Abstract
The invention discloses a composite volcanic rock absorbent which is characterized in that the absorbent is prepared from the following raw materials, by weight: 8-15 parts of calcium carbonate fiber, 6-8 parts of iron tetroxide magnetic powder, 20-40 parts of tetrabutyl titanate, 3-5 parts of silica sol, 6-8 parts of calcium aluminate, 60-80 parts of volcanic rock, 6-9 parts of PA6 nylon powder, 3-4 parts of gelatin, 1-3 parts of ammonium bicarbonate, 5-8 parts of vermiculite powder, and deionized water. According to the invention, with the added vermiculite powder and iron tetroxide magnetic powder, volcanic rock absorbability, high-temperature resistance and fire resistance are enhanced; and an absorption range is expanded. The absorbent provided by the invention has good absorption characteristics in various fields and especially in the aspects of sewage treatment, oil pollution treatment and the like. The absorption efficiency is high, and the absorbent is easy to remove. The absorbent has a good reutilization effect, and has a good application prospect.
Description
Technical field
the present invention relates to a kind of absorbent fields, be specifically related to a kind of compound volcano rock adsorbent and preparation method thereof.
Background technology
Along with socioeconomic development, the destruction of each industry to environment is also on the rise, and especially grows with each passing day to the pollution of natural water.The sewage of the discharge such as paper-making industry, textile industry, chemical industry and steel industry enters in natural water, affects vegeto-animal growth in the self-purification capacity of natural water and water.Absorption is a kind of effective and protect the method for water quality efficiently, and it is not long that traditional adsorbent has service life, reuses weak effect, the not high situation of adsorption efficiency, undesirable to the removal effect of sewage.
Volcanic rock quality is hard as lithotome, coating surface honeycomb porous, specific area is large, and soak change without exception in water, water proofing property is splendid, fire prevention, weather resisteant is good, can prevent the deterioration caused because of ultraviolet, have nontoxic, tasteless, intensity is high, heat insulation, acid and alkali-resistance, stain resistance, corrosion-resistant, resistance toly to go mouldy, and the advantage such as pollution-free, "dead", as sorbent material, there is good application prospect.But the adsorbent hardness after preparation is inadequate, easy dry linting reduces service life, increase use cost, and adsorption rate and adsorption capacity is not high, so be badly in need of a kind of wear-resisting, easily separated, reusing is good, adsorption rate is fast, capacity is high adsorbent.
Summary of the invention
The object of this invention is to provide a kind of compound volcano rock adsorbent and preparation method thereof.
In order to realize object of the present invention, the present invention is by following scheme implementation:
A kind of compound volcano rock adsorbent, is made up of the raw material of following weight portion: calcium carbonate fiber 8-15, ferroferric oxide magnetic powder 6-8, butyl titanate 20-40, Ludox 3-5, calcium aluminate 6-8, volcanic rock 60-80, PA6 nylon powder 6-9, gelatin 3-4, carbonic hydroammonium 1-3, vermiculite power 5-8, deionized water;
A kind of compound volcano rock adsorbent of the present invention, be made up of following concrete steps:
(1) absolute ethyl alcohol of butyl titanate and 3-4 times amount is mixed, magnetic agitation 1h, magnetic agitation 2h is continued again by being added in above-mentioned solution after short for calcium carbonate fiber cutting, slow dropping deionized water, continue after gel to be formed to stir 0.5-1 hour, then to be added in baking oven that under 80 ° of C, to dry grinding for subsequent use;
(2) spend deionized water after volcanic rock being soaked 12h in concentrated sulfuric acid and grind to form fine powder to neutral oven dry, then mix with gelatin, PA6 nylon powder, in Muffle furnace, under 240-255 ° of C, calcine 0.5-1h, take out after cooling;
(3) by the product of step (1) gained and except calcium aluminate all the other remaining material mixing and stirring, employing pressure is that mixture is pressed into bead by the ball press of 10t-20t, selects particle size for subsequent use as ball core at the bead of 5-15mm scope after screening;
(4) product of step (2) gained and calcium silicates are mixed, the bead of step (3) gained is placed in disc balling machine as kernel, add above-mentioned volcanic rock mixture, rolling pelletizing, volcanic rock is covered on ball core and forms shell, the composite sphere of gained is calcined under 550-600 ° of C 2-4h and become porous complex microsphere.
Advantage of the present invention is: the present invention adopts calcium carbonate fiber to mix with TiO 2 sol, enhance the intensity of TiO 2 sol, bactericidal properties, the performance of the aspect such as adsorbance and heat resistance, adopt gelatin and PA6 to be added to define skeleton when calcining in volcanic rock and make Adhesion enhancement between volcanic rock, not easily be scattered when making adsorbent dry linting, wearability strengthens, extend service life, and double-layer porous road adsorption microspheres made by adsorbent by the present invention, enhance adsorption capacity and adsorption rate, to tiny field trash, there is good adsorption effect, expand adsorption range, the vermiculite power added and ferroferric oxide magnetic powder enhance the adsorptivity of volcanic rock, heat-resisting quantity and fire line, expand adsorption range, adsorbent prepared by the present invention all has good characterization of adsorption in each field, especially in sewage disposal, the aspects such as oily waste treatment, adsorption efficiency is high, and easily remove, reuse effective, application prospect is extensive.
