Embodiment Construction

[0027] Below in conjunction with embodiment the present invention is further described.

[0028] A preparation method of water-based uv conductive silver paste is characterized in that it is composed of the raw materials of the following components by percentage:

[0029] Silver powder: 74%;

[0030] Water-based uv resin: 10%;

[0031] Modified uv resin: 10%;

[0032] Photoinitiator: 5%;

[0033] Storage stabilizer: 0.05%;

[0034] Additives: 0.95%.

[0035] Its preparation method is to mix water-based uv resin, modified uv resin and storage stabilizer, add it to a disperser for dispersing for 5 minutes, then add photoinitiator and disperse at a speed of 800r / min until the photoinitiator is completely dissolved, then add additives and After the silver powder was dispersed for 30 minutes, it was ground with a three-roll machine to a fineness of less than 5 microns to obtain a water-based uv conductive silver paste.

[0036] The present invention can also adopt the followi...

Abstract

The present invention provides a preparation method of aqueous uv conductive silver paste. The aqueous uv conductive silver paste is composed of the following raw materials according to the percentage: 65-75% of silver powder, 10% of aqueous uv resin, 10% of modified uv resin, 5% of photoinitiator, and 0.05% of storage stabilizer and 1-2% of assistant. The preparation method comprises: mixing the aqueous uv resin, the modified uv resin and the storage stabilizer to add into a dispersion machine to disperse for 5 min, adding the photoinitiator into the mixer to disperse at the speed of 800r / min until the photoinitiator is completed dissolved, then adding the assistant and the silver powder to disperse for 30 min, employing a three-roller machine to grind the mixer to allow the fineness to be less than 5 micrometer, and obtaining the aqueous uv conductive silver paste. Through adoption of the aqueous uv scheme, the discharging of VOC is removed, the environmental protection standard is accorded, the uv solidification greatly improves the production efficiency, and good flexibility can product very fine lines for the touch screen silver paste of laser engraving.

Description

technical field [0001] The invention relates to a preparation method of conductive silver paste, in particular to a preparation method of water-based UV conductive silver paste. Background technique [0002] At present, the production of touch screen conductive lines mainly uses baked conductive silver paste. This kind of conductive silver paste has a lot of VOC emissions during the curing process, and the baking temperature reaches 130-160 degrees Celsius. The preparation process has the disadvantages of serious air pollution, environmental protection, and low efficiency. Contents of the invention [0003] In order to solve the above problems, the present invention provides a preparation method of water-based uv conductive silver paste. By using the water-based uv solution, firstly, there is no VOC emission, and the environmental protection standard is complied with. Secondly, uv curing greatly improves the production efficiency. Furthermore, it is good The flexibility ...
