Description

technical field [0001] The invention relates to a water-based epoxy four-proof paint and its preparation method and application. The water-based epoxy four-proof paint can prevent static electricity, salt spray, damp heat and mold, and belongs to the technical field of special functional paint preparation. Background technique [0002] Weapons and equipment are an important part of military deterrence. In order to pursue high range, high precision, and high reliability, a large number of composite materials are used in the structural parts of missiles or aircraft, such as carbon epoxy, high silicon oxygen phenolic, etc., which have low density, low thermal conductivity, High strength and other advantages can meet the needs of light weight and multi-functionality. Compared with metals, composite materials have higher resistivity (volume resistivity is generally greater than 10 10 Ω·cm), it is easy to generate static electricity when it is rubbed, and the accumulation of stat...
