Description

Technical Field

[0001] The invention relates to a special coating for inner wall coating of aluminum kettles for military units, belonging to chemical coatings. Background Art

[0002] The inner wall of the military aluminum kettle needs to be treated with an inner coating. If it is not done or the treatment is not done well, it will be difficult to hold beverages or alcoholic items. During the process, some aluminum ions and harmful elements such as lead, cadmium, and arsenic will be precipitated, which seriously threatens the health of the soldiers. Through the proportion test, a professional beverage coating for the inner coating of aluminum kettles was developed. The coating has the characteristics of colorless and transparent, good adhesion, and paint surface. The advantages of uniformity successfully avoid the precipitation of aluminum ions and other harmful elements during the use of aluminum kettles, greatly improving The hygienic performance and drinking water safety of the kettle, therefore, the development of safe and hygienic environmentally friendly coatings is of great significance to improving the drinking water safety of aluminum kettles. Sex is of great significance, especially to the safety and health of soldiers. Summary of the invention

[0003] Main solution: 80 parts Preparation: Epoxy phenolic resin 40 parts 40 parts of dipropylene glycol methyl ether 7 parts of Ethylene glycol glycerol ether 5 parts of anhydrous ethanol 8 parts purified water Emulsification temperature: 90 degrees Stirring speed: 1600 rpm Emulsification time: 6 hours Curing agent Methyl ether amino resin: 9.8 parts Defoamer: 0.2 parts Ethanol: 6 parts Purified Water: 4 parts Curing temperature: 150 degrees Curing time: 40 minutes Compared with the prior art, the present invention has the following beneficial effects: Compared with traditional internal spray paint, the paint of the present invention has the advantages of being colorless and transparent, having good adhesion and uniform paint surface. It avoids the precipitation of aluminum ions and other harmful elements during the use of aluminum kettles, greatly improving the hygienic performance and Drinking water safety, therefore, the development of safe and hygienic environmentally friendly coatings is of great significance to improving the drinking water safety of aluminum kettles. In particular, the safety and health of military personnel is of great significance.

[0004] Specific embodiment The present invention is further described below in conjunction with specific embodiments.
