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, a preparation method and application thereof. The coating includes A component and B component; A component includes fluorocarbon resin, propylene glycol methyl ether acetate, butyl acetate, ethylene glycol butyl ether, polyketone resin, hydroxyl acrylic resin, dispersant, defoamer, fluid Leveling agent, curing accelerator, white paste, black paste, anti-settling agent; B component includes curing agent, butyl acetate, xylene. The anti-condensation coating matrix resin of the present invention selects fluorocarbon resin with low surface energy, the low surface energy reduces the adhesion between the surface and water droplets, has good hydrophobicity, and can play a good hydrophobic effect; for ring network cabinets It has the characteristics of a variety of substrates. By adding an appropriate amount of polyketone resin and hydroxyacrylic acid, the coating has good adhesion to plastics, glass and metal, and is suitable for ring network cabinets with various substrates.

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, but in actual operation, condensation is common inside outdoor cabinets, causing metal parts to corrode. In severe cases, the condensed water directly drips on the surface of the equipment or forms condensation on the surface of the equipment, which gradually damages the internal components and causes component failures. At the same time, due to the reduction of the insulating 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 characteristics of the cabinet make the moisture...
