Abstract
The present invention relates to cement additive technical field, particularly to a kind of large dosage limestone grinding aid, be made up of the raw material of following percentage by weight: triacontanol amine compound 18～25%, water conservation cellulose 1～5%, ethylmaltol 5～10%, sodium soap 5～10%, polystyrene 10～15%, sodium pyrophosphate 2～7%, politef 0.5～2%, sodium gluconate 0.1～0.7%, saccharide 3～7%, xanthan gum 1～5%, water surplus.In cement grinding, use the grinding aid of the present invention, it is possible to increase substantially limestone incorporation in cement and, to 30%, reduce the consumption of grog, reduce cost, do not affect the intensity of cement.
Description
Technical field
The present invention relates to cement additive technical field, particularly to a kind of large dosage limestone grinding aid.
Background technology
Along with deepening constantly of national industrial policies, cement has been classified as emphasis energy consumption industry, is also listed in country's restriction and sends out
The industry of exhibition.National requirements, in the case of maintaining current production capacity constant, energy resource consumption declines 5% every year, and this is with regard to an urgent demand
Cement industry is saved energy and reduce the cost energetically.The optimal path that cement production enterprise is saved energy and reduce the cost is exploitation or multiplex cement mixture
Material, especially when manufacture of cement, cement production enterprise is wished less with grog, many blending conjunction materials.However as China's cement output
Increase year by year, as first-selected active mixed material (slag is main) resource-constrained, supply is becoming tight day, and some activity are relatively low
Mixing material, such as barren rock lime stone, resource then relative abundance, it has compared with other mixing materials, and price is low, haul distance is short, aqueous less,
The advantage such as not asking for help, the cement production enterprise in cement active mixed material shortage area wishes to more multiplex Calx in cement mostly
Stone meets production, reduces the demand of cost.If able to large dosage utilizes in cement, can solve well to produce cement
(code name P C) mixing material shortage and the problem of mine resources comprehensive utilization, bring good economic benefit and society for cement production enterprise
Can benefit.
Limestone is a kind of inertia mixing material, in manufacture of cement, owing to the activity of limestone is the lowest, in order to meet water
The requirement of mud intensity, the volume of limestone is general only about 10%.The existing cement grinding aid reinforced effects to limestone
Inconspicuous, it is achieved in manufacture of cement, large dosage does not utilizes the purpose of limestone.To this end, how to improve limestone in cement
Volume become the study hotspot of this area.
Summary of the invention
The technical problem to be solved is to provide a kind of large dosage limestone grinding aid, uses the grinding aid of the present invention
After agent, the blending amount of mixture material such as limestone can be increased substantially in cement, reduce clinker dosage, reduce production cost.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of large dosage limestone grinding aid, is made up of the raw material of following percentage by weight:
The triacontanol amine compound of the present invention is triethanolamine, triisopropanolamine, diethanol monoisopropanolamine, diisopropyl second
One or more arbitrary proportions of hydramine mix.
The water conservation cellulose of the present invention is in methylcellulose, hydroxypropyl methyl cellulose, hydroxyethylmethyl-cellulose
A kind of.
Preferably, the triacontanol amine compound of the present invention is triisopropanolamine.
The saccharide of the present invention is the one in sugar calcium, sucrose, molasses.
The particle diameter of the politef of the present invention is 1～3 μm.
In the raw material of inventive formulation, alcamine compound molecule not only contains amino but also containing hydroxyl, have amine and alcohol
Combination property, as surfactant, there is good dispersibility, also as early strength agent, improve cement early strength；Protect
Water cellulose element effective water conservation in cement, slowly discharges portion of water along with aquation, and the aquation for cement provides water source, makes
Compensate contraction and have long-lasting, hence it is evident that improving cement initial value stability, the contraction of cement later stage is obviously reduced, control cement and receive
Contracting is far below Critical Cracking deformation values；Ethylmaltol and sodium soap improve early anaphase intensity；Polystyrene has filling, blocks up
The formation of plug capillary slit, cuts off capillary slit, makes macropore diminish, and overall porosity reduces, it is ensured that the intensity of cement；Sodium pyrophosphate
Notable to the dispersion effect of limestone；The water insoluble particulate matter with alcohol of politef, intensity is higher, can be empty with filling concrete
Gap, is effectively improved cement early anaphase intensity, and it has superpower lubrication；Sodium gluconate is favorably improved the stream of cement
Dynamic property, improves mill efficiency；Saccharide adds the loading that can significantly improve limestone, increases substantially limestone in cement and mixes
Enter amount；Xanthan gum ensure that the long-time stability of grinding aid, it is ensured that the performance of cement, is possible to prevent the precipitation of crystal simultaneously,
Affect the quality of cement.
The beneficial effects of the present invention is:
1, each raw material synergism in the grinding aid of the present invention, can not only increase substantially limestone in cement and mix
Amount, in cement composition, the volume of limestone improves to 30%, reduces the consumption of grog, reduces cost.
2, the present invention can either improve the incorporation of limestone, the most slightly improves the intensity of cement simultaneously.
3, limestone resource enriches, and raw material is easy to get, and it is cheap, and its incorporation improves, and is substantially reduced the one-tenth of cement
This.
