Abstract

The invention discloses an antenna silver paste and a preparation method thereof, an antenna for electronic equipment and electronic equipment. The antenna silver paste comprises 6-10 parts by weightof resin, 10-20 parts by weight of a diluent, 1-3 parts by weight of a curing agent, 1-2 parts by weight of a coupling agent, 0.5-1 part by weight of a dispersant, 1-2 parts by weight of a defoamer, 0.5-1 part by weight of a leveling agent, 1-2 parts by weight of a thickener and 60-80 parts by weight of conductive silver powder, wherein the dielectric constant of the resin is less than 2, the weight average molecular weight of the resin is 15,000-50000, and the curing temperature of the curing agent is not greater than 80 degrees. Therefore, the antenna silver paste can be cured at a low temperature of 80 degrees, and the antenna silver paste has good reliability, adhesion, conductivity, and chemical resistance after curing so as to enhance the signal of the electronic equipment applying the antenna silver paste and improve the use performance of the electronic equipment and enhance the user experience.

Description

technical field [0001] The present application relates to the technical field of conductive ink, in particular, to an antenna silver paste and a preparation method, an antenna for an electronic device, and an electronic device. Background technique [0002] With the advent of the 5G era, the requirements for mobile phone signals are getting higher and higher. At present, the back cover of the mobile phone is usually made of glass to enhance the signal of the mobile phone. In order to make the back cover of the mobile phone have a gorgeous appearance, a decorative film is usually attached to the inside of the glass case, and the antenna silver paste is printed on the decorative film. The antenna silver paste has a significant effect on the enhancement of the mobile phone signal, so as to significantly enhance Mobile phone signal. [0003] However, the current antenna silver paste and its preparation method, the antenna for electronic equipment, and the electronic equipment ...
