Abstract
The invention discloses an adsorption filtering agent with sound absorption and flame-retardant functions. The adsorption filtering agent is prepared from the following raw materials, by weight, 55-58 parts of diatomite, 9-16 parts of stone flour, 20-25 parts of fresh pine needle, 10-15 parts of aloe, 18-25 parts of wood chips, 18-28 parts of nano-xonotitle powder, 2.8-4.8 parts of nano-titanium dioxide, 5-7 parts of ceramic fiber, 1-2 parts of magnesium sulfate, 2-3 parts of aluminium chloride, 8-11 parts of an aqueous polyurethane emulsion and a proper amount of water. The prepared adsorption filtering agent has advantages of rough and hard surface, large specific surface area, high porosity, good adsorption filtering performance, high strength and low cost. The adsorption filtering agent is easy to popularize and use. Through a physical and chemical modification method, nano-titanium dioxide is loaded on the surface of diatomite so as to decompose organic pollutants into carbon dioxide and oxygen. Thus, harmful substances adsorbed on diatomite are reduced, and service life of the adsorption filtering agent is prolonged.
Description
Technical field
The present invention relates to absorption filter agent field of material technology, be specifically related to a kind of to there is absorption filter agent of sound-absorbing and flame-retardant function and preparation method thereof.
Background technology
Along with the fast development of process of industrialization, air quality problems is increasingly serious, especially the healthy of people in nationwide haze serious threat in recent years, the side effect brought thus is also day by day serious, wherein arch-criminal is exactly the flue dust of the discharge such as kiln head and tail, furnace of calcium carbide, ferro-alloy furnace of the industries such as domestic building materials, chemical industry, metallurgy, and cleaner the most frequently used is at present exactly sack cleaner.Sack cleaner is a kind of dry type dust filtration device, after filtrate uses a period of time, due to effects such as sieving, collision, delay, diffusion, electrostatic, one deck dust has been gathered on filter bag surface, this layer of dust is called bonding layer, and in motion process after this, bonding layer has become the main filtration layer of filtrate, rely on the effect of bonding layer, the filtrate that mesh is larger also can obtain higher filter efficiency.But the utilization of bonding layer is abundant not in real-world operation process, cause that dust removing effects is low, the consequences such as erosion corrosion situation is serious after filtrate Long-Time Service, the absorption filter agent being badly in need of a kind of efficient function diversification is sprayed on filter material surface and is used as bonding layer use before deduster is started working, both can improve the dust removing effects of deduster, the harmful exhaust that absorption is fallen to discharge can also have been filtered.
Summary of the invention
Object of the present invention is just to provide a kind ofly has absorption filter agent of sound-absorbing and flame-retardant function and preparation method thereof, to overcome the deficiencies in the prior art.
The object of the present invention is achieved like this:
A kind of absorption filter agent with sound-absorbing and flame-retardant function, it is characterized in that, be made up of the raw material of following weight portion: diatomite 55-58, stone flour 9-16, fresh pine needle 20-25, aloe 10-15, wood chip 18-25, nanometer eakleite powder 18-28, nano titanium oxide 2.8-4.8, ceramic fibre 5-7, magnesium sulfate 1-2, aluminium chloride 2-3, aqueous polyurethane emulsion 8-11, suitable quantity of water.
Described a kind of preparation method with the absorption filter agent of sound-absorbing and flame-retardant function, is characterized in that comprising the following steps:
(1) ceramic fibre is pulverized 120-180 mesh sieve, added nano titanium oxide, aqueous polyurethane emulsion agitation grinding 1-2 hour, at 150-180 DEG C, dry obtained modified nano-titanium dioxide;
(2) fresh pine needle, aloe, wood chip drying and processing 5-8 hour at 105-110 DEG C is got, add diatomite in 400-450 DEG C of high-temperature calcination process 2-4 hour, cooling is pulverized to drop in high mixer and is added modified nano-titanium dioxide in 180-220 DEG C of mix and blend 30-50 minute;
(3) added water to be stirred to by magnesium sulfate and dissolve completely, add step (2) material stirring 10-20 minute, be warming up to 80-120 DEG C and continue to stir 30-40 minute, then add stone flour and other residual components dispersion grinding 2-3 hour, granulation is dried, discharging.
The present invention has following beneficial effect: the absorption filter agent rough surface that the present invention obtains is hard, specific area is large, porosity is high, Adsorption Filtration Properties is good, intensity is high, with low cost being easy to is promoted the use of, by physical and chemical modified method, nano titanium oxide is carried on diatomite surface, organic pollution can be decomposed into carbon dioxide and oxygen, thus reduce absorption harmful substance over celite, extend absorption filter agent service life, be sprayed on deduster filtrate and also there is good sound-absorbing and flame-retardant function, reduce noise pollution, be adapted at using during high-temperature smoke is administered.
