specific Embodiment approach 1

[0010] Embodiment 1: In this embodiment, an inkjet recording material is made of PVC as the substrate, 20-30% polyacrylic acid emulsion as the primer, 10-100nm inorganic nano-pigments, dispersant, acetic acid, deionized water and adhesive The ink-absorbing layer coating solution made of an aqueous solution of the ink-absorbing layer is prepared; the preparation process of the ink-absorbing layer coating solution is: adding a dispersant in deionized water, adjusting the pH value to 5-7 by acetic acid, adding 10-100nm Inorganic nano-pigments are dispersed with a disperser at a speed of 7000-8000r / min for 30-40 minutes to obtain an inorganic nano-pigment solution. The inorganic nano-pigment solution and the binder aqueous solution are mixed at a mass ratio of 2.5-3.5:1, and then the Treat with an agitator or ultrasonic oscillator for 20-30 minutes, let stand for defoaming for 30-60 minutes, and obtain an ink-absorbing layer coating solution, wherein the mass ratio of dispersant to...

specific Embodiment approach 2

[0012] Specific embodiment two: this embodiment differs from specific embodiment one in that: a kind of inkjet recording material is made of PVC as base material, 25% polyacrylic acid emulsion is used as primer, 50nm inorganic nano-pigment, dispersant, acetic acid, It is made of ink-absorbing layer coating solution made of deionized water and binder aqueous solution.

specific Embodiment approach 3

Abstract

The invention provides an ink-jet recording material and a preparation method thereof as well as a method for preparing an ink absorption layer coating liquid, and relates to an ink-jet material and a preparation method thereof as well as a method for preparing an ink absorption layer coating liquid, so that the problems of poor ink absorption effect, nonuniform color distribution of printed images, unclear printed images and higher preparation cost of the existing ink-jet recording material can be solved. The ink-jet recording material is prepared from the ink-jet layer coating liquid which is prepared from PVC (polyvinyl chloride) serving as a base material, a 20-30% polyacrylic acid emulsion serving as a primer, an inorganic nano-pigment with the thickness of 10-100nm, a dispersing agent, acetic acid, deionized water and an adhesive aqueous solution. The prepared ink-jet recording material prepared through PVC material corona treatment, PVC substrate glue coating, drying, ink absorption layer coating and drying has the advantages that that the printed image is clear, the ink droplet does not diffuse, and the color is distributed uniformly; and the ink-jet recording material has excellent performances of color definition, color saturation, glossiness and the like. The raw material cost and the manufacture cost are low, so the ink-jet recording material is advantageous to industrial production, popularization and application.

Description

technical field [0001] The invention relates to an ink-jet material, a preparation method thereof, and a preparation method of an ink-absorbing layer coating liquid. Background technique [0002] Inkjet printing is gradually occupying the color inkjet printing market due to its small size, simple and convenient operation, low printing noise, clear imaging, and easy to accept price, and its main consumables, color inkjet printing materials, are increasingly attracting users' attention. Pay attention to. Most of the existing inkjet recording materials are mainly coated with a special ink-absorbing coating on the substrate, but the inkjet recording materials prepared by the existing method and ink-absorbing coating can only guarantee the completion of the inkjet printing process. The most basic graphics and text output effect cannot quickly absorb and dry ink, prevent ink from spreading, and cannot guarantee the imaging effect of inkjet printing. The color clarity and color sa...
