Description
Technical field
The present invention relates to slag additive technical field, more particularly to a kind of macromolecule/Small molecular surfactant compounding
Slag grinding aid and preparation method thereof.
Background technology
Slag powders are the abbreviations of ground granulated blast furnace slag, are a kind of concrete admixtures of high-quality, by meeting GB/T203
The granulated blast-furnace slag of standard, through drying, grinding, reaches suitable fineness and meets the powder of suitable activity index, also known as ore deposit
Powder, ground granulated blast furnace slag, the slag micropowder of high-quality is the concrete admixture and cement mixture of high-quality, is the world today
The important materials of generally acknowledged preparation high performance concrete.With the more and more high-end change of China's construction market, internationalization, to high activity
The demand of the slag micropowder of high-quality rises year by year, but is limited by the limitation of technology, S105 grades, S95 grades etc. it is high-grade
The occupation rate of market of slag micropowder is relatively low, does not meet architecture production needs.
Because vitreum content is more in slag micropowder, grindability is poor, and the energy consumption produced by being milled to regulation fineness is high,
And result of the test shows that the specific surface area of slag reaches 480m2/kg or so, most of particle size distributions between 2-40 μm,
Its potential activity could be ejected completely.In order to produce high-specific surface area, low energy consumption slag micropowder, in process of production
The mode of some chemical grinding aids is often added to improve micro mist specific surface area, improve powder characteristic.If any researcher in slag powders
The flyash grinding aid of addition 10% or so while mill, the result is that mill output increases, slag micropowder activity but declines,
Its potential activity performance is not played but completely, and obtained slag micropowder can only mix cement and just can guarantee that original below 15%
The intensity index of cement is not reduced；Some researchers are then modified processing using some chemical activators, also obtain activity
Preferable product, for example《The experimental study of triethanolamine system slag composite grinding aid》One text is using triethanolamine as main component
Grinding aid, mixes progress grinding with slag after coordinating carboxylic acid, inorganic salts and alcohol compound compounding, effectively improves slag
The size distribution and granule-morphology of micro mist, activity index is improved, but triethanolamine is expensive, and its high-temperature volatile
By force, unavoidable affected by temperature in grinding process, popularization and application are restricted.
The content of the invention
There is provided a kind of macromolecule/small molecule table for the defect that makes up existing triethanolamine system slag grinding aid by the present invention
Slag grinding aid of face activating agent compounding and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of slag grinding aid of macromolecule/Small molecular surfactant compounding, the grinding aid by following parts by weight component group
Into：High molecular surfactant 1%-5%, Small molecular surfactant 0.5%-2%, Carbonaceous mesophase 0.1%-0.5%, chelating agent
1%-5%, defoamer 0.1-0.2%, balance of solvent.
Described high molecular surfactant is cationic acrylate copolymer, quaterized polyacrylamide, lignin
One or more in sulfonate, polyacrylic acid and its copolymer, acrylic acid copolymer-maleic anhydride.
Described Small molecular surfactant is neopelex, lauryl sodium sulfate, dodecyl front three
One or more in base ammonium bromide, polyethylene glycol 400, Macrogol 600, polyethylene glycol-800.
Described Carbonaceous mesophase is that one kind in asphalt, carbobitumen, coal tar, catalytic cracking clarified oil exists
400-450 DEG C, the microballoon that the particle diameter prepared through thermal polycondensation process or emulsion method under atmosphere of inert gases is 1-10 μm.
Described chelating agent be inositol hexaphosphate, low molecular weight sodium polyacrylate, sodium tripolyphosphate, calgon,
One or more in sodium phytate.
Described solvent is water.
A kind of preparation method for preparing described slag grinding aid, is concretely comprised the following steps：Solvent, macromolecule surface are lived successively
Property agent, Small molecular surfactant, chelating agent put into successively in reaction vessel, fully dissolving adds carbonaceous after being uniformly mixed
Interphase, defoamer, sonic oscillation are produced after disperseing 30-50min.
Grinding aid prepared by the present invention is by high molecular surfactant and Small molecular surfactant compounding use, macromolecule
Hydrophilic group in surfactant, hydrophobic base location size is adjustable, and molecular structure can again can be in branched chain, to micro mist in pectination
Scattered, surface covering and encapsulating effect are stronger, and emulsion stability is strong, and Small molecular surfactant has excellent permeability
With the ability of reduction surface tension, both compounding uses have more preferably than traditional polyalcohol aminated compounds such as triethanolamine
Infiltration, lubrication, grinding-aid effect, then coordinate the use of chelating agent, it is further to promote slag reactivity to excite and refine, while right
Micro mist has certain astriction, it is to avoid granularity is meticulous and causes to reunite seriously；In addition the Carbonaceous mesophase added in raw material is micro-
Ball has drop mill lubrication, can have good change to the pattern of micro mist in mineral surfaces formation lubricating film in process of lapping
Kind effect, obtained slag micropowder pattern is more preferably；Grinding aid environmental protection prepared by the present invention is inexpensive, and performance is stable, easy to use.
