Problems solved by technology

[0003] The air filter medium in the prior art generally adopts paper fiber, glass fiber, polymer fiber and activated carbon, wherein the paper fiber has a limited life due to the unique non-corrosion resistance or weather resistance of paper; glass fiber is suspected to be Carcinogens, so it is not desirable to use them in air filters, and activated carbon can only absorb harmful gases but cannot filter PM2.5, so the production of air filter products is more complicated, and the cost remains high. It can be seen that it is necessary to develop a moderate cost, The process is simple, can effectively filter PM2.5 in the air, filter medium for absorbing TVOC gas and harmful microorganisms and its preparation process

Abstract

The invention relates to the field of air purifying, in particular to a filtering material for air purifying and a preparation method of the filtering material for air purifying. The filtering material for air purifying is mainly prepared by compositing a polarized melt-blown polypropylene non-woven fabric filtering layer, a composite natural bamboo fiber filtering layer and a polyester staple fiber filtering layer sequentially, wherein the composite natural bamboo fiber filtering layer is formed by compositing polypropylene staple fibers and natural bamboo fibers. The preparation method of the filtering material for air purifying is simple and easy for industrial production. The filtering material for air purifying has the advantages that by means of mutual cooperation of all the layers, the filtering material for air purifying is good in air permeability, highly resistant to heat and capable of filtering dust in air quickly, adsorbing harmful gas in the air, inhibiting and killing harmful microorganisms in the air and releasing negative ions to enable the air to be more purified so as to achieve remarkable purifying effects.

Description

Technical field [0001] The invention relates to the field of air purification materials, in particular to a filter material for air purification and a preparation method thereof. Background technique [0002] With the development of the economy, the wide application of a large number of new decorative materials indoors (including automobiles) has led to further aggravation of indoor air pollution. In addition, people's indoor life activities have also caused certain pollution, and indoor air quality problems have become more prominent . Indoor air quality is closely related to human health. Among them, volatile organic compounds (TVOC), PM2.5 and other pollutants are the most harmful to humans. [0003] Air filter media in the prior art generally use paper fibers, glass fibers, polymer fibers and activated carbon. Among them, paper fibers have a limited life span due to the unique corrosion or weather resistance of paper; glass fibers are suspected to be Carcinogens, therefore, d...
