Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a moisture-proof coating for power supply equipment and a preparation method thereof. Background technique [0002] In today's society where information is developing rapidly, power supply equipment is an indispensable daily necessities for people. Power supply equipment includes mobile phones, computers, network cards, radios and so on. Coatings for power supply equipment must have excellent electrical conductivity, impact resistance, moisture resistance, flexibility, etc. However, most of the existing coatings for power supply equipment focus on their electrical conductivity, impact resistance and corrosion resistance, etc., but the moisture-proof performance is not high, and there are few developments and productions of moisture-proof coatings applied to power supply equipment. If the power supply equipment is operated in a humid environment for a long time, it ...
