Water-based metal printing ink for lining paper for cigarettes and preparation method

Abstract

The invention relates to the technical field of printing and in particular relates to water-based metal printing ink for lining paper for cigarettes and a preparation method. The water-based metal printing ink is prepared from the following raw materials in percentage by weight: 15 percent to 35 percent of metal pigment, 50 percent to 70 percent of water-soluble resin, 20 percent to 50 percent ofmixed solvent, 0.5 percent to 3 percent of dispersant, 3 percent to 10 percent of surfactant, 0.1 percent to 0.3 percent of a de-foaming agent and 0.5 percent to 2.5 percent of adhesion promoter. After the water-based metal printing ink provided by the invention forms a film, the film has a good adhesive force; the water-based metal printing ink has a good printing effect and strong adaptability and can meet requirements of various actual printing requirements.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a water-based metallic ink used on cigarette lining paper and a preparation method thereof. Background technique [0002] The physical composite method used for the composite between the traditional metal material and the paper base, for example, the early gold aluminum foil and the paper base used adhesives and physical calendering, and a complete physical bond was formed between the paper base and the metal aluminum foil. At the interface, the composite mechanism between them is a mechanical composite. When the environmental conditions change or the adhesive fails, the metal aluminum foil and the paper base are prone to peeling or separation, resulting in the loss of the composite performance between the composite materials. ;The aluminum metal and the paper base in the vacuum aluminum plating method are a kind of compound at the molecular level between the plant fiber and the...

[0002] The physical composite method used for the composite between the traditional metal material and the paper base, for example, the early gold aluminum foil and the paper base used adhesives and physical calendering, and a complete physical bond was formed between the paper base and the metal aluminum foil. At the interface, the composite mechanism between them is a mechanical composite. When the environmental conditions change or the adhesive fails, the metal aluminum foil and the paper base are prone to peeling or separation, resulting in the loss of the composite performance between the composite materials. ;The aluminum metal and the paper base in the vacuum aluminum plating method are a kind of compound at the molecular level between the plant fiber and the aluminum molecule, which depends on the molecular surface adsorption force. This compound method is firm between the aluminum molecule and the fiber. break away

The problem is that the composite environment requires high temperature and vacuum state, the production cost is high, the composite area is not easy to change, and the processing method is single
