Example Embodiment
[0059] figure 1 Shown is a flow chart of a method for preparing photosensitive solder resist ink according to an exemplary embodiment of the present disclosure. Some embodiments of the present disclosure also provide a method for preparing any of the above-mentioned photosensitive solder resist inks, refer to figure 1 , The preparation method of photosensitive solder resist ink includes:
[0060] Step 11. According to the weight parts of each component, a first mixture of resistance adjusting agent, surfactant, and first coupling agent is configured.
[0061] Among them, the first coupling agent can improve the interface performance between the resistance adjusting agent and other components, and the resistance adjusting agent can be uniformly dispersed in the first mixture through the combination of the first coupling agent and the surfactant.

Example Embodiment
[0084] Example 1
[0085] This embodiment provides a photosensitive solder resist ink, and its preparation method includes:
[0086] According to the parts by weight of each component, 2 parts of conductive carbon black and 2 parts of short carbon nanotubes are mixed and added to absolute ethanol, and ultrasonic dispersion treatment is performed. 0.5 part of sodium dodecylbenzene sulfonate was added to the mixture of conductive carbon black, short carbon nanotubes and absolute ethanol, and ultrasonic dispersion treatment was carried out. The power of the ultrasonic dispersion treatment was 400W and the temperature was 30°C. Add 2 parts of silane coupling agent KH550 to the mixture of conductive carbon black, short carbon nanotubes, absolute ethanol and sodium dodecylbenzene sulfonate, and stir for 2 hours at a stirring speed of 400 rpm to obtain a first mixture.
