Problems solved by technology

[0003] However, the effect of curing traditional UV varnish with this LED light source curing system is not good, because the traditional UV varnish curing uses the entire ultraviolet spectrum of 200-400nm, and the light emitted by this LED light source curing system is mainly concentrated at 360 -405nm, so when the traditional UV varnish is cured by this LED light source curing system, the surface will not be completely dry, resulting in sticky surface, low hardness, poor wear resistance, low curing speed (5-10m / min), production Low efficiency and other disadvantages

Abstract

The invention relates to UV gloss oil capable of being used for UV-LED light source rapid curing and a preparation method of the UV gloss oil. The UV gloss oil comprises, in parts by weight, 55-70 parts of light-cured resin, 10-40 parts of a reactive diluent, 1-10 parts of a photoinitiator, 0.1-3 parts of a co-initiator, 0-2 parts of a flatting agent and 0-2 parts of a defoaming agent. The light-cured resin is prepared by selecting 50 to 70 parts by weight of hyperbranched acrylic resin and 0 to 20 parts by weight of organic silicon polyurethane acrylate and mixing. According to the UV gloss oil capable of being used for rapid curing of the UV-LED light source and the preparation method of the UV gloss oil, the reactive diluent with the high boiling point is adopted to replace a common organic solvent, the pollution problem of the organic solvent is solved, and complete non-toxicity is achieved; and meanwhile, the reactive diluent is hydrogen-donating ether acrylate, and oxygen inhibition can be effectively inhibited.

Description

technical field [0001] The invention relates to the technical field of UV varnish, in particular to a UV varnish which can be used for rapid curing of UV-LED light sources and a preparation method thereof. Background technique [0002] UV curing refers to the process in which the cured material absorbs a certain band of ultraviolet light to undergo a cross-linking polymerization reaction after being irradiated by ultraviolet light, and instantly changes from a liquid state to a solid state. Conventional UV light sources are high-pressure mercury lamps, which have problems such as short life, high power consumption, thermal deformation of printing materials, and heavy metal pollution. The UV-LED light source uses the principle of photoelectric conversion. The electrons and positive charges in the chip collide and combine into light energy during the moving process, making UV-LED curing more energy-saving and environmentally friendly, and the light source has a long life and l...
