进一步的，所述稀释剂为乙醇水溶液，所述乙醇水溶液的体积比为1：(30-40)。
进一步的，所述防潮剂为由氧化钙、铁粉、硅胶按照质量比10：(1-3)：(15-30)混合而成的混合物。
进一步的，所述热固性树脂为由酚醛树脂、环氧树脂、邻苯二甲二烯丙酯树脂以及不饱和聚酯按照质量比10：6：3：2混合组成的混合物。
上述的防水耐腐蚀纸箱的制备工艺，包括以下步骤：
1)将木浆100份与稀释剂30-45份混合均匀，加入聚乙烯蜡6-9份、甲壳素8-10份、热固性树脂15-20份、聚乳酸纤维1-3份、聚合氯化铝1-3份及防潮剂3-6份，加热，再次混合均匀，制得纸箱的木浆混料；
2)将混合均匀的木浆混料制成纸板；
