Abstract

The invention relates to a production method of solvent type ultraviolet photocureable coating capable of shielding Wi-Fi (wireless fidelity) signals. The method is characterized in that the method comprises the steps as follows: (1) putting diphenyl ketone, 3-methyl-3-methoxyacetic acid butyl ester and polyethylene wax slurry into a reaction cylinder for mixing and stirring to form a premixed material, (2) adding 2-hydroxy-3-phenoxy propyl acrylic ester and modified fatty acid epoxy dimethyl acrylate, and further adding four-functional group polyester methyl acrylate and modified fatty group polyurethane methyl acrylate to form a mixture by stirring, (3) adding an acrylic acid flatting agent, a siloxane flatting agent, propylene oxide pentaerythritol tetrapropylene acid ester and vacuum aluminizing pigment, and (4), filtering the mixture acquired in Step (3) and obtaining the solvent type ultraviolet photocureable coating capable of shielding the Wi-Fi signals. The solvent type ultraviolet photocureable coating can shield the Wi-Fi signals effectively, and meet the requirements of the RoHS (Restriction of Hazardous Substances).

Description

technical field [0001] The invention relates to a paint for shielding Wi-Fi signals, in particular to a solvent-based ultraviolet photocurable paint for shielding Wi-Fi signals and a production method thereof. Background technique [0002] With the increasing popularity of electronic consumer goods such as mobile phones, computers, and tablet computers, Wi-Fi has entered people's lives. Wi-Fi is a technology that can connect these electronic devices to each other wirelessly. Wi-Fi has changed our lives and made our lives more and more convenient, allowing us to surf the Internet and transmit data as we like. However, while Wi-Fi brings us convenience, it also brings some disadvantages. For example, in the recent event that the mobile phone Wi-Fi was forced to stop the Shenzhen subway, the Wi-Fi signals emitted by microwave ovens and cameras interfered with the signals of wireless routers, affecting normal work. Therefore, we need to shield Wi-Fi signals in some special eq...
