Problems solved by technology

[0003] However, the current high-end inks often contain some harmful substances. For example, traditional aluminum foil and PET composite materials often contain harmful substances such as halogens and PAHS in screen printing inks.
This severely limits the use of inks in the production of membrane switches, electronic panels and keys for electronic products

Embodiment 1

[0023] Take 60wt% polyester resin, add 1wt% additive, mix evenly, then add 9wt% carbon black and 30wt% filler, and stir for 10 minutes. After stirring evenly, grind on a three-roller machine to make the particle size of the solid particles smaller and uniform. Finally, filter with gauze, the gauze is 200 mesh. After drying, the finished screen printing ink is obtained.

Embodiment 2

[0025] Take 50wt% polyester resin, add 0.8wt% additives, mix evenly, then add 6wt% carbon black and 35wt% filler, and stir for 10 minutes. After stirring evenly, grind on a three-roller machine to make the particle size of the solid particles smaller and uniform. Finally, filter with gauze, the gauze is 200 mesh. After drying, the finished screen printing ink is obtained.

Embodiment 3

[0027] Take 70wt% polyester resin, add 1.6wt% additives, mix well, then add 10wt% carbon black and 40wt% filler, and stir for 15min. After stirring evenly, grind on a three-roller machine to make the particle size of the solid particles smaller and uniform. Finally, filter with gauze, the gauze is 200 mesh. After drying, the finished screen printing ink is obtained.

Abstract

The invention discloses screen printing ink which comprises the following components in percentage by weight: 50-70% of polyester resin, 30-40% of filler, 5-10% of toner and 0.5-2% of assistant. The screen printing ink disclosed by the invention can be used for effectively overcoming the adaptive limitation of printing ink for conventional aluminum foils and PET (Polyethylene Glycol Terephthalate) composite materials (embodiment 719), and has remarkable improvement on the coating effect of a printing face, so that the yield in the production process is improved, and the cost is lowered. Meanwhile, the printing ink disclosed by the invention mainly comprises polyester resin and adaptive assistant and filler, so that the printing ink has excellent using performance, and when the printing ink is used for printing aluminum foils and PET composite materials, the ink layer is good in leveling property and high in obscuring ratio. Therefore, the printing ink is suitable for high-mesh exquisite screen printing and good in adhesion, and has excellent water-resisting, alkali-resisting and acid-resisting performances and wash-resisting performance and excellent temperature-resisting, scratch-resisting, scrap-resisting and glue-resisting performances.

Description

technical field [0001] The invention relates to silk screen printing ink, in particular to an environment-friendly screen printing ink applicable to aluminum foil and PET composite materials. Background technique [0002] With social progress and economic development, electronic and electrical products are widely used, product development is changing with each passing day, and operating systems are becoming more and more intelligent. Among them, especially with the improvement of the production process of membrane switches, electronic panels and buttons of electronic products, and the diversity of material surface hardening treatments, electronic products with higher performance have been produced. The above-mentioned high-performance electronic products all require high-end inks for decoration and protection. [0003] However, the current high-end inks often contain some harmful substances. For example, traditional aluminum foil and PET composite materials often contain ha...
