Problems solved by technology

However, when UV ink is applied to flexible electronic components, its adhesion to flexible substrates such as PET, PP, and PE is poor, and it will also affect the conductivity of conductive materials such as conductive silver paste. In view of the above problems, it is urgent to develop a UV ink in the market. A high-performance UV ink applied to flexible electronic components that has good adhesion to flexible substrates and does not affect the conductivity of conductive materials

Abstract

The invention relates to high performance UV ink and a preparation method and application thereof. The ink comprises, by weight, 25-45 parts of epoxy acrylate resin, 8-12 parts of saturated polyesterresin, 2-5 parts of methacrylate phosphate, 15-25 parts of 1,6-hexanediol diacrylate, 5-7 parts of tetrahydrofuran acrylate, 0.5-1 part of fumed silica, 3-5 parts of a photoinitiator, 0.5-1 part of toner, 25-40 parts of a filler and 1-3 parts of an auxiliary agent. The ink has good adhesion on a flexible substrate, is applied to a flexible electronic component, has no influence on the electrical conductivity of a conductive material such as conductive silver paste, and can well protect a conductive line and prevent oxidative discoloration of the conductive line.

Description

technical field [0001] The invention relates to the field of UV ink, in particular to a high-performance UV ink and its preparation method and application. Background technique [0002] UV (ultraviolet, ultraviolet) curing technology is a material surface treatment technology that appeared in the 1960s. It has the characteristics of high efficiency, environmental protection, energy saving, high quality, and low investment. It is known as a new technology for green industry in the 21st century. . UV ink is the most common type of light-curing products, and has been widely used in the printing and packaging industry and the optoelectronics industry. UV ink is cured by UV irradiation at room temperature, and its energy consumption is only 10-20% of that of thermal curing. It is an energy-saving product. Its other advantage is that it does not contain volatile organic compounds, and the diluent used is acrylic acid with a high boiling point. Functional monomers participate in ...
