preparation example 1-3

[0041] Weigh 15kgMMA, 0.8kgHD, 8kg isooctane, 0.3kgAIBN, 0.3kgDVB respectively, stir and mix to obtain the oil phase, weigh 0.5kgSDS and 80kg water, stir and mix SDS and water to obtain the water phase, and mix the oil phase Add it into the water phase, stir magnetically for 30 minutes to obtain a microemulsion, disperse at high speed and homogeneously emulsify for 5 minutes to obtain a microemulsion. The miniemulsion was reacted at 65°C under a nitrogen atmosphere at a constant temperature for 2 hours, 10kg of vinyltriethoxysilane was added, and polymerized for 8 hours, 10 hours, and 12 hours respectively to obtain PMMA hollow microspheres with particle sizes of 20, 40, and 60 μm.

[0042] Modifier preparation example

preparation example 4-9

[0044] PMMA hollow microspheres with a particle size of 20-60 μm, silicon dioxide and acrylic resin were weighed, stirred and mixed to prepare Modifiers 1-6. The specific quality is shown in Table 1.

Abstract

The invention relates to the technical field of electronic appliances, and particularly discloses matte UV ink and a preparation method thereof. The matte UV ink comprises the following substances in parts by weight: 60-80 parts of polyurethane resin, 0.2-1 part of extinction wax powder, 0.2-1 part of a wetting dispersant, 0.2-1 part of a leveling agent, 15-25 parts of a diluent, 2-10 parts of a filler and 1-2 parts of other auxiliaries, the polyurethane resin is polyurethane resin modified by a modifier, and the modifier comprises PMMA hollow microspheres; the preparation method comprises the following steps: S1, pre-dispersing; and S2, ink preparation. The matte UV ink disclosed by the invention can be used for printing marks on electronic and electrical appliances, and has the advantages of being stable in gloss, not easy to float, uniform in extinction, and smooth in flatness; in addition, the preparation method disclosed by the invention has the advantages of simplicity and convenience in operation and uniform dispersion.

Description

technical field [0001] The present application relates to the field of electronic appliances, in particular to a matte UV ink and a preparation method thereof. Background technique [0002] UV (ultraviolet curing) ink is a kind of ink that polymerizes the monomers in the ink into polymers by ultraviolet light under the irradiation of ultraviolet rays, so as to realize the ink film formation and dry ink. UV ink has good printability, suitable curing and drying rate, good adhesion, wear resistance, corrosion resistance, weather resistance and other excellent characteristics. Moreover, UV ink has almost no pollutant emission, and has better environmental friendliness. [0003] With the development of society, the types of UV inks are also developing with time. At present, foaming inks, ice flower inks, hammer inks, crack inks, crystal inks, varnishes, and wrinkle inks are more common on the market. Due to changes in user requirements, matte inks with low gloss have become the...
