Abstract

The invention discloses a preparation method of ultraviolet-curing solder resist ink. The ultraviolet-curing solder resist ink is composed of 30-45 parts of photosensitive resin, 2-8 parts of pentaerythritol acrylate and/or derivative thereof, 1-5 parts of hydroxypropyl methacrylate and/or derivative thereof, 1-5 parts of photosensitizer, 10-20 parts of filler, 1-5 parts of colour paste and 1-5 parts of auxiliaries. After grinding, viscosity of the ink is low, the ultraviolet-curing solder resist ink is applicable to being printed on a single sided board of a printed circuit board plant, and the effects of beautifying appearance and protecting circuits are realized; meanwhile, the ultraviolet-curing solder resist ink has excellent smoothness property, insulativity and high heat resisting property after ultraviolet-curing is carried out.

Description

technical field [0001] The invention relates to an ultraviolet light curing solder resist ink, in particular to a new environment-friendly solder resist ink with excellent leveling property, high heat resistance and insulation. Background technique [0002] Traditional UV-curable inks have poor heat resistance after curing, and are prone to foaming or oil loss during soldering, which cannot meet the requirements on high-demand electrical circuit boards. Contents of the invention [0003] The purpose of the present invention is to provide a UV-curable solder resist ink, which is processed through compounding of photosensitive resin, preparation of color paste, mixing, dispersing, grinding, filtering and tank separation. The product of the invention is easy to prepare, has good printing performance, high heat resistance and insulation, and efficiently solves the problem of foaming or oil loss of traditional ultraviolet curing inks when soldering on circuit boards. [0004] ...
