Embodiment Construction

[0028] A water-resistant polypropylene hybrid electret air filter material, composed of the following raw material components in parts by weight: polypropylene 55, silicon monoxide 10, powdered activated carbon 15, 3-aminopropyltriethoxysilane coupling Agent 3, glacial acetic acid 1, appropriate amount of deionized water, low density polyethylene wax 2, antioxidant 1010 1.5, titanate coupling agent 1, TMP-2000 1.5, chopped glass fiber 4.

[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 time, blow air into the fu...

Abstract

The invention discloses a washing-resistant polypropylene hybridized electret air filter material. The material is prepared from, by weight, 50-60 parts of polypropylene, 8-12 parts of silicon monoxide, 10-16 parts of powdered activated carbon, 2-5 parts of 3-aminopropyl triethoxy silane coupling agent, 0.5-1.5 parts of glacial acetic acid, an appropriate amount of deionized water, 1-3 parts of low-density polyethylene wax, 0.5-2 parts of an antioxidant 1010, 0.8-1.5 parts of a titanate coupling agent, 1-2 parts of TMP-2000 and 3-6 parts of chopped glass fibers. By addition of alpha-quartz containing silicon nanowires into a melt-blown polypropylene electret material, remarkable filter efficiency is achieved, and an evident bacterial reproduction inhibiting function is realized. By adoption of activated carbon for loading the silicon nanowires treated by the silane coupling agent, silicon nanowire load capacity of the activated carbon is increased, and adsorption of the filter material to harmful substances in air can be effectively improved.

Description

technical field [0001] The invention belongs to the field of air filtration, in particular to a water-resistant polypropylene hybrid 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 possibilit...
