Abstract

The invention discloses a particle size control agent for inclusion red and yellow ink, as well as a preparation method and an application method of the particle size control agent. The particle sizecontrol agent is prepared from raw materials in percentage by weight as follows: 3%-6% of 2-acrylamide-2-methylpropanesulfonic acid, 61%-80% of methyl methacrylate, 15%-31% of butyl acrylate and 2%-5%of azobisisobutyronitrile. The particle size control agent used for inclusion ink of cadmium selenide wrapped with zirconium silicate is convenient to use and good in storage stability; primary particle size of an inclusion ink precursor synthesized from the particle control agent is 100 nm or smaller, primary particles cannot be damaged by subsequent grinding treatment, the dispersed average particle size of the inclusion ink is 100 nm, and the defect that inclusion red and yellow pigment in the current market is ground too finely and has reduced color development power is solved.

Description

technical field [0001] The invention relates to the technical field of ink additives, in particular to a particle size control agent for wrapping red and yellow inks, a preparation method and an application method thereof. Background technique [0002] ZrSiO4 has a high melting point (2500°C), a high refractive index (1.93-2.01), and has the characteristics of resisting high-temperature glaze melts, so it has become the preferred wrapping phase for wrapping scarlet and wrapping yellow, which has attracted widespread attention from scholars at home and abroad, and Developed a batch of products wrapped with red and yellow ceramic printing inks. [0003] Although there is a synthesis method of zirconium silicate-coated red-yellow material in the existing technology, the average particle size of the synthesized red-yellow material is above 0.6um. Precipitation occurs and cannot be used to make stable ceramic inks. In order to meet the requirements for the use of inkjet printin...
