Abstract

The invention relates to the technical field of photocureable coatings, in particular to an anti-oxidation polymerization inhibition UVLED coating. A UVLED lamp is used as a light source to carry out light curing on a paint system, and the surface of a paint film is easily influenced by oxygen inhibition, so that the surface hardness, the scratch resistance and the wear resistance of the paint film are poor. In order to solve the problems, the invention provides the anti-oxygen-inhibition UVLED coating, the self-made modified acrylic resin structure in the formula contains a large number of ethyoxyl groups, on one hand, alpha-H in the ethyoxyl groups is easily substituted by oxygen, and the reaction can consume part of oxygen in the system; on the other hand, the alpha-H can terminate peroxide free radicals formed by free radicals and oxygen to form new active free radicals, so that the polymerization inhibition effect of oxygen on the photocuring process is reduced.

Description

technical field [0001] The invention relates to the technical field of photocurable coatings, in particular to an anti-oxidative and polymerization-inhibited UVLED coating. Background technique [0002] In the light-curing coating system, the mercury lamp is the most commonly used. Although the mercury lamp has high energy, wide ultraviolet wavelength range and high light curing efficiency, the use of the mercury lamp will generate ozone molecules, which are harmful to human health and the ozone layer in the atmosphere. are very dangerous. [0003] UVLED lamps are energy-saving and environmentally friendly, with low heat release, long life, and no ozone generation. However, its conventional wavelength bands are 405, 395, 385, 365 nm, etc., all of which are medium and long wavelength bands. The matching degree between the wavelength of the light source and the absorption peak of the photoinitiator is not high, resulting in less free radicals, and the surface of the paint fil...
