Embodiment 1

[0039] Prepare the ceramic continuous offset printing ink of the present embodiment as follows:

[0040] (1) Preparation of acidic aluminum sol: In a stirring reactor with reflux and continuous stirring, add water and raise the temperature to 85°C, add SB pseudoboehmite dry powder during stirring, control the temperature at 80°C and stir for 4h, add nitric acid to control the temperature at 80°C After reacting at ℃ for 8 hours, cool to room temperature, stop stirring, and age for 30 hours to obtain acidic silica sol; the ingredients are: water, SB pseudo-boehmite dry powder in a mass ratio of 100:6, SB pseudo-boehmite dry powder, nitric acid The amount ratio of substances is 100:10; the SB pseudoboehmite dry powder is PURAL SB, a product of German sasol company; the obtained acidic aluminum sol is translucent and milky white, and the light path can be seen clearly when irradiated by thin beams of light, pH3.9, average colloidal particle 9nm in diameter, stable and no detectabl...

Embodiment 2

[0046] Prepare the ceramic continuous offset printing ink of this example basically according to the method of Example 1, the difference is that when preparing the acidic aluminum sol in step (1), the ratio of the amount of SB pseudoboehmite dry powder to nitric acid is 100:8; the obtained acidic aluminum sol , translucent milky white, a clear light path can be seen when irradiated by thin beams of light, pH4.1, average colloidal particle diameter 10nm, stable and no detectable change in airtight storage at room temperature for 6 months; the aluminum sol-heat-cured phenolic resin composite solution B obtained in step (3) , translucent light brownish red, pH 8.0, a clear optical path can be seen when irradiated by thin beams of light, the average diameter of the detected colloidal particles is 10nm, and the viscosity is about 780mPa.s; it is stable and has no detectable changes after 3 months of sealed storage at room temperature.

Embodiment 3

[0048] Prepare the ceramic continuous offset printing ink of this embodiment basically according to the method of Example 1, the difference is that when preparing the heat-cured phenolic resin in step (2), the ingredients are based on the formaldehyde solution in terms of formaldehyde, phenol, and borax, and the ratio of the amount of substances is 2.0:1: 0.04; The obtained heat-cured phenolic resin is transparent light brownish red, with a viscosity of 1200mPa.s, stable and no detectable change in airtight storage at room temperature for 3 months; step (3) gained aluminum sol-thermally cured phenolic resin composite liquid C is translucent Light brown-red, pH8.1, a clear light path can be seen when irradiated by thin beams of light, the average diameter of the detected colloidal particles is 10nm, and the viscosity is about 730mPa.s; it is stable and has no detectable changes for 3 months in airtight storage at room temperature.

Abstract

The invention provides high-adaptability ceramic continuous offset printing ink, printing ink and application thereof. The stamp-pad ink comprises the following components: 100 parts of alumina sol-thermocuring phenolic resin composite liquid, 1.5-3 parts of sodium polyacrylate, 3-5 parts of guar gum, 8-12 parts of tripolyglycerol, 3-6 parts of Span 60 and 2-3 parts of castor oil. The printing ink is prepared by adding 60-120 parts of ceramic toner into 100 parts of stamp-pad ink, has balanced plate sticking, adhesive and ceramic sticking performance and plate and adhesive separating performance, and is high in offset printing speed, high in precision and good in adaptability to ceramic glaze performance, and the offset 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 glazes, and in particular relates to a highly adaptable ceramic continuous offset printing oil, ink and application thereof. Background technique [0002] Ceramic surface decoration, such as aesthetic patterns, patterns, and characters, is an important decorative identification element for most ceramic products; The ink layer is printed on or under the layer, and then fired. The thickness of the ink layer is generally significantly lower than that of the glaze layer; on-glaze decoration is the mainstream. [0003] Ceramic glaze decoration is to apply a small amount or thinner ink to the surface of a larger or thicker glaze layer. During the heating process from drying after ink printing to firing, there are problems with the self-strength of the ink layer and its adhesion to the glaze layer; during the high-temperature firing process, the thinner dry ink layer and the thicker glaze There are pro...
