Abstract

The invention provides a hydrophobic coating and an air conditioner water pan comprising the same. The technical problem that an existing air conditioner water pan cannot achieve self cleaning and mildew prevention can be solved. The hydrophobic coating comprises, by mass percent, 1-30 of hydrophobic particles and 70-99 of pure metal or alloy, the hydrophobic particles are selected from graphite, silicone powder, hydrophobic silicon dioxide, polytetrafluoroethylene, graphite fluoride and at least one kind of graphite, silicone powder, hydrophobic silicon dioxide, polytetrafluoroethylene and graphite fluoride treated by a cationic surface active agent, and the pure metal or alloy is selected from at least one of Ni, Cu and Co. The hydrophobic coating can be applied to hydrophobic coating preparation of the air conditioner water pan, and the self-cleaning capability of the coating can be greatly improved on the basis of ensuring the basic performance of the coating.

Description

technical field [0001] The invention relates to a hydrophobic coating, in particular to a hydrophobic coating capable of realizing the dual functions of self-cleaning, antibacterial and anti-mildew, and an air conditioner water tray containing the coating. Background technique [0002] In the air conditioner assembly, the water pan is used to receive the condensed water falling from the heat exchanger and discharge the condensed water out of the air conditioner. The water tray currently used in the industry cannot discharge the condensed water out of the air conditioner in time, which can easily cause the accumulation of dust, leading to the enrichment of microorganisms, which in turn affects the quality of the living environment and damages human health. If the water tray of the air conditioner can have a self-cleaning function, the problems of dust accumulation and microbial enrichment can be solved, and the living environment can also be guaranteed.
