Abstract

The invention discloses a polypropylene electret air filter material containing tencel fiber. The material is prepared from, by weight, 50-60 parts of polypropylene, 9-13 parts of silicon monoxide, 11-17 parts of powdered activated carbon, 2-4 parts of 3-aminopropyl triethoxy silane coupling agent, 0.7-1.6 parts of glacial acetic acid, a proper amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.5-2 parts of antioxidant 1010, 0.8-1.5 parts of coupling agent of organic titanate, 5-10 parts of tencel fiber and a proper amount of 50% sodium hydroxide solution. Silicon nanowires containing alpha-quartz are prepared and added to the melt-blow polypropylene electret air filter material, and outstanding filtering efficiency is achieved; the silicon nanowires processed by the silane coupling agent are loaded on activated carbon, the loading capacity of activated carbon for the silicon nanowires is improved, the adsorption of the filtering material to harmful substances in air is effectively improved, and the product has excellent filtering performance.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to a polypropylene electret air filter material containing tencel fibers and a preparation method thereof. technical background [0002] With the progress of the times, people's requirements for environmental quality are getting higher and higher. However, the rapid economic development has aggravated the pollution of the environment, and the dust, chemicals, and harmful microorganisms in the air have had adverse effects on people's health. Therefore, effective control of harmful substances in the air is a major problem to be solved. The application of air filters and filter materials is an important means of purifying the air. Ordinary air filter materials are not thorough enough to remove fine particles, and harmful microorganisms are easy to breed on the filter materials, and there is a possibility of secondary pollution. Electret air filter materials provide the poss...
