AI Technical Summary

Problems solved by technology

Although the traditional ring network cabinet is installed with a heating and moisture removal device to a certain extent, after this dehumidification method turns the condensation into moisture, the moisture still exists inside the cabinet, and the steam does not discharge out of the cabinet after heating, causing moisture problems. Does not get rid of it at all, and sometimes even makes the dampness worse
In this case, if the outdoor environment temperature drops, the humid air in the cabinet will form condensation again, and the ring network cabinet will be rusted and moldy for a long time.
The heating and dehumidification device will also cause overheating in the box in hot summer weather, resulting in cable damage and aging
Therefore, the use of traditional heating and dehumidification devices has the hidden danger of incomplete dehumidification effect and unsafety
[0005] There are often many kinds of substrates for ring network cabinets, which can be divided into inorganic materials (ceramics, concrete, cement, glass, etc.), organic materials (such as polystyrene plastics, acrylic plates, etc.), metals (cold-rolled steel plates, stainless steel plate, aluminum-zinc-coated plate), etc., so a protective coating can only be applied to ring network cabinets with one or several substrates

Abstract

The invention discloses an anti-condensation coating as well as a preparation method and application thereof. The coating comprises a component A and a component B, the component A comprises fluorocarbon resin, propylene glycol methyl ether acetate, butyl acetate, ethylene glycol butyl ether, polyketone resin, hydroxy acrylic resin, a dispersing agent, a defoaming agent, a flatting agent, a curing accelerator, white paste, black paste and an anti-settling agent; and the component B comprises a curing agent, butyl acetate and xylene. The fluorocarbon resin with low surface energy is selected as matrix resin of the anti-condensation coating, the adhesion between the surface and water drops is reduced due to the low surface energy, good hydrophobicity is achieved, and a good hydrophobic effect can be achieved; and according to the characteristic that the ring main unit has multiple base materials, a proper amount of polyketone resin and hydroxyl acrylic acid are added, so that the coating has good adhesive force to plastic, glass and metal, and the coating is suitable for the ring main unit with multiple base materials.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to an anti-condensation coating and a preparation method and application thereof. Background technique [0002] Metal cabinets for electrical equipment such as control cabinets, substation cabinets, and ring network cabinets are widely used in outdoor environments. However, in actual operation, condensation is common inside outdoor cabinets, causing corrosion of metal parts. In severe cases, the condensed water directly drops on the surface of the equipment or forms condensation on the surface of the equipment. The condensation gradually damages the internal components and causes component failures. At the same time, due to the reduction of the dielectric strength of the insulating material, accidents such as creepage and flashover may be caused in severe cases. [0003] The traditional ring network cabinet has no ventilation measures, and the closed nature of the cabinet prevents...
