Embodiment Construction

[0012] A filter core for adsorbing microparticles, made of the following raw materials in parts by weight (kg):

[0013] Kaolin 43, bamboo charcoal powder 23, molecular sieve powder 12, sodium hydroxide 3, potassium feldspar powder 8, lapis lazuli powder 12, low density polyethylene 16, ethylene glycol 9, Freon 2, zirconium diboride 6, lauryl polyoxygen Vinyl ether 4, silane coupling agent KH792 6, modified bentonite 35.

[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 alum powder, 3% of zeolite powder, 4% of Tungsten carbide powder, mixed and stirred for 30-40 minutes, and then spraye...

Abstract

The invention provides a filter core for adsorbing microparticles and a preparation method thereof, and is characterized in that the filter core is prepared by the following raw materials, in parts by weight: 43-45 parts of kaolin, 20-23 parts of a bamboo charcoal powder, 10-12 parts of a molecular sieve powder, 3-5 parts of sodium hydroxide, 6-8 parts of a potassium feldspar powder, 9-12 parts of a celestite powder, 16-18 parts of low-density polyethylene, 6-9 parts of ethylene glycol, 2-3 parts of freon, 4-6 parts of zirconium diboride, 3-4 parts of lauryl alcohol polyoxyethylene, 6-8 parts of a silane coupling agent KH792, and 30-35 parts of modified bentonite. The filter core for adsorbing the microparticles has the outstanding advantages of high porosity, large adsorption capacity, 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, and in particular relates to an adsorption micro particle 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 worki...
