white marks, and improve the boiling resistance of the cans. |
