Problems solved by technology

[0003] There are also a few ink manufacturers in China that produce water-based gold inks, but they are all produced with imported water-based copper-gold powder or water-based gold paste. The cost of production materials is high and the source of materials is unstable.

Abstract

The invention discloses water-based golden ink produced by using ordinary bronze powder. The ink is prepared from the following raw materials in parts by weight: 30-55 parts of pre-prepared resin liquid, 0-10 parts of water-based color paste, 10-60 parts of pre-prepared gold paste, 0-5 parts of anti-scraping agent, 0.1-1 part of water-based defoaming agent, 0.2-2 parts of water-based lubricant, 1-10 parts of water and 1-30 parts of alcohol solvent. The preparation method comprises steps of preparing the pre-prepared resin liquid, preparing the pre-prepared gold paste, mixing, dispersing and tempering. The effects of imported water-based golden ink can be achieved by using ordinary bronze powder produced in China, and the ink is low in price, stable in material resource, good in metal effect and good in storage stability.

Description

technical field [0001] The invention relates to a printing ink and a preparation method thereof, in particular to a water-based gold ink produced from common copper and gold powder and a preparation method thereof. Background technique [0002] For a long time, gravure gold ink has been made of acrylic resin to make solvent-based ink; since the solvent content in the ink exceeds 30-60%, a large amount of solvent volatilizes during the printing process, which is easy to cause environmental pollution and damage human health, and there are potential fire hazards. For environmental protection, we are all working hard. In the printing industry, many traditional toxic and highly polluting products have been banned. Water-based inks instead of solvent inks have become an inevitable trend in the development of inks. Water-based gold inks are environmentally friendly, non-toxic, non-polluting, and have no harmful gas emissions, which caters to today's direction of development. [0...
