Embodiment Construction

[0029] A low-cost environment-friendly melt-blown polypropylene electret air filter material consists of the following raw material components in parts by weight: polypropylene 55, silicon monoxide 12, powdered activated carbon 15, 3-aminopropyltriethoxysilane Coupling agent 3, glacial acetic acid 1, deionized water amount, low density polyethylene wax 2, antioxidant 1010 1.5, titanate coupling agent 1.2, peanut shell 4, zeolite powder 4, petroleum ether amount, absolute ethanol amount .

[0030] Specific steps are as follows:

[0031] (1) Raw material pretreatment:

[0032] Wash the peanut shells and dry them until the water content is 15wt%, crush them until the particle size is less than 1.5mm, then mix them with zeolite powder and immerse them in petroleum ether for 2 hours, then take them out and immerse them in absolute ethanol for 15 minutes, then take them out and dry them. dry, spare;

[0033] (2) Preparation of silicon nanowires:

[0034] ①. Place the small porce...

Abstract

The invention discloses a low-cost and environment-friendly type meltblown polypropylene electret air filter material. The low-cost and environment-friendly type meltblown polypropylene electret air filter material comprises raw material components in parts by weight as follows: 50-60 parts of polypropylene, 9-16 parts of silicon monoxide, 11-17 parts of powdered activated carbon, 1-4 parts of a 3-aminopropyltriethoxysilane coupling agent, 0.6-1.3 parts of glacial acetic acid, a proper amount of deionized water, 1-2.5 parts of low-density polyethylene wax, 0.5-2 parts of antioxidant 1010, 0.7-1.4 parts of a titanate coupling agent, 2-5 parts of peanut hulls, 3-5 parts of zeolite powder, a proper amount of petroleum ether and a proper amount of absolute ethyl alcohol. Silicon nanowires containing alpha-quartz are prepared and added to a meltblown polypropylene electret material, so that the material has excellent filter efficiency and a bacterial reproduction inhibiting function; the silicon nanowires treated with the silane coupling agent are supported by the activated carbon, the silicon nanowire supporting quantity of the activated carbon is increased, and the adsorption of hazardous substances in the air by the filter material is improved effectively.

Description

technical field [0001] The invention belongs to the field of air filtration, and in particular relates to a low-cost and environment-friendly melt blown polypropylene 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 filte...
