Abstract
The invention relates to liquid composite grinding aid for granulated blast-furnace slag and a preparation method thereof. The grinding aid is prepared by triethanolamine 1-30 parts, mixed alcohol 15-20 parts, glycerin 5-10 parts, molasses 5-10 parts, sodium acetate 1-10 parts, sodium tripolyphosphate 1-10 parts, sodium sulfate 1-10 parts and water 40-50 parts. The liquid composite grinding aid is low in toxicity, non-volatile, stable in source, sufficient in supply, simple in processing and preparation and low in cost. Can improve distribution and morphology of powder particles after doped into the granulated blast-furnace slag, has no adverse effects on mineral powder quality, has the good advantages of improving the yield and the mineral powder quality, and simultaneously reduces energy consumption greatly. The liquid composite grinding aid is stable in performance, low in price and high in cost performance, wide in adaptability and low in admixture amount, improves the grinding effect, increases specific surface area of the mineral powder and improves activity index of the mineral powder under the condition of same grinding time.
Description
Technical field
The invention belongs to the technical field of GBFS grinding process admixture, be specifically related to a kind of granulated blast-furnace slag liquid composite grinding aids and preparation method thereof.
Background technology
At present, China's iron and steel output is produced 1 ton of pig iron with domestic mean level (ML) and is produced 0.50 ton of slag calculating about 3.5 hundred million tons, and China's slag output is about 1.75 hundred million tons.Therefore, how utilizing the slag solid waste, is for many years problem of research always of Chinese metallargist, also is to develop a circular economy, build a conservation-minded society and a realistic problem that friendly environment society should solve emphatically.The slag great majority are to use as cement mixture for a long time, and with the cement clinker intergrinding, the fineness of slag is weighed general 250m by specific surface area
2Below/the kg, this does not make its potential hydraulically active be not fully exerted, and from the energy and resource view, can say that be huge waste to a kind of precious resources as the adulterant of traditional cement to slag.The slag separate grinding to certain fineness (generally at 400m
2More than/the kg), be incorporated into again in cement and the concrete, can improve significantly the weather resistance of working performance of fresh concrete and maturing.Yet in order to obtain the breeze of larger fineness, often need the long time of grinding, and this can increase energy consumption.Meanwhile along with the prolongation of grinding time, fineness of materials increases gradually, and its specific surface area can also increase, thereby subparticle is assembled mutually, the trend of conglomeration strengthens.After after a while, can be in the homeostasis process of " grinding reunion " in the mill, reach so-called " the grinding limit ".In this state, even prolong again grinding time, material also difficult grinding get thinner, sometimes even make the particle chap.This phenomenon is also not obvious when common grinding, but often occurs in the middle of fine-grinding and superfine pulverizing.One preferably terms of settlement be to add grinding aid.At present both at home and abroad institute's grinding aid majority of study and using is expensive, and the source is short, and volume is bigger than normal, and not obvious to the slag grinding-aid effect, and is little without improvement or improvement effect to slag properties, thereby generally applies and be restricted.
Summary of the invention
The object of the invention is to overcome the prior art above shortcomings, improve by research and development, provide a kind of and can reduce the powder surface free energy, can generally be suitable for again, can improve powder granule and distribute and pattern, increase the liquid slag grinding aid of activity index.
The problem that exists in order to solve prior art, the technical solution used in the present invention is:
A kind of granulated blast-furnace slag liquid composite grinding aids, it is to be made by the raw material of following weight proportioning:
Trolamine 1-30 weight part, mixed pure 15-20 weight part, glycerol 5-10 weight part, molasses 5-10 weight part, sodium-acetate 1-10 weight part, tripoly phosphate sodium STPP 1-10 weight part, sodium sulfate 1-10 weight part, water 40-50 weight part.。
Described a kind of granulated blast-furnace slag liquid composite grinding aids, wherein the weight proportion of each raw material is: trolamine 20 weight parts, mixed pure 18 weight parts, glycerol 7 weight parts, molasses 5 weight parts, sodium-acetate 2 weight parts, tripoly phosphate sodium STPP 1 weight part, sodium sulfate 2 weight parts, water 45 weight parts.
The preparation method of the compound liquid cement grinding additive of described a kind of environment-friendly high-efficiency comprises following step:
1. tripoly phosphate sodium STPP and sodium-acetate are added to the water formation solution, then heat, temperature is heated to 30 ℃;
2. sodium sulfate is joined in the mentioned solution, continue heating, temperature is no more than 50 ℃;
3. respectively trolamine, mixed alcohol, glycerol and molasses are joined in the mentioned solution;
4. this solution is carried out stirring and dissolving, after stirring, cool off, filtering, be finished product.
Advantage and effect that the present invention has are:
A kind of granulated blast-furnace slag liquid of the present invention composite grinding aids is to be composited by modal industrial chemicals and industrial waste, and low toxicity, non-volatile, steady sources, ample supply and prompt delivery, processing preparation are simple, with low cost; Can improve powder granule distribution and pattern after mixing slag, the slag quality is had no adverse effects, have the advantage of carrying preferably product, improving the slag powders quality.Liquid slag grinding aid of the present invention adds in the grinding machine with the volume of 0.04-0.13%, can play and save power consumption, improve mill efficiency, the effect of Effective Raise slag powders specific surface area, growth slag powders activity index.Main body contains industrial residue, environmental protection.
This invention grinding aid adds weight percent in slag be 0.04-0.13%.Granulated blast-furnace slag is put into the ball mill grinding, and the time is 50 minutes, compares with blank sample.
Touchstone is according to GB/T18046-2008 " GBFS that is used for cement and concrete ".Concrete test-results sees Table 1, and table 1 is the breeze testing data.
Table 1 breeze testing data
By testing data as can be known, mix grinding aid after, compare with blank sample, tail over reduction, specific surface area increases, 7 days and activity index raising in 28 days; The breeze rank is brought up to the S105 level from the S95 level.
