Problems solved by technology

However, during the high-temperature firing process, a series of chemical reactions will occur in the color-forming metal compound, which usually leads to unstable or even incapable color development of metal oxides.
In response to this problem, China's patent application CN201510429407.0 (a color enhancer for inkjet bleed ceramic tiles and its use method) introduces ultrafine silica as a ceramic glaze powder additive as a color enhancer, but high temperature resistant granular silica The mixing interface between silicon and molecular-level chromogen is very obvious, which affects the uniformity of color development to a certain extent
There is no literature report about directly adding oil-soluble molecular-level color enhancers in oily ceramic bleed color inks

Embodiment 1

[0024] Example 1: Preparation of oily antimony-based chromogenic ink color enhancer raw materials

[0025] (1) The preparation of three (isooctyl thioglycolate) antimony: add 61.30g (0.3mol) isooctyl thioglycolate, 13.25g (0.045mol) antimony trioxide and 45g water in the round bottom flask, magnetic stirring, Reflux reaction at 80°C for 2 hours, after cooling, separate the liquid through a separatory funnel to remove the upper aqueous phase; the lower organic phase is distilled under reduced pressure by a circulating water vacuum pump to remove the water remaining in the oil phase to obtain an oily antimony-based color-developing ink color enhancer Raw materials - Tris (isooctyl thioglycolate) antimony YSb1, set aside. Then test its elemental analysis and infrared spectrum, get respectively figure 1 and figure 2 .

[0026] figure 1 It is the EDS elemental analysis diagram of tris(isooctyl thioglycolate)antimony, according to the EDS elemental analysis, the content of anti...

Embodiment 2

[0035] Embodiment 2 Preparation of Oily Titanium Series Chromogenic Ink Color Enhancer Raw Materials

[0036] (1) Add 284g (1mol) of tetraisopropyl titanate and 288g (2mol) of isooctanoic acid into a round bottom flask, stir at room temperature for 1 hour, reflux at 100°C for 2 hours, remove small molecules under reduced pressure after the reaction is completed, and cool , to obtain viscous liquid titanium isooctanoate isopropoxy compound ((C 3 h 7 O) m Ti(OOCC 7 h 15 ) n ), which is oily titanium series chromogenic ink color enhancer raw material YT1, for subsequent use.

[0037] (2) Add 340 g (1 mol) of tetrabutyl titanate and 432 g (3 mol) of isooctanoic acid into a round-bottomed flask, stir at room temperature for 1 hour, reflux at 140°C for 2 hours, remove small molecules under reduced pressure after the reaction is completed, and cool. Obtain viscous liquid titanium isooctanoate butoxylate ((C 4 h 9 O)m Ti(OOCC 7 h 15 ) n ), which is oily titanium series chro...

Embodiment 3

[0040] According to the ratio in Table 1, 93 parts by mass of YSb1 and 7 parts by mass of isooctanoic acid were uniformly mixed at room temperature to obtain 100 parts by mass of oily ceramic bleed color ink color enhancer, and its pH value was measured to be 5. Then take 5 parts by mass of it, mix it with 100 parts by mass of the yellow chromogenic ink at room temperature, filter through a filter hole of 0.3 μm, and print the filtrate and the pure yellow chromogenic ink on the ceramic body or glaze by digital inkjet respectively Above, after firing at a high temperature of 650°C for 4 hours, observe the ink color development effect before and after the color enhancement of the ceramic body or glaze after cooling. The experimental results are listed in the last column of Table 1.

Abstract

The invention belongs to the field of the digital printing material, and particularly relates to an oil-based ceramic pattern-bleeding coloring ink toner and a preparation method and using method thereof. The toner is formed by 50-95 wt% of a coloring metallic compound and 50-5 wt% of an organic solvent. The coloring metallic compound is at least one of an acid solvent, a hydrocarbon solvent and an ester solvent. According to the mass ratio of 4-50:100, the toner and the coloring ink are uniformly mixed under the room temperature, the filtrate obtained by filtering of filtration pores of which the diameter is less than 5 um is printed on a ceramic rough-body or a glaze through the digital ink-jet, sintering for 1-4 hours under 650-1250 DEG C of the high temperature, not only the coloring ink can show various patterns and colors stably, but also the coloring vividness can be increased.

Description

technical field [0001] The invention belongs to the field of digital printing materials, and in particular relates to a color enhancer for oily ceramic bleed color ink and its preparation and usage. Background technique [0002] The rapid development of digital technology has greatly improved the quality and popularization of printing technology. Ceramic digital inkjet printing technology is a ceramic surface decoration technology, which can be conveniently and quickly automatically printed into various patterns through computer design, making the patterns of ceramic tile products more abundant, realistic, personalized and full of unlimited creativity.
