Abstract

The invention relates to the field of ink, in particular to a thermoset solder resist ink composition. The thermoset solder resist ink composition is prepared from, by weight, 15-30 parts of linear polymers of which the end group is carboxyl, 10-25 parts of hyperbranched resin, 5-20 parts of reactive diluents, 10-35 parts of inorganic filler, 0-15 parts of pigments, 0-8 parts of functional promoter, 0-20 parts of solvents and 1-3 parts of curing agents. Compared with home-produced traditional thermoset solder resist ink, the prepared thermoset solder resist ink has the advantages of being low in curing temperature, excellent in thermal resistance, soldering resistance and yellowing resistance and the like, and the thermoset solder resist ink is high in curing speed and specially suitable for solder resist ink for LEDs.

Description

technical field [0001] The invention relates to the field of inks, in particular to a thermosetting solder resist ink composition. 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 solder resist inks often have high curing temperature 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 thermosetting solder resist ink composition with low curing temperature and good heat resistanc...
