Problems solved by technology

[0003] Existing mirror silver paste inks prepared by using ultra-thin electroplating aluminum paste will have a large amount of diffuse reflection after the electroplating surface is formed, which will deteriorate the metal mirror effect, so it can only be used in large quantities for surface processing of small surfaces. Cracking will occur during the later hot pressing forming process, so it can only be used for flat materials
Moreover, the shelf life of the ink is short, and the storage conditions are harsh and difficult to preserve

Abstract

The invention relates to the technical field of electroplating ink, and discloses single-component low-temperature curing imitation electroplating ink, wherein a formula of the ink is prepared from the following components: 5-15 parts by weight of acrylic resin, 0.5-1.5 parts by weight of phenoxy resin, 10-40 parts by weight of silver powder of which the particle size D100 is less than or equal to 200 nm, 50-80 parts by volume of a solvent, 0.1-0.3 part by volume of a leveling agent, 1-3 parts by volume of a defoaming agent, 0.25-1.5 parts by volume of a coupling agent, 0.1-0.5 part by volume of a wetting agent, 0.05-0.2 part by volume of an anti-settling agent, 1-5 parts by volume of a dispersant, and 1-5 parts by volume of a curing agent. The slurry ink disclosed by the invention has high temperature resistance and high calendering tensile property, and can be subjected to high-temperature hot-pressing secondary forming after printing curing, and the surface of the slurry ink does not crack and fall off after high-temperature hot-pressing secondary forming. Meanwhile, the prepared ink is good in stability in a normal-temperature state and long in storage period.

Description

technical field [0001] The invention relates to the technical field of electroplating ink, in particular to a single-component low-temperature curing imitation electroplating ink and a preparation method thereof. Background technique [0002] At present, the manufacturing process of the colorful effect of the mobile phone cover plate is relatively complicated. During the manufacturing process, because the surface is brittle after electroplating and cannot be hot-pressed, it is necessary to cut a large piece of PC or PMMA cover plate and perform hot-press forming. Afterwards, mirror effect electroplating can be carried out. With the increasing demand for colorful and high-gloss metal mirror effects for 5G mobile phones, back covers made of PC / PMMA materials that can be formed at low cost by thermocompression and have better heat dissipation than glass are being widely used. [0003] Existing mirror-surface silver paste inks prepared by using ultra-thin electroplating aluminu...
