Embodiment 1

[0013] Get 54.27 light curing resin epoxy acrylic composite resin, 9.56 monomer diluent TPGDA; unit of weight.

[0014] First mix the above-mentioned TPGDA and TMPTA and stir evenly, then slowly add the above-mentioned photocurable resin epoxy acrylic composite resin, after fully dissolving, add the above-mentioned photosensitizer 1173, photosensitizer 184 and film-forming aids, and stir The material can be filtered evenly, and the main technical indicators of the UV varnish prepared in this way are as follows:

[0015] project

[0016] Viscosity (25℃cp)

[0017] After the UV varnish is prepared, it is pre-printed on the film to become a UV pre-printed decorative film. The decorative film is a transparent high-gloss film with a very high gloss. When in use, it only needs to be coated with water-based film-coating glue on the packaging paper, and the package can be given a high-grade UV protective layer by ordinary film-coating methods.

Embodiment 2

[0019] The photocuring resin epoxy acrylic composite resin of 52.17 is, the monomer diluent TPGDA of 9.56, the monomer diluent TMPTA of 9.56, the photosensitizer 1173 of 2.74, the film-forming aid of the photosensitizer 184 of 2.74, 18.13 are and 5.1 Pearlescent toner, the above is the weight unit.

[0020] First mix the above-mentioned TPGDA and TMPTA and stir evenly, then slowly add the above-mentioned photocurable resin epoxy acrylic composite resin, and after fully dissolving, add the above-mentioned photosensitizer 1173, photosensitizer 184 and film-forming aids, Stir evenly to filter out the material to obtain UV varnish. Then pre-wet the pearlescent toner with a diluent (ethanol) with 30% of the weight of the pearlescent toner pigment, then add the wetted pearlescent toner to the prepared UV varnish in batches, and stir gently while adding , so that the pearlescent pigment and UV varnish achieve the best mixing state. The main technical indicators of the UV varnish pr...

Embodiment 3

[0024] Prepare the UV varnish according to Example 1, then photoetch the pattern on the film, and pre-print the prepared UV varnish on the film with the photoetching pattern to become a UV pre-printed decorative film. After transferring the UV pre-printed decorative film to the paper, it can provide a better visual effect for the packaging, making the appearance more lively, and the reproduced hologram is dazzling, shining, and has a good dynamic effect. UV pre-printed decorative film has the advantages of safety, no harmful volatiles, no pollution to the environment, fast processing speed, high output, and strong versatility. The application of cosmetic packaging materials makes it more competitive in the packaging field.

Abstract

The invention discloses a UV gloss oil and a preparation method thereof and the use thereof; a monomer diluent TPGDA with the weight percentage of 8 to 12 percent and a monomer diluent TMPTA with the weight percentage of 8 to 12 percent are mixed to be stirred evenly, then a light-cured resin epoxy acrylic acid composite resin with the weight percentage of 50 to 55 percent is added in, after the mixture is dissolved fully, a photosensitizer 1173 with the weight percentage of 2 to 4 percent, the photosensitizer 184 with the weight percentage of 2 to 4 percent, a film-forming additive with the weight percentage of 10 to 20 percent and color powder with the percentage of 0 to 10 percent are added in, and after being stirred evenly, the UV gloss oil can be obtained by filtering. The prepared UV bright oil is used for being printed on films or films with lithography patterns to prepare UV preprinting decoration films which are used for product packing materials.

Description

technical field [0001] The invention relates to a UV varnish and its preparation method and application, in particular to a UV varnish which can be preprinted on a film. Background technique [0002] With the development of the market economy, high-end decorative printing is becoming more and more popular because it plays a good role in beautifying and promoting products. In recent years, due to its environmental protection advantages, UV curing has received strong support from relevant environmental regulations and close attention from the industry. While the market demand for UV radiation curing materials is growing rapidly, UV radiation curing systems are being combined with various technologies , to overcome some defects and meet the practical application. Now in the printing industry, UV enables packaging to achieve some special effects: high gloss, good ink protection characteristics, controllable slip and rub resistance, low or no odor, low extractables or undetectab...
