Problems solved by technology

[0004] However, since the LED-UV curing method can only emit energy of a single wavelength, inks that can be cured at a single wavelength must be used for printing
Traditional UV screen printing snowflake inks are difficult to dry under LED-UV light sources, and there is no way to produce normal patterns. At present, there are relatively few varieties of LED-UV inks, and the market is in the development stage
Currently, the patents disclosed for LED-UV inks include CN102732094 B, CN 103045007 B, CN 105567002 A, CN 104910679 A, ​​CN 103613989 A, CN102863848 A, and the curing speed, curing efficiency, adhesion and solvent resistance of LED-UV inks , weather resistance, etc. have been studied, and it does not involve LED-UV inks with special effects of snowflakes

preparation example Construction

[0031] A method for preparing LED-UV ink with snowflake special effects, comprising the steps of:

[0032] a: Weigh the following components by weight percentage: 27-52 parts of UV curable resin, 30-50 parts of reactive diluent, 10-16 parts of photoinitiator, 0-10 parts of pigment, 3-8 parts of filler, auxiliary agent 1 to 2 servings.

[0033] b: Put the raw materials such as ultraviolet curing resin, photoinitiator, reactive diluent, filler, auxiliary agent into the airtight container according to the proportion, and stir in the mixer with the rotation speed of 400-600rpm in the temperature range of 40-50°C for 20-20~ 30min, the raw materials are mixed and pre-dispersed, and stirred evenly;

[0034]c: use a three-roll mill to grind the dispersed raw materials in step a to 10-15um, and obtain LED-UV ink with special snow effect.

Embodiment 1

[0037] Take the following components respectively by weight proportion (parts):

[0038]

[0039]

[0040] Put the UV curable resin, photoinitiator, reactive diluent, filler, additive and other raw materials into the airtight container according to the proportion, and stir in the mixer with the speed of 400-600rpm in the temperature range of 40-50°C for 20-30min. The raw materials are mixed and pre-dispersed, stirred evenly, and finally ground to a fineness of 10-15um, and the LED-UV ink with the special effect of snowflakes is obtained.

Embodiment 2

[0042] Take the following components respectively by weight proportion (parts):

[0043]

[0044]

[0045] Put the UV curable resin, photoinitiator, reactive diluent, filler, additive and other raw materials into the airtight container according to the proportion, and stir in the mixer with the speed of 400-600rpm in the temperature range of 40-50°C for 20-30min. The raw materials are mixed and pre-dispersed, stirred evenly, and finally ground to a fineness of 10-15um, and the LED-UV ink with the special effect of snowflakes is obtained.

Abstract

The invention discloses an LED (light-emitting diode)-UV (ultraviolet) ink with special snow effects and a preparation method of the ink. The ink comprises, by weight, 27-52 parts of ultraviolet curable resin, 30-50 parts of activated diluents, 10-16 parts of photo-initiators, 0-10 parts of pigments, 3-8 parts of fillers and 1-2 parts of auxiliaries. The ink is cured and dried by an LED-UV light source, the wave band of the LED-UV light source can be 365nm, 375nm or 395nm, and curing power is higher than or equal to 8W / cm<2>. Compared with common UV ink, the ink has the advantages of high drying speed, good adhesive force, energy conservation, environmental protection and the like.

Description

technical field [0001] The invention relates to an ink, in particular to an LED-UV ink with a special effect of snowflakes and a preparation method thereof. Background technique [0002] UV silk screen snowflake printing is a special process for surface treatment of printed matter, which can produce transparent three-dimensional patterns on the color printing pattern of printed matter, making the printed pattern show novel and high-end decoration effect. UV curable screen printing snowflake ink first prints the ink on the pattern surface of the printed matter through the printing machine, and then detonates and solidifies to present the crystal clear texture texture like winter snowflakes. It is a special process ink of crystallization and fission type. [0003] Traditional UV screen printing snowflake ink uses ultraviolet rays as a curing light source to quickly cross-link and form a film at room temperature. The commonly used UV light sources are mainly high-pressure mercu...
