1 ) 在基材上涂布底涂层;
2 ) 在底涂层上涂布转移涂层; 其中, 底涂层与转移涂层是连线式涂布。 其进一步技术方案为: 包括如下具体制作步骤:
1 ) 在基材上涂布底涂层, 进行预固化;
2 ) 在底涂层上涂布转移层, 进行固化;
3 ) 底涂层与转移层连线式涂布;
4 ) 进入烘箱后固化收卷。 其进一步技术方案为: 所述底涂层的生产工艺为: 预先对基材利用热风清除表面 所吸附的水分, 利用硅胶除尘辊清除基材表面的灰尘与异物、 离型离子风枪清除基材 表面所携带的静电, 然后再涂布底涂层, 同时做到预固化状态。 其进一步技术方案为: 在底涂层所涂布的转移涂层的厚度为 20nm至 200nm,选用 的材料是铂金催化加成型隔离剂、 非硅隔离剂, 固化温度 80 °C至 150 °C, 固化时间 15 秒钟至 2分钟。 其进一步技术方案为: 所述的底涂层的厚度为 20nm至 500nm,选用的材料为硅烷 偶联剂、 含羟基硅油、 乙烯基硅油、 有机硅体系防静电剂、 有机高分子导电聚合物溶 液, 固化温度 60 °C至 150 °C, 固化时间 3秒钟至 2分钟。 其进一步技术方案为: 所述的底涂层与转移涂层的连线涂布工艺, 所选用的工艺 过程如下: 基材放料经过前处理单元、 然后进入凹版涂布头后经过底涂烘箱后, 然后 再进入逗号涂布头, 再进入面胶烘箱, 最后收卷。 本发明与现有技术相比的有益效果是: 传统的热压转移膜, 离型膜 (即转移膜) 在油墨热压过程中会跟随油墨一起转移, 而本发明制作的载体膜在热压过程不随油墨 转移, 同时对转移后油墨表面影响最小, 其生产工艺参数为: 热压条件 180 °C, 时间 30s,压力 190ps i, 也优于传统的热压转移膜。传统的热压转移膜, 离型层会跟随转移, 导致后续转移过后在油墨表面无法再次进行印刷,比如贴合加强版等方面的后续加工。
