Long-acting electret air filtration material with anti-corrosion and anti-mildew effects and preparation method thereof

Abstract

The invention discloses a long-acting electret air filtration material with anti-corrosion and anti-mildew effects. The long-acting electret air filtration material with the anti-corrosion and anti-mildew effects comprises the following raw material components: 50-60 parts of polypropylene, 7-13 parts of silicon monoxide, 12-15 parts of powdered active carbon, 1-4 parts of a 3-aminopropyltriethoxysilane coupling agent, 0.6-1.4 parts of glacial acetic acid, a proper amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.6-2 parts of an antioxidant 1010, 0.7-1.3 parts of a titanate coupling agent, 4-9 parts of sorbic acid, 5-11 parts of malic acid and 3-6 parts of 8-quinolinol copper. Through the long-acting electret air filtration material with the anti-corrosion and anti-mildew effects, silicon nanowires containing alpha-quartz are prepared and are added into a melt-blown polypropylene electret material, so that the electret material has excellent filtration efficiency and also has a function of obviously inhibiting bacterial reproduction; the silicon nanowires treated by the silane coupling agent are loaded by active carbon; the silicon nanowire loading capacity of the active carbon can be improved; the adsorption of the filtration material to harmful substances in the air can be effectively improved.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to an electret air filtration material with long-lasting anti-corrosion and anti-mildew effects and a preparation method thereof. [0002] technical background [0003] 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 fi...
