Abstract

本发明提供一种基于三层头箱单层网抄造的高松厚度铜版纸的制备方法，通过使用更多的机械浆从而突破铜版纸厚度瓶颈，成纸松厚度可高达1.2～1.4cm3/g，远远高于目前市售铜版纸的松厚度，且仍能维持铜版纸的高光泽度和细腻印刷面感。不仅可以使用更高制浆得率的机械浆，在相同的厚度条件下，也可以节降大约30％的原料消耗。

Description

一种基于三层头箱单层网抄造的高松厚度铜版纸的制备方法
技术领域
本发明涉及造纸技术领域，特别涉及一种基于三层头箱单层网抄造的高松厚度铜版纸的制备方法。
背景技术
铜版纸目前均采用单层网抄造，与多层网抄造的铜卡或白板纸不同，其有较高的光泽度和平滑度，面感较细腻，印刷图文精美，但因为只有单层网抄造，不能像多层网那样在芯层使用大量的机械浆，因此松厚度较低，一般均为1.0cm3/g以下，少量可以做到1.0～1.1cm3/g。松厚度是铜版纸的一项关键指标，较高的松厚度不仅可以获得较优的挺度等指标，同时因为在相同的厚度情况下具有较低的基重，意味着可以使用更少重量的原料而更加环保和经济性。
目前国内有关高松厚铜版纸生产的专利有：1.《CN110777553A-一种高松厚度高光泽双面铜版纸的抄造方法》，松厚度大于1.0cm3/g，平滑度＞600s，光泽度60％～70％，5个实施例松厚度均为1.00-1.05cm3/g；2.《CN201710366448-一种高松厚度铜版纸的制造方法》，松厚度为大于1.05cm3/g，具体为基重101gsm，厚度110μm，实际松厚度1.09μm，平滑度＞150s，光泽度＞20％；3.《CN101698985B》-一种高机械浆含量铜版纸的制造方法及其制得的铜版纸》，实施例松厚度1.04～1.06cm3/g，光泽度约82.5％。
发明内容
鉴以此，本发明提出一种基于三层头箱单层网抄造的高松厚度铜版纸的制备方法，来解决上述问题。
本发明的技术方案是这样实现的：基于三层头箱单层网抄造的高松厚度铜版纸的制备方法，包括以下步骤：
(1)配浆
芯层：纤维浆料由碱性过氧化氢机械浆(简称APMP，松厚度≥3.2cm3/g，游离度300～400ml)、漂白硫酸盐阔叶木浆(简称LBKP，游离度360～420ml)、漂白硫酸盐针叶木浆(简称NBKP，游离度400～460)按绝干重量比50～80:10～20:0～10制得，再往纤维浆料中加入填料、阳性淀粉、干强剂、聚合氯化铝(PAC)和烯基琥珀酸酐(ASA)；
面层和背层：纤维浆料由漂白硫酸盐阔叶木浆(LBKP)、漂白硫酸盐针叶木浆(NBKP)按绝干重量比70～100:0～30制得；再往纤维浆料中加入阳性淀粉、干强剂、烯基琥珀酸酐(ASA)、阳性高分子聚丙烯酰胺和胶体二氧化硅；
(2)头箱：三层浆料均控制浆浓1～2％，浆网速比1.02～1.05:1；
(3)压榨：两道靴式压榨，压榨线压950～1100kN/m，出压部干度为48～52％；
(4)前干燥：出前干燥水分控制6.0％～10.0％
(5)表面施胶：SAE(苯乙烯丙烯酸)类型表面上胶剂相对绝干酶切淀粉比例为10～20％(上胶剂原液重量相对绝干酶切淀粉重量比例)，胶液固含12～14％，黏度16±4cps，上胶量2～5gsm；
(6)硬压光：线压20～40KN/m，温度60～80℃；
(7)底涂涂布：采用膜转移涂布方式(MSP)，涂布量10～24gsm，固含60～68％，黏度500～800cps，颜料使用≤2um比例为55～60％的研磨碳酸钙，羧基丁苯胶乳相对颜料绝干量添加5～8％，生物胶乳相对颜料绝干量添加8～12％；
(8)中涂涂布：采用刮刀涂布，涂布量单次单面10-12g/m2，两面各涂一层。涂料固含65％～69％，粘度700～900cps。中涂涂料使用≤2um比例为65％研磨碳酸钙100％、丁苯胶乳相对颜料绝干量添加6-10％、生物胶乳相对颜料绝干量添加4-7％。
(9)面涂涂布：采用刮刀涂布，涂布量单次单面10-12g/m2，两面各涂一层。涂料固含68％～70％，粘度1000～1200cps。面涂涂料使用≤2um比例为98％研磨碳酸钙80％～100％、使用≤1um比例为90％瓷土0～20％，丁苯胶乳相对颜料绝干量添加8～12％。
(10)压光：采用2NIP(压区)超级压光方式，压光温度140-180℃，压光线压40-90KN/m。
进一步的，所述配浆中芯层基重为55～180gsm。
进一步的，所述配浆中面层和背层克重均为20～50gsm。
进一步的，所述配浆中芯层填料添加量为绝干浆料10％～30％，阳性淀粉相对绝干浆料添加5～15kg/t，干强剂相对绝干浆料添加5～15kg/t，聚合氯化铝相对绝干浆料添加1.0～2.0kg/t，烯基琥珀酸酐相对绝干浆料添加1.0-1.5kg/t。
进一步的，所述配浆中面层和背层阳性淀粉相对绝干浆料添加5～15kg/t，干强剂相对绝干浆料添加5～15kg/t，烯基琥珀酸酐相对绝干浆料添加1.0～1.5kg/t，添加阳性高分子聚丙烯酰胺50～100ppm和胶体二氧化硅2.0～4.0kg/t。
与现有技术相比，本发明的有益效果是：
本发明提供在单层夹网条件下，采用三层头箱抄造一种具有高松厚度且不影响表面印刷细腻度的铜版纸的抄造工艺。
本发明原纸采用单层夹网抄造，但与一般铜版纸采用单层头箱不同的是采用了三层头箱，可以在头箱芯层添加较高比例的机械浆达到较高的目标松厚度，同时头箱面层和背层采用纯化学浆，相比一般高松厚度铜版纸原纸表面有较少或没有机械浆，可以提供更平滑细腻的原纸表面确保铜版纸具有较优的印刷细腻度和光泽度，可以降低压光线压减少压光带来的厚度损失从而提高松厚度。而与多层网抄造的铜卡或白板纸不同，铜卡或白板纸采用多个头箱+多层网，而本发明采用三层头箱(只有一个头箱，喷出3层浆料)+单层网(只有一层)的方式。
本发明原纸浆内添加1.0-1.5kg/t的ASA，同时表面先涂一层酶切淀粉+SAE表面上胶剂混合胶液，确保原纸抗水性和减少后段涂布时涂料的迁移。
本发明采用低温低压的硬压光方式对原纸平整性进行修饰，修饰的同时减少压光厚度损失。
表面涂布先采用1个MSP涂布对原纸两面各涂一层打底，然后采用4个刮刀涂布对两面分别再涂2次涂料，最后采用2NIP超压方式对成纸表面PPS和光泽度进行修饰，提高最终铜版纸表面的细腻度。
本发明生产的铜版纸松厚度可达到目前市面铜版纸所没有的1.2～1.4cm3/g松厚度，同时粗糙度≤1.4μm，光泽度60～70％，定量为150～350gsm。
本发明可以通过使用更多的机械浆从而突破铜版纸厚度瓶颈，成纸松厚度可高达1.2～1.4cm3/g，远远高于目前市售铜版纸的松厚度(约0.8～0.9cm3/g)，且仍能维持铜版纸的高光泽度和细腻印刷面感。不仅可以使用更高制浆得率的机械浆，在相同的厚度条件下，也可以节降至少30％以上的原料消耗。
