Abstract

The invention relates to a preparation method of a disposable antibacterial paper bowl. The preparation method of the disposable antibacterial paper bowl comprises the following steps of soaking raw fiber in sodium hydroxide solution into mixed fiber powder; mixing and pounding Chinese herb residues, and then boiling the pounded residues in ethanol solution into paste obtain a herb residue paste;uniformly mixing coagulated polysaccharides, sodium alginate and methylcellulose with water, keeping temperature in water bath to obtain a mixed adhesive; preparing and mixing chitosan solution and polyvinyl alcohol solution of a certain concentration, then adding in lactic streptococci nicin to obtain an antibacterial oil-proofing agent; uniformly mixing the mixed fiber powder, the herb residue paste and the mixed adhesive, and then hot-pressing the mixture into a bowl body; uniformly applying the antibacterial oil-proofing agent onto the inner surface of the bowl body, and performing dryingand cooling treatment to obtain the disposable antibacterial paper bowl. According to the preparation method of the disposable antibacterial paper bowl, the waste Chinese herb residues serve as the raw materials to produce the disposable antibacterial paper bowl to achieve high economic and ecological benefits; the prepared disposable antibacterial paper bowl is environmentally friendly and degradable and achieves excellent anti-oil and antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of disposable tableware production, in particular to a preparation method of a disposable antibacterial paper bowl. Background technique [0002] The traditional Chinese medicine industry is one of the traditional industries in my country. After the extraction of traditional Chinese medicine, a large amount of dregs will be produced.
