Abstract:The residues produced in the bamboo pulping process was used as the raw material， and the bamboo particles were prepared by crushing and grinding. The performance was analyzed， and the feasibility of using bamboo residues as filler for corrugated base paper was explored. The results showed that cellulose of bamboo exhibited type I structure， and the pyrolysis temperature was 236℃. The addition of bamboo filler had a positive effect on improving the ring crush index of paper， and its increase increased with the decrease of bamboo particle size. The optimal parameters of bamboo filler were as follows： particle size of 0.316 mm × 29.4 μm， addition amount of 15%. At this time， the retention rate of the filler was 61.4%， and the ring crush index and tensile index of the paper were 5.4 N·m/g and 12.1 N·m/g， respectively.The ring crush increasd 28.6% compared with without filling bamboo paper.
