Environment-friendly and energy-saving UV (Ultraviolet) printing ink

Abstract

The invention discloses environment-friendly and energy-saving UV (Ultraviolet) printing ink. The environment-friendly and energy-saving UV printing ink is prepared by mixing resin, 2,4,6 (trimethylbenzoyl)diphenylphosphine oxide, an aminoethylaminopropyl trimethoxysilane coupling agent, organic pigment, filling, a de-foaming agent and a flatting agent. The environment-friendly and energy-saving UV printing ink disclosed by the invention is high in UV light curing efficiency; the light curing time is about 5s and a post-heating process is not needed; environmental friendliness and energy saving are realized: the UV printing ink is applied to a colored crystal industry and the energy consumption is greatly reduced; and the utilization time is short, so that the energy consumption is greatly reduced. A cured film has high covering power, the rigidity of 3H and excellent wearing resistance and adhesive force; and after an adhesion test, the environment-friendly and energy-saving UV printing ink is 100% not released. The environment-friendly and energy-saving UV printing ink has excellent water resistance; a formula contains no volatile organic solvents and no irritating odor, and a screen is not plugged in a screen-printing process; and the reproducibility of screen points is good and convenience is provided for manufacturing a high-precision pattern. The environment-friendly and energy-saving UV printing ink is especially suitable for printing a glass substrate.

Description

Technical field [0001] The invention relates to the field of inks, in particular to an environmentally friendly and energy-saving UV ink. Background technique [0002] Traditional glass inks are generally composed of resins, pigments, solvents, additives and fillers. In solvent [0003] And resins often contain volatile organic compounds (V O C ), most of them are toxic, and the solvent content in solvent-based glass inks generally exceeds 30% of the total ink, and some solvents must be added to adjust the viscosity during use. Most of the organic solvents do not participate in the reaction and are released into the air during printing construction, causing pollution. In addition to solvent volatilization, the ink layer needs to be baked at a high temperature to dry during the printing construction process, which consumes a lot of energy; at the same time, because the raw materials may contain amino resins, as the baking time increases and the temperature increases, the free The...

Problems solved by technology

During printing construction, most of the organic solvents do not participate in the reaction and are released into the air, causing pollution

In addition to the volatilization of the solvent, the ink layer needs to be baked at high temperature to dry during the printing construction process, which consumes a lot of energy; at the same time, because the raw materials may contain amino resin, with the extension of the baking time and the increase of temperature, the self-sufficiency of the amino resin will decrease. The shrinkage reaction will also release harmful substances such as formaldehyde

At present, the solvent-based glass ink used in the market will also cause the collapse of the printing dots due to the volatilization of the solvent during the construction and printing process, so there are certain difficulties in making high-precision patterns.
