Embodiment Construction

[0028] A polypropylene electret air filter material with flame-retardant properties, composed of the following raw material components in parts by weight: polypropylene 55, silicon monoxide 11, powdered activated carbon 14, 3-aminopropyltriethoxysilane coupling Agent 3, glacial acetic acid 1.2, deionized water amount, low density polyethylene wax 2, antioxidant 1010 1.6, titanate coupling agent 1, antimony trioxide 2, zinc borate 1, decabromodiphenylethane 3 .

[0029] Specific steps are as follows:

[0030] (1) Preparation of silicon nanowires:

[0031] ①. Place the small porcelain boat containing silicon monoxide powder horizontally in the middle of the alumina tube, then place the tube in a high-temperature tube furnace, vacuumize at 100Pa, and then raise the temperature to 200 and 900°C respectively Keep warm for 60 minutes, then heat up to 1200°C for 4 hours;

[0032] ②. Afterwards, cool down to 600°C at a rate of 2°C / min and keep it warm for 30 minutes. At the same ti...

Abstract

The invention discloses a polypropylene electret air filtering material with flame retardant performance. The material is prepared from, by weight, 50-60 parts of polypropylene, 9-15 parts of silicon monoxide, 12-18 parts of powdered activated carbon, 1-4 parts of 3-aminopropyl triethoxy silane coupling agent, 0.8-1.6 parts of glacial acetic acid, a proper amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.5-1.8 parts of antioxidant, 0.8-1.5 parts of titanate coupling agent, 1-3 parts of antimonous oxide, 0.8-2 parts of zinc borate and 2-4 parts of decabrominated dipheny ethane. Prepared silicon nanowires containing alpha-quartz are added to the melt-blowing polypropylene electret material, and outstanding filtering efficiency is achieved; according to the silicon nanowires loaded by the activated carbon and processed through the silane coupling agent, the loading amount of the silicon nanowires by the activated carbon is improved, and the adsorption of the filtering material to harmful substances in air is effectively improved.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to a polypropylene electret air filtration material with flame-retardant performance 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 materi...
