Embodiment 1

[0018] Example 1: The composition of the UV ink material is: 60% pure acrylic resin (UB101 pure acrylic resin), 25% neopentyl glycol diacrylate, 7% aluminum isooctanoate, 8% photosensitizer (184), the above percentages are by mass percentage.

[0019] The preparation process of UV ink:

[0020] 1. Check all circuits, instruments, pumps, and reaction bottles, and prepare defoamers.

[0021] 2. Put the UV resin into the reactor and start stirring at 60 rpm.

[0022] 3. Make a slurry of aluminum isooctanoate and neopentyl glycol diacrylate, and slowly put it into the reaction kettle under stirring.

[0023] 4. Turn on the circuit and heat up to 70°C. After stopping the heating, the temperature will rise naturally (naturally rise to below 80°C) and keep warm at this temperature for 45 minutes (beware of overflowing the pot at this time).

[0024] 5. Add 184 photosensitizer after keeping warm here until it is qualified.

[0025] 6. Thermal insulation transparent glue (no partic...

Embodiment 2

[0033] The material composition of UV ink is: 55% pure acrylic resin (UB101 pure acrylic resin), 30% neopentyl glycol diacrylate, 8% aluminum isooctanoate, 7% photosensitizer (184), the above percentages are mass percentages.

[0034] The preparation process of UV ink:

[0035] 1. Check all circuits, instruments, pumps, and reaction bottles, and prepare defoamers.

[0036] 2. Put the UV resin into the reaction bottle and start stirring.

[0037] 3. Make a slurry of aluminum isooctanoate and neopentyl glycol diacrylate, and slowly put it into the reaction kettle under stirring.

[0038] 4. Turn on the circuit and heat up to 70°C (so that it will naturally heat up to 80°C) and keep it warm at this temperature for 60 minutes (beware of overflowing the pot at this time).

[0039] 5. Add 184 photosensitizer after keeping warm here until it is qualified.

[0040] 6. Thermal insulation transparent glue (no particles), can be stacked as qualified.

[0041] If foam occurs, defoamer...

Abstract

The invention discloses UV (Ultraviolet) ink, which consists of 55-60 percent by mass of UV resin, 25-30 percent by mass of dimethyltrimethylene glycol diacrylate, 7-8 percent by mass of aluminum isocaprylate and 7-8 percent by mass of a photosencitizer. The invention further discloses a method for manufacturing a local grating by using the UV ink. The method comprises the following steps of: printing twice on a printed product based on the alignment of grating lines in a screen printing way; and curing two printing results respectively through a UV photo-curing reaction to obtain the local grating. In the method, screen printing is combined with the UV ink for printing directly on the printed product, so that a process is simple, convenient and rapid.

Description

technical field [0001] The invention relates to a UV ink and a method for preparing a local grating by using the UV ink, belonging to the field of three-dimensional printing. Background technique [0002] Three-dimensional photo paper, three-dimensional printing and other inventions and creations involving grating technology have brought grating technology into people's sight more and more, but the shortcomings of the original grating are becoming more and more obvious. The most prominent is that it cannot manufacture partial gratings. , can not meet the needs of actual production, and often lead to more economic investment and waste of resources. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a UV ink and a method for preparing a partial grating using the UV ink. [0004] The present invention uses screen printing to print two layers of UV ink on the printed product to create an optical effect similar to a g...
