UV-LED ink jet printing welding-resistance ink as well as preparation method and application thereof

Abstract

The invention discloses a UV-LED ink jet printing welding-resistance ink as well as a preparation method and application thereof. The UV-LED ink jet printing welding-resistance ink is prepared from the following raw materials in parts by mass: 5-15 parts of modified epoxy monoacrylate, 2-6 parts of a curing agent, 60-80 parts of an active diluent, 3-10 parts of a nanometer color paste, 3-10 partsof a photoinitiator and 0.1-3 parts of an additive, wherein the active diluent is at least one of a single-functional monomer, a double-functional monomer and polyfunctional monomer; and the additiveis at least one of a flow agent and a defoaming agent. The invention also discloses the preparation method and a using method of the UV-LED ink jet printing welding-resistance ink. The UV-LED ink jetprinting welding-resistance ink provided by the invention has the characteristics of good adhesive force, good acid and alkali resistance, good thermal shock resistance, high hardness and the like.

Description

technical field [0001] The invention relates to a UV-LED inkjet printing solder resist ink and a preparation method and application thereof. Background technique [0002] Printed circuit board (PCB) is the provider of electrical connection of electronic components, and plays a very important role in many electronic devices. In the production process of printed circuit boards, in order to improve the welding efficiency and avoid damage to parts that do not need to be welded, these parts need to be protected. At this time, solder resist ink is required. [0003] Traditional printed circuit board solder resist inks can be divided into four categories according to the preparation process, including dry film forming, thermosetting forming, ultraviolet (UV) curing forming and photoimaging curing forming. UV curing molding is widely used because of its fast curing speed, less solvent used, and high line precision. At present, the process of printing circuit board solder resist in...

AI Technical Summary

Problems solved by technology

However, since the heat-curing solder resist ink used in screen printing needs to go through the steps of screen printing, exposure and development during use, the operation is cumbersome, and the development step will generate a large amount of industrial wastewater. Therefore, the ink of the traditional screen printing method exists. To solve the problem of environmental pollution, it is of great significance to develop new environmentally friendly printing inkjet inks
