LED UV curing glass ink

Abstract

The invention provides LED UV curing glass ink and mainly solves the technical problems that thermo-curing ink is universally in the existing glass ink industry, the energy consumption is high, the efficiency is low and the like. The main point of the technical scheme is that the glass ink is prepared from the raw materials, by weight, of 30%-60% of resin, 3%-20% of UV monomer, 1%-10% of photoinitiator, 0.1%-5% of auxiliary, 0.1%-10% of pigment and 5%-30% of filler, and the resin comprises organic silicone modified epoxy acrylic resin, polyester acrylic resin, acrylic modified alkyd resin and acrylic modified silicone resin; the UV monomer comprises IBXA, acryloyl morpholine, spiro orthocarbonate, DPHA, (EO)n-TMPTA, tetrahydrofuran acrylate, lauryl acrylate and 9,9'-bis[4-(2'-hydroxy-3'-methacryloyloxypropoxy)phenyl]fluorene. The glass ink is manufactured with an LED UV curing method, has the advantages that energy is saved and the environmental protection efficiency is high and is mainly applied to the glass ink industry.

Description

Technical field

[0001] The invention relates to a glass ink, in particular to an LED UV curing glass ink. Background technique

[0002] UV is the abbreviation of ultraviolet light. In the field of chemical polymers, UV is also referred to as the abbreviation of radiation curing. UV is also UV ultraviolet curing, which uses the medium and short wave (300-800 nanometers) of UV ultraviolet light under UV radiation. The photoinitiator in the liquid UV material is stimulated to become free radicals or cations, thereby initiating the polymerization of polymer materials (resins) containing active functional groups into insoluble / insoluble solid coatings. This is a process that emerged in the 1960s New technologies that are environmentally friendly and low VOC emissions have been rapidly developed in China since the 1980s. In the 21st century, most UV curing uses new types of UV LED curing, including UV LED point light sources, line light sources, and surface light sources. Mercury lam...
