Problems solved by technology

[0002] It has been nearly ten years since the technology of inkjet printing high-temperature ceramic images and the modification and application of printing equipment have come out. However, most of the inkjet printing technology of ceramic images circulating in the market is printed with uncoated "hot-baked printing ink with sugar". This kind of printing ink usually uses glucose as an adsorbent in order to absorb the porcelain powder pigment, so it is viscous and easy to crystallize. The ink must be used continuously. Once it is stopped, the printing nozzle will be blocked, and the printing process must be repeated. Four times of thermal baking treatment, and it is not suitable for the use of Epson inkjet printers; some also use coating, but they all use gelatin as the base, and the weather is humid and cannot be used, and thermal baking treatment is still required before and after printing; the self-proclaimed printing ink is not It will block the nozzle. After research, it is only used to soak the nozzle of the ink cartridge in sponge water for maintenance, and then take it out and put it in the trailer for printing when printing, which is inconvenient
After the printed porcelain image is sintered at high temperature, the color contrast is poor and the fullness is not enough, which restricts the development and market share of the inkjet printing high-temperature porcelain image industry

Embodiment 1

[0014] An organic coating primer for porcelain image printing, which is prepared from gum arabic, defoamer, formaldehyde and purified water. When preparing, first use a balance to measure 240g of gum arabic and add it to 750ml of water. After soaking and dissolving for several hours, the solution can be heated to promote further dissolution. After the gum arabic is dissolved in water, a viscous colloidal solution is formed, and then cooled to room temperature; Then measure 5g of defoamer and 5g of formaldehyde solution and add them to the solution, and use a mixer or other tools to stir, stir evenly, and seal and store for later use.

[0015] When using, first filter the primer solution prepared by the above method, and then apply the primer solution evenly on the porcelain plate by spraying or brushing, and wait for it to dry naturally or with a hair dryer. Form a coating.

[0016] When printing, relying on the coating can effectively stabilize the printing ink, and can prom...

Embodiment 2

[0018] An organic coating primer for porcelain image printing, which is prepared from peach gum, defoamer, formaldehyde and purified water. When preparing, first use a balance to measure 180g of peach gum and add it to 800ml of water. After soaking and dissolving for several hours, the solution can be heated to promote further dissolution, and then cooled to room temperature; then measure 10g of defoamer and 10g of formaldehyde solution and add to solution, and use a blender or other tools to stir, stir evenly, and seal it for storage for later use.

Embodiment 3

[0020] An organic coating primer for porcelain image printing, which is prepared from gum arabic, defoamer, formaldehyde and purified water. When preparing, first use a balance to take 300g of gum arabic and add it to 680ml of water, soak and dissolve for 5 hours, and heat the solution to promote further dissolution, and then cool to room temperature; then measure 5g of defoamer and 15g of formaldehyde solution and add to solution, and use a blender or other tools to stir, stir evenly, and seal it for storage for later use.

Abstract

The invention provides an organic coating primer for porcelain image printing, which belongs to the technical field of high-temperature porcelain image printing and is used for solving the problem of easiness in blocking a printing spray head caused by ink used in the conventional high-temperature porcelain image printing. The organic coating primer for porcelain image printing is prepared from the following components in percentage by weight: 10-30 percent of a resin adhesive, 0.5-5 percent of an antifoaming agent, 0.5-3 percent of a preservative and 62-89 percent of purified water. After a coating is formed by coating the organic coating primer for porcelain image printing on a porcelain plate, ink can be printed effectively and stably, effective adsorption of a ceramic pigment with printing ink can be facilitated, and a burned high-temperature porcelain image in fresh in color, plump and clear. Due to the adoption of the organic coating primer, the component of glucose in ink can be eliminated, 'sugar-containing thermally-burnt printing ink' is not required for adsorbing the ceramic pigment, the viscosity of 'sugar-free printing ink' can be lowered, and the printing spray head is prevented from being blocked for a long time.
