Embodiment 1

[0035] Prepare sodium polyacrylate-aluminum sol composite solution A as follows: In a stirred reactor, add sodium polyacrylate to room temperature water, beat until it becomes a glue, add aluminum isopropoxide and stir for 4 days to form a transparent light milky white glue , heated up to 80-85° C. and distilled under reduced pressure for 1 h until no isopropanol was left and the concentration of aluminum-containing sol was 12 m% based on alumina, and cooled to room temperature to obtain sodium polyacrylate-aluminum sol composite solution A. The mass ratio of ingredients is water, sodium polyacrylate, aluminum isopropoxide=120:1.3:30. The sodium polyacrylate used is XM-500 from Zhejiang Chunan Xumei Biotechnology Co., Ltd., with a degree of polymerization of 1200-1300. The purity of aluminum isopropoxide is over 99.9%.

[0036] The obtained sodium polyacrylate-aluminum sol composite solution A is transparent and light milky white, pH 8.1, and a clear optical path can be seen ...

Embodiment 2

[0038] Prepare sodium polyacrylate-aluminum sol composite liquid B basically according to the method of Example 1: In the same stirred reactor, add sodium polyacrylate to room temperature water, beat until it becomes a glue, add aluminum isopropoxide and stir for 5 days to form a transparent Warm up to 80-85°C and distill under reduced pressure for 1 hour until there is no residual isopropanol and the concentration of aluminum-containing sol is 15m% based on alumina, then cool to room temperature to obtain sodium polyacrylate-aluminum sol composite solution B. The mass ratio of ingredients is formulated according to water, sodium polyacrylate, aluminum isopropoxide = 120:2:50.

[0039] The obtained sodium polyacrylate-aluminum sol composite solution B is transparent and light milky white, pH 8.3, and a clear optical path can be seen when irradiated with thin beams of light, and the average particle diameter of aluminum sol is 8nm; it is stable and has no detectable change after...

Embodiment 3

[0045] Prepare thermosetting phenolic resin C as follows: In a stirred reactor, 37m% formaldehyde commercial aqueous solution is calculated as formaldehyde, phenol, and borax decahydrate are calculated as anhydrous matter, and the amount ratio of substances is 1.6:1:0.015. Formaldehyde solution, phenol ingredients, beating, heating up to 70°C and stirring for 15 minutes, adding a saturated aqueous solution of borax dropwise, raising the temperature to 85-90°C and maintaining this temperature for 3 hours, and then reacting under reduced pressure at 85-90°C for 1.5 hours to Sampling was carried out to detect that there was no formaldehyde, no phenol residue and about 35m% water, and cooled to room temperature to obtain heat-curable phenolic resin C.

[0046] The obtained heat-cured phenolic resin C is transparent and light brown-red; it is stable and has no visible change after being stored in airtight and light-shielding at room temperature for 3 months.

Abstract

The invention provides efficient and accurate daily porcelain 3D soft silica gel transfer printing ink and application thereof. The printing ink is prepared from 100 parts of stamp-pad ink and 60-120 parts of ceramic toner, the stamp-pad ink is prepared from the following components: 80 to 120 parts of sodium polyacrylate-aluminum sol composite liquid, 10 to 15 parts of thermocuring phenolic resin, 3 to 5 parts of guar gum, 5 to 10 parts of tripolyglycerol, 3 to 6 parts of Span 60 and 1.5 to 3 parts of castor oil. The printing ink has balanced plate-sticking, glue-sticking and ceramic-sticking performance and plate-separating and glue-separating performance, the transfer printing speed is high, the precision is high, the adaptability to the performance of domestic porcelain glaze is good, and the transfer printing effect is basically not affected by environment temperature and humidity fluctuation; and the printed and fired ornamentation is accurate in color, fine in line and clear in edge.

Description

technical field [0001] The invention belongs to the technical field of ceramic ink materials, and specifically relates to a high-efficiency and precise 3D soft silicone transfer printing ink for daily-use porcelain and its application. Background technique [0002] Daily-use porcelain generally includes meal, tea, kitchen and other related porcelain, such as bowls, plates, spoons, cups, pots and other small daily utensils, most of which have three-dimensional surfaces. Surface decoration, such as aesthetic patterns, patterns, and characters, is an important component of most daily-use porcelain; the refinement of surface decoration is the main goal of medium-to-high-end daily-use porcelain. [0003] In the production process of daily-use porcelain, on-glaze printing is the first step to form surface decoration. The fineness and precision of printing are the prerequisites for forming high-quality surface decoration; on the premise of achieving fine and precise printing effect...
