Problems solved by technology

[0004] With the rapid development of my country's economy and the continuous improvement of the living standards of our people, digital photography equipment has become an indispensable tool for every family, followed by a huge increase in the demand for color inkjet printing materials , many domestic manufacturers spare no effort to invest financial and material resources in the development and production of various color inkjet printing materials, but due to the influence of technology and raw materials, most of the current inkjet printing materials are made of polymers and silica or alumina and other materials. Inkjet printing materials in the form of additive compounding have not studied the physical and chemical processes of ink-absorbing media from the aspect of particle surface chemistry, so the inkjet materials produced can still meet the routine use, but the requirements for high precision and high definition Photo-grade inkjet printing materials are slightly inferior

Abstract

The invention discloses an ink absorption medium for color inkjet printing paper and a preparation method thereof. The ink absorption medium is characterized by consisting of components A and B in the weight ratio of 1:1-1.1, wherein the component A is a surface grafting coating of cationic polymer and nano silicon dioxide; and the component B is a surface grafting coating of the cationic polymerand nano aluminum oxide. In the method, surface physical and chemical properties of particles are modified; after the ink absorption medium is added into a surface coating of color inkjet paper, the color inkjet printing paper is prepared; after ink reaches the surface of paper, water of the ink is quickly absorbed and is filtered into the coating; and an adsorbent in the coating can quickly absorb the water so as to ensure that a dye is not scattered and color contamination is avoided, an ink drop is smooth, edges are clear, and the finally formed image is vivid, has high resolution ratio, bright color and high ink absorption and color saturation, is quickly dried and is rich in gradation.

Description

technical field [0001] The invention relates to an ink absorption medium for color inkjet printing paper. Background technique [0002] The adsorption medium is the adsorption material in the surface coating of color inkjet paper. The coating is the receiving object of the color ink, so the characteristics of the medium are the characteristics of the coating. After the ink reaches the surface of the paper, the moisture in it is quickly absorbed and penetrates into the coating Inside, the adsorption medium in the coating affects the printing quality such as the water absorption speed, whether diffusion occurs, and whether there is no cross-color. [0003] With the rapid development of integrated circuits, information technology and digital technology, color inkjet printing materials have rapidly entered thousands of households, and are growing at a very high growth rate every year. The ever-expanding market capacity and high-tech added value The high profit margins will inev...
