Description
Technical field
The present invention relates to Industrial Solid Waste application technology as the second resource fields, and in particular to a kind of multiple elements design steel slag grinding aid.
Background technology
Slag is one of main waste residue of steel and iron industry, mainly by the oxide of calcium, iron, silicon, magnesium and a small amount of aluminium, manganese, phosphorus etc.
Composition, mineral facies for tricalcium silicate, dicalcium silicate, monticellite, calcium and magnesium rhodonite, calcium aluminoferrite and silicon, magnesium, iron,
The solid solution that manganese, the oxide of phosphorus are formed, also containing a small amount of free calcium oxide and metallic iron, fluor-apatite etc..Slag be
Extract impurity and the solid-state castoff that largely generates with lime in steelmaking process, discharge capacity account for output of steel 10%~
15%.In recent years, with the increase of output of steel, slag accumulation is more and more, and utilization rate only has 20% or so, right combination profit
Had become with slag one of must solve the problems, such as at present.
Slag is primarily present following both sides property, on the one hand, the grindability of slag is very poor：Slag compact structure, root
According to the related indexs of national standard GBJ92286, slag can be classified as the row of most hard rock, more wear-resisting, and grinding pow consumption is high；And
And slag contains 5%~10% residual steel, magnetic separation is not net, influences the utilization of slag in tailings containing metal.On the other hand, steel
The early activity of slag is very low：Due to containing the mineral C3S with hydraulic gelling in slag（Tricalcium silicate）And C2S（Silicic acid
Dicalcium）, wherein, although from the point of view of cement minerals, C3S can play a major role to early strength, slag warp
1650 DEG C or so high-temperature fusions form " dead roasting ", and crystallizable mineral is fine and close, and the hydration activity of C3S will be within considerable time
It can bring into play, and C2S can only contribute to later strength, in the case of being suitble to exciting agent in nothing, the morning of slag
Phase hydration activity is very low, so as to which activity index is relatively low.
Grinding aid product currently on the market is mainly for clinker and the plain edition grinding aid of the preferable mixing material of grindability, example
Such as, the Chinese patent literature of Application No. 200510047822.6 reports a kind of multifunctional cement grinding aid, be flyash,
Sodium chloride, triethanolamine, sodium metasilicate, zinc ore mountain flour, sodium benzoate, gypsum, the mixture of diethylene glycol, the weight of the mixture
Than for：Flyash is 10~60%, sodium chloride 15~55%, triethanolamine 5~35%, sodium metasilicate 0.05~
10%, zinc ore mountain flour 0.3~12%, benzene first trisodium 0.2~8%, gypsum 0.5~6%, diethylene glycol 0.3
~5%.It is but above-mentioned in the prior art using triethanolamine as raising of the grinding aid of primary raw material to the activity index of slag
Effect is not obvious, and cost is higher, therefore, is developed extremely urgent for slag grinding aid product with strong points.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of multiple elements design steel slag grinding aid, with the organic core of optimal binary
Composite multi-component component effectively improves the comprehensive performance of grinding.
The invention is realized by the following technical scheme：
Multiple elements design steel slag grinding aid, including following parts by weight component：Triisopropanolamine presses 1~3 with glycerine：3~1 are configured to
Binary core component, then multiple elements design grinding aid is configured to triethanolamine, polyoxyethylene stearic acid ester, calcium lignosulfonate, deionized water,
Wherein 30~50 parts of binary core component, 8~12 parts of triethanolamine, 5~10 parts of stearic acid polyoxyethylene fat, 4~8 parts of calcium lignosulfonate,
15~30 parts of deionized water.
The present invention is further improved scheme, and triisopropanolamine presses 1 with glycerine：1 is configured to binary core component.
Further improvement project of the invention is multiple elements design grinding aid wherein 50 parts of binary core component, triethanolamine
10 parts, 5 parts of stearic acid polyoxyethylene fat, 5 parts of calcium lignosulfonate, 30 parts of deionized water.
Further improvement project of the invention is that the polyoxyethylene stearic acid ester is polyoxyethylene stearic acid ester PEG6.
Compared with prior art, the present invention with following obvious advantage：
0.1% present invention of total weight, 80 mesh screen residue rates, specific surface area, the particle diameter distribution of slag after grinding are added in steel-making slag powder
Comprehensive performance it is excellent.
Specific embodiment
First, the organic core component embodiment screening of binary
1st, 100 í, 100 small ep ball milling instrument is taken in experiment, and each steel slag grinding amount is 400g, and grinding aid volume is slag weight
0.1%, binary grinding aid is according to 1：1 proportioning, does three groups of experiments, passes through 80 mesh screen residues, specific surface area, particle diameter distribution, glue respectively
Sand pi of strength finds optimal binary core component.
