AI Technical Summary

Problems solved by technology

The earliest application of radiant cooling system was in the 1930s, but it has not been widely used due to condensation problems
The preparation process of this kind of scheme is relatively complicated and the cost is high. It is only suitable for the laboratory research stage, and it is difficult to apply to large-scale industrial production.
[0008] 2. Export condensation water
This technology has the following problems: First, the heat exchange coil is not in direct contact with the metal radiant plate, which will inevitably affect the heat transfer, and the actual energy consumption will also increase accordingly; secondly, the complexity of the radiant plate structure increases, Increased production and maintenance costs
The shortcomings of this type of technology are obvious. If the auxiliary equipment is installed on the ceiling, wall or ground together with the radiation terminal, the additional volume, noise, safety, and maintenance difficulties will be difficult to operate in practical applications.

Embodiment 1

[0046] Add a certain amount of polytetrafluoroethylene powder, fluorine-containing wax powder, fluorocarbon resin, methyl silicone oil, organic bentonite and BYK410 anti-sedimentation agent to the mixture of acetone, propylene glycol methyl ether acetate, xylene and cyclohexanone according to the 2; 2; 2; 1 in the mixed solvent, first disperse at high speed for 30 minutes, then use a ball mill to grind the mixture to a white slurry with a fineness of less than 35 microns, as component A. Then mix it with component B (moisture-curing polyurethane 7360) according to a certain proportion, and cure it at room temperature for 15 minutes before construction.

[0047] The composition ratio of the anti-condensation coating in this example is as follows:

[0048]

Embodiment 2

[0050] The anti-condensation coating preparation process of this example is the same as that of Example 1.

[0051] The composition ratio of the anti-condensation coating in this example is as follows:

[0053]

Embodiment 3

[0055] The anti-condensation coating preparation process of this example is the same as that of Example 1.

[0056] The composition ratio of the anti-condensation coating in this example is as follows:

[0057]

[0058] In order to better evaluate the effect of the anti-condensation coating of the present invention, the anti-condensation coating was coated on a tinplate sheet by spraying means to make a sample, and after being fully dried and cured at room temperature, an anti-condensation experiment was carried out. At the same time, the commonly used polyurethane varnish is applied on the tinplate sheet of the same specification as a control model. Place the two samples in a constant temperature and humidity chamber to investigate their anti-condensation performance. Such as figure 1 As shown, under the same conditions (the sample surface temperature is 18±0.2°C, the ambient temperature is 24.1±0.2°C, and the relative humidity is 79%), the dew condensation on the surfac...

Abstract

The invention provides super-hydrophobic anti-moisture condensation paint for a cold radiation tail end and a preparation method thereof. The super-hydrophobic anti-moisture condensation paint is prepared from a component A and a component B, wherein the component A is prepared from hydroxyl acrylic fluorocarbon resin, polytetrafluoroethylene powder, fluorine-containing wax powder, methyl silicone oil, pigment and filler, an auxiliary agent and an organic solvent; the component B is prepared from moisture curing polyurethane. The invention further provides decorative paint containing the anti-moisture condensation paint, and glass, a mirror, the radiation tail end and an air conditioning system, wherein the anti-condensation paint is coated on at least one part of the surfaces of the glass, the mirror, the radiation tail end and the air conditioning system. The super-hydrophobic anti-moisture condensation paint provided by the invention has the advantage of effectively lowering a moisture condensation point or alleviating moisture condensation and also has the advantages of reduction of energy consumption and easiness in construction.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-condensation coating, in particular to a coating that slows down condensation on the surface of a cold radiation plate through superhydrophobicity, or to a coating that reduces condensation of water vapor on the surface of a cold radiation plate Dew point coatings, which can be used in indoor radiant cooling systems. It also relates to a glass, a mirror, a radiation terminal and an air-conditioning system with the anti-condensation coating on the surface. Background technique [0002] Traditional refrigeration and air conditioners are faced with many problems that are difficult to overcome, such as poor thermal comfort, poor indoor air quality, and high energy consumption. The cold radiation cooling system has good thermal comfort, good indoor air quality, low energy consumption, and a wide range of cooling sources. advantage. Nowadays, low-carbon life, energy saving and emissio...
