Embodiment Construction

[0012] A structural filter element for removing benzene in drinking water, made of the following raw materials in parts by weight (kg):

[0013] Bentonite 24, sodium sulfide 6, silver nitrate 1, brown sugar 5, zeolite powder 7, tributyl citrate 1, silicone resin 4, silane coupling agent KH550 4, nano silicon dioxide 5, modified bentonite 35, water amount .

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

[0015] 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 brown sugar, 3% of zeolite powder, and 4% of carbonized Tungsten powder, mixed and stirred for 30-40 minutes, and then sprayed with 7% bentonite weight Cross-linking agent...

Abstract

The invention discloses a structural filter core for removal of benzene in drinking water and a preparation method thereof, and is characterized in that the structural filter core is prepared form the following raw materials, in parts by weight: 24-26 parts of bentonite, 4-6 parts of sodium sulfide, 1-2 parts of silver nitrate, 3-5 parts of brown sugar, 5-7 parts of a zeolite powder, 1-2 parts of tributyl citrate, 4-6 parts of organic silicon resin, 3-4 parts of a silane coupling agent KH550, 3-5 parts of nanosilicon dioxide, 25-35 parts of modified bentonite, and a proper amount of water. The structural filter core has a sterilization effect, has better absorption of heavy metal particles in air and water, has the outstanding advantages of 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 structural filter element for removing benzene in drinking water 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 l...
