Air conditioner filter core capable of releasing negative ions and production method thereof

Abstract

The invention belongs to the technical field of air-conditioner parts, and relates to an air conditioner filter core capable of releasing negative ions and a production method thereof. The air conditioner filter core includes an air-conditioning filter core skeleton and a filter layer comprising a matrix material and an anion additive. The air conditioner filter core has the advantages of neutralizing and decomposing harmful gases such as formaldehyde, benzene and TVOC, avoiding the problem of adsorption saturation of the conventional adsorption materials, improving the concentration of air negative ions, and improving the air environment; has a good function of capturing PM2.5 and PM10 particles in the space, blocking odor, antibacterial and antibacterial, and is simple to produce and lowin cost.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning accessories, and relates to an air-conditioning filter element capable of releasing negative ions and a preparation method thereof. Background technique [0002] The air conditioner filter element is used to filter the air circulation in the space (inside the compartment) and inside and outside the space (inside and outside the compartment). Generally, the filter paper of a high-quality air conditioner filter element adopts a sandwich structure of polymer fibers, which can effectively filter tiny particles, pollen, bacteria, dust, industrial Exhaust gas and various odors, high-efficiency filtration and adsorption of particulate impurities to achieve air purification performance. Or the activated carbon composite filter cloth with high-efficiency adsorption material activated carbon and filament non-woven fabric is combined, which has a compact structure and can well absorb TVOC, benzene, ...

Problems solved by technology

Their advantages and disadvantages are: 1. Advantages of white filament material: large air volume, fuel-efficient (when applied to cars), long-term use is not easy to breed bacteria and does not produce peculiar smell. Disadvantages: single-effect filter, unable to filter fine dust particles, long-term Use will cause dust to accumulate in the cabin and air-conditioning ducts; 2. Advantages of double-sided filament carbon fiber material: light material, large air volume, affordable price, and can filter the finest dust particles. Disadvantages of double-sided filament carbon fiber material: single-effect filter , Because it is a three-layer sandwich design, it is easy to breed bacteria when used in a humid environment for a long time; 3. The advantages of high air volume electrostatic grid material: large air volume, fuel saving, and effectively improve the air quality in the car. Disadvantages of high air volume electrostatic grid material: long-term Part of the effect is lost in the absence of light; 4. Advantages of pure imported activated carbon material: double-effect filtration, moisture-proof, and odor removal; disadvantages of pure imported activated carbon material: relatively small air volume and expensive price; 5. Advantages of ordinary activated carbon material: double-effect filter, Moisture-proof, odor-removing, disadvantages: the carbon layer is very thin and there are many pieces, and the cost performance is slightly lower; 6. Advantages of reinforced yellow filament material: large air volume, fuel-saving, long service life, disadvantages of reinforced yellow filament material: more expensive, single-effect filter

[0009] Although the above scheme can effectively filter PM2.5, toluene, butane and other pollutants into the car and provide the occupants with a healthy car environment, it cannot release negative ions and cannot effectively increase the concentration of negative ions in the air in the car, and its HEPA is used as the filter layer, and the small pore size of HEPA will limit the gas flow to a certain extent
