Ultraviolet light curing material

Abstract

The present invention relates to an ultraviolet light curing material, which comprising the following components by weight percentage: 40-60%of light cured resin; 25-45% of light curing diluent; 2-10% of photoinitiator; 0-0.8% of ultraviolet storage stabilizer; 0.5-30%of nano filler; 0.2-1% of leveling agent. On the basis of addition of light cured resin, the light curing diluent and the photoinitiator in the ultraviolet light curing material, the nano filler is added, the ultraviolet light respectively reflects to all directions through small particles, so that the light is scattered, the utilization rate of the ultraviolet light can be increased, the crosslinking and curing speed can be accelerated, and the curing energy can be reduced.

Description

technical field [0001] The invention relates to an ultraviolet light curing material, in particular to an ultraviolet light curing material capable of curing under low energy. Background technique [0002] Light-curing materials are also called photosensitive materials, and those that use ultraviolet light as the material curing energy are called ultraviolet light-curing materials. Ultraviolet (UV) curing materials do not need to be heated, and can be quickly cured into a film by ultraviolet radiation. UV curable materials are mainly composed of photocurable resin, photoinitiator and diluent, and some additives are added at the same time. [0003] Photocurable resins are generally low molecular weight resins with unsaturated bonds, such as unsaturated polyesters, acrylic oligomers; photoinitiators are compounds that generate active free radicals by absorbing ultraviolet light, such as benzophenone and benzoin Base ethers; the main function of the diluent is to adjust the v...

Problems solved by technology

[0006] There are also some problems when using UV-curable materials. For example, traditional photo-curable materials need to be at 600mj / cm 2 ~2000Mj / cm 2 It can only be cured under high strength, which requires high energy consumption and relatively high requirements for ultraviolet light sources, so that traditional ultraviolet curing materials cannot be used in environments that are in contact with the human body and require low energy.

At present, the way to reduce the curing energy is mainly by increasing the functionality of the photocurable resin and the monomer, which is partially cured to reduce the curing energy, and also by using a special structure, such as mercapto resin, which has high reactivity, but its Unstable, difficult to store, inconvenient to transport and other issues, so providing a low-energy UV-curable material is a technology that the industry has been longing for
