Problems solved by technology

Because the color material needs to pass through the pattern of the screen, if the paste used to prepare the color material has poor fluidity and poor mesh penetration, the scraped product color material is prone to defects, the thickness cannot be controlled, and problems such as poor outline definition will occur.

Abstract

The invention discloses a paste for ceramic screen printing and a preparation method thereof. The paste comprises the following components in percentage by mass: 20-60% of ammonium alginate, 20-60% ofhydroxyethyl cellulose, 10-20% of maltodextrin and 1-3% of a phosphorus-free complexing dispersant PAA. The printing paste is prepared by compounding ammonium alginate, hydroxyethyl cellulose, maltodextrin and a phosphorus-free complexing dispersant PAA, the components cooperate with each other, so that obtained printing paste simultaneously has a low ash content, high fluidity and good screen permeability, the market requirements of the paste for ceramic screen printing are met, the outline of printed patterns is clear, ceramic coloring is bright, and the paste is particularly suitable for ceramic screen printing. The preparation method of the paste for ceramic screen printing is simple and convenient to operate, and industrialization is easy to realize.

Description

technical field [0001] The invention relates to the technical field of printing paste, in particular to a paste for ceramic screen printing and a preparation method thereof. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. China is one of the first countries in the world to use pottery, and Chinese porcelain is highly respected by the world because of its high practicality and artistry. The ceramic industry is a traditional industry in China. With the development of the economy and the improvement of people's living standards, people's demand for porcelain is increasing. The efficiency of traditional hand-drawn patterns is low, and the sketching technology requires technical talents with artistic skills, which has high requirements for the on-the-job personnel, which is not conducive to large-scale production. [0003] With the continuous development of printing technology, the pattern of ceramics...
