摘要:通过打浆处理、化学品的选择和使用对美纹纸层间剥离强度的影响进行探讨，寻找经济可行的方法来提升美纹纸层间剥离强度。实验结果表明，添加用量0.5%（相对于绝干浆）的环氧氯丙烷树脂（PAE）对美纹纸的层间剥离强度有一定的促进作用；阳离子淀粉可以显著提高美纹纸的层间剥离强度，但成纸较硬，对美纹纸的使用造成负面影响；在PAE用量0.5%的体系中，添加两性聚丙烯酰胺（ACPAM）或羧甲基纤维素（CMC）均有利于美纹纸层间剥离强度的提升，混合添加ACPAM和CMC比分别添加ACPAM或CMC更经济可行；适当调整打浆工艺，添加用量0.05%的ACPAM和用量0.05%的CMC，美纹纸的层间剥离强度可以提升34.8%；添加用量0.05%的ACPAM和用量0.10%的CMC，美纹纸的层间剥离强度可以提升50.6%。
Abstract:The influences of beating process and chemicals on interlayer peel strength of masking tape paper were investigated. The results showed that adding 0.5% PAE had certain increase of interlayer peel strength of masking tape paper. Cationic starch application had a negative impact on the masking tape paper due to the paper became harder although the interlayer peel strength was improved significantly. ACPAM or CMC added in the system containing PAE was benefit to the raise of the interlayer peel strength adding ACPAM and CMC together was more economic compared with separately adding ACPAM or CMC. Based on properly adjusted beating process, adding 0.05% ACPAM and 0.05% CMC, the interlayer peel strength of masking tape paper increased by 34.8%, achieved the average quality level of imported high-grade masking tape paper; Adding 0.05% ACPAM and 0.10% CMC, the interlayer peel strength of masking tape paper increased by 50.6%, more than part of the imported high-grade masking tape paper.
