Abstract

The invention discloses an antibacterial and mildew-proof barrier coating which is prepared from the following raw materials in percentage by weight: 34 to 36 percent of a water-based acrylic emulsion, 7 to 9 percent of nano cellulose, 1 to 3 percent of a water-based wax slurry, 6 to 8 percent of tourmaline, 4 to 6 percent of activated carbon, 2 to 4 percent of nano silver powder, 4 to 6 percent of hexacyclic stone powder and the balance of 34 to 36 percent of water and alcohol. The invention belongs to the field of package coating. Tourmaline, activated carbon, nano silver powder, hexacyclicstone powder and other raw materials are combined;tourmaline andhexacyclic stone powder are added, so that negative ions can be released, ionized surface water molecules are formed, vapor erosion is reduced, and nano silver powder hassurface antibacterial function; the water-based barrier coating disclosed by the invention has the advantages of low price, safety in use, resource and energy conservation and reduction of environmental pollution and public hazard, the compactness of the water-based barrier coating is better improved by adding of nano cellulose, and the water-based barrier coatingnot only has a shorter decomposition period than degradable plastics, but also is relatively low in cost.

Description

technical field [0001] The invention relates to the technical field of packaging coatings, in particular to an antibacterial and antifungal barrier coating. Background technique [0002] Packaging refers to wrapping the product with paper or putting the product into a carton or bottle. The packaging is to protect the product during circulation, facilitate storage and transportation, and promote sales. Containers, materials and auxiliary materials used according to certain technical methods, etc. It also refers to the operational activities of imposing certain technical methods in the process of using containers, materials and auxiliary materials to achieve the above-mentioned purposes. Marketing-type packaging focuses on planning strategies and becomes packaging in a broad sense. [0003] As people's calls for protecting the environment, caring for the earth, and saving resources are getting higher and higher, the requirements for product packaging are becoming more and more...
