Abstract
Polymer conductive silver paste comprises the following materials including, by weight, 12-17 parts of silver powder, 12-17 parts of copper powder, 12-17 parts of aluminum powder, 1-2 parts of tin powder, 1-5 parts of nickel powder, 3-5 parts of polyester acrylic resin, 6-10 parts of epoxy acrylic resin, 2-4 parts of benzophenone, 2-4 parts of diphenyl diketone, 15-40 parts of trimethylolpropane triacrylate and 10-30 parts of tripropylene glycol diacrylate. According to the polymer conductive silver paste, due to the fact that the silver powder, the copper powder and the aluminum powder are used for replacing silver powder or copper powder in the prior art, the material cost is low; since a moderate amount of the tin powder and the nickel powder are added into the materials, tests show that the gain performance of a wireless receiving antenna can be greatly enhanced, and the direction performance of the wireless receiving antenna can be improved; due to the fact that various chemical compositions which can be cured through UV rays are used as solvents, the polymer conductive silver paste is not only suitable for silk-screen printing but also suitable for printing on a continuous drum-type printing press, manufacturing cost can be greatly lowered, and the polymer conductive silver paste is also suitable for being printed on a flexible substrate.
Description
technical field [0001] The invention relates to a polymer conductive silver paste, a preparation method and its application, in particular to a polymer conductive silver paste suitable for printing on a plastic sheet as a substrate, a preparation method and its application on a receiving antenna . Background technique [0002] Now vehicles are equipped with video or / and audio receiving equipment, so it is inevitable to need a receiving antenna. A high-quality receiving antenna is very important for video or / and audio reception. For the convenience of installation and the need for concealment after installation, the existing audio and video receiving antennas for vehicles are generally printed with a layer of conductive silver paste on a soft substrate, such as a PET sheet, as the receiving terminal. The difference in the composition of the silver paste has a great influence on the receiving effect of the antenna. Common silver paste components suitable for silk screen pri...
