Embodiment Construction

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

[0014] Activated carbon powder 14, microporous polyethylene powder 45, silver nitrate 1, sodium chloride 4, silane coupling agent KH550 3, zirconium fluoride 1, graphite 4, silicon carbide 2, attapulgite 4, urea 3, azodicarbonate Formamide 1, modified attapulgite 12, polyvinyl alcohol 4, appropriate amount of water;

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

[0016] Calcinate attapulgite at 450-500°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 1-2 hours, take it out, wash it with pure water, dry it and grind it into powder; Add aluminum nitride equivalent to 40% of the weight of attapulgite, 23% of Gynostemma powder, 3% of aluminum hydroxide, 3% of zirconium fluoride, 3% of graphite, 4% of sodium bicarbonate, mix and stir for 30- After 40 minutes, spray silane coupling agent KH550 equi...

Abstract

The invention discloses an active carbon air filter element and a preparation method thereof. The active carbon air filter element comprises following raw materials, by weight, 12 to 14 portions of active carbon powder, 40 to 45 portions of microporous polyethylene powder, 1 to 2 portions of silver nitrate, 3 to 4 portions of sodium chloride, 2 to 3 portions of silane coupling agent KH550, 1 to 2 portions of zirconium tetrafluoride, 3 to 4 portions of graphite, 1 to 2 portions of silicon carbide, 4 to 6 portions of attapulgite, 2 to 3 portions of urea, 1 to 2 portions of azodicarbonamide, 12 to 14 portions of modified attapulgite, 3 to 4 portions of polyvinyl alcohol and an appropriate amount of water. Silver nitrate is taken as one of the raw materials of the active carbon air filter element, so that when the active carbon air filter element is used for filtration and adsorption, silver ions are capable of sterilizing, and realizing further purifying of air or water. Silicon carbide is taken as one of the raw materials, and is capable of improving wear resistance and strength of the active carbon air filter element. The active carbon air filter element is suitable to be used in severe environment; is high in purification efficiency, less in pressure loss, and long in service life; is resistant to high temperature and corrosion; and is capable of removing micro dust in the air.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to an activated carbon air 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...
