Mildew-resistant coating for circuit board in charger

Abstract

The invention provides a mildew-resistant coating for a circuit board in a charger. The mildew-resistant coating comprises the following raw materials by weight: 14-16 parts of chlorine dioxide, 11-13parts of tannic acid, 6-8 parts of ketoconazole, 10-12 parts of diatomite, 9-11 parts of methyl benzimidazole carbamate, 30-50 parts of sorbic acid, 12-16 parts of boric acid, 11-13 parts of an adsorbent, 18-22 parts of sodium pentachlorophenate, 3-7 parts of ammonium polyphosphate, 18-24 parts of calcium propionate, 8-14 parts of gelatin, 9-11 parts of sodium chlorite, 1-3 parts of stearic acidand 50-60 parts of water. The mildew-resistant coating provided by the invention has the following beneficial effects: (1) the mildew-resistant coating has small irritation, excellent anti-mildew performance, a wide application range, good effect, long duration and low cost, and can effectively absorb moisture in humid air and prevent the circuit board in the charger from mildew; and (2) the coating is applicable to a wide range of pH value and is convenient to use and operate.

Description

technical field [0001] The invention relates to the field of charging piles, in particular to an anti-mildew coating for circuit boards in chargers. Background technique [0002] Charging piles are now more and more widely used. The function of charging piles is similar to that of fuel dispensers in gas stations. They can be fixed on the ground or walls, and installed in public buildings (public buildings, shopping malls, public parking lots, etc.) and parking lots in residential areas. Or in the charging station, various types of electric vehicles can be charged according to different voltage levels. The input end of the charging pile is directly connected to the AC grid, and the output end is equipped with a charging plug for charging the electric vehicle. Charging piles generally provide two charging methods: conventional charging and fast charging. People can use a specific charging card to swipe the card on the human-computer interaction interface provided by the charg...

Problems solved by technology

[0003] Since the charging piles are generally installed outdoors, exposed to the sun and rain for a long time, especially in humid environments such as the south, the circuit boards in the charging machine will become mildewed for a long time, affecting the normal operation of the line and eventually affecting the use of the charging pile.
