Water-based printing ink preparation method

Abstract

The invention relates to a water-based printing ink preparation method. A water-based printing ink preparation device is used. The water-based printing ink preparation device comprises a preparation box, a grinding mechanism, a screening mechanism, a scraping mechanism and a collecting box, the preparation box is of a rectangular structure, the grinding mechanism, the screening mechanism and the collecting box are sequentially arranged on the inner wall of the preparation box from top to bottom, and the scraping mechanism is arranged on the grinding mechanism. According to the method, the grinding mechanism can conduct double grinding on ink raw materials, so that the ground ink raw materials are finer, mixing and stirring of the ink raw materials are facilitated, the mixing stirring effect behind the ink raw materials is prevented from being influenced due to the fact that the grinding of the ink raw materials is not fine, meanwhile, the ink raw materials adhered to a first grinding roller and a second grinding roller on the grinding mechanism are scraped off by adopting the scraping mechanism, so that the adhered raw materials are prevented from influencing the grinding of a grinding roller, and therefore, the grinding effect of the grinding roller is not good.

Description

technical field [0001] The invention relates to the technical field of water-based printing ink preparation, in particular to a preparation method of water-based printing ink. Background technique [0002] Water-based printing ink Water-based ink is referred to as ink for short, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. It is an important material for printing. At the same time, it The pattern and text are displayed on the substrate by printing or inkjet painting. It is often used in various printings such as books, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of inks have also expanded and increased accordingly. When printing ink is processed and prepared, its raw materials need to be ground into powder for later mixing and stirring, but the follow...

Problems solved by technology

[0003] In the process of grinding and preparing water-based printing ink, more raw materials are often adhered to the grinding roller, which cannot be cleaned in time. The adhered raw materials will easily affect the grinding roller for grinding, resulting in the grinding effect of the grinding roller. poor;

[0004] When grinding water-based printing ink raw materials, single grinding is mostly us
