Problems solved by technology

At present, the covers of electronic products are mostly plastic or metal. This single style cannot satisfy people's pursuit of fashion and individuality.
Plastic cover and metal cover have many disadvantages. Among them, the homogeneity of plastic cover is serious, and it is easy to fade after long-term use, which affects the appearance of use; although the metal cover is beautiful in appearance, metal has strong interference to the signal and is easy to Defects such as scratches
In order to avoid the interference of metal on the signal, most metal cover products have to adopt a three-stage design, which is complicated and affects its integrity and aesthetics
[0003] With the development of electronic products such as smart phones, the style and material of the product are gradually improved, and the quality of the material is also gradually improved. Among them, the glass cover is favored by a large number of consumers. For the sake of appearance, a layer with Ink of a certain color, when screen printing red ink, because the traditional red ink is made of Fe 2 o 3 It is made of powder plus resin and additives, but Fe 2 o 3 There is a certain absorption in the 5G frequency, which will weaken the 5G signal. Therefore, the use of traditional red ink will affect the strength of the signal

preparation example Construction

[0018] A method for preparing red ink for electronic products, the red ink is composed of the following components by weight percentage: 10-30% silicon hydride particles, 60-80% resin, and 0-10% auxiliary agent.

[0019] Specifically, the red ink of the present invention is used for glass cover plates of electronic products.

[0020] The amount and type of colorant determines the color of the ink. The colorant in traditional red ink is Fe 2 O 3 Powder, Fe 2 O 3 There is a certain absorption at the 5G frequency, which will weaken the 5G signal. Therefore, the use of traditional red ink will affect the signal strength. In order to solve the above problems, the inventors have found through a lot of research that silicon hydride particles prepared under incomplete reaction of silicon and hydrogen are used as a colorant to replace the existing Fe 2 O 3 Powder, after being prepared into red ink, silk-printed on the glass cover of electronic products will not attenuate the signal, and mak...

Embodiment 1

[0038] The preparation method of the silicon hydride particles specifically includes: depositing silicon hydride particles on a flexible substrate by magnetron sputtering, and peeling the silicon hydride particles from the flexible substrate.

[0039] In the silicon hydride particles, based on the total molar amount of silicon atoms and hydrogen atoms, the molar percentage of hydrogen atoms is 3-30%.

[0040] Among them, the process conditions of magnetron sputtering are: the sputtering target is a silicon target, the working gas is argon and hydrogen, the flow rate of argon is 80-120 sccm, the flow rate of hydrogen is 5-15 sccm, and the sputtering power is 10- 12kw.

[0041] The flexible substrate is PET, PEN, PES, PAR or PI.

Embodiment 2

[0043] A method for preparing red ink for electronic products, the red ink is composed of the following components by weight percentage: 20% silicon hydride particles, 75% resin, and 5% additives, wherein the silicon hydride particles adopt the examples Prepared by the preparation method in 1.

[0044] The resin is a polyurethane resin; based on the total weight of the auxiliary agent, the auxiliary agent includes the following components by weight percentage: 55% solvent, 2.5% dispersant, 0.15% defoamer, 0.25% flow A leveling agent, 0.15% anti-settling agent, wherein the solvent is an alcohol solvent, the dispersing agent is a polyester hyperdispersant, and the defoaming agent is a silicone-free foam-breaking polymer solution. The leveling agent is polyether modified polydimethylsiloxane, and the anti-settling agent is polyamide wax.

[0045] The preparation method is as follows: the silicon hydride particles, resin and auxiliary agent are mixed in proportions, stirred uniformly,...

Abstract

The invention discloses red printing ink used for an electronic product and a preparation method thereof. The red printing ink contains silicon hydride particles. The silicon hydride particles are prepared by adopting magnetron sputtering or arc discharge, wherein mole percent of hydrogen atoms is controlled to be 3-30% when the silicon hydride particles are prepared. The red printing ink disclosed by the invention has the advantages that the silicon hydride particles with the hydrogen atom mole percent of 3-30% are used for preparing the red printing ink, the traditional red printing ink madefrom Fe2O3 powder is replaced, the problem of signal attenuation is solved and red is purer.

Description

Technical field [0001] The invention relates to the technical field of inks, in particular to a red ink for electronic products and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, electronic products such as mobile phones, tablet computers, cameras, and notebook computers have gradually become popular. At this stage, the cover plates of electronic products are mostly plastic or metal. This single style cannot satisfy people's pursuit of fashion and individuality. Plastic cover plates and metal cover plates have many shortcomings. Among them, the homogeneity of plastic cover plates is serious, and it is easy to fade after long-term use, which affects the aesthetics of use. Although metal cover plates are beautiful in appearance, metal has strong interference with signals and is easy to Shortcomings such as scratches. In order to avoid metal interference to the signal, most metal cover products have to adop...
