The Eleventh Five-Year Plan period, China's steel slag output is by about 19,963 ten thousand t in 2006 about 28,214 ten thousand t that increase to 2010; Steel slag utilization rate brings up to 21% by 10%, and the accumulation volume of cargo in storage of steel slag has reached 92,577 ten thousand t.Although the comprehensive utilization ratio of slag is greatly improved, accumulation volume of cargo in storage is very high, also needs to improve slag comprehensive utilization level further.At present, the slag of China is mainly used in the building trade such as cement, brickmaking, is applied to the also relatively less of agricultural.
Slag and other organic-inorganic mixing of materials are prepared Chemical Mixed Fertilizer and are needed to use binding agent.Current Chemical Mixed Fertilizer binding agent is some mineral binder bonds such as wilkinite, Attapulgite mainly, and usage quantity is large, and invalid components is many; W-Gum is as organic binder bond, and after oxidation modification, tack is strong, and water-tolerant, has been widely used in the industries such as paper bonding at present.
Summary of the invention
In order to solve problems of the prior art, the invention provides a kind of organic binder bond and preparation method of recovery of stainless steel tailings Chemical Mixed Fertilizer, will make the organic binder bond being suitable for slag granulation after starch oxidation process modification, have consumption little, cohesive force is strong, meets the advantages such as compound fertilizer granule performance requriements.Its technical scheme is:
Principle of the present invention is: the present invention is oxidation cross-linked method, commercially available W-Gum is mainly side chain W-Gum, is first small molecules by oxidation by starch polymer chain rupture, then is increased by gelatinization that it is water-soluble, then be modified as cross-linked structure by borax, strengthened its cohesive strength.Finally add urea to increase its oilness, adding water is adjusted to proper volume and can obtains binder product.
An organic binder bond for recovery of stainless steel tailings Chemical Mixed Fertilizer, this binder formula is as follows: starch 10%, FeSO
40.03%, H
2o
20.3%, NaOH 0.6%, borax 0.03%, urea 0.5%.
A preparation method for the organic binder bond of recovery of stainless steel tailings Chemical Mixed Fertilizer, comprises the following steps:
(1) 45 DEG C by starch and distilled water in 1: 6 ratio mix, add FeSO
4beaded catalyst, stirs into uniform slurry;
(2) hydrogen peroxide of 30% is slowly added while stirring in the ratio of hydrogen peroxide and starch 0.03-0.035mL/g, if there is bubble, use tributyl phosphate froth breaking, rapid temperature increases to 60 DEG C constant temperature oxidation 60min, the NaOH solution of 20% is added, reaction 30min in the ratio of 0.3-0.35mL/g;
(3) borax soln of 3% is added in the ratio of 0.1mL/g, reaction 20min; Add the urea of 5%, reaction 20min;
(4) add water and be adjusted to proper volume, insulation 10min, be cooled to room temperature, whole process is carried out in water bath with thermostatic control.
Preferably, in described (1) step, starch is commercially available W-Gum, branched structure, and water ratio is 10%, and catalyst charge is 0.3%.
Preferably, in described (2) step, tributyl phosphate addition is that every 100g starch adds 3 ~ 4.
Preferably, in described (4) step, proper volume is that the volume ratio of starch and water is about 1: 10.
Preferably, described whole technological process uses electric mixer to stir, stirring velocity 120r/min.
Compared with prior art, beneficial effect of the present invention is:
The present invention utilizes oxidation cross-linked legal system for recovery of stainless steel tailings Chemical Mixed Fertilizer organic binder bond, and technique is simple, and cost is low, and product cohesive force is strong, and W-Gum can not to environment as agricultural-food.
Embodiment
Below in conjunction with embodiment, technical scheme of the present invention is described further.
Embodiment 1: the preparation of binding agent
(1) at 45 DEG C, 100g starch is poured in 600mL distilled water, add 0.3gFeSO
4beaded catalyst, stirs into uniform slurry.
(2) the hydrogen peroxide 3mL of 30% is slowly added while stirring, rapid temperature increases to 60 DEG C constant temperature oxidation 60min (if there is bubble, dripping 3 tributyl phosphate froth breakings).Add the NaOH solution 30mL of 20%, reaction 30min.
(3) the borax soln 10mL of 3% is added, reaction 20min; Add 5g urea, reaction 20min.
(4) adjusted volume that adds water is to 1L, and insulation 10min, is cooled to room temperature and gets final product (whole process is carried out in water bath with thermostatic control).
