preparation example Construction

[0037] The embodiment of the present invention also provides a preparation method of the ink of the present invention. figure 1 Be the process flow sheet of the preparation method embodiment of printing ink of the present invention, as figure 1 shown, including the following steps:

[0038] Step 1: Weigh the raw material components described in the above flux examples according to the above weight percentages and then fully mix them to make a mixture;

[0039] Step 2: Melt the mixture at a set temperature for a set time to form a molten mixture. The set temperature can range from 1000°C to 1600°C, and the set time can range from 0.1 to 3 hours ;

[0040] Step 3: cooling and solidifying the molten mixture, pulverizing and sorting to form a flux;

[0041] Step 4: Mix the toner into the flux and homogenize to form a powder;

[0042] Step 5: Mix the powder with varnish, stir, homogenize, grind, roll, and defoam to make ink.

[0043] The preparation method of the ink provided ...

Embodiment 1

[0045] Embodiment 1 of the present invention provides a method for preparing ink, based on the above method for preparing ink, and specifically:

[0046] Step 1 is specifically carried out with 61.6% by weight of bismuth oxide, 5.1% by weight of aluminum oxide, 9.5% by weight of boron oxide, 16.2% by weight of barium oxide, and 7.6% by weight of zinc oxide Mix well to make a mix.

[0047] Step 2 is specifically to melt the mixture in a platinum crucible in an electric furnace at 1200°C for 1 hour to form a molten mixture;

[0048] Step 3 is specifically to pour the molten mixed solution into deionized cold water, water quenching and rapid cooling to obtain a fluffy coral-like flux, and use alumina balls and deionized water to wet-grind the fluffy coral-like flux in an alumina ball mill to The average particle diameter becomes the fine powder of 0.9 micron (μm) (average particle diameter is measured with SALD2100 laser refraction particle size distribution instrument manufactu...

Embodiment 2

[0058] Embodiment 2 of the present invention provides a method for preparing ink, based on the above method for preparing ink, and specifically:

[0059] Step 1 is specifically to use 32.4% by weight of bismuth oxide, 8.8% by weight of aluminum oxide, 13.3% by weight of boron oxide, 7.6% by weight of barium oxide, 15.2% by weight of zinc oxide, The silicon oxide of 16.2% by weight and the sodium carbonate of 6.5% by weight are fully mixed to make a mixture;

Abstract

The invention relates to a fusing agent, ink and a preparation method thereof. The fusing agent is prepared by fusing, cooling and pulverizing raw material components. The raw material comprises the following components by weight percentage: 30 percent to 78 percent of bismuth oxide, 5 percent to 25 percent of aluminum oxide, 2 percent to 16 percent of boric oxide, 1 percent to 27 percent of barium oxide or calcium oxide and 1 percent to 20 percent of zinc oxide. The invention also provides the ink containing the fusing agent, and the ink also comprises 0 percent to 50 percent of toner and 4 percent to 80 percent of thickened oil by weight percentage. In the fusing agent, the ink and the preparation method thereof, the fusing point temperature and the swelling coefficient of the fusing agent can be matched and regulated according to the characteristics of needed products to reach better attaching effect; the ink has the advantages of good glossiness, bright color, high firmness, good water resistance, good fusing resistance, good abrasive resistance, and the like; and the preparation method and the preparation process of the ink are simple, thereby being suitable for industrialized production.

Description

technical field [0001] The invention relates to chemical technology, in particular to a flux used in a flux-based ink, an ink including the flux and a preparation method thereof. Background technique [0002] In the production process of glass, ceramics, metal and other products, various inks are usually used for marking, masking, strengthening and coloring. Ink is generally composed of flux and varnish in a certain proportion. When the ink needs to show a certain color, it is necessary to add colorant. In the prior art, a large number of scented inks, fluorescent inks, foaming inks, fast-curing inks, and ultraviolet (Ultra Violet; hereinafter referred to as: UV) curing inks are all dried and cured at room temperature, while infrared light (Infrared Ray ; Hereinafter referred to as: IR) Curing ink needs to be dried and cured at high temperature. Further, IR curable inks can be divided into organic-based inks and solvent-based inks. Among them, although the amino type and ...
