Abstract

The invention discloses an UV-curing coating. The UV-curing coating comprises the following components in parts by weight: 16-25 parts of bisphenol A epoxy acrylate resin, 4-10 parts of phenolic epoxy acrylate, 8-15 parts of epoxidation oil propionate, 10-25 parts of active diluents, 1-5 parts of photoinitiators, 6-12 parts of organic amine, 1-4 parts of auxiliary agents and 30-50 parts of a solvent. The UV-curing coating is used for making a printed circuit board and a substrate which has difficult adherence performance or a soft base material, the UV-curing coating has the advantages of fast light-curing speed of the coating, high coating hardness, good corrosion resistance, good heat resistance, good wetability, light irritation on skin, easy acquisition of the raw materials, and low cost.

Description

technical field [0001] The invention relates to the technical field of preparation of environmentally friendly coatings, in particular to an ultraviolet curing coating. Background technique [0002] UV curing coating (UVCC for short) is an environmentally friendly and energy-saving coating developed in the 1960s. Since it was commercialized abroad in the 1970s, it has maintained an average annual growth rate of 8%-10%. Speed. Its advantage lies in fast curing speed, almost instantaneous film formation, less use of volatile solvents, high efficiency and energy saving, automatic operation of the curing process, suitable for continuous large-scale production. UVCC meets the current worldwide increasing emphasis on environmental protection requirements, and is known as It is a new generation of environmentally friendly products. Its curing light sources are generally ultraviolet light (UV), electron beam (EB) and visible light. Due to the complexity of electron beam curing equip...
