Rust-proof metal printing ink containing pepper essential oil

Abstract

The invention relates to the field of printing ink, and particularly relates to rust-proof metal printing ink which contains pepper essential oil. The rust-proof metal printing ink is prepared from the following raw materials in parts by weight: 0.01-0.02 part of propyl hydroxybenzoate, 1-2 parts of monoalkyl ether phosphate potassium salt, 1-3 parts of casein, 0.001-0.002 part of the pepper essential oil, 0.5-2 parts of hydrogenated polydecene, 25-35 parts of water-based polyurethane-acrylate composite emulsions with solid content of 50%-60%, 1-2 parts of cetyl trimethyl ammonium chloride, 4-8 parts of isopropanol, 18-25 parts of deionized water, 6-12 parts of pigments and 1-2 parts of auxiliary agents. The rust-proof metal printing ink disclosed by the invention has high compatible binding capacity with resin through the addition of the casein treated through the monoalkyl ether phosphate potassium salt by taking the water-based polyurethane-acrylate composite emulsions as binding materials, can be used for improving the wettability and decorative effect of ink through the auxiliary agents, can be well attached to multiple metal surfaces, can prevent the erosion of worms and ants through specific smell of a pepper essential oil component, can be used for prolonging the oxidization of the metal surfaces and achieves the dual effects of decoration and base material protection.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to an antirust metal printing ink containing capsicum essential oil. Background technique [0002] Ink is a kind of coloring material that is very commonly used in daily life. It is used as the carrier of characters and patterns by printing. It is a viscous colloidal fluid. It is widely used in various printings such as books, periodicals, packaging and decoration, and architectural decoration. With the increase of social demand, the types and output of inks have also expanded and increased accordingly. Improving the performance of inks and achieving an energy-saving and efficient production mode is always an inevitable direction for the development of inks in the future. [0003] The factors that affect the performance of ink mainly lie in the performance of components such as pigments, linking materials, fillers and additives. For example, pigments affect the durability and tinting st...
