Example Embodiment

[0026] Example 1

[0027] (The examples are the description of the specific implementation of the present invention and the above effects. The components and the content of the components involved must be specific substances and specific contents, not a general concept and a range, and it is better to give each implementation The effect of the ink of the example (see 1-6 above), so all the following examples need to be adjusted.)

[0028] The present invention provides a thixotropic ink-modifying oil, which contains 15-20 mgKOH / g resin solution, 95%-110% of the resin solution mass of the solvent, 2%-6% of the resin solution mass of the thickener, and the resin solution A plasticizer with a mass of 70%-330% and a defoamer with a resin solution mass of 0.1%-3%; the thickener is glyceryl stearate; the plasticizer is dioctyl phthalate .

[0029] In this embodiment, taking 100g resin solution as an example, the specific experimental data are as follows:

Example Embodiment

[0032] Example 2

[0033] The difference from Example 1 is that the resin solution is an acrylic resin solution. In the acrylic resin solution, add a small amount of acrylic acid. Helps improve the adhesion, hardness and gloss of the coating.

Example Embodiment

[0034] Example 3

[0035] The difference from Examples 1 and 2 is that the solvent is a high-boiling solvent with dual properties of aromatic hydrocarbons and alicyclic hydrocarbons, SN (tetralin) is the main solvent, and esters and alcohols are auxiliary solvents. Experiments show that the combined solvent can improve the thixotropy of the varnish.

Abstract

The invention relates to thixotropic varnish and a preparation method thereof. The thixotropic varnish comprises 15-20mg KOH/g of a resin solution, 95-110 wt% of a solvent based on the resin solution, 2-6 wt% of stearin based on the resin solution, 70-330 wt% of dioctyl phthalate based on the resin solution and 0.1-3 wt% of a defoamer based on the resin solution. The thixotropic varnish provided by the invention has the benefits that the thixotropic varnish is good in thixotropic performance; the ceramic burned is free of carbon black trace and good in adhesive force; the pigment dispersibility is good.

Description

technical field [0001] The invention belongs to the technical field of inks, and in particular relates to a thixotropic varnish used for decal printing in ceramics, glass and enamel industries and a preparation method thereof. Background technique [0002] Varnishes are mainly used for decal printing in the ceramics, glass and enamel industries. From the perspective of rheology, such varnishes are divided into flow type and thixotropy type. The former is a Newtonian fluid and is mainly suitable for screen printing; the latter is a non-Newtonian fluid and is mainly suitable for dot printing. [0003] Varnish is an organic polymer. Ink varnish is added to the pigment, and the pigment is fully mixed and evenly mixed by the ink press machine to ensure the uniformity of the printed decal paper, and then a solvent is added to adjust the thinness of the pigment, which is convenient for printing the decal paper and improving the drying speed of the decal paper, ensuring Paper qua...
