Description
技术领域
本发明涉及包装纸领域，具体涉及一种利用气压支撑一次成型制备缓冲复合纸板的方法。
背景技术
为解决纸张原料大量消耗木材资源的问题，以无机矿物粉体微粒为主要原料的石头纸目前正在不断研究和开发利用。这种纸的生产过程中主要是以碳酸钙和少量聚烯烃类树脂为主，不仅可以解决纸浆原料问题，更重要的是这种原料无污染、易得，无需砍伐森林，在制造过程中无污染，达到了保护环境的目的。
目前石头纸技术不断提升，产品性能不断提高。随着石头纸产品的技术不断走向成熟，石头纸产品的应用对石头纸推广显得尤为重要。由于石头纸具有纸张和塑料的双重特性，且成本低、强度好、可防水防潮、阻隔性好，因此特别适合用于外包装。但由于石头纸原料影响，密度较大。通过借鉴传统瓦楞纸、蜂窝纸的形态，可以有效克服石头纸密度大的缺陷，使其在外包装得到了较好的应用。但由于石头纸加工性与传统纸完全不同，因此目前难以在传统瓦楞纸设备上进行加工。
中国发明专利CN102205668A公开了一种石头纸蜂窝纸板，利用石头纸热合的特性，利用传统蜂窝纸的原理，将石头纸预先压制成蜂窝状，通过热贴合得到了石头纸蜂窝纸板。该方法为石头纸应用于包装提供了较好地保证,但由于需要预先压制蜂窝状,然后高温加热进行贴合，工艺复杂。
中国发明专利CN104441870A公开了一种低密度石头纸及其制备方法，利用发泡母粒，经由挤出装置三层流道在模头模口处挤出成上中下三层叠加组合物，中间层采用发泡，得到低密度石头纸。但发泡纸由于缺少支撑，其刚性较差，无法作为纸板用于外包装。
发明内容
为了克服上述缺陷，本发明的目的在于提供一种具有缓冲功能复合纸板的制备方法，其特征是在挤出成型石头纸过程中,通过直接挤出贴合获得缓冲复合纸板。利用该方法获得的复合纸板牢固、具有缓冲的同时挺度较高，适用于制作各类外包装，特备适合用于纸箱。
一种利用气压支撑一次成型制备缓冲复合纸板的方法,其特征是制备方法如下：
（1）将石头纸的原料无机粉体、聚烯烃树脂、润滑剂、增白剂在100℃-120℃条件下混合，使润滑剂完全熔融，再经反应型螺杆挤出机于140-180℃温度条件下混炼挤出、模面切粒得到热塑性造纸用粒料；
（2）将步骤（1）得到的造纸用粒料送入单螺杆挤出机，挤出机设置T型模头，T型模头设定三层开口，上下层为“一”字型开口，中间层为若干“I”字型开口，在“I”字型开口间设置加气孔，造纸用粒料经挤出机熔融后由T型模头挤出，中间层“I”字型开口在出气孔气压支撑下形成垂直支撑筋条，通过调整贴合辊的间距，将上下层趁热贴合，形成中间为垂直筋条支撑，上下为面层贴合的复合纸板；
（3）将步骤（2）贴合的复合纸板通过牵引拉伸和四组伺服镜面辊筒平行贴辊冷却平整，辊间距的设置以平整复合纸板为准，不需要过度挤压，经平整、切边、分切，得到一种缓冲复合纸板。
优选地，步骤（1）所述的无机粉体、聚烯烃树脂、润滑剂、增白剂的重量份分别为：75-85份、10-15份、2-3份、0-3份。
优选地，步骤（1）所述的无机粉体为碳酸钙、硫酸钙、硫酸钡、云母粉、氧化锌、白云石粉、滑石粉、二氧化硅、高岭土、硅藻土中的至少一种。
优选地，步骤（1）所述的聚烯烃树脂为聚苯乙烯、高密度聚乙烯、聚3-羟基丁酸酯、聚3-羟基戊酸酯、聚丁二酸-丁二醇酯、聚己内酯、聚乳酸中的至少一种。
优选地，步骤（1）所述的润滑剂为聚乙烯蜡、聚丙烯蜡、乙撑双硬脂酸酰胺、硬脂酸酰胺、白油中的至少一种。
优选地，步骤（1）所述的增白剂为钛白粉、立德粉中的至少一种。
优选地，步骤（2）所述的加气孔气压控制在300-500pa之间，通过气压辅助，使垂直薄层处于垂直状态，并与上下面层贴合。
进一步，步骤（2）所述的T型模头的模口根据需要设置三层以上，由上向下依次设置为： “一”字型-“I”字型-“一”字型-“I”字型-“一”字型结构，得到五层缓冲复合纸板。
一种利用气压支撑一次成型制备缓冲复合纸板的方法，通过在石头纸挤出成型过程中设置均匀排布的“I”字型出料口，在出气孔气压支撑和冷却作中间层由均匀排布的“I”字型筋条支撑，具有良好的耐破强度和边压强度。特别是只通过模口设置可以根据需要制备三层、五层、七层以及七层以上的缓冲复合纸板，大幅简化了石头纸制备纸板的工艺流程。经贴合后的复合纸板处于高弹态，通过纵向拉伸变薄，可根据需要调整牵引速度，得到不同厚度的复合纸板。
本发明一种利用气压支撑一次成型制备缓冲复合纸板的方法，与现有技术相比突出的特点和有益的效果在于：
1、通过在T型模头设置“I”字型出料孔，在共挤过程中利用气压支撑下形成垂直支撑的薄层，上下层趁热贴合，形成中间为垂直筋条支撑的缓冲复合纸板。提升了缓冲复合纸的抗压性能。
2、通过在T型模头设置“一”字型、“I”字型相间的多层模口，制备出三层及三层以上复合的不同厚度的复合纸板，为石头纸在包装领域的推广使用提供了可靠地支撑。
3、该制备方法工艺简化，只需要在传统T型模头设置 “一”字型与“I”字型相间的模口，“I”字型模口间设置气孔即可实现不同层复合的缓冲纸板，大幅简化了工艺，提高了效率。
