Antibacterial mildew-proof air purification material and preparation method thereof

Abstract

The invention provides an air purification material with antibacterial and mildew-proof functions, the air purification material comprises a filter layer, a transition layer and a functional layer from top to bottom, the filter layer is formed by mixing and stacking different fibers and comprises supporting fibers, strength fibers and superfine fibers, the supporting fibers are polyester fibers with the diameter of 1-2mm and the content of 10-20%, the polyester fibers contain 10-20% of an organic antibacterial agent, and the superfine fibers contain 10-20% of an inorganic antibacterial agent. The strength fibers are made of ABS plastic fibers with the diameter of 0.5-1 mm, the content of the strength fibers is 30-40%, the ABS plastic fibers comprise 5-10% of molecular sieves, 3-10% of zinc oxide and 4-12% of copper oxide, the superfine fibers are polypropylene fibers with the diameter of 0.1-2 microns, the content of the superfine fibers is 40-60%, the functional layer is a honeycomb net, the honeycomb is filled with functional particles, and the functional layer is a polypropylene fiber layer. The functional particles are formed by loading manganese oxide and zinc oxide on an aluminum oxide molecular sieve, the content of the manganese oxide is 1-3%, and the content of the zinc oxide is 2-5%. The invention further discloses a preparation method of the air purification material with the antibacterial and mildew-proof functions. The air purification material has the advantages of being simple in structure, short in production process flow and the like.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to an antibacterial and mildew proof air purification material and a preparation method thereof. Background technique [0002] Air purification materials are widely used in air conditioning ventilation purification systems, air purifiers, car air conditioning filter elements and other equipment fields. At present, air purification materials mainly remove particulate matter and gaseous pollutants in the air. The removal of particulate matter is made of meltblown fibers to make high-efficiency filters. The filter uses activated carbon to absorb other pollutants in the air while intercepting particulate matter or aerosol pollutants in the air. After the high-efficiency filter intercepts the dust and aerosol in the air, a large amount of dust is formed on the surface and inside of the filter screen, which can easily cause the growth of bacteria, viruses, molds and o...

AI Technical Summary

Problems solved by technology

After the high-efficiency filter intercepts the dust and aerosol in the air, a large amount of dust is formed on the surface and inside of the filter screen, which can easily cause bacteria, viruses, molds and other microorganisms to breed, causing secondary pollution of bacteria and viruses

At present, the materials that make up the high-efficiency filter have problems such as large resistance, low efficiency, and low strength. In order to improve efficiency, the thickness of the material has to be increased, resulting in increased resistance. After time use, the hot melt adhesive volatilizes and causes the filter odor problem

If activated carbon adsorbs gaseous pollutants, if it is not replaced or disposed of in time, it will cause secondary emission of pollutants and cause secondary pollution

The HEPA filter and the activated carbon filter need to be processed and assembled separately, the production process is long and the cost is high
