Problems solved by technology

Many commonly used metals are prone to corrosion, and the surface is easily stained, which affects the appearance
Metal aluminum, especially aluminum foil or aluminum film deposited on plastic or paper is soft in texture, poor in wear resistance and scratch resistance, and similar problems exist in aluminum alloy profiles, which need to be protected by coating

Abstract

The invention discloses a metallic paint which comprises the following raw materials in parts by mass: 1-4 parts of potassium hydroxide, 2-3 parts of benzotriazole, 1-2 parts of melamine, 2-6 parts of 12-hydroxystearic acid, 3-5 parts of methyl methacrylate, 2-5 parts of sodium lauryl sulfate, 3-7 parts of p-tert-pentyl phenol, 1-3 parts of tetraethylammonium tetrafluoroborate, 2-4 parts of benzyltriphenyl phosphorus chloride, 1-2 parts of trifluoroacetylacetone cobalt and 3-6 parts of methylene bromide. The metallic paint disclosed by the invention has the advantages of stable use effect, strong corrosion resistance, low surface damage tendency, favorable wear resistance and favorable punching property, can obviously prolong the service life, and is safe and nontoxic for the human body.

Description

technical field [0001] The invention belongs to the field of chemistry and chemical engineering, and in particular relates to a metal coating. Background technique [0002] One of the largest application markets for metal coatings is the coating of metal cans. Some two-piece aluminum alloy beverage cans use UV / EB coating technology. In the coating of food and beverage packaging cans, UV curing or EB curing coatings Showing strong advantages, fast curing, low volatility and low odor are its main characteristics suitable for this processing field. Three-piece food and beverage tubes made of tin-plated iron sheets (horse pockets) can also be coated with light-curing coatings for protection, or UV varnish after printing inks. The protection of metal copper parts tends to be coated with UV varnish instead of color paint, mainly to highlight the color and beautiful texture of metal copper itself. In addition, UV metal coatings are widely used in metal sign decoration, metal trim...
