Abstract

The invention relates to the field of ink, in particular to thermal resistant light curing solder resist ink. The thermal resistant light curing solder resist ink is prepared from, by weight, 20-30 parts of polyurethane modified acrylic resin, 25-40 parts of hyperbranched resin, 20-40 parts of reactive diluents, 10-15 parts of inorganic filler, 0-15 parts of pigments, 0-6 parts of functional promoter and 2-6 parts of photoinitiator. Compared with home-produced traditional solder resist ink, the thermal resistant light curing solder resist ink has the advantages of being high in curing speed, strong in adhesive force, excellent in thermal resistance, soldering resistance and yellowing resistance and the like, and the thermal resistant light curing solder resist ink is specially suitable for solder resist ink for LEDs.

Description

technical field [0001] The invention relates to the field of inks, in particular to a heat-resistant photocurable solder resist ink. Background technique [0002] Solder resist ink is one of the key materials in the chemicals used in the manufacture of printed circuit boards. It can prevent scratches on the wires and short circuits between the wires during soldering. At the same time, it can also make the wires moisture-resistant, chemical-resistant, Therefore, the research and development of solder resist ink has always occupied a very important position in the progress of printed circuit board technology. However, the existing light-curable solder resist inks often have slow curing speed and poor heat resistance, which is not conducive to the further use of solder resist inks. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a photocurable solder resist ink with fast curing speed and good heat resistance. ...
