Problems solved by technology

As the production process requirements of membrane switches, electronic panels and buttons are getting higher and higher, their use is gradually restricted
For example, the European GS certification has made PAHS a mandatory testing item, while traditional solvent-based PET screen printing inks often contain harmful substances such as halogens and PAHS

Embodiment 1

[0086] Take 70.2 parts (weight) of polyester resin liquid, 6.8 parts (weight) of aldehyde and ketone resin, add 0.5 parts (weight) of wetting agent, and after the formed mixture is uniformly dispersed at a low speed of 400-500RPM, slowly add 0.8 parts of thickener (weight) and then stir for 10 minutes, then add 10 parts (weight) of carbon black, 5 parts (weight) of filler, after grinding, add 1.5 parts (weight) of defoamer, 5.2 parts (weight) of isophorone solvent, and disperse evenly Finally, filter with 200 mesh to get the finished product.

Embodiment 2

[0088] Take 47.5 parts (weight) of polyester resin liquid, 5.7 parts (weight) of aldehyde and ketone resin, add 0.5 parts (weight) of wetting agent, and disperse the formed mixture evenly at a low speed of 400-500RPM, then slowly add 0.5 parts of thickener (weight), then stir for 10 minutes, then add 45 parts (weight) of titanium dioxide, 5 parts (weight) of filler, and add 1.5 parts (weight) of defoamer after grinding by three-roller machine, disperse evenly and filter with 200 mesh gauze , the finished product is obtained.

Embodiment 3

[0090] Take 90 parts (weight) of polyester resin liquid, 8 parts (weight) of aldehyde and ketone resin, add 1 part (weight) of defoamer, 1 part (weight) of filler, and disperse evenly at a high speed of 800-1200 RPM, then use 200 mesh mesh Filter to get the finished product.

[0091] The printing effect and physical and chemical index state of the environmentally friendly ink without halogen and PAHS obtained in the above examples are shown in figure 1 shown.

Abstract

The invention discloses a silk-screen printing ink for a polyethylene terephthalate (PET) material. The ink is composed of the following components in percentage by weight: 50-92% of polyester resin solution, 5-15% of aldehyde and ketone resin solution, 0.5-2% of defoamer, 0-0.5% of wetting agent, 0.5-3% of thickener and 0.5-2% of filler. The silk-screen printing ink for the PET material effectively overcomes the applicable limitation of the traditional ink for the PET material, has good resistance to viscose glue, has the characteristics of wide applicable materials, and is suitable for various PET materials. Because the ink disclosed by the invention mainly comprises polyester resin and an appropriate amount of auxiliary agents and filler, the ink has excellent use performance, has goodink layer leveling property and high hiding rate when used for silk-screen printing of PET and hardened surfaces, is suitable for high-mesh fine silk-screen printing, and has the advantages of dry ink layer, strong adhesion force of a coating film to the material, excellent water resistance, acid resistance, base resistance and impact resistance, and excellent temperature resistance, scratch and scrape resistance and glue water resistance.

Description

technical field [0001] The invention relates to screen printing inks, in particular to a screen printing ink for non-halogen and PAHS (polycyclic aromatic hydrocarbons) environment-friendly PET (polyethylene terephthalate) materials. Background technique [0002] Along with social progress and economic development, electronic and electrical products are widely used, the products are changing day by day, and the operating system is intelligent. Among them, the production process improvement of membrane switch and electronic panel and the surface hardening treatment of materials are various, and inks with high performance requirements are usually used for decoration and protection. As the production process requirements of membrane switches, electronic panels and buttons are getting higher and higher, their use is gradually restricted. For example, European GS certification has adopted PAHS as a mandatory testing item, while traditional solvent-based PET screen printing inks ...
