Abstract

Disclosed waterproof antibacterial paper comprises a paper layer and antibacterial waterproof layers. The paper layer employs any one of chrome paper, ivory board, grey board and brown paper, the antibacterial waterproof layer employs an antibacterial waterproof coating, and the waterproof antibacterial paper successively comprises the antibacterial waterproof layer, the paper layer and the antibacterial waterproof layer from top to bottom. The antibacterial waterproof coating comprises the following raw materials in percent by weight: 23-30% of an antibacterial material, 27-32% of an aqueous fluorocarbon emulsion, 0.3-0.6% of an aqueous disperser, 0.1-0.5% of an aqueous antifoaming agent, 0.2-0.3% of an aqueous levelling agent, 5-8% of ammonia water, and the balance being clear water. The antibacterial material is a mint and lemon microcapsule, wherein the wall material of the microcapsule is methoxypolyethylene-glycols-grafted chitosan. The waterproof antibacterial paper possesses antibacterial waterproof dual efficacies, and also the employed antibacterial material is a natural organic antibacterial material and is small in hazardness.
