Problems solved by technology

[0004] Although the coating formed after some oil-based coatings can meet the requirements of high brightness and subsequent rapid bronzing processing, more harmful substances will be volatilized during use, causing great environmental pollution and failing to meet environmental protection requirements (especially in the cigarette pack industry. volatile organic compound limit requirements), and the cost is higher
[0005] Although water-based coatings have little environmental pollution, the coatings formed by the water-based coatings currently on the market cannot meet the requirements of high brightness and subsequent rapid bronzing processing at the same time.
Although the coating formed by some water-based coatings has high brightness, it is not suitable for bronzing processing or the bronzing efficiency is low, and the bronzing pattern is incomplete; although the coating formed by some water-based coatings is suitable for subsequent rapid bronzing processing, the gloss very low brightness

Abstract

The invention relates to a water-based coating. The water-based coating is prepared form the following raw materials in percentage by weight: 52 to 55 percent of water, 0.5 to 0.7 percent of sodium dodecyl sulfate, 20 to 25 percent of methyl methacrylate, 3 to 4.5 percent of butyl acrylate, 0 to 2 percent of ethyl hexyl acrylate, 1 to 1.5 percent of acrylic acid, 10 to 15 percent of butyl methacrylate, 1 to 2 percent of butyl maleate, 0.6 to 1 percent of ethyl acrylate, 0.4 to 1 percent of itaconic acid, 0.8 to 1 percent of ammonia water, 0.1 to 0.2 percent of antifoaming agent, 0.05 to 0.1 percent of sodium acetate, 0.1 to 0.2 percent of preservative and 0.1 to 0.2 percent of potassium persulfate. The invention also provides a method for preparing the water-based coating. The water-based coating of the invention is innoxious and has a small amount of environmental pollution; and a coating layer formed by coating has the advantages of high brightness, toughness, excellent anti-explosion performance, excellent subsequent processing performance, capability of stamping gold rapidly and efficiently and good gold stamping effect.

Description

technical field [0001] The invention relates to a paint composition, in particular to a water-based paint and a preparation method thereof. Background technique [0002] In the packaging and printing industry, after coating a layer of paint on the white cardboard, it can form a high-gloss paper with high brightness. As people's requirements for the decorative effect of packaging materials are increasing day by day, high-gloss paper is required not only to have high brightness, but also to be suitable for subsequent fast and efficient bronzing processing. Moreover, as people pay more and more attention to environmental protection, it is also required that the coatings emit less or no harmful substances during use, which meets the requirements of environmental protection. [0003] At present, the coatings used in the packaging and printing industry include oil-based coatings and water-based coatings. [0004] Although the coating formed after some oil-based coatings can meet...
