Problems solved by technology

There is a plastic release paper, that is, a layer of release agent (mainly silicone oil) is coated on the surface of the coated paper. Due to the use of polyolefin products, it is very difficult to treat paper with traditional recycling methods. In addition, due to the use of polyolefin products Low biodegradability and may also be harmful to the environment
Plastic-free release paper mainly includes glassine, CCK and other specially treated release papers. This type of release paper has the advantages of high smoothness, good oil resistance, and less release agent consumption during coating. The price is expensive, the supply of goods is in short supply, and it is difficult to meet the needs of production and economic benefits

Abstract

The invention discloses an antibacterial release paper and a production method thereof. The antibacterial release paper comprises a base paper layer, a pre-coated layer and an isolation layer; the pre-coated layer comprises, by weight, 8-13 parts of lipoic acid, 6-15 parts of zinc hyaluronate, 4-8 parts of chitosan, 8-15 parts of seaweed gel, 5-10 parts of sodium lignosulfonate and 5-10 parts of butyl acetate; and the isolation layer comprises, by weight, 10-15 parts of an aqueous polyvinyl alcohol solution, 7-10 parts of benzotriazole, 5-8 parts of ferric citrate, 4-6 parts of polyoxyethylenecastor oil and 5-8 parts of disodium hydrogen phosphate. The antibacterial release paper is produced by compounding the base paper layer, the pre-coated layer and the isolation layer, and has the characteristics of good antibacterial effect and high strength, and the antibacterial rate of the antibacterial release paper on Escherichia coli and Staphylococcus aureus is 99% or more; and the production method has the advantages of easily available raw materials, easiness in realizing production process conditions, low production cost, and facilitation of production.

Description

technical field [0001] The invention relates to a release paper, in particular to an antibacterial release paper and a preparation method thereof. Background technique [0002] Release paper, also known as silicone oil paper, anti-adhesive paper, mainly plays the role of isolating sticky objects, such as tape. It generally needs to be stripped and discarded when used. Release paper is generally divided into plastic release paper and plastic-free release paper. There is a plastic release paper, that is, a layer of release agent (mainly silicone oil) is coated on the surface of the coated paper. Due to the use of polyolefin products, it is very difficult to treat paper with traditional recycling methods. In addition, due to the use of polyolefin products It has low biodegradability and may also be harmful to the environment. Plastic-free release paper mainly includes glassine, CCK and other specially treated release papers. This type of release paper has the advantages of h...
