Definitions
- the present invention relates to a prefilter used for an air conditioner such as an air conditioner or an air purifier.
- Pre-filters that have net power are provided at the air suction locations of air conditioners such as air conditioners and air purifiers so that dust and dirt in the air are not taken into the air conditioner. Yes.
- This prefilter is usually composed of a synthetic resin net and a support frame.
- Indoor dust and dirt include insoluble dust such as cotton dust, sand dust, mud and cigarette smoke, water-soluble dirt such as cigarette char, oil-soluble dirt such as oil smoke and soot.
- insoluble dust such as cotton dust, sand dust, mud and cigarette smoke
- water-soluble dirt such as cigarette char
- oil-soluble dirt such as oil smoke and soot.
- the pre-filter captures what does not pass through the hole due to the size of the mesh (mesh), but there are fine dirt (such as cigarette smoke, soot and dust) in the air.
- the net is charged and captured electrically.
- the outer surface of the fiber constituting the net is coated with fluorine resin having a high chargeability, and it is described that it can be washed with water (Japanese Patent Laid-Open No. 08-22). 4413, JP 08-224414).
- Japanese Patent Laid-Open No. 2006-122871 proposes coating with fluorine resin using a noinder or the like to prevent adhesion of oil-containing dust! RU
- fluorine resin does not adhere well to other synthetic resins. Simply attaching fluorine resin does not cause frequent detachment, brushing or wiping, and peeling. There is a problem with durability.
- the subject of the present invention is a coating film of a specific fluorine-containing polymer which is rich in durability on the surface of the mesh and excellent in decontamination even if it is a prefilter made of the same material as a conventional prefilter.

Adheres to the side and adheres to dust. The same oily soil adheres to the dust side of the prefilter surface and adheres to the dust because of the oil repellency of the prefilter surface.
- the water / oil repellency of the coating refers to the property that both the water contact angle and the oil contact angle of the coating surface are high.
- a film having a water contact angle of 80 degrees or more and an oil contact angle of 35 degrees or more means that both water-soluble dirt and oil-soluble dirt have an affinity for the film. Poor (without adhering to the coating), therefore point power absorbed by cotton dust and sand dust is preferable. The method for measuring the water contact angle and the oil contact angle will be described later.

It is easy to wash with water and can be easily removed regardless of oily water, and it has excellent strength and adhesion to the net. It is durable enough to withstand use.
- the synthetic resin which has been difficult to surface-treat with fluorine resin, has been described as a prefilter net material.
- the coating composition used in the present invention is, of course, a metal. It can also be applied to heat-resistant prefilters such as glass fiber and ceramic fiber.
- Metals and ceramics that make up the pre-filter mesh include stainless steel (SUS304, SUS31 6, SUS316L, SUS430, SUS310S, etc.), nickel, monel, brass, red copper, phosphor bronze, copper, iron, zinc-drawn iron wire
- metal fibers such as steel, aluminum, titanium, nichrome, hastelloy, and inconel
- ceramics such as acid aluminum, acid zirconium, my strength, silicon nitride, glass, PZT, graphite, and carbon fiber.
- ZEFLEL GK-510 Hydrooxyl value 60mgKOH, g, Acid value 9mgKOH, g, Number average molecular weight 12000, Fluorine content 36% by mass, 100 parts by weight of refractive index 1.4, butyl acetate solution, solid content 50% by weight, and amino group-containing silicone oil (NUC SILICON E FZ3705 (trade name) as antifouling component (B).
- DBTDL dibutyltin dilaurate
- Mass parts and 30 parts by mass of propylene glycol monobutyl ether acetate were blended to prepare a coating composition having a solid concentration of 20% by mass.
- This paint composition is spray-coated on the next prefilter by a conventional method, and after applying compressed air to the filter to eliminate clogging, it is baked at 100 ° C for 10 minutes, dried and cured. A fluororesin film was formed on the surface of the film to prepare Prefilter 1 of the present invention.
- Support frame Made of polypropylene
- Mesh opening vertical 50 mesh, horizontal 35 mesh
- the water contact angle and the oil contact angle of the prefilter 1 and the base material (PET) of the prefilter before forming the coating were examined. Since the contact angle of the pre-filter itself cannot be measured, the contact angle between the PET sheet on which the fluororesin film was formed and the PET sheet before the film formation was measured in the same manner as described above. As a result, the water contact angle of the PET sheet (corresponding to prefilter 1) on which the fluorine resin film was formed was 103 degrees, and the oil contact angle was 50 degrees. The PET sheet (corresponding to the prefilter for comparison) before film formation had a contact angle with water of 80 degrees, and the contact angle with oil was 15 degrees.
- Bending the prefilter 180 degrees and then bending it 180 degrees in the opposite direction is one cycle and repeated 10 cycles. Then, the bent part is visually observed to visually check for the presence or absence of sag.
- the pre-filter 1 and the pre-filter (comparative pre-filter) before forming the coating are each attached to an air conditioner installed on the upper part of the wall of a smoking room having a floor area of about 15 m 2 .
- the evaluation is performed by visually checking the dirt state before and after wiping.
- the tobacco dirt was removed to the same extent as when it was attached, and the dirt became almost unaltered. Dirt was hardly removed.
- a coating film containing a fluorine-containing polymer having excellent adhesion to a synthetic resin can form a film on the surface of the net, and the prefilter surface is rubbed.
