Description

一种提高箱板纸印刷适应性的方法
技术领域
本发明涉及一种箱板纸制造工艺技术设备领域,特别涉及一种提高箱板纸印刷适应性的方法。
背景技术
随着商品流通渠道、产品销售形式及消费理念的变化,消费市场对包装纸板的使用性能提出了新的要求,尤其是用于高档包装如高档电子、电器、医药及彩印包装贴面工艺的包装。箱板纸在对内装物品进行完好保护的同时,还要具备良好的印刷适应性,确保箱体表面的印刷图案精美,起到产品宣传及促销功能。
印刷适应性是指承印材料能否良好地复制图像的一种性能,主要包括印刷图像的色彩密度、油墨传递性能及输出的平整性等,随着木材纤维的短缺,循环废纸回收利用率大大增加,箱板纸面层原料将采用废纸纤维取代部分木浆纤维进行挂面,而采用循环废纸纤维进行挂面的箱板纸由于其匀度、光泽度、平滑度、不透明度、吸收油墨性等比木浆挂面的纸种较差,严重影响了箱板纸的印刷适应性。因此,研究一种环保且能提高箱板纸的印刷适应性具有良好的经济和环保意义。
发明内容
本发明针对现有技术的不足,提供了一种提高成纸的匀度、平滑度、油墨吸收性、增加纸的表面强度、防止胶层的剥离并提高胶水粘度的提高箱板纸印刷适应性的方法。
本发明采用以下技术方案:一种提高箱板纸印刷适应性的方法,其特征在于,包括如下步骤:
1)将废旧箱板纸进行破碎打浆得到废纸浆,并在废纸浆中加入丙烯酸酯和丙烯腈-丁二烯-苯乙烯的混合物,加热至熔融状态并持续搅拌;
2)将步骤1)获得的浆料通过筛缝为0.1-0.15mm 的分级筛进行分级为长纤维浆料和短纤维浆料,使长纤维浆料和短纤维浆料相互分离;
3)在短纤维浆料中加入直径为0.2-0.3mm的玻璃纤维,并加入膨润土和聚丙烯酰胺的混合物,一起加热至熔融并持续搅拌制得初处理短纤维浆料,并用盘磨机对短纤维浆料进行盘磨处理得到处理后短纤维浆料;直接用盘磨机对长纤维浆料进行盘磨处理得到处理后长纤维浆料;
4)所述处理后短纤维浆料进入上层成形网,所述处理后长纤维浆料进入下层成形网 ;在上层和下层成形网前方的筛网进口处添加膨润土和聚丙烯酰胺的混合物,浆料在成形网上成形;
5)压榨烘干得到初步成纸;压榨部采用靴式压榨均匀脱水,通过控制压榨线压力,均匀脱除纸页中的水分,增加纸幅中纤维的结合力,提高原纸的紧度和强度并消除纸幅上的网印痕,提高原纸表面的平滑度并减少纸页的两面性;调节干燥部干燥曲线,严格控制成纸的含水量;
6)将初步成纸表面整平后摊开,对初步成纸表面进行施胶,干燥脱水后压光处理得到最终产品。压光部采用热油可控中高辊进行纸幅的整饰处理,增加成纸平滑度。热油温度为50摄氏度。
在步骤6)中,表面进行施胶后,表面的胶厚度为0.5-2mm;所述的胶的组分为:降解的淀粉5-10份(淀粉添加生物酶进行蒸煮加工得到)、消泡剂0.5-1份、N,N-亚甲基双丙烯酰胺0.2-0.5份、聚乙烯醇0.2-0.3份、烧碱0.2-0.3份;所述的胶调节pH至7.5-9。
在步骤3)中,玻璃纤维为二氧化硅或氧化铝;短纤维浆料、玻璃纤维、膨润土和聚丙烯酰胺的质量比为20:1:1:1。
废纸浆、丙烯酸酯和丙烯腈-丁二烯-苯乙烯的质量比为30:1:1。
步骤4)中,膨润土和聚丙烯酰胺的混合物的浓度为0.5-2g/cm3
在步骤5)和步骤6)的烘干或干燥过程中,温度不超过65摄氏度且大于40摄氏度。
本发明采用上述的方法,废纸浆中加入丙烯酸酯和丙烯腈-丁二烯-苯乙烯的混合物,提高了强度和耐候性;在短纤维浆料中加入直径为0.2-0.3mm的玻璃纤维,并加入膨润土和聚丙烯酰胺的混合物,提高了短纤维浆料的强度、匀度以及提高其之后在成形网的附着度;采用特定的胶组分,N,N-亚甲基双丙烯酰胺和聚乙烯醇提高了胶的粘性,防止胶从纸表面剥离。
