Multifunctional filter screen material for air conditioner internal unit and preparation method of material

Abstract

The invention discloses a multifunctional filter screen material for an air conditioner internal unit. The multifunctional filter screen material comprises, by weight, 4-6 parts of heat conduction additives, 10-15 parts of nano-titanium dioxide aqueous dispersion with the concentration of 40%, 50-60 parts of epoxy resins, 1-5 parts of poly 1, 4-diphenyl diacetylene, 8-14 parts of processing agents, 6-9 parts of natural bactericidal extracts and 30-40 parts of activated carbon fibers. The multifunctional filter screen material has filtering function and further has the functions of restraining and sterilizing bacteria and removing formaldehyde, PM2.5 (particulate matter2.5) filtering effect of the material is good, formaldehyde removing rate is high, bacterium restraining and sterilizing kinds are wide, service life is long, heat-conducting property is good, and the material is safe and environmentally friendly. The invention further provides a preparation method of the material. The method is low in material cost and simple in process, raw materials are easily acquired, and the filter screen material serving as the air conditioner internal unit has high practical values and good application prospect.

Description

technical field [0001] The invention relates to the technical field of air-conditioning materials, in particular to a multifunctional filter material for an air-conditioning inner unit and a preparation method thereof. Background technique [0002] With the development of the economy, people have more and more requirements for the functions of air conditioners. Air conditioner filters are mainly used for pre-filtration of air-conditioning internal units and ventilation systems, purification of air-conditioning clean room return air filtration, pre-filtration of high-efficiency filtration, and air compressors. pre-filtering. As the environment changes, indoor air pollution is becoming more and more serious. It not only contains some harmful gases and fine particles such as formaldehyde and toluene, but also contains a large number of bacteria and fungi, such as Neisseria meningitidis, Mycobacterium tuberculosis and Escherichia coli. , Staphylococcus aureus, etc., these bacte...

Problems solved by technology

High-quality activated carbon has a large specific surface area (up to 3000 square meters per gram), is a non-polar adsorbent, and has strong hydrophobicity, so activated carbon has good adsorption properties for non-polar substances such as benzene, but for polar The adsorption of formaldehyde is very poor, so activated carbon cannot effectively remove formaldehyde in the air by adsorption.

In addition, due to air purification only by adsorption, there are disadvantages of adsorption saturation and easy re-release as environmental conditions change.

Since the utilization efficiency of visible light of photocatalyst is very low at present, activated carbon loaded with photocatalyst needs to provide ultraviolet light source device, which increases the complexity and cost of the device on the one hand, and on the other hand, artificial ultraviolet light source will cause another form of pollution
