Abstract

The invention discloses special weather-resistant stain-resistant paint for a pop-top can. Raw materials of the special weather-resistant stain-resistant paint comprise the following components in parts by weight: 100 parts of fluorocarbon emulsion, 5 to 15 parts of acrylic emulsion, 5 to 15 parts of modified water-based epoxy resin, 2 to 10 parts of polyester resin, 5 to 10 parts of polycarbonate, 5 to 20 parts of polyurethane, 8 to 15 parts of hexafluoropropene trimer, 3 to 15 parts of rutile titanium dioxide, 2 to 5 parts of nano zinc oxide, 0.5 to 1 part of nano silver, 5 to 10 parts of nano calcium carbonate, 3 to 10 parts of mesoporous silicon dioxide, 2 to 10 parts of sea-foam stone powder, 2 to 8 parts of Kaolin, 0.1 to 1 part of organic silicon defoaming agent, 2 to 5 parts of starch, 5 to 10 parts of ethylene glycol, 2 to 8 parts of triethylene glycol monobutyl ether, 2.5 to 5.5 parts of triethylene glycol monoethyl ether, 2 to 6 parts of silane coupling agent and 50 to 80 parts of water. The special weather-resistant stain-resistant paint for the pop-top can is good in weather resistance, water resistance and stain resistance.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a special weather-resistant and stain-resistant coating for pop cans. Background technique [0002] Cans are widely used to hold milk, beverages, beer and other foods. Due to the poor chemical stability of metal materials, they are easily corroded under the action of acid, alkali, salt and humid air. Therefore, a layer of organic coating is generally applied on the surface of cans. layer, to prevent direct contact between the metal and the outside world, to avoid corrosion, but also prevent the penetration of harmful substances from the outside to the contents, and improve the shelf life of the filled food. However, the weather resistance and water resistance of the existing coatings for pop cans are not very satisfactory, and the stain resistance is not good, so they need to be modified. Contents of the invention [0003] Based on the technical problems in the background tec...
