Description

说 明 书
一种无溶剂硅油超薄离型纸及其制作方法 技术领域
本发明涉及一种应用在纸尿片、 卫生巾、 护垫上的无溶剂硅油超薄 离型纸， 具体涉及一种无溶剂硅油超薄离型纸及其制作方法。
背景技术
离型纸又称为隔离纸、 防粘纸， 在人们的生活、 工业用纸上应用十 分广泛， 现有的离型纸分为溶剂硅油、 无溶剂硅油等离型纸， 其中溶剂 硅油离型纸包括三层由上至下分别为原纸层、 底涂层、 溶剂硅油层， 在 原纸层的上表面还印刷有图案。 其重量平均为大于 35克 /平方米， 其溶 剂硅油层底部为光滑面， 平滑度小于 200S , 原纸层上表面的非光滑面 (即印刷面） 的平滑度为大于 60S。 该离型纸整体的重量大， 生产成本 高， 不能符合市场的需求。
进一步， 现有的无溶剂硅油离型纸在加工过程中， 须在原纸上涂上 化工原料底涂，而原纸克重高、平滑度低，需要进行至少一次超压以后， 才能在其上涂上无溶剂硅油层， 由于多出超压此道工序， 加工过程较为 复杂、 生产效率低。
因此有必要在现有离型纸的基础上设计出一种新结构的离型纸。 发明内容
本发明所要解决的问题是， 针对上述技术的不足， 设计出一种结构 简单、外形美观、超薄、节省成本且利于生产的无溶剂硅油超薄离型纸。
本发明为解决其问题所采用的技术方案是： 一种无溶剂硅油超薄离型纸，包括由上至下分别为原纸层、底涂层、 硅油层， 在原纸层的上表面还印刷有图案， 其特征在于： 所述原纸层的 重量为 18~28克 /平方米， 所述硅油层为无溶剂硅油。
上述技术方案还有以下改进技术方案： 所述离型纸的重量为 20~30 克 /平方米。 所述底涂层为聚乙烯醇与丁苯乳胶的混合物。 聚乙烯醇与 丁苯乳胶的混合比例为 8〜9： 2~1。
一种无溶剂硅油超薄离型纸的制作方法， 包括以下步骤：
步骤一， 准备原纸， 所述原纸的重量为 18~28克每平方米； 步骤二， 在原纸上涂上底涂层， 所述底涂层为聚乙烯醇与丁苯乳胶 的混合物；
步骤三， 在底涂层上涂上无溶剂硅油。
进一步， 所述底涂层采用四辊吻式涂布的方式进行涂布。
进一步， 所述无溶剂硅油采用网纹辊涂布的方式进行涂布。
本发明的有益效果是： 与传统离型纸相比本发明具有以下优点： 1、 本发明在同等面积下重量低， 节省原料， 达到了节能的目的； 2、 无溶 剂硅油不存在汽油、 甲苯等溶剂， 杜绝了生产过程中出现自燃自爆等现 象， 环保无污染， 符合国家和市场的需求； 3、 由于原纸层足够薄， 在 生产过程中无需对其进行超压， 减少加工工序， 提高了加工效率， 降低 生产成本。
附图说明
下面结合附图和实施例对本发明作进一步说明：
图 1为本实施例的结构示意图。 具体实施方式
