Abstract

The invention discloses an aminated gelatin-polypropylene composite air filter material which is composed of the following raw materials in parts by weight: 50-60 parts of polypropylene, 7-11 parts of silicon monoxide, 9-14 parts of powder activated carbon, 2-4 parts of 3-aminopropyltriethoxy silane coupling agent, 0.6-1.3 parts of glacial acetic acid, a right amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.5-1.5 parts of antioxidant 1010, 0.8-1.5 parts of titanate coupling agent, a right amount of gelatin phosphoric acid buffer solution, 4-9 parts of gelatin, 11-18 parts of diethylenetriamine, 2-5 parts of 1-(3-dimethylaminopropyl)-3-ethyl carbodiimide salt and a right amount of 5 mol / L hydrochloric acid solution. Alpha-quartz-containing silicon nanowires are prepared, and the activated carbon is utilized to carry the silicon nanowires treated by the silane coupling agent and added into the melt-blown polypropylene electret material, thereby effectively enhancing the adsorptivity of the filter material for harmful substances in air. The aminated gelatin-polypropylene composite air filter material has excellent filter efficiency.

Description

technical field [0001] The invention belongs to the field of air filtration, in particular to an aminated gelatin-polypropylene composite electret air filter material 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 filter materials provide the possi...
