Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with specific embodiments.

[0017] The ink of the present invention includes the following components: polystyrene-polyisoprene-polystyrene (SIS, PS 22% by weight); silver trifluoroacetate (98%, AgTFA); butanone (≥99.0% ); Dimethylacetamide (≥99.5% DMAc).

[0018] In addition, formaldehyde solution (36.5-38% aqueous solution) and sodium hydroxide (≥97%) are required.

[0019] The preparation steps of the above ink are as follows:

[0020] 1. Under normal temperature and pressure, add 10 ml of methyl ethyl ketone and 10 grams of silver trifluoroacetate (AgTFA) to the methyl ethyl ketone, shake to make it fully dissolved;

[0021] 2. Add 200 mg of polystyrene-polyisoprene-polystyrene (SIS), shake to fully dissolve it to form a transparent ink;

[0022] 3. In order to adjust the viscosity of the ink, add dimethylacetamide (DMAc) in an appropriate amount, which can improve the fluidity of the ink and prev...

Abstract

The invention aims at providing particle-free printing electronic ink which is smooth in ink jet, low in cost, simple in preparation, and suitable for the full-printing electronic printed FPC as wellas a preparation method of the ink. The ink is prepared from the following components: polystyrene-polyisoprene-polystyrene (SIS, PS, 22 percent); silver trifluoroacetate (98 percent, AgTFA); and butanone (greater than or equal to 99 percent). The preparation method of the ink comprises the following steps: (1) adding 10ml of butanone into a reactor at normal temperature and normal pressure, adding 10g of silver trifluoroacetate into the butanone, oscillating, and sufficiently dissolving the silver trifluoroacetate; and (2) adding 200mg of polystyrene-polyisoprene-polystyrene, oscillating, sufficiently dissolving the polystyrene-polyisoprene-polystyrene, and forming transparent ink. The particle-free printing electronic ink and the preparation method thereof can be applied to the field ofprinted materials.

Description

Technical field [0001] The invention relates to the field of printed materials, in particular to a particle-free printing electronic ink and a preparation method thereof. Background technique [0002] Fully printed additive printing electronics is a brand-new FPC manufacturing technology. The FPC circuit is printed on the substrate by printing or inkjet printing, and the FPC is formed after the circuit is cured. This technology requires the use of suitable printing ink, and the ink must be able to adapt to the inkjet requirements of the printer to complete the FPC printing job. But most of the time, the ink used will have metal conductors, which increases the risk of nozzle clogging, and the manufacturing process is complicated and the manufacturing cost is high. Summary of the invention [0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a particle-free printing electronic ink that is smooth, low in co...
