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.

Description

technical field [0001] The invention relates to the field of paper, in particular to a waterproof and antibacterial paper. Background technique [0002] With the rapid development of the packaging industry, the safety of packaging paper has been widely valued. Compared with traditional packaging paper, antibacterial packaging paper is a new type of packaging paper. At present, most antibacterial paper antibacterial agents are distributed in The surface of the paper sample is easy to dissolve or migrate to the surface of the packaged food, and long-term use will still have a certain impact on human health. Therefore, the use of harmless antibacterial agents and technologies that can prolong the antibacterial time has become a research hotspot. Contents of the invention [0003] The object of the present invention is to provide a kind of waterproof and antibacterial paper aiming at the deficiencies in the above-mentioned prior art. [0004] To achieve the above object, the...
