Embodiment Construction

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

[0013] Polytetrafluoroethylene 14, polyvinylidene fluoride 4, kaolin 6, bauxite 12, activated carbon powder 32, copper powder 2, magnesium oxide 5, sodium bicarbonate 2, ammonium carbonate 2, fatty alcohol polyoxyethylene ether sulfate 1 . Aluminate coupling agent DL-411 6. Phenyltrichlorosilane 3. Azodicarbonamide 2. Modified bentonite 35. Appropriate amount of water.

[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...

Abstract

The invention provides a bauxite structural filter core and a preparation method thereof, and is characterized in that the structural filter core is prepared from the following raw materials, in parts by weight: 12-14 parts of polytetrafluoroethylene, 4-6 parts of polyvinylidene fluoride, 4-6 parts of kaoline, 10-12 parts of bauxite, 32-35 parts of an active carbon powder, 1-2 parts of a copper powder, 3-5 parts of magnesium oxide, 2-3 parts of sodium bicarbonate, 1-2 parts of ammonium carbonate, 1-2 parts of aliphatic alcohol polyoxyethylene ether sulfate, 4-6 parts of an aluminate coupling agent DL-411, 2-3 parts of phenyl trichlorosilane, 1-2 parts of azodicarbonamide, 25-35 parts of modified bentonite, and a proper amount of water. The bauxite structural filter core adopts polytetrafluoroethylene as the main material, has the advantages of acid resistance, alkali resistance, corrosion resistance and the like, can be used for various harsh environments, has the outstanding advantages of high purification efficiency, high temperature resistance, low pressure loss, corrosion resistance, long service life and the like, 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 bauxite structure 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, a...
