Embodiment 1~6 and comparative example 1~3

[0070] The consumption of the raw material of embodiment 1~6 is as shown in table 1 by mass parts;

[0071] The usage amounts of the raw materials in Comparative Examples 1-7 are shown in Table 2 in terms of parts by mass.

[0072] The preparation method of the above-mentioned high-temperature-resistant UV-LED inkjet printing solder resist ink is as follows:

[0073] S1. Stir novolac epoxy resin, photocurable acrylic resin, phenolic resin, benzoxazine resin, and nano-color paste at 1000r / min for 1 hour to mix evenly, and set aside;

[0074] S2. Dissolve the photoinitiator in the reactive diluent, mix well, and set aside;

[0075] S3. Mix the mixture of resin and color paste, curing agent, monomer dissolved in photoinitiator, and additives, stir at 1000r / min for 1 hour, and then filter through a 1-micron filter membrane to obtain a green high-temperature-resistant UV - LED inkjet printing solder resist ink.

[0076] Various tests were performed on the high temperature resist...

Abstract

The invention discloses high-temperature-resisting type UV-LED (Ultraviolet-Light Emitting Diode) inkjet printing solder-resisting ink as well as a preparation method and application thereof. The high-temperature-resisting type UV-LED inkjet printing solder-resisting ink is prepared from the following components in parts by mass: 2 to 10 parts of phenolic epoxy resin, 2 to 10 parts of photo-curingacrylic resin, 1 to 5 parts of first phenolic resin, 1 to 5 parts of second phenolic resin, 1 to 4 parts of curing agent, 40 to 80 parts of active diluting agent, 3 to 10 parts of nano color paste, 3to 10 parts of photoinitiator and 0.1 to 1 part of auxiliary agent; the second phenolic resin is benzoxazine resin; the first phenolic resin is other phenolic resin except the benzoxazine resin; themass ratio of the phenolic epoxy resin to the first phenolic resin to the second phenolic resin is 2 to (0.5 to 1.5) to (0.5 to 1.5). The high-temperature-resisting type UV-LED inkjet printing solder-resisting ink provided by the invention has good high-temperature-resisting performance, good adhesive force, good acid and alkali resistance, good heat impact resistance, high rigidity and the like.

Description

technical field [0001] The invention relates to the technical field of solder resist ink for printed circuit boards, and more specifically, to a high temperature resistant UV-LED inkjet printing solder resist ink and its preparation method and application. Background technique [0002] Printed circuit board (PCB) is the support body of electronic components and the carrier of electrical connection of electronic components. In the production process of printed circuit boards, in order to protect the non-soldered parts from being damaged, the protection of solder resist ink is required at this time. [0003] Traditional printed circuit board solder resist inks are mainly dry film forming, thermal curing forming, ultraviolet (UV) curing forming and photoimaging curing forming. UV curing molding is widely used because of its fast curing speed, no solvent or less solvent used, and high line precision. At present, the process of printing circuit board solder resist ink is genera...
