摘要
本研究以未漂阔叶木浆为原料,在最适打浆度(70°SR)下制备定量为60 g/m^(2)的防油原纸,通过表面涂布TEMPO氧化纳米纤维素(TCNF)和壳聚糖(CTS)的方法,提高纸张的防油性能,探究不同涂布量对纸张防油等级、耐热油性能、防溶剂性能、纸张物理性能的影响。结果表明,双层涂布TCNF和CTS,涂布量分别为2.5和1.4 g/m^(2)时,纸张达到最高防油等级(12级),且纸张具有较好的耐热油和防溶剂性能,透气度0.003μm/(Pa·s),厚度为106μm。
In this study,unbleached hardwood pulp as raw material,oil-proof base paper with 60 g/m^(2) was prepared under the circumstance of optimal beating degree(70°SR). The oil-proof performance of the paper was improved by coating TEMPO-oxidized cellulose nanofibril(TCNF)and chitosan(CTS). The effects on different amount of coating with oil-proof grade,hot oil resistance,solvent resistance and physical properties were also explored. The results showed that when the amount of coating of TCNF and CTS were 2.5 g/m^(2) and 1. 4 g/m^(2) respectively,the oil-proof grade of paper reached the peak(grade 12)and the paper had excellent hot oil resistance,solvent resistance. Air permeability and thickness of paper was 0. 003 μm/(Pa·s) and 106 μm, respectively.
