Abstract

The invention provides LDS (Laser Direct Structuring) coating capable of being activated by laser. The LDS coating is prepared from the following components in parts by weight: 50 to 70 parts of resin, 5 to 10 parts of LDS laser powder, 5 to 60 parts of a solvent, 10 to 30 parts of a curing agent, 2 to 10 parts of a curing accelerant, 0.5 to 2 parts of a dispersant, 0.3 to 1.5 parts of a de-foaming agent, 0 to 40 parts of filler and 0 to 1.5 parts of a flatting agent, wherein the LDS laser powder is a metal organic compound; the LDS laser powder comprises an organic matter outer layer and a metal inner layer; the organic matter outer layer is gasified under laser irradiation; the curing accelerant is a mixture of dimethylimidazole and cobalt naphthenate. According to the LDS coating provided by the invention, the dimethylimidazole and the cobalt naphthenate are used as the curing accelerant and the LDS coating can be cured within half an hour at room temperature. The LDS coating provided by the invention is applied to an antenna and the prepared antenna has a strong signal receiving capability and low production cost.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a laser-activatable LDS coating and its preparation method and application. Background technique [0002] Due to the vigorous development of information technology, the advancement of wireless communication technology has been driven, and mobile communication devices have become an essential communication tool for modern people. Therefore, the demand for mobile phone functions is also increasing day by day. Since the radio wave of wireless communication must be frequency-upped and carried by the carrier, it can be effectively multiplexed and transmitted, and these actions must be carried out with the help of an antenna, so the antenna is a very important component in the wireless communication device. [0003] Antennas are usually composed of radio frequency components and their substrate fixing brackets. The radio frequency component is a metal piece of a certain shape or a f...
