Ultraviolet curing painting capable of being cured at low energy

Abstract

The invention discloses an ultraviolet curing painting capable of being cured at low energy. The ultraviolet curing painting comprises the following components in percentage by mass: 40 to 60 percent of photosensitive resin, 25 to 45 percent of crosslinking diluent, 2 to 12 percent of photoinitiator, 1 to 8 percent of trimethylolpropane tri-sulfenyl ester, and 0.1 to 0.8 percent of ultraviolet storage stabilizing agent. The painting can be cured under natural light irradiation by adding the trimethylolpropane tri-sulfenyl ester and the ultraviolet storage stabilizing agent without higher energy irradiation.

Description

technical field [0001] The invention relates to an ultraviolet light to visible light curing material, in particular to an ultraviolet light curing coating which can be cured under low energy. Background technique [0002] Light-curing coatings are also called photosensitive coatings, and those that use ultraviolet light as the energy source for coating curing are called UV-curing coatings. Ultraviolet (UV) curing coatings do not require heating and can quickly cure into films on flammable substrates such as paper, plastic, leather and wood. UV-curable coatings are mainly composed of photosensitive resins, photosensitizers (photoinitiators) and diluents, while adding some additives, such as heat stabilizers, pigments and fillers when preparing colored paints. [0003] Photosensitive resins are generally low molecular weight resins with unsaturated bonds, such as unsaturated polyesters, acrylic oligomers; photosensitizers are compounds that easily absorb ultraviolet light to...

Problems solved by technology

[0006] People have also found some problems when using UV-curable coatings. 2 -1000 mj / cm 2 It can only be cured under high strength, so the energy consumption is high, and the requirements for the ultraviolet light source are relatively high, so that the traditional ultraviolet curing coating cannot be applied in the environment that is in contact with the human body and requires low energy.

For example, cosmetics containing UV-curable coatings applied to nails or skin, if traditional UV coatings need strong energy to cure, this will cause greater harm to the human body
