Problems solved by technology

[0004] In order to increase the aesthetics and artistic effects of ceramic products, color-changing inks based on color-changing agents have appeared. Due to the defects in the selection of binders and preparation processes, the prepared thermochromic inks do not meet environmental protection requirements and the production cost is relatively high. High, poor adhesion and friction resistance

Embodiment 1

[0019] Embodiment 1. In the embodiment of the present invention, a ceramic water-based color-changing ink includes the following components by weight percentage: color-changing water emulsion 35-45, water-based ink 10-18, sodium cellulose solution 30-40, glycerin 7-12 , Defoamer 3-6, water-based penetrant 0.5-0.8.

[0020] A ceramic water-based color-changing ink also includes 1-2 parts by weight of binder.

[0021] A ceramic water-based color-changing ink also includes 2.5-8.5 parts by weight of preservative.

[0022] The water-based ink comprises 5-10 parts by weight of soybean oil, 45-55 parts by weight of rosin, 25-40 parts by weight of water-based resin oil, and 2-4 parts by weight of dimethylethylamine dissolved in a suitable amount of water.

[0023] The defoamer is preferably tributyl phosphate.

[0024] The sodium cellulose solution is preferably 1.5% by weight sodium carboxymethyl cellulose.

[0025] The preservative is preferably amic acid at a concentration of 1.5% by weight...

Embodiment 2

[0029] Example two, a ceramic water-based color-changing ink, including the following components by weight percentage: color-changing water emulsion 20-30, thermal decolorization reversible pigment 20-25, water-based ink, 20-30, sodium cellulose solution 30 -40, glycerin 7-12, defoamer 3-6, water-based penetrant 0.5-0.8, in this example, increase the content of water-based ink, reduce the amount of color-changing water emulsion, and use thermal decoloring reversible color pigments , So that the ink has both photochromic and thermochromic effects.

Abstract

The invention discloses ceramic water-based color change ink, which is prepared from the following ingredients in percentage by weight: 35 to 45 parts of discolored water emulsion, 10 to 18 parts of water-based ink, 30 to 40 parts of sodium cellulose solution, 7 to 12 parts of glycerol, 3 to 6 parts of antifoaming agents and 0.5 to 0.8 part of aqueous penetrants. The ceramic water-based color change ink uses organic substances of sodium cellulose, glycerol and the like, so that the ink has organic environment-friendly features and better conforms to the environment-friendly requirements.

Description

Technical field [0001] The invention relates to the technical field of ceramic products, in particular to a ceramic water-based color-changing ink and a preparation method thereof. Background technique [0002] Ceramic printing is to use different plates and processes to make different printing plates, use special ceramic pigments and different binders to roll into printing inks, directly print on ceramics, or print on special paper, and then transfer It is a process technology to turn ceramics into ceramic products after high-temperature baking. [0003] Existing ceramic printing inks are actually synthetic inks, and there are subject synthetic resins and two-component inks that form transfer decal inks and ceramic inks. It is mainly composed of colorants and solvents. The colorants are colored minerals. The solvents are mostly lead borosilicate glass bodies. The two are further processed into solid solution or suspension pigments. [0004] In order to increase the aesthetics and ...
