Description

一种环保型抗油脂纸的生产方法
技术领域
本发明涉及废纸制浆造纸技术领域，具体涉及一种环保型抗油脂纸的生产方法。
背景技术
抗油脂纸，也被称为防油纸，是指能防止油脂吸收渗透的纸。从狭义上讲，是指使用漂白、半漂白或未漂白化学木浆，并通过高度打浆处理而抄造的一类纸。也包括使用浆内添加或表面涂布防油剂、耐油涂料(干酪素型、清漆型、热熔或树脂型，硅酸盐型)涂布加工，而生产的能够抗拒油脂渗透和吸收的特种纸。近几年来大量发展表面张力很低的氟类化合物，采用浆内施胶和纸张表面施胶等方法处理的纸张有很好的防油效果。目前，采用全氟烷基化合物施胶制备的纸张在印刷、包装材料上已广泛应用。防油纸被广泛用于各类食品包装，蛋糕纸杯，防油纸袋，肯德基等各类食品包装。防油纸抗油脂渗透能力强，市场需求强劲。
制备抗油脂纸主要有两类方法，一类是依靠提高纸浆的打浆度，促进成纸“羊皮化”；另一类是采用加工纸的制备方法。采用提高打浆度的方法时，纸浆打浆度在80°SR以下，成纸的抗油脂性能几乎没有变化；打浆度在80°SR-85°SR之间，成纸的抗油脂性能随着打浆度的增加而增加；打浆度超过85°SR以后，抗油脂性能增长迅速。但成纸的撕裂强度随打浆度的增加而下降，耐破强度在88°SR以后也下降，打浆度愈高，电耗急剧上升，且打浆度升高，纸浆为粘状打浆，在网部的滤水性能很差，容易造成脱水困难，干燥后容易产生纸病，且成纸的平整性很差。因此仅仅依靠提高打浆度来生产抗油脂纸在实际生产中不可行，利用施胶的方法在浆内添加抗油剂或纸张表面施涂抗油脂涂料来配合，这样可降低浆料的打浆度，从而提高纸机的运行速度，降低能耗，且提高成纸的质量。利用抗油材料涂布浸渍纸张，或在纸张上层覆盖金属薄膜或塑料薄膜、或采用表面张力很低的化合物(如氟树脂)用于纸张表面的涂布，由浸润现象来看，凡表面张力大于这类化合物的液体均不能透过，从而达防止油脂渗透的目的。
现有技术中，抗油材料涂布浸渍纸张多是用石油基材料(如塑料薄膜或淋膜)与纸张复合而成，但这类纸塑包装材料存在难降解、难分离、难回收和易迁移的危害。近年来采用了含氟防油剂，在纸张上层覆盖一层具有防油效果的薄膜，虽解决可以降解，但是不仅价格昂贵，而且由氟引起的危害也不容小觑，已经越来越难以满足环保的要求。因此采用生物基材料代替石油基材料生产抗油脂纸已经成为行业发展的趋势。

S4、打浆、浆内施胶和抄纸，
准确称取1kg漂白针叶木桨板用水浸泡，待桨板充分润胀后，先用瓦利打浆机进行疏解，再以8％的浆浓在PFI磨浆机中进行磨浆，将纸浆打浆至45-50°SR将打浆好的浆料脱水，均匀分散放至密封袋中保存；称取已打好浆的针叶木浆料，以一定浓度在纤维分离器中进行疏解，将疏解后的浆料在纸页成型器中，然后加入1-2g步骤S1中制得改性松香树脂施胶剂，搅拌均匀后，脱水抄造成湿纸幅，湿纸幅经油压机压榨，最后将压榨后的纸页放入真空干燥器中干燥，以100℃的干燥温度干燥得到的施胶后定量为60±5g/m2的原纸，放在恒温恒湿室处理24h，用于后续处理；
S5、表面施胶，
将步骤S4中得到的原纸放入至表面施胶机中，通过表面施胶机将步骤S2中制备的阳离子壳聚糖表面施胶剂均匀的涂覆在原纸表面，控制施胶量为0.5-2g/m2，施胶完成后，将原纸送入至干燥器内干燥后备用；

性能测试：
1)纸张强度，按照TAPPI标准T494，T414和T403分别在抗张强度测定仪(L&W062，瑞典)、撕裂度仪(L&W009，瑞典)和耐破度测定仪(L&W180，瑞典)上测定纸张的抗张强度、撕裂度和耐破度，分别除以相应纸张的定量得到纸张的抗张指数、撕裂指数和耐破指数。
2)抗油脂值测试方法，采用目前防油纸及防油纸板工业通用的一种称为“油滴实验(Oil KitTest-TAPPIT559pm-96)”的国际测试方法。该方法采用不同表面张力的液体(见图2)，测定纸品的抗油脂性能。其测定步骤是：将每一种油从2.54cm(1in)的高度滴落到待测纸品上，15s后用干净的棉球轻轻的擦拭。油滴渗透到纸张内部会使其变暗表示抗油性能没有达到这种油滴代表的等级。没有产生渗透这一现象的最高编号代表被测纸品的抗油脂值。每组试样做5次平行试验，结果不相差0.5级，取平均值作为该纸品的抗油脂值。
3)生物降解率的测定，采用堆肥法，按照GB/T19277标准进行。

从表1中的实验数据可以看出，采用本方法获得的环保型抗油脂纸抗张强度、撕裂度、耐破度性能好，抗油脂值达到9-10级，满足包装纸的抗油要求，生物降解率也达到90％以上，可以生物降解，绿色环保。对比例1(未进行浆内施胶、表面施胶和表面涂布)中最终抄造得到的原纸的抗张强度、撕裂度、耐破度均较低，而且抗油脂值为1级，基本不具有抗油脂的能力，但是生物降解率最高。对比例2(未进行浆内施胶)获得纸张相比实施例1，抗张强度、撕裂度、耐破度、抗油脂值，均有所降低，生物降解率略有上升。通过实施例1-4和对比例1、对比例2的数据可以看出，采用本环保型抗油脂纸的生产方法通过浆内施胶、表面施胶和表面涂布相结合的方式，可以在较低打浆度下大大提高纸张的抗油脂性能，减少高打浆度对纸张抄造过程中带来的不良影响，采用的是浆内施胶剂、表面施胶剂和复合抗油脂涂料均采用环保材料，整体生物可降解，不会产生环境污染。此外，通过对浆内施胶剂、表面施胶剂和复合抗油脂涂料配方的优化设计，可以在保证生物可降解的前提下，提高纸张的抗油脂性能，并且提高纸张的抗张、抗撕裂和耐破强度。

具体数据如表2所示。
表2表面涂布对纸张强度及抗油脂值的影响实验数据
Figure BDA0002789055370000071
从表2中的实验数据可知，采用本配方制得的复合抗油脂涂料对原纸的抗油脂值的影响很大，对比实施例1和对比例3，未进行表面涂布的纸张的抗油脂值从10级降低至5级，并且不进行表面涂布的纸张已经难以满足包装纸抗油性能的要求(食品包装纸的抗油脂值的要求大于6级)。采用本方法获得的环保型抗油脂纸抗张强度、撕裂度、耐破度性能好，抗油脂值达到9-11级，满足包装纸的抗油要求，生物降解率也达到90％左右，可以生物降解，绿色环保。
以上所述为本发明的较佳实施例而已，但本发明不应局限于该实施例和附图所公开的内容，所以凡是不脱离本发明所公开的精神下完成的等效或修改，都落入本发明保护的范围。
