Abstract

The invention discloses a polypropylene electret air filtering material containing graphene oxide. The polypropylene electret air filtering material comprises, by weight parts, 50-60 parts of polypropylene, 6-10 parts of silicon monoxide, 8-14 parts of powdered activated carbon, 1-4 parts of aminopropyl triethoxy silane coupling agent, 0.6-1.4 parts of glacial acetic acid, an appropriate amount of deionized water, 1-3 parts of low density polyethylene wax, 0.8-2 parts of antioxidant 1010, 0.7-1.4 parts of titanate coupling agent, 4-7 parts of graphene oxide, an appropriate amount of N,N-dimethylformamide, 0.7-1.5 parts of toluene diisocyanate, 0.8-1.6 parts of dibutyltin dilaurate and an appropriate amount of acetone. Silicon nanowires containing alpha-quartz are prepared, the silicon nanowires loaded by activated carbon and treated through the silane coupling agent are added into a melt-blown polypropylene electret material, the adsorption of harmful substances in air by the filtering material is effectively improved, and the filtering material has excellent filtering efficiency.

Description

technical field [0001] The invention belongs to the field of air filtration, in particular to a polypropylene electret air filter material containing graphene oxide 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 possibility to ...
