输血袋用烫印箔及其制备方法
[1] 技术领域
[2] 本发明属于烫印材料技术领域， 具体涉及一种输血袋用烫印箔以及该烫印箔的 制备方法。
[3] 背景技术
[4] 目前， 一次性输血袋已被广泛应用到临床输血中， 相关的说明性内容则记载在 粘贴到输血袋外表面的不干胶标签上。 然而实践证明， 在输血袋上粘贴不干胶 标签的方法存在如下缺点： 不干胶标签容易受环境影响而遭到毁坏， 不能用于 有霉菌的环境； 不干胶标签可能会被撕毁并重新粘贴， 给血袋管理和输血安全 带来了非常大的不确定性。 此外， 不干胶还有可能会迁移到 PVC输血袋内， 从而 污染血浆。 但迄今为止， 国内外还未见有能够克服上述缺陷的印刷技术手段报 道。
[5] 发明人经过认真分析， 认为热烫印技术绿色环保、 操作简单、 印工精致且成本 低， 具有替代不干胶标签来标示输血袋的潜力。 然而， 输血袋特殊的使用环境 也给烫印材料提出了苛刻的要求： 不仅要求热转印油墨无毒无味， 无迁移性， 还要求烫印后字迹清晰牢固， 耐酒精擦拭， 耐高温蒸汽和环氧乙垸灭菌， 并适 宜低温保存 （血浆需要在 -22°C低温储存） 。
[6] 发明内容
[7] 本发明的目的是为了提供一种输血袋用烫印箔， 为输血袋应用热烫印技术呈现 标示信息提供了必要的物质基础， 烫印后的图文能够满足输血袋对安全性、 耐 候性、 耐化学试剂性的要求。 本发明还提供了输血袋用烫印箔的制备方法。
[8] 为实现上述目的， 本发明釆用的技术方案为： 输血袋用烫印箔， 由带基和依次 附着在带基上的脱离层、 颜色层组成， 所述颜色层由下述重量份的原料制成： 环氧树脂 20~40份、 填充料 30~35份、 颜料 30~45份。
[9] 所述脱离层由下述重量份的原料制成： CPP (氯化聚丙烯） 树脂 93~97份、 聚 丙烯蜡 3~7份。 [10] 所述环氧树脂的软化点在 90~110°C， CPP树脂的氯含量为 20~30%。
[11] 所述填充料为滑石粉。
所述带基是厚度为 10~12μηι的双向拉伸 PET (聚对苯二甲酸乙二醇酯） 膜， 有较高的强度； 所述脱离层厚度为 0.5~1μηι， 颜色层厚度为 3~4μηι。
[13] 输血袋用烫印箔的制备方法， 包括两个步骤： 1) 制脱离层， 2) 制颜色层； 步 骤 2) 的操作为： 按比例称取环氧树脂、 填充料和颜料； 用丁酮和二甲苯组成的 混合溶剂将环氧树脂溶解， 加入填充料和颜料后进行研磨， 混合均匀后形成颜 色层涂布液； 将颜色层涂布液涂布于脱离层上， 烘干即成输血袋用烫印箔。
[14] 所述丁酮、 二甲苯以及环氧树脂的重量比为 2~3： 2-3： 1。
釆用所述的 CPP树脂和聚丙烯蜡制脱离层吋， 步骤 1) 的操作为： 用甲苯将 CPP 树脂完全溶解后， 加入聚丙烯蜡混合均匀制成脱离层涂布液， 甲苯与 CPP树脂的 重量比为 9: 1； 将脱离层涂布液涂布到带基上， 烘干即成脱离层。
[16] 步骤 2) 中研磨后颜色层涂布液的细度小于 3μηι， 25°C下用涂 4号杯测颜色层涂 布液的黏度为 14~16s。
[17] 步骤 1) 中脱离层的烘干温度与步骤 2) 中颜色层的烘干温度均为 80~100°C。
[18] 在本发明的烫印箔中， 颜色层连接料选用的是环氧树脂， 该树脂无毒无味、 透 明性好， 并且具有很好的耐候性。 脱离层中的 CPP树脂结构稳定不迁移， 不仅能 够经受住酒精、 高温蒸汽及环氧乙垸等化学试剂的考验， 同吋也能够在 -22°C的 低温下长期使用。 聚丙烯蜡与 CPP树脂具有相似的结构， 用在脱离层中能够提高 烫印箔受热吋的脱离完整性， 使得转印速度快而不粘带、 烫印图文清晰完整。 制备方法中脱离层与颜色层形成均釆用的是冷涂工艺， 简单易操作， 生产成本 低。
[19] 本发明的输血袋用烫印箔的诞生为输血器材的表面标示带来了一次革命， 与传 统不干胶标签相比， 烫印图文更为牢固、 环保， 具有更优越的耐候性和耐化学 试剂性。
