摘要:本研究对市售本色竹浆进行筛分，利用筛分出的粒径<0.6 mm的短小纤维竹浆与蒸油后的油樟渣浆配抄瓦楞原纸。结果表明，抄纸中加入25%针叶木浆、0.5%阳离子淀粉（CS）、0.4%阳离子聚丙烯酰氨（CPAM）和1.8%聚酰胺环氧氯丙烷树脂（PAE，质量分数9.5%），短小纤维竹浆（未打浆）与油樟渣浆按质量比10∶90配抄，未经熟化处理的纸张裂断长2.66 km，环压指数5.60 N·m/g，达到了瓦楞原纸GB/T 13023—2008合格品要求；当短小纤维竹浆打浆度35.8 °SR时，与油樟渣浆按照质量比30∶70配抄，并经110 ℃、15 min熟化处理，纸张裂断长4.75 km、环压指数8.24 N·m/g、耐破指数2.80 kPa·m²/g、耐折度15次，其中裂断长和环压指数均达到瓦楞原纸GB/T 13023—2008优等品要求，耐破指数和耐折度指标均达箱纸板GB/T 13024—2016合格品要求。

Abstract:In this study， the commercially available natural bamboo pulp was sieved， the short-fibre bamboo pulp with partide size<0.6 mm and oil evaporation of camphor residue pulp were selected to prepare corrugated medium. The results showed that when 25% soft wood pulp， 0.5% cationic starch （CS）， 0.4% cationic polyacrylamide （CPAM） ，and 1.8% polyamide epichlorol resin （PAE， concentration of 9.5%） were added， short-fibre bamboo pulp （unbeaten） and camphor residue pulp were used to prepare paper with the mass ratio of 10∶90 without cure treatmeut， the paper splitting length was 2.66 km， the cyclic compression index was 5.60 N·m/g， which met the requirements for the qualified products of GB/T 13023—2008.When the short-fibre bamboo pulp was beat to a degree of 35.8 °SR， and the camphor residue pulp was added with the mass ratio of 30∶70， after cure treatment 110 ℃ for 15 min， the paper was obtained with splitting length of 4.75 km， cyclic compression index of 8.24 N·m/g，breakage resistance index of 2.80 kPa·m²/g， folding resistance of 15， of which the splitting length and the cyclic compression index reached the requirements for the superior grade of GB/T 13023—2008 ， breakage resistance index and folding resistance indicators were up to the requirements for qualified products of GB/T 13024—2016.
