Abstract

The invention discloses a corrosion-resistant electronic element coating. The corrosion-resistant electronic element coating consists of the following components in parts by weight: epoxy resin 50-70 parts, graphite powder 3-5 parts, aluminium powder 80-85 parts, zinc powder 2-4 parts, nickel powder 1-3 parts, tin oxide 6-12 parts, sodium tripolyphosphate 2-6 parts, acetone 10-18 parts, methylcellulose 1.5-2.5 parts, castor oil polyoxyethylene ether 40-80 parts and sorbic acid 20-30 parts. A stable coating structure is formed, weather fastness, radiation protection ability and anti-static ability are excellent, the structure of the coating is stable in property and can protect an electronic element for a long time, and damage of foreign elements to the electronic element is reduced. The corrosion-resistant electronic element coating is excellent in corrosion resistance, and the metal surface does not have rusty spots even if the corrosion-resistant electronic element coating soaks in sodium chloride for 300-400 hours due to the fact that the corrosion resistance of the corrosion-resistant electronic element coating is improved to a certain degree by sorbic acid.

Description

technical field [0001] The invention relates to the field of metal coatings, in particular to a corrosion-resistant electronic component coating. Background technique [0002] Electronic components are important parts that constitute electronic equipment or electromechanical equipment. They are relatively small and scattered, and are easily affected by environmental factors, resulting in oxidation, deformation or other damage, which affects the functions of electronic components and even brings damage to the entire equipment. come to harm. Factors from the environment, including air, temperature and humidity, radiation, etc., will cause damage to electronic components, so reducing the impact of environmental factors on electronic equipment is very important. Most of the existing protection methods are structurally improved, or different materials are selected, but the effect is still limited, and the cost is high, and the cost performance is low. Therefore, people came up ...
