Description
—种Mg/m2超薄高透明度拷贝纸的生产方法
技术领域
[0001]本发明涉及造纸领域，尤其涉及一种14g/m2超薄高透明度拷贝纸的生产方法。
背景技术
[0002]目前市场上客户都是用17-21g/m2半透明纸来包装，有客户提出是否能做高透明 度拷贝纸替代半透明纸。因为半透明纸是由定量17-21g/m2拷贝纸经十二辊超级压光机压 光而来，其中要经过湿润、压光等工序，成品率降低。如果在纸机上直接抄造出低定量高透 明度拷贝纸，不经过压光，透明度能达到压光后半透明纸的透明度，从而替代半透明纸的使 用，能省掉一道工序，节省人力、财力，降低成本，也为客户节约了产品的包装成本，市场前 景良好。然而，现有技术的低克重的拷贝纸由于生产工艺上的缺陷，制得的低克重拷贝纸性 能不佳，透明度不高，纸张抗张强度不高，无法达到国家标准。
发明内容
[0003]因此，针对以上内容，本发明提供一种14g/m2超薄高透明度拷贝纸的生产方法，解 决现有技术的低克重拷贝纸由于生产工艺存在的缺陷导致纸张透明度不高、抗张强度低的 缺陷。
[0004]为达到上述目的，本发明是通过以下技术方案实现的：一种148/1!12超薄高透明度 拷贝纸的生产方法，包括以下制备步骤：
[0005] (1)原料浆的选择：废纸脱墨浆与针叶木商品浆板按40〜55:45〜60的重量比混 合，作为原料浆；
[0006] ⑵准备辅料:所述辅料由纤维素酶、半纤维素酶、钛白粉、干酪素、阳离子淀粉组 成；
[0007] ⑶将步骤⑴的原料浆与步骤(2)的纤维素酶、半纤维素酶按1〇〇: 1〇〜25的重量 比混合，调制为原料浆，接着进行打浆、磨浆，再添加其他辅料进行加工处理，然后将其加入 水调制成上网浓度为0.3〜0 • 5 %的上网浆料，经长网脱水、压榨脱水、烘千;所述磨浆过程 中添加有水性丙烯酸树脂；
[0008] (4)浸渍:将步骤（3)处理得到的物料送入浸渍池中浸泡处理，所述浸渍池中添加 有浸渍液，所述浸渍液包含2〜35份的二磺酸钠盐。
[0009] 进一步的改进是:所述丙烯酸树脂的用量为原料浆重的3〜10%。
[0010] 进一步的改进是:所述磨浆过程中还添加有磨浆助剂。
[0011] 进一步的改进是:所述磨浆助剂为乙醇与氢氧化钠。
[0012] 进一步的改进是:步骤⑷中浸渍液与物料的重量比为20〜40:1。
[0013]进一步的改进是:步骤⑶中磨浆时先添加乙醇搅拌均匀后再加入氢氧化钠搅拌， 反应30min后再采用磨片研磨。
[0014] 进一步的改进是:所述磨片为安德里斯267ASS205A型。
[0015]通过采用前述技术方案，本发明的有益效果是:本发明的I4g/m2超薄高透明度拷 W纸的生产方法，包括以下制备步骤：（1)原料浆的选择:废纸脱墨浆与针叶木商品浆板按 40〜55:45〜60的重量比混合，作为原料浆;并且定量从17g/m2降到14g/m2,吨纸的使用面 积大大提高了，并且节约了木材资源、减少污染、降低能耗和降低成本，产品具有环保概念， 产品质量指标基本达到14g/m2拷贝纸的国家标准;辅料由纤维素酶、半纤维素酶、钛白粉、 干酪素、阳离子淀粉组成，辅料中的纤维素酶和半纤维素酶添加到原料浆中再进行打浆，通 过对纤维内部进行分解，促进磨浆过程中纤维的分丝和帚化，使打浆变得更容易，节省打浆 能耗;通过对纤维表面进行改性，对纤维末端进行分化，促进纤维的润胀，同时使纤维表面 和末端的羟基和羧基增多，从而增强纤维之间的结合力，达到增强成纸性能、提高成纸品质 的效果;在磨浆过程中添加有水性丙烯酸树脂，可以增加透明度，在烘干后进行浸渍处理， 处理液中含有二磺酸钠盐，可以进一步提高纸张的透明度。另外，本发明不需要经过压 光处理即可达到国家标准，节省了压光工序，降低了成本。
