Problems solved by technology

[0003] Existing screen printing inks are used on electronic products with polyvinyl chloride shells. Most of the non-special inks used are adhesive type, which have poor affinity with the substrate and are easy to fall off.
Poor effect, mainly due to poor adhesion, easy to fall off the printing; moreover, the printing ink itself is easy to oxidize; the shelf life is short

Abstract

The invention discloses silk-screen printing ink based on a PVC (polyvinyl chloride) substrate. The silk-screen printing ink comprises components in parts by weight as follows: 20-30 parts of PVC resin, 1-6 parts of polypropylene glycol, 2-8 parts of polyester resin, 5-10 parts of isobutyl methacrylate, 3-7 parts of tetrahydrofuran, 2-7 parts of an antifoaming agent, 3-9 parts of a leveling agent, 5-12 parts of a coupling agent, 5-15 parts of nanofiller and 30-40 parts of a solvent. The prepared silk-screen printing ink has good leveling property when printed on a PVC material and is suitable for fine silk-screen printing; meanwhile, with adding of the coupling agent and the nanofiller, the silk-screen printing ink has better adhesiveness and better abrasive resistance and glossiness and is applicable to the field of silk-screen printing of electronic and electrical products and the like containing a PVC casing.

Description

technical field [0001] The invention relates to the field of inks, in particular to a screen printing ink based on a PVC substrate. Background technique [0002] Screen printing ink refers to all inks used when screen printing is used. With social progress and economic development, electronic and electrical products are widely used, product development is changing with each passing day, operating systems are becoming more and more intelligent, high-performance electronic products are High-end inks are required for decoration and protection. [0003] Existing screen printing inks are used on electronic products with polyvinyl chloride shells. Most of the non-special inks used are adhesive type, which have poor affinity with the substrate and are easy to fall off. The effect is poor, mainly due to poor adhesion, and the printing ink is easy to fall off; moreover, the printing ink itself is easy to oxidize; the shelf life is short.
