Problems solved by technology

[0004] The advantages of light-curing coatings are short curing time (a fraction of a second to a few minutes), low curing temperature, and low volatile matter. They are energy-saving, resource-saving, pollution-free, and high-efficiency new types of coatings; The curing process of light-curing coatings is inhibited by oxygen, and the surface curing is poor

Abstract

The invention discloses an antibacterial ultraviolet-curable coating, which comprises the following components in percentage by mass: 40 to 60 percent of aromatic polyurethane-acrylate, 25 to 45 percent of crosslinking thinner, 2 to 12 percent of photoinitiator, 5 to 15 percent of nano silicon dioxide, and 0.5 to 1 percent of silver oxide. The nano silicon dioxide is susceptible to agglomeration in the system, so if the nano silicon dioxide is not dispersed uniformly, the transparency and wear resistance of the system may be influenced; and nano silicon dioxide grafted on dipentaerythritol hexaacrylate can well keep the transparency and wear resistance of the system. The combination of silver oxide and aromatic polyurethane-acrylate produces a desirable antibacterial effect.

Description

technical field [0001] The invention relates to an ultraviolet light to visible light curing material, in particular to an antibacterial 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 ...
