Problems solved by technology

The wind wheel is installed inside the air duct of the air conditioner. During use, dust and microorganisms in the air are easy to adhere, multiply and deposit on its surface. Since the wind wheel is difficult to disassemble and clean, it will affect the air volume, noise and energy efficiency after long-term use , and after stopping and restarting, the dust and microorganisms on the surface may fall off, which will produce peculiar smell and form secondary pollution, thus affecting air quality

Embodiment 1

[0068] In this embodiment, the centrifugal wind wheel material of the air conditioner is prepared, and the specific formula is shown in Table 1.

[0069] Table 1. Raw materials and proportions of centrifugal wind wheel materials (mass fraction unit: %)

[0070]

[0071] The raw materials (except glass fiber) according to the above ratio are mixed and stirred evenly and then added to the hopper of the extruder, while the pretreated glass fiber is introduced from the opening of the barrel of the extruder separately, and all components are heated, Shearing, mixing, plasticizing into a uniform melt, cooling and pelletizing after passing through the die, to obtain the required air-conditioning centrifugal fan material. Wherein, the temperature range of each section of the extruder is 190-230° C., and the screw speed is 120-140 r / min.

Embodiment 2

[0077] In this example, with reference to GBT 17037.1-1997, the centrifugal wind wheel materials prepared in Example 1, Comparative Example 1 and Comparative Example 2 were injection molded, and the obtained samples were subjected to mechanical performance tests, antibacterial and antifungal tests, surface Performance testing and accelerated testing against dust accumulation.

[0078] Specifically, the mechanical performance test includes tensile, bending and impact tests, wherein the tensile performance is carried out according to GB / T1040.2-2006, the bending performance is carried out according to GB / T 934-2008, and the impact performance is carried out according to GB / T 1843-2008 . The antibacterial test and mildew test are carried out according to GB 21551.2-2010, and the antibacterial rate is tested according to the film method. The surface performance test is carried out by measuring the contact angle between the surface of the material and water. Anti-dust acceleratio...

Embodiment 3

[0088] In this example, a cross-flow wind impeller material for an air conditioner is prepared. The specific formula is shown in Table 4.

[0089] Table 4. Raw materials and proportions of cross-flow wind wheel materials (mass fraction unit: %)

[0090]

[0091] The raw materials (except glass fiber) according to the above ratio are mixed and stirred evenly and then added to the extruder hopper. The pretreated glass fiber is introduced from the opening of the extruder barrel separately, and all components are heated and sheared by the extruder Cutting and mixing, plasticizing into a uniform melt, cooling and pelletizing after passing through the die, to obtain the required air-conditioning cross-flow wind wheel material. Wherein, the temperature range of each section of the extruder is 210-250°C.

Abstract

The invention provides an air conditioner wind wheel material as well as a preparation method and application thereof. The air conditioner wind wheel material comprises an antibacterial agent and a fluorine-containing surface modifier. According to the air conditioner wind wheel material provided by the invention, the fluorine-containing surface modifier can reduce the surface energy of an air conditioner wind wheel, so that the attachment force of dust and microorganisms to the surface of the air conditioner wind wheel can be reduced; meanwhile, the antibacterial agent can also inhibit and kill attached microorganisms in time to further synergistically and effectively prevent attachment and increase of the dust and the microorganisms on the surface of the air conditioner wind wheel, so that the accumulation amount of the microorganisms and the dust on the surface of the wind wheel is reduced.

Description

technical field [0001] The invention relates to the field of air-conditioning materials, in particular, the invention relates to an air-conditioning wind wheel material and a preparation method and application thereof. More specifically, it relates to an air conditioner wind wheel material, a method for preparing the air conditioner wind wheel material, an air conditioner wind wheel and an air conditioner. Background technique [0002] At present, the internal unit of the air conditioner often adopts a cross-flow wind wheel or a centrifugal wind wheel, and the materials used are mostly resin-based materials reinforced with glass fibers. The wind wheel is installed inside the air duct of the air conditioner. During use, dust and microorganisms in the air are easy to adhere, multiply and deposit on its surface. Since the wind wheel is difficult to disassemble and clean, it will affect the air volume, noise and energy efficiency after long-term use , and after it is stopped an...
