A special corrosion-resistant and weather-resistant coating for pop-top cans

Abstract

The invention discloses corrosion-resistant and weatherproof paint specially used for a pop can. Raw materials of the corrosion-resistant and weatherproof paint specially used for the pop can are as follows in parts by weight: 100 parts of acrylic emulsion, 20-35 parts of epoxy resin emulsion, 2-10 parts of waterborne polyaniline solution, 3-8 parts of terpene resin, 10-25 parts of titanium dioxide, 10-20 parts of talcum powder, 15-20 parts of light calcium carbonate, 2-8 parts of precipitated barium sulphate, 2-10 parts of mica powder, 3-15 parts of zinc oxide, 2-10 parts of nanosilicon dioxide, 10-25 parts of modified graphene oxide, 1-5 parts of zinc phosphate, 3-10 parts of iron oxide red, 1-2 parts of a dispersing agent, 0.5-1.5 parts of a thickening agent, 3-10 parts of a coalescing agent, 0.5-2 parts of 2-amino-2-methyl-1-propanol and 20-50 parts of water. The corrosion-resistant and weatherproof paint specially used for the pop can, disclosed by the invention, has good weatherproof property and excellent corrosion resistance and also has certain antibacterial property.

Description

technical field

[0001] The invention relates to the technical field of coatings, in particular to a special corrosion-resistant and weather-resistant coating for pop cans. Background technique

[0002] Cans have the advantages of light weight, small size, not easy to break, and easy to carry. They have been widely used to hold milk, beverages, beer and other foods. Due to the poor chemical stability of metal materials, they are easy to break under the action of acid, alkali, salt and humid air. Therefore, a layer of organic coating is generally applied on the surface of cans to prevent direct contact between the metal and the outside world and avoid corrosion. It also prevents the penetration of harmful substances from the outside into the contents and improves the filling of food. shelf life. With the development of society, people have put forward higher requirements on the performance of the coatings used for pop cans. The corrosion resistance and weather resistance of t...
