▎ 摘  要

NOVELTY - The corrugated paper board comprises a surface paper, a lining paper and a corrugated paper. The surface paper and the lining paper are adhered by an adhesive close to one side of the corrugated paper. The adhesive comprises 25-32 pts. wt. starch, 1-1.8 pts. wt. sodium hydroxide, 5-7 pts. wt. tannin, 0.8-1.4 pts. wt. polyether modified organic silicone surfactant, 0.005- 0.010 pt. wt. graphene oxide, 1-2.5 pts. wt. non-ionic penetrant, and 100-120 pts. wt. water. USE - Corrugated paper board. ADVANTAGE - The bonding strength of the corrugated board is improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a production method of corrugated paper board, which involves (1) uniformly mixing the raw materials of the adhesive, and stirring into slurry to form adhesive, (2) coating the adhesive on respective sides of the surface paper and the lining paper close to the corrugated paper, and (3) bonding the corrugated paper on one side of the lining paper coated with adhesive, adhering one side of the surface paper coated with adhesive on the corrugated paper, and drying.
