Embodiment 1

[0103] Compared with Example 1, Examples 10-12 replaced C1 with C2, C3, and C4. The viscosity of Example 11 was too low, and the viscosity of Example 12 was too high. It shows that tetrahydrofuran methacrylate can reach the reasonable range of viscosity of jet printing ink.

[0104] In Comparative Example 1-2, the ratio of A1, B1, and C2 was replaced, and the insulation reliability test and solder thermal shock resistance test failed to meet the standards.

Abstract

The invention discloses UV jet printing ink with high adhesive force and good bending property. The UV jet printing ink is prepared from the following components in parts by weight: 8 to 25 parts of acid anhydride, 8 to 20 parts of epoxy acrylate resin, 30 to 75 parts of diluting monomer and 3 to 7 parts of photoinitiator, wherein the anhydride is monofunctional aromatic organic anhydride; the epoxy acrylate resin is epoxy acrylate resin with functional groups 1-2, and the diluting monomer is aliphatic ring or benzene ring substituted acrylate and / or methacrylate. The ink has the characteristics of strong adhesive force, good bending property, excellent jet printing performance and good impact resistance, and effectively solves the technical problem that high adhesive force and good bending property cannot be met at the same time.

Description

【Technical field】 [0001] The invention belongs to the technical field of jet printing inks, in particular to a UV jet printing ink with high adhesion and good bendability. 【Background technique】 [0002] When forming characters and color blocks on a printed circuit board, the printed circuit board characters and color blocks are usually sprayed on the substrate by an inkjet printer. During the spraying process, it is cured by UV light, and then through subsequent baking and tin bleaching And other operations to verify the basic characteristics of the ink, and then form the printing ink. In recent years, ink substrates have become more and more mature. However, most of the inks currently on the market have a decline in adhesion after baking during the process of spraying characters. [0003] In order to avoid this situation, the ink formula is usually improved to improve the post-baking adhesion of the ink. Although the post-baking adhesion can be improved by changing the in...
