[0069] Examples 1~6 and Comparative Examples 1~3
[0070] The usage amount of the raw materials of Examples 1 to 6 calculated in parts by mass is shown in Table 1;
[0071] The usage amount of the raw materials of Comparative Examples 1-7 calculated by mass parts is shown in Table 2.
[0072] The preparation method of the above-mentioned high temperature resistant UV-LED inkjet printing solder mask ink is as follows:
[0073] S1. Stir the phenolic epoxy resin, light-curing acrylic resin, phenolic resin, benzoxazine resin, and nano-color paste at a speed of 1000r / min for 1 hour and mix uniformly, for later use;
[0074] S2. Dissolve the photoinitiator in the active diluent, mix well, and set aside;
[0075] S3. Mix the mixture of resin and color paste, curing agent, photoinitiator-dissolved monomer, and additives, stir at 1000r / min for 1h, and filter through a 1 micron filter membrane to obtain a green high-temperature resistant UV -LED inkjet printing solder mask ink.
