Problems solved by technology

However, the bonding method requires high quality equipment and workers, and the operation process of this method is complicated and time-consuming.
The method of exposure and development is currently in the trial stage of small batches. Its process flow is cumbersome, the yield rate is not high, and it requires high temperature baking, which consumes a lot of energy. At the same time, it uses a large amount of solvents to pollute the environment.

[0051] Preparation of hydrocarbon-terminated carboxyl silicone oil:

[0052] In parts by weight, add 65 parts of double-ended hydrogen silicone oil, 35 parts of β-carboxyethyl acrylate, and 0.05 parts of Karstedt catalyst into the reaction vessel, heat it to 60-145°C, and monitor it with an infrared spectrometer until Si-H The main bond disappears, the whole reaction time is 6-8 hours, and the hydrocarbon-terminated carboxyl silicone oil is obtained from the discharge.

[0053] Preparation of main body UV resin:

[0054] According to the formula shown in Table 1, add hydrocarbon-terminated carboxyl silicone oil, 3,4-epoxycyclohexyl methacrylate, polymerization inhibitor, and catalyst into the reaction vessel, heat to 85-135°C, and control the reaction temperature at 85- 135°C, keep warm until the acid value is less than 3mgKOH / g, the whole reaction time is 3-8 hours, and the main UV resin is obtained by discharging;

Abstract

The invention discloses ultraviolet curing UV ink jet ink as well as a preparation method and application thereof. The ultraviolet curing UV ink jet ink is prepared from the following components in parts by weight: 15-40 parts of matrix UV resin, 5-10 parts of triglycidyl isocyanurate, 10-15 parts of 3,4-epoxy cyclohexyl methacrylate, 10-15 parts of N-vinyl caprolactam, 5-10 parts of dipentaerythritol hexaacrylate, 5-10 parts of a photoinitiator, 1-5 parts of a silane coupling agent and 10-15 parts of pigments. The UV ink jet ink prepared according to the invention has excellent high temperature resistance and weather resistance as well as good adhesive force and hardness, is extremely low in viscosity, can be used for processing 3D bent glass of electronic equipment such as mobile phonesand tablet personal computers in an ink-jet printing manner, and is simple in processing technology, high in efficiency, low in energy consumption and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of UV ink-jet inks, in particular to an ultraviolet-cured UV ink-jet ink and a preparation method and application thereof. Background technique [0002] At present, the shading ink used for the screen cover glass is mainly a two-component epoxy ink, which is used to process the flat screen glass by silk screen printing. But its main disadvantages are: 1. It needs to be baked at high temperature, and the baking time is long; 2. It uses a large amount of organic solvents, which causes great pollution to the environment and is not conducive to environmental protection; 3. It can only be used on flat glass. Cannot be applied on curved glass. [0003] 3D curved glass is more and more widely used in the screens of electronic devices such as mobile phones and tablet computers. White ink or black ink is required around the 3D curved cover glass, mainly for shading. However, due to the above-mentioned defects of c...
