Embodiment Construction

[0013] An air purification filter element is made of the following raw materials in parts by weight (kg):

[0014] Ethylene-methyl acrylate copolymer (EMA 1125AC) 14-16, activated carbon powder 38-45, magnesium hydroxide 2-4, calcium hydroxide 3-5, ammonium bicarbonate 6-9, ammonium chloride 4-5, ethyl 4-6 propylene bis stearamide, 8-10 monoglyceride stearate, 4-6 dimethyl silicone oil, 2-3 sodium alginate, 35-45 modified bentonite.

[0015] Described modified bentonite is made by following method:

[0016] Calcinate bentonite at 520-540°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 2-3 hours, then soak it in 10-12% sodium hydroxide solution for 1-2 hours , take it out, wash it with pure water, dry it and grind it into powder; then add aluminum nitride equivalent to 40% of the weight of bentonite, 18% of apocynum powder, 3% of alum powder, 3% of zeolite powder, 4% of Tungsten carbide powder, mixed and stirred for 30-40 minutes, and...

Abstract

The invention provides an air cleaning filter core and a preparation method thereof. The invention is characterized in that the air cleaning filter core is prepared from the following raw materials by weight: 14 to 16 parts of an ethylene-methyl acrylate copolymer (EMA1125AC), 38 to 45 parts of active carbon powder, 2 to 4 parts of magnesium hydroxide, 3 to 5 parts of calcium hydrate, 6 to 9 parts of ammonium bicarbonate, 4 to 5 parts of ammonium chloride, 4 to 6 parts of ethylene bis(stearamide), 8 to 10 parts of glyceryl monostearate, 4 to 6 parts of dimethicone, 2 to 3 parts of sodium alginate and 35 to 45 parts of modified bentonite. The filter core material provided by the invention enables the removal rate of heavy metals to reach more than 99% and the removal rate of TVOC including formaldehyde and benzene to reach more than 95% and has a degerming and antibiosis rate as high as 99%. The filter core provided by the invention has the protruding advantages of high purification efficiency, high temperature resistance, small pressure loss, corrosion resistance, a long service life, removal of dust in air, etc.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to an air purification 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 environments, a...
