Abstract
The invention relates to the technical field of a cement additive, and particularly relates to a large-mixing-amount limestone grinding aid. The large-mixing-amount limestone grinding aid is prepared from the following raw materials in percentage by weight: 18-25 percent of an alkanolamine compound, 1-5 percent of water retaining cellulose, 5-10 percent of ethyl maltol, 5-10 percent of sodium aliphatate, 10-15 percent of polystyrene, 2-7 percent of sodium pyrophosphate, 0.5-2 percent of polytetrafluoroethylene, 0.1-0.7 percent of sodium gluconate, 3-7 percent of saccharides, 1-5 percent of xanthan gum and the balance of water. During cement grinding, by adopting the grinding aid disclosed by the invention, the mixing amount of limestone in the cement can be greatly increased to 30%, amount of used clinkers is reduced, the cost is lowered and the strength of the cement is not affected.
Description
Technical field
The present invention relates to cement additive technical field, particularly a kind of large dosage Wingdale 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 the industry of national developmental limitation.National requirements, when maintaining current production capacity and being constant, energy consumption declines 5% every year, and this saves energy and reduce the cost energetically with regard to an urgent demand cement industry.The optimal path that cement production enterprise is saved energy and reduce the cost is exploitation or multiplex cement additive, and especially when manufacture of cement, cement production enterprise wishes to use grog less as far as possible, mixes blended material more.But along with the increase year by year of China's cement output, as active mixed material (slag the is main) resource-constrained of first-selection, supply is becoming tight day, the blended material that some activity are lower, as barren rock lime stone, resource is relative abundance then, and it has compared with other mixing materials, and price is low, haul distance is short, the moisture advantage such as less, not ask for help, and the cement production enterprise in cement active mixed material shortage area is wished mostly can more multiplex Wingdale meets production, reduces costs in cement demand.If can utilize by large dosage in cement, the problem of producing the shortage of cement (code name PC) blended material and mine resources comprehensive utilization can be solved well, for cement production enterprise brings good economic benefit and social benefit.
Wingdale is a kind of inertia mixing material, and in manufacture of cement, because the activity of Wingdale is very low, in order to meet the requirement of strength of cement, the volume of Wingdale is general only about 10%.The reinforced effects of existing cement grinding aid to Wingdale is not obvious, does not realize the object that large dosage in manufacture of cement utilizes Wingdale.For this reason, the volume how improving Wingdale in cement becomes the study hotspot of this area.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of large dosage Wingdale grinding aid, after using grinding aid of the present invention, can to increase substantially in cement the blending amount of mixture material such as Wingdale, reduce clinker dosage, reduce production cost.
For achieving the above object, the present invention adopts following technical scheme:
A kind of large dosage Wingdale grinding aid, be made up of the raw material of following weight percent:
Triacontanol amine compound of the present invention is trolamine, tri-isopropanolamine, di-alcohol monoisopropanolamine, the mixing of one or more arbitrary proportions of diisopropyl ethanolamine.
Water conservation Mierocrystalline cellulose of the present invention is the one in methylcellulose gum, Vltra tears, hydroxyethylmethyl-cellulose.
Preferably, triacontanol amine compound of the present invention is tri-isopropanolamine.
Carbohydrate of the present invention is the one in sugared calcium, sucrose, molasses.
The particle diameter of tetrafluoroethylene of the present invention is 1 ~ 3 μm.
In the raw material of the present invention's formula, not only containing amino but also containing hydroxyl in alcamine compound molecule, there is the over-all properties of amine and alcohol, as tensio-active agent, there is good dispersiveness, also as hardening accelerator, improve the early strength of cement; Water conservation Mierocrystalline cellulose is effective water conservation in cement, along with aquation carries out slow releasing portion of water, for the aquation of cement provides water source, compensate for shrinkage is had long-lasting, significantly improve cement initial value stability, the cement later stage shrinks and obviously reduces, and controls cement and shrinks far below Critical Cracking deformation values; Veltol plus and sodium soap improve early anaphase intensity; Polystyrene has the formation of filling, blocking pore seam, and cut off pore seam, macropore is diminished, overall porosity reduces, and ensures the intensity of cement; The dispersion effect of trisodium phosphate to Wingdale is remarkable; The particulate matter of the water insoluble and alcohol of tetrafluoroethylene, intensity is higher, can filling concrete space, effectively improve cement early anaphase intensity, and it has superpower lubrication; Sunmorl N 60S contributes to the mobility improving cement, improves mill efficiency; Carbohydrate adds the loading level that can significantly improve Wingdale, increases substantially Wingdale incorporation in cement; Xanthan gum can ensure the permanent stability of grinding aid, ensures the performance of cement, can prevent the precipitation of crystal simultaneously, affect the quality of cement.
Beneficial effect of the present invention is:
1, each raw material synergy in grinding aid of the present invention, can not only increase substantially Wingdale incorporation in cement, in cement composition, the volume of Wingdale is increased to 30%, reduces the consumption of grog, reduces costs.
2, the present invention can either improve the incorporation of Wingdale, also 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 greatly reduces the cost of cement.
