[0071] Resin Synthesis Example

[0072] Synthetic Example 1 (photosensitive resin 1)

[0073] In the reactor, add 200g novolac epoxy resin CNE-202 (Taiwan Changchun Life Resin Factory, epoxy equivalent 210), 250g propylene glycol methyl ether acetate (PMA), 69g acrylic acid, heat and melt, then add 0.5g p-phenylene Diphenol and 1.5 g of triphenylphosphine were reacted at 110° C. for 12 hours to obtain a product with an acid value of less than 5. Then add 85g of tetrahydrophthalic anhydride, heat to 100°C, and react for 6 hours to obtain light yellow resin solution A1 (photosensitive resin 1), with an acid value of 52mgKOH / g, a solid content of 59%, and a Mw of about 2000 .

[0074] Synthetic Example 2 (photosensitive resin 2)

[0075] Add methyl methacrylate, butyl methacrylate and acrylic acid in the reactor according to the molar ratio of 1:1:2, use carbitol acetate as the solvent, and use azobisisobutyronitrile (AIBN) as the catalyst , stirred at 80° C. for 4 hours to o...

Abstract

The invention provides a composition capable of resisting oxygen inhibition and improving surface curing degree of photo-cured printing ink and application. The composition comprises an organosiliconleveling agent and sulfydryl-containing mercaptan. According to the composition capable of resisting oxygen inhibition and / or improving surface curing degree of photo-cured printing ink disclosed by the invention, the cross-linking degree of the ink is improved, the film retention rate of the printing ink is further improved, the adhesive force of the printing ink attached to the coated surface isimproved, and the photo-electric sensitivity, corrosion resistance and other chemical resistant properties of the printing ink are improved.

Description

technical field [0001] The invention belongs to the field of circuit board inks, and in particular relates to a composition which resists oxygen resistance and improves the surface curing degree of photocurable inks, a preparation method thereof and an application in printed circuit boards, belonging to cured coatings in electronic materials. Background technique [0002] UV-curable coatings (such as ink compositions) are high-efficiency and environmentally friendly green coatings, which are cured by initiating a chain polymerization reaction between reactive substances under the irradiation of ultraviolet light. Specifically, UV curing refers to the technology of instantaneous polymerization and crosslinking of organic formula material systems under ultraviolet light irradiation. , ink, adhesive field. Compared with traditional solvent-based heat-curing coatings, UV-curing coatings (such as ink compositions) have the advantages of low VOC emissions, fast curing speed, low ...
