preparation example Construction

[0033] This embodiment also provides a preparation method of photocurable adhesive tape, comprising the following steps:

[0034] a. Weigh 100 parts of UV acrylic resin, 0.5-2 parts of initiator, and 0.2-0.5 parts of vitamins, place them in a vacuum mixer, stir for 3-5 minutes, and prepare mixed glue after fully stirring and mixing;

[0035] b. Using the roller-type hand coating method, pour the mixed glue between the substrate and the release film, adjust the distance between the substrate and the release film to 25-50 μm, and pull one end at a uniform speed to obtain an uncured adhesive tape;

[0036] c. Put the uncured tape into a UV curing device and adjust the energy to 2000-2300mJ / cm 2 , the curing time is 0.5-1min, and then taken out to obtain a photocurable adhesive tape.

[0037] Wherein, the speed of uniform pulling in step b is 6-10 m / min.

[0038] Specifically, several groups of implementation methods of preparation methods are provided below,

Embodiment 1

[0040] Weigh 0.2 parts of 7-dehydrocholesterol, 100 parts of UV acrylic resin, and 0.5 parts of 1-hydroxycyclohexyl phenyl ketone, place them in a vacuum mixer, stir for 3 minutes, and mix thoroughly to prepare a mixed glue. Using the roller-type hand coating method, pour the above mixed glue between the PVC substrate and the 25μm PET release film, adjust the distance between the substrate and the release film to 50μm, and pull one end at a uniform speed to obtain an uncured nail tape . Put the uncured nail tape into the ultraviolet curing device, adjust the energy to 2000mJ / cm2, and obtain the nail tape after curing for 0.5min.

Embodiment 2

[0042] Weigh 0.3 part of ergocalciferol, 100 parts of UV acrylic resin, and 1 part of 2-hydroxy-2-methyl-1-phenyl-1-acetone and place it in a vacuum mixer, stir for 4 minutes, fully stir and mix evenly, and prepare Gotta mix the glue. Using the roller-type hand coating method, pour the above mixed glue between the PVC substrate and the 25μm PET release film, adjust the distance between the substrate and the release film to 25μm, and pull one end at a uniform speed to obtain an uncured nail tape . Put the uncured nail tape into the ultraviolet curing device, adjust the energy to 2200mJ / cm2, and obtain the nail tape after curing for 0.8min.

Abstract

The invention discloses a light-cured adhesive tape and a preparation method thereof. The light-cured adhesive tape comprises a base material, a release film and an adhesive layer applied between thebase material and the release film, and the adhesive layer comprises 0.2-0.5 parts of vitamin, 100 parts of UV acrylic resin and 0.5-2 parts of an initiator. Compared with traditional thermocuring, more environment-friendly and safer ultraviolet curing is adopted, and the cured adhesive tape can generate vitamin D, so that the adhesive tape not only has a sticking effect, but also is beneficial toabsorption of vitamin D by nails and skin, and plays a role in medical care.

Description

technical field [0001] The present invention relates to a kind of photocurable adhesive tape, relate in particular to a kind of photocurable adhesive tape and its preparation process and application. Background technique [0002] The sports tape currently used on the human body or the nail stickers commonly used by women, etc., do not have any benefits to the human body during use, and are sometimes just for aesthetics. However, if vitamin D is added to these tapes, the existing effect can be achieved during use, and it can also help the body absorb vitamin D, promote the growth of nails and bones, and regulate immune function. [0003] Vitamin D (referred to as VD) is a fat-soluble vitamin, which is a cyclopentane polyhydrophenanthrene compound, a group of vitamins that are related to sterols in structure and can prevent rickets in function, the most important ones are vitamins D3 and D2. The former is formed by ultraviolet irradiation of 7-dehydrocholesterol under the hum...
