Embodiment 1

[0041] Adjust the mixed solution of ethanol and water to a pH of 2-2.5 and a temperature of 50°C, slowly add a silane coupling agent dropwise to the mixed solution of ethanol and water, stir until the silane coupling agent is completely hydrolyzed, and add Add silicon dioxide nanoparticles, keep stirring until the surface of the silicon dioxide nanoparticles is activated, centrifuge, wash, and dry to obtain modified silicon dioxide nanoparticles.

[0042] Add 5%wt of the above-mentioned modified silica nanoparticles, 94%wt acrylic acid, and 1%wt initiator to a mixed solvent of ethanol and water 1:4 and disperse evenly to prepare a coating. Put the water receiving tray in an oven at 60°C Pre-treat for 30 minutes, then spray the paint evenly on the surface of the plastic parts, and put the sprayed plastic parts in a blast oven at 60°C for 1 hour to obtain a surface self-cleaning water tray.

Embodiment 2

[0044] The preparation method of modified silica nanoparticles is the same as that in Example 1.

[0045] Add polyvinylidene fluoride particles into 10% ethanol dimethylformamide solvent, heat and fully dissolve to obtain a polyvinylidene fluoride solution, add 20% mass fraction of modified silica nanoparticles to the polyvinylidene fluoride Ethylene solution, mixed evenly to obtain a spray solution. Pretreat the water tray in an oven at 60°C for 30 minutes, then spray the paint evenly on the surface of the plastic parts, and bake the sprayed plastic parts in a blast oven at 60°C for 1 hour to obtain a surface self-cleaning water tray.

Abstract

The invention discloses a water pan and an air conditioner, and belongs to the technical field of air conditioner water pan materials. A coating is arranged on the surface of the water pan, and raw materials of the coating comprise a high polymer material and an inorganic hydrophobic material. The mass ratio of the high polymer material is 90%-99.5%, and the mass ratio of the inorganic hydrophobic material is 0.5%-10%; wherein the high polymer material comprises at least one of polyurethane, polyvinylidene fluoride, polytetrafluoroethylene, siloxane and a polymer thereof, fluorosilane and a polymer thereof, titanate, saturated fat, unsaturated polyester, amino resin and fluorosilicone modified resin; the inorganic hydrophobic material comprises metal oxide semiconductor particles or non-metal oxide semiconductor particles. The hydrophobic coating is applied to self-cleaning of the air conditioner, and solves the problem that when an existing hydrophobic coating is used for the coating of the water pan of the air conditioner, so that the cleaning of the water pan cannot be well achieved, and the coating has the advantages of being good in hydrophobicity and high in self-cleaning capacity, and the original structure and materials do not need to be changed.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning water tray materials, and in particular relates to a water tray and an air conditioner. Background technique [0002] In the air conditioner assembly, the water receiving tray is used to receive the condensed water dropped by the heat exchanger and drain the condensed water out of the air conditioner. Due to the material properties and structural design of the existing air-conditioning water tray, the problem of dust accumulation is serious. If the water tray cannot discharge the condensed water out of the air conditioner in time, it will easily cause the accumulation of dust, and lead to the enrichment of microorganisms, which is prone to mildew. Affect the quality of living environment and damage human health. However, in the current air-conditioning industry, most of the air-conditioning cleaning solutions are double-cleaning technology solutions for the air-conditioning evaporator an...
