Embodiment 1

[0049] Under normal temperature and pressure, take 35 parts (weight) of ether solvent, add 30 parts (weight) of acrylic resin, 20 parts (weight) of epoxy resin, mix with a mixer, and stir at a speed of 600-1000RPM for 10-20MIN to dissolve After completion, add 1 part (weight) of dispersant and 12.5 parts (weight) of pigment, stir evenly, and then grind it with a three-roller machine to a fineness below 10 μm, then add 1.5 parts (weight) of defoamer, stir and disperse evenly to obtain the finished product.

Embodiment 2

[0051] Under normal temperature and pressure, take 30 parts (weight) of ether solvent, add 30 parts (weight) of acrylic resin, 25 parts (weight) of epoxy resin, mix with a mixer, and stir at a speed of 600-1000RPM for 10-20MIN to dissolve After completion, add 1 part (weight) of dispersant and 12.5 parts (weight) of pigment, stir evenly, and then grind it with a three-roller machine to a fineness below 10 μm, then add 1.5 parts (weight) of defoamer, stir and disperse evenly to obtain the finished product.

[0052] The low-temperature curing electroplating surface screen printing ink obtained in the above examples is shown in the effect of 300 mesh screen printing and the state of physical and chemical indicators on the electroplating surface material. figure 1 .

Abstract

The invention discloses a low-temperature solidifying electroplating surface screen printing ink, which is composed of the following components in percentage by weight: 20-40% of acrylic resin, 10-30% of epoxy resin, 25-35% of solvent, 5-35% of pigment, 0.1-5% of dispersing agent and 0.1-5% of defoamer. The solvent used in the ink disclosed by the invention is environmentally-friendly, is free of PAHS (polycyclic aromatic hydrocarbon), can be solidified at low temperature and is naturally volatilized. Surface drying time is 5-10min, hard drying time is 24 hours, or the solvent can be completely solidified if being baked at 80DEG C for 20min. In addition, the solvent has the advantages of high hardness, excellent adhesive force, chemical resistance, high efficacy and energy saving, is environmentally friendly and is convenient to use.

Description

technical field [0001] The invention relates to silk screen printing ink, in particular to a low-temperature curing electroplated screen printing ink. Background technique [0002] The process of some electroplating products includes spraying, blistering, etc., which cannot be baked at high temperature. However, most of the electroplated screen printing inks and coatings on the market are high-temperature curing systems, and the baking temperature is 120-180°C. Higher temperatures are required to achieve high hardness, adhesion, and chemical resistance. This not only leads to waste of resources, but also runs counter to the social development theme of promoting high efficiency, energy saving, and environmental protection. [0003] Therefore, the prior art needs to be perfected and developed. Contents of the invention [0004] In view of the above deficiencies in the prior art, the purpose of the present invention is to provide a screen printing ink that can be cured at lo...
