Embodiment Construction

[0012] A straw powder filter element is made of the following raw materials in parts by weight (kg):

[0013] Straw powder 24, clay 12, zirconium fluoride 5, polyvinyl alcohol 8, propylene glycol 4, sodium metasilicate 5, charcoal 10, clay 22, modified attapulgite 23, and appropriate amount of water.

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

[0015] 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 equivalent to 15% of the weight of attapulgite, and stir at 12000-15000 rpm for 60-80 minutes to obtain the product.

Abstract

The invention discloses a straw powder filter element and a preparation method thereof. The straw powder filter element comprises following raw materials, by weight, 20 to 24 portions of straw powder, 12 to 14 portions of white clay, 3 to 5 portions of zirconium tetrafluoride, 6 to 8 portions of polyvinyl alcohol, 4 to 6 portions of propylene glycol, 4 to 5 portions of sodium metasilicate, 10 to 12 portions of charcoal, 20 to 22 portions of clay, 23 to 25 portions of modified attapulgite, and an appropriate amount of water. Straw powder is taken as a raw material, and is converted into active carbon by sintering; and active carbon possesses relatively high adsorption ability. The straw powder filter element is high in purification efficiency, 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 a straw powder filter core 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, and reduce...
