Embodiment Construction

[0021] The parts indicated in the following examples all refer to parts by mass, and the concentrations are all percentages by mass.

[0022] Example 1:

[0023] (1) Dissolve 10 parts of polyvinylpyrrolidone powder into 90 parts of absolute ethanol, stir magnetically for 2 hours, and then carry out solution electrospinning after standing for 1 hour (spinning distance 10cm, voltage 15KV, liquid supply rate 0.2ml / h).

[0024] (2) Combine ZnO and MnO 2 Add the particles into absolute ethanol and stir for 2 hours, then heat and stir to 80°C to obtain a suspension, add silane coupling agent that accounts for 2% of the mass fraction of the two particles into the suspension drop by drop, and continue stirring 1 hour, filter and dry. Then 100 parts of polypropylene, surface-treated ZnO and MnO 2 10 parts of microparticles, 0.5 parts of antioxidant 168, and 15 parts of polyester plasticizer were fully mixed, and melt electrospinning was carried out (spinning temperature: 230°C, sp...

Abstract

The invention discloses an antibacterial composite fiber membrane for removing haze particles and formaldehyde and a preparation method of the antibacterial composite fiber membrane. The membrane is composed of a polymer nanometer fiber layer and a polymer-metal oxide composite superfine fiber layer. The membrane has multiple and efficient air purification functions, and can be persistently antibacterial and remove harmful substances in air, such as haze particles and formaldehyde. The soaping degree is high, the membrane is reusable, and the service life of the membrane is prolonged. After a protective fiber layer or other fiber layers are added to the outer surface of the composite fiber membrane, the composite fiber membrane can be used for masks, air purifiers, clean room air filtration systems, air conditioners and the like. Moreover, the spinning components, the ratio and the number of fiber layers can be adjusted at will so as to meet different functions and demands. The composite fiber membrane has the advantages of low cost, simple preparation process, energy conservation, low consumption and no secondary pollution.

Description

technical field [0001] The invention relates to the preparation of an organic-inorganic composite functional fiber membrane by using electrospinning technology, so that it has the performance of not only removing smog and haze particles, but also highly efficient antibacterial and formaldehyde removal, so as to achieve the effect of purifying air. Background technique [0002] The rapid development of modern industry, while promoting economic growth, has also caused huge environmental pollution, whose intensity has exceeded the self-purification ability of the environment, and the bacteria, harmful gases and inhalable particulate matter (such as PM2.5, etc.) in the air have increased sharply , resulting in a substantial drop in air quality, threatening the living environment and health of human beings. Human beings have to vigorously develop science and technology to deal with environmental problems and provide themselves with a healthy living environment. In this context, ...
