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.
