Abstract

The invention belongs to air filtering materials, and particularly relates to an air filtering membrane preparation method. The air filtering membrane preparation method includes that by selecting aloe Leaves as a base material, and cooking the aloe Leaves together with calcium chloride, calcium content in the aloe Leaves is increased; by combining leucine with calcium ions, chelated calcium is formed, combination of amino acid and aloe vera gel is improved; by mixing hexamethyldisiloxane and N,N-dimethylacrylamide with the aloe vera gel and performing polymerization, the aloe vera gel is parceled; by crosslinking the calcium ions with amide groups, ventilating performance is improved. The air filtering membrane preparation method has the advantages that by polymerization of the hexamethyldisiloxane and the N,N-dimethylacrylamide, membrane-forming performance is improved, and resistance to air ventilation is reduced; by the aid of performance of the aloe leaves, antibacterial capability of an air filtering membrane is enhanced, and the air filtering membrane good in filtering effect and high in breathability can be obtained.

Description

technical field [0001] The invention belongs to air filter materials, in particular to a preparation method of an air filter membrane. Background technique [0002] Indoor air pollution means that the amount of air pollutants entering the room exceeds the self-purification capacity of the indoor environment, resulting in the decline and deterioration of the indoor air quality, which directly or indirectly has adverse effects on people. Human beings spend at least 70% of their time indoors, but due to the influence of decoration, household chemicals, cigarette smoke, etc., indoor environmental pollution has become the third generation of pollution after "soot pollution" and "photochemical smog pollution". In recent years, PM2.5 has exceeded the standard in most parts of my country, and indoor air quality has also been greatly affected. In addition, the southeastern coastal area of ​​my country belongs to the subtropical monsoon climate, and the air is humid all year round. T...
