Problems solved by technology

The above-mentioned high-temperature glass ink and low-temperature glass ink need to bake (or sinter) the glass ink coating during use, which requires high energy consumption; at the same time, during the baking (or sintering) process, due to the high temperature , the controllability of the curing process is poor, and it is difficult to adjust the conditions and parameters of the ink curing in time according to the curing situation of the glass ink. Yield rate of ink products
[0003] Aiming at the problem that glass ink needs to be cured at high temperature, researchers have developed a glass ink that can be cured by self-drying or light. Self-drying curing does not require high energy consumption, so that the ink coating can be dried under natural conditions,

Example Embodiment

[0041] Example 1

[0042] 1. Preparation of filler:

[0043] Add talc, calcium carbonate, atactic polypropylene, and titanium dioxide into the ceramic ball mill. After ball milling for 25 minutes, add the ball milled mixture to the reaction kettle containing terpineol. Control the stirring speed to 160r / min. After stirring for 12 minutes, Adjust the stirring speed to 550r / min, add sodium hexyl xanthate dropwise, continue stirring for 30 min, to prepare the filler; the talc, calcium carbonate, atactic polypropylene, titanium dioxide, sodium hexyl xanthate The mass ratio of terpineol is 1:0.8:0.06:0.03:0.01:0.6.

[0044] 2. Preparation of six-functional polyurethane acrylate:

[0045] Mix isophorone diisocyanate and polyethylene glycol 400 into a microwave radiation reactor equipped with a stirring device, control the stirring speed to 450r / min, react at 95°C for 32 minutes and add 2,2-dimethylol Propionic acid and zinc stearate, continue to react, measure the free isocyanate content ...

Abstract

The invention discloses a UV-LED glass ink and a preparation method thereof. The glass ink is prepared by the steps: taking polyester acrylate, difunctional polyurethane acrylate and hexafunctional polyurethane acrylate as main raw materials, adding an active monomer, a filling agent, a photoinitiator, an auxiliary agent and silicon dioxide, and evenly mixing the raw materials and grinding to prepare the glass ink. The glass ink has the characteristics of fast curing speed and high curing efficiency. By adjustment of the composition of the filling agent, the glass ink with different appearanceeffects can be prepared. The invention also provides a use method for the UV-LED glass ink; 250-300 mesh screen printing is adopted, the thickness of an ink layer is controlled to 10-30 [mu]m, and photo-curing is carried out for 40-60 s after printing is completed. The glass ink has short curing time and good curing effect, cannot make glass products yellowed, and does not cause damage to operator bodies due to too strong light illumination in the curing process.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a UV-LED glass ink, a preparation method and a use method thereof. Background technique [0002] Glass ink refers to the ink that can be printed on glass and can adhere firmly. In the process of using glass ink, the glass ink coating is formed after coating the glass ink on the surface of the glass substrate. In order to make the glass ink work normally, the glass ink coating needs to be cured. The conventional treatment method is High-temperature curing method: For high-temperature tempered glass ink, the glass ink coating needs to be cured at a sintering temperature of 720-850°C; after curing, the ink and glass are firmly fused together, and are widely used in architectural glass, automotive glass and home appliance glass and other fields. For low-temperature glass ink, it is necessary to bake the glass ink coating at 100-180° C. to cure the glass ink coating and exhi...
