Embodiment 1

[0044]This embodiment provides an LED light-curable inkjet printing varnish, the formula of which is shown in Table 1.

[0045] Table 1

[0046]

[0047] According to the formulations of the components listed in Table 1, first the prepolymer resin GU3030Z, GU8100W and aldehyde and ketone resin CT-120 are added to the active diluent (monofunctional monomer isobornyl methacrylate and difunctional Monomer diethanol dimethacrylate), stirred at a high speed of 4000rad / min for 50min to completely dissolve the resin, then added initiator, leveling agent, polymerization inhibitor and ultraviolet absorber under the condition of avoiding light, to Stir at a speed of 3000rad / min for 60min to obtain low temperature resistant LED photocurable inkjet printing varnish. The varnish has a viscosity of 10.12cp at 40°C and a surface tension of 28.02mN / m. It has good printing fluency on the printer. It can be completely cured after being irradiated with LED light with an emission wavelength o...

Embodiment 2

[0049] This embodiment provides an LED light-curable inkjet printing varnish, the formula of which is shown in Table 2.

[0050] Table 2

[0051]

[0052] According to the formulations of the components listed in Table 2, first the prepolymer resin GU4075B, GU9900Y and aldehyde and ketone resin A81 are added to the reactive diluent (monofunctional monomer lauryl acrylate and difunctional monomer In neopentyl glycol diacrylate), stir at a high speed of 3800rad / min for 55min to make the resin dissolve completely, then add initiator, leveling agent, polymerization inhibitor and ultraviolet absorber under the condition of avoiding light min at a speed of stirring for 65 min to obtain low temperature resistant LED photocurable inkjet printing varnish. The varnish has a viscosity of 10.08cp at 40°C and a surface tension of 28.30mN / m. It has good printing fluency on the printer. It can be completely cured after being irradiated with LED light with an emission wavelength of 395nm ...

Abstract

The invention relates to low-temperature resistant light-cured inkjet printing gloss oil for an LED and a preparation and application of the gloss oil. The gloss oil comprises the ingredients in percentage by mass: 10.0%-30.0% of prepolymer resin, 2.0%-8.0% of aldehyde ketone resin, 30.0%-60.0% of reactive diluent, 5.0%-10.0% of photoinitiator, 0.5%-1.5% of leveling agent, 0.3%-1.5% of polymerization inhibitor and 0.5%-2.0% of ultraviolet absorbent. The preparation method comprises the steps: adding the aldehyde ketone resin and the prepolymer resin into the reactive diluent, carrying out stirring, then, adding the photoinitiator, the leveling agent, the polymerization inhibitor and the ultraviolet absorbent under light-tight conditions, and carrying out stirring. The gloss oil is good inlow-temperature resistance, flexibility and bending resistance after the gloss oil cures to form a film.

Description

technical field [0001] The invention belongs to the field of photocurable ink and its preparation and application, and in particular relates to a low-temperature resistant LED photocurable inkjet printing varnish and its preparation method and application. Background technique [0002] Varnish is a kind of transparent light-curable ink, which can be used on various printing substrates to improve the application properties of the substrate such as color fading, wear resistance, and gloss. Therefore, light-curable varnish has also been developed rapidly. The light curing of varnish can be divided into LED light source curing and high-pressure mercury lamp curing according to the different curing light sources. Compared with high-pressure mercury lamp curing, LED light source curing has incomparable advantages. The heat causes the substrate to shrink and deform due to overheating, so LED light curing technology can develop rapidly. At present, there are not many researches on ...
