preparation example Construction

[0035] On the other hand, an embodiment of the present invention provides a method for preparing the above-mentioned anti-condensation material, including:

[0036] The hydrophilic polymer material and the porogen are dissolved in a solvent to prepare a film casting liquid, the film is laid, and the porogen is removed to obtain the anti-condensation material.

[0037] The embodiment of the present invention provides a method for preparing an anti-condensation material. The anti-condensation material is prepared by casting a film method. The obtained anti-condensation material is in the form of a membrane. The condensation material is pasted on the surface of the condensation occurrence site. Since the anti-condensation material is a porous film made of hydrophilic polymer material, the anti-condensation material has good water absorption and hydrophilic properties, and can replace the flocking cloth to absorb moisture in the air. Avoid the formation of condensation, so as to ...

Embodiment 1

[0056] Dissolve the sulfonated polyethersulfone resin in N-methylpyrrolidone at a mass fraction of 10%, stir to obtain a transparent solution of sulfonated polyethersulfone, and dissolve a certain amount of β-cyclodextrin in a mass fraction of 95% % ethanol in aqueous solution, to obtain a β-cyclodextrin ethanol solution with a mass fraction of 60%, drop the β-cyclodextrin ethanol solution into the transparent solution of sulfonated polyethersulfone, and stir at room temperature for 12 hours Obtain a casting solution, wherein the mass ratio of the β-cyclodextrin to the sulfonated polyethersulfone resin is 50:100000;

[0057] Filter the casting solution and cast it on a horizontal glass surface, bake it in an oven at 60°C for 72 hours to obtain a flat film;

[0058] Continue to place the obtained flat film in a vacuum oven at 80°C to dry for 1 hour, then reflux the dried flat film in 95% methanol aqueous solution for 30 min, remove the β-cyclodextrin in the flat film, and fix ...

Embodiment 2

[0060] Dissolve the sulfonated polyethersulfone resin in N,N-dimethylacetamide at a mass fraction of 10%, stir to obtain a transparent solution of sulfonated polyethersulfone, and dissolve a certain amount of β-cyclodextrin in In an aqueous solution of ethanol with a mass fraction of 95%, an ethanol solution of β-cyclodextrin with a mass fraction of 60% is obtained, and the ethanol solution of β-cyclodextrin is added dropwise into the transparent solution of sulfonated polyethersulfone, at room temperature The casting solution was obtained after stirring for 10 hours, wherein the mass ratio of the β-cyclodextrin to the sulfonated polyethersulfone resin was 1:100000;

[0061] Filter the casting solution and cast it on a horizontal glass surface, bake it in an oven at 50°C for 48 hours to obtain a flat film;

[0062] Continue to place the obtained flat film in a vacuum oven at 80°C to dry for 3 hours, and then reflux the dried flat film in 95% methanol aqueous solution for 20 mi...

Abstract

The invention relates to the technical field of anti-condensation and in particular to an anti-condensation material as well as a preparation method and application thereof. The anti-condensation material can be prepared as a matte plastic film, is attractive in appearance, is capable of replacing flocked cloth to adsorb condensate and is capable of increasing the volatilization speed of the condensate, the purpose of repeated use is achieved, condensate blowing out is reduced, problems of bacterial propagation caused by humidity increase and the like are avoided, and the user experience is improved. The anti-condensation material provided by the embodiment of the invention is a porous material made of a hydrophilic high polymer material. The embodiment of the invention is applied to air-conditioner condensate prevention.

Description

technical field [0001] The invention relates to the field of anti-condensation technology, in particular to an anti-condensation material and its preparation method and application. Background technique [0002] During the cooling process of the air conditioner, when the internal air duct, cross-flow blade, electric heater and other parts of the indoor unit of the air conditioner, the edge of the air outlet and the air guide vane of the indoor unit of the air conditioner encounter hot air with high indoor humidity, the Condensation of water droplets occurs on the surface, forming condensation. [0003] During the use of the air conditioner, condensation is blown out from the air outlet of the indoor unit of the air conditioner, which will affect the user experience, and even as the humidity increases, it is easy to breed bacteria, which is not conducive to human health. [0004] At present, in order to reduce the adverse effects of condensation, flocking cloth is usually at...
