Embodiment 1

[0018] 1. Preparation of active oligomers:

[0019] Add 150g of toluene to a 1000ml four-neck flask equipped with a stirrer, condenser, thermometer and dropping funnel, raise the temperature to 85±2°C, mix the monomers of each resin in advance, add 1.3g of azobisisobutyl Nitrile and 2.8g of dodecyl mercaptan are completely dissolved to make a monomer mixture, add 1 / 6 of the monomer mixture to the four-neck flask, stir, keep warm for 1 hour, add the remaining monomer dropwise, and finish dropping in 2.5-3 hours , keep warm for 2 hours, heat up to 110°C, add dropwise 2.3g of azobisisobutyronitrile pre-dissolved with 50G, drop it in 1.5h, keep warm for 3h, add 2,6-tert-butyl p-cresol, stir well and then add acrylic acid React with N,N dimethylbenzylamine at 110-115°C until the acid value is less than 10mgKOH / g, add 150g of tripropylene glycol diacrylate, cool down to 85°C, and keep the vacuum degree above -0.097 and the temperature at 80 Toluene was distilled under reduced press...

Embodiment 2

[0023] 1. The preparation method of active oligomer is as embodiment 1, but replaces toluene with acetone, ether or any organic solvent.

[0024] 2. The preparation of UV-curable varnish is as in Example 1, but A2 is used instead of A1.

Abstract

The invention provides ultraviolet solidifying gloss oil and a preparation method thereof. The ultraviolet solidifying gloss oil comprises 30 to 65 percent of reactive oligomer, 20 to 60 percent of reactive diluent, 4 to 15 percent of photoinitiator, and 0.1 to 2 percent of additive. The ultraviolet solidifying gloss oil is prepared by the following steps: adding the reactive oligomer, the reactive diluent and the additive in turn into a reaction kettle and agitating the mixture evenly; then adding the photoinitiator and agitating the mixture at a high speed to dissolve the photoinitiator; and finally adding the additive into the reaction kettle. The ultraviolet solidifying gloss oil has excellent adhesion, high brightness and abrasion resistance, and no easy leakage on paper printed work. When the ultraviolet solidifying gloss oil is applied to the printed work and no low oil is required. The ultraviolet solidifying gloss oil is particularly suitable for the direct online glazing on a printer, saves time and reduces the production cost, and has the same good adhesion to non-absorbent objects to be printed such as plastics.

Description

technical field [0001] The invention relates to an ultraviolet light-curable varnish and a preparation method thereof, which is particularly suitable for directly glazing the surface of paper or plastic printed matter without priming. Background technique [0002] In order to ensure good gloss, adhesion, wear resistance, etc., UV-curable varnishes currently used in the market need to apply a layer of primer (water-based or oil-based) before applying UV varnish, adding a process, which is time-consuming and expensive. Increase the cost, and there will be the possibility of paper sticking after priming, and some plastic prints have poor adhesion even with a layer of primer. Contents of the invention [0003] In order to overcome the time-consuming, high cost, and poor adhesion of existing UV-curable varnishes, the present invention provides a primer-free UV-curable varnish, which can be directly applied to paper or plastic printed matter. Glazing, without primer, can guaran...
