Abstract

The invention provides anti-bacterial oil-proof paper and a preparation method thereof. The preparation method comprises the following steps: (1) adding zein into water so as to prepare a gelatinizedzein solution; (2) dissolving Konjak refined powder, Artemisia sphaerocephala Krasch gum, edible polyvinylpyrrolidone, propolis powder and waterborne stearic acid in remained water, carrying out uniform mixing under stirring, and carrying out standing for 2 h or above; (3) adding the mixed solution obtained in the step (2), tributyl citrate, glyceryl triacetate, Nostoc Sphaeroids Kutz polysaccharide and Porphyridium cruentum polysaccharide into the gelatinized zein solution, and carrying out uniform mixing under stirring; and (4) coating a surface sizing agent onto base paper with a surface sizing machine, drying paper at a temperature of 100 DEG C, then calendering the sized paper, and carrying out drying so as to balance moisture. The anti-bacterial oil-proof paper provided by the invention has oil-proof performance and antibacterial performance.

Description

technical field [0001] The invention relates to the field of greaseproof paper, in particular to an antibacterial greaseproof paper and a preparation method thereof. Background technique [0002] Grease-proof paper, also known as grease-resistant paper, is a type of paper that is resistant to penetration by oily substances, and is mainly used for oily food packaging. There are many ways to make paper oil-proof. One is to reduce the porosity by beating so that the paper has oil-proof performance. However, this method not only consumes a lot of energy, but also produces paper that is prone to seersucker paper defects; Coat a layer of continuous and dense organic polymer film on the surface of the paper. Coating materials include polyacrylate, polypropylene, polypropylene alcohol, carboxymethyl cellulose, etc., but this type of polymer film itself is not oil-resistant. At present, fluorine-containing oil-repellent agents are mostly used for surface sizing and coating. Fluorine...
