Stain-resisting ultraviolet curing painting

Abstract

The invention discloses a stain-resisting ultraviolet curing painting, which comprises the following components in percentage by mass: 35 to 55 percent of photosensitive resin, 20 to 40 percent of crosslinking diluent, 2 to 12 percent of photoinitiator, and 10 to 25 percent of fluorine modified resin. By adding the fluorine modified resin into the formula, the stain-resisting ultraviolet curing painting is hydrophobic and oleophobic under the action of fluorine with lower surface tension, so the stain-resisting ultraviolet curing painting has the characteristic of stain resistance.

Description

technical field [0001] The invention relates to an ultraviolet light to visible light curing material, in particular to a stain-resistant ultraviolet light curing coating. 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 generate active free...

Problems solved by technology

[0006] People have also found some problems when using UV-curable coatings. For example, when traditional UV-curable coatings are used on electronic products, fingerprints will be left on the surface after being touched by human hands, and it is easy to get dusty, which affects the aesthetics.
