Embodiment Construction

[0012] A microporous nano-silver active filter element is made of the following raw materials in parts by weight (kg):

[0013] Polyvinylidene fluoride 21, ethylene-methyl acrylate copolymer (EMA 1214AC) 14, polyoxyethylene abietic acid 4, ammonium bicarbonate 6, silver nitrate 2, sepiolite powder 20, bamboo charcoal powder 12, ABS superfine powder 5 , soybean oil 8, alum powder 4, ditungsten boride 2, sodium sulfate 1, modified bentonite 35.

[0014] Described modified bentonite is made by following method:

[0015] Calcinate bentonite at 490-520°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 3-4 hours, take it out, wash it with pure water, dry it and grind it into powder; then add quite Add 40% aluminum nitride by weight of bentonite, 3% alum powder, 3% zeolite powder, and 18% Tianji yellow powder, mix and stir for 30-40 minutes, and then spray methyl alcohol equivalent to 5% by weight of bentonite. Triethoxysilane, st...

Abstract

The invention discloses a micropore nano-silver active filter core and a preparation method thereof, and is characterized in that the micropore nano-silver active filter core is prepared from the following raw materials, in parts by weight: 18-21 parts of polyvinylidene fluoride, 12-14 parts of ethylene-methyl acrylate copolymer (EMA1214AC), 4-6 parts of rosin-polythylene oxide ester, 4-6 parts of ammonium hydrogen carbonate, 1-2 parts of silver nitrate, 20-23 parts of a sepiolite powder, 10-12 parts of a bamboo charcoal powder, 5-8 parts of an ultrafine powder of ABS, 6-8 parts of soybean oil, 3-4 parts of an alum powder, 1-2 parts of tungsten boride, 1-2 parts of sodium sulfate, and 25-35 parts of modified bentonite. The micropore nano-silver active filter core has the functions of sterilization and adsorption, can be recycled, has the outstanding advantages of acid resistance, alkali resistance, salt spray resistance, high purification efficiency, high temperature resistance, low pressure loss, corrosion resistance, and long service life, and can also remove micro-dust in air.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to a microporous nano-silver active filter element and a preparation method thereof. Background technique [0002] Filter materials are widely used in chemical industry, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries; the most common ones are automotive air filters, which are used to filter the air entering the engine, and remove particulates and particles in the air. Mechanical impurity components are blocked, preventing these components from entering gasoline, diesel or engine oil, and ensuring the normal operation of the engine. There are also a large number of filter materials used in air conditioning systems. Now the environmental air pollution is very serious, which greatly endangers human health. Air filter materials can absorb various harmful particles in the air, prevent them from entering people's living or working...
