▎ 摘  要

NOVELTY - Bacteriostatic and deodorizing wet curtain paper comprises unbleached imported sulfate wood pulp board, graphene oxide modified phenolic resin, penetrant, aluminum sulfate, vegetable essential oil, diatomaceous earth, and silane coupling agent. USE - The bacteriostatic and deodorizing wet curtain paper is used in a transportation container (claimed). ADVANTAGE - The bacteriostatic and deodorizing wet curtain paper has high water absorption, high toughness, mildew resistance, prolonged shelf-life, and antibacterial and deodorizing properties. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing bacteriostatic and deodorizing wet curtain paper comprising (a) mixing the unbleached imported kraft wood pulp board, water and beating enzyme to process into a uniform slurry in a beating machine, (b) after adding aluminum sulfate to the slurry for mixing and reacting for 0.5-1 hour, adding the penetrant, continuously stirring uniformly, adding 0.5-1.5 wt.% silane coupling agent aqueous solution, heating at 50-60 degrees C, and stirring for 1-2 hours, adding diatomaceous earth and graphene oxide modified phenolic resin, raising the temperature to 70-75 degrees C, stirring for 2-4 hours to obtain a mixed slurry, (c) mixing the obtained mixed slurry, pressing, drying, and baking to obtain base paper, (d) adding the above-mentioned base paper on the plant essential oil for fumigation for 20-60 minutes, and leaving still for 4-12 hours to obtain wet curtain paper which is used in deodorizing wet curtain paper.
