Sponge vegetable tallow mesh membrane material for purifying air and preparation method of sponge vegetable tallow mesh membrane material

Abstract

The invention relates to a sponge vegetable tallow mesh membrane material for purifying the air and a preparation method of the sponge vegetable tallow mesh screen material. The vegetable tallow meshscreen sponge material is prepared from air purifying vegetable tallow adhesive having an air purifying function, and a skeleton carrier prepared from sponge with an aperture of 20 to 120 meshes according to the size of the dust particle, and the sponge vegetable tallow mesh screen material is prepared from the raw materials such as polylactic acid, beewax, medical vaseline, methylsilicone oil, sodium chloride, ammonium sulfate and cotton fibers and is high in hygroscopicity, so that the difficulty in achieving the normal effect after the material is used for 600 days can be solved. The dust of 0.01 micrometer and nanoscale dust accumulated after the filtering can be avoided, the moldy mold does not reoccur, the formaldehyde can be decomposed and oxidized efficiently, the removal rate of the formaldehyde is 99.91 percent, the purification rate of PM2.5 is 99.98 percent, the removal rate of benzene is 98.6 percent, the rate for killing the staphylococcus aureus is 99.18 percent, the wind resistance is low, and the blockage is prevented, and when used in various air purifying and filtering devices, the sponge vegetable tallow mesh screen material has creativity, novelty and practicability.

Description

technical field [0001] The invention relates to an air-purifying sponge plant lipid omentum material and a preparation method thereof. The plant lipid omentum sponge material is mainly used in various air purification and filtering equipment, and belongs to the field of environmental protection materials. Background technique [0002] As we all know, the air purification filters on the market are mainly filled or bonded filters. 1. The filled filter is to fill the purified particles after granulation into the purified filter. This filter contains There are many purification particles in the filter, but because there is no other support inside the filter, the accumulation of the particles reduces the contact area with the air, making it difficult to improve the purification efficiency; 2. The bonded filter is the purification material powder Bonded to the surface of the filter with an adhesive, the load of the purification material depends on the pore size of the filter, the ...

[0002] As we all know, the air purification filters on the market are mainly filled or bonded filters. 1. The filled filter is to fill the purified particles after granulation into the purified filter. This filter contains There are many purification particles in the filter, but because there is no other support inside the filter, the accumulation of the particles reduces the contact area with the air, making it difficult to improve the purification efficiency; 2. The bonded filter is the purification material powder Bonded to the surface of the filter with an adhesive, the load of the purification material depends on the pore size of the filter, the overall load of the purification material is not much, it is difficult to achieve the best purification effect, and in the process of use, The powder purification material on its surface is easy to fall off, and there are potential safety hazards during use

3. Adsorption method, that is, the use of porous substances with adsorption capacity (such as activated carbon, HEPA high-efficiency filter, etc.) to transfer pollutants from the gas phase to the adsorbent, but this method cannot degrade the pollutants, and the adsorbent is saturated Afterwards, it must be reprocessed before it can continue to be used; 4. The photocatalyst has a small load, which limits its purification efficiency. There is a risk of unsafety, and the service life of the filter screen is not high

The original forms of these purification materials are powder materials. After being bonded into the pores of the porous carrier, it is easy to cause the pores to be blocked. In addition, the fine powder particles are easily covered by glue and cannot be in contact with the outside air, resulting in failure to purify the air. Effect

Also do not have a kind of structural design reasonable at present, purification efficiency is high, wind resistance is little, safe to use, the sponge plant fat omentum material and preparation method thereof of air purification of processing convenience
