Abstract
The invention relates to superfine high-temperature-resistant cement and a preparation method thereof, belonging to the technical field of preparation of high-temperature-resistant cement. The superfine high-temperature-resistant cement comprises the following components in parts by weight: 50-90 parts of limestone, 40-80 parts of clay, 30-70 parts of gypsum, 5-15 parts of aluminum oxide, 10-40 parts of superfine CA and 10-40 parts of superfine C2AS. The preparation method comprises the steps of weighing the raw materials in parts by weight, finely grinding, sieving by virtue of a 800-1600-mesh sieve, then feeding into a cement kiln, calcining at 800-1500 DEG C to produce clinkers, and further finely grinding to obtain the superfine high-temperature-resistant cement.

Description
Technical field
The present invention relates to a kind of cement and preparation method thereof, be specifically related to a kind of ultra-fine high temperature resistant cement and preparation method thereof, belong to high temperature resistant cement preparing technical field.
Background technology
Cement and cement-base composite material develop into has become the artificial material that consumption is maximum in the world today.Since the nineties in 20th century, China's cement output leapt to No. 1 in the world, keep growth momentum at a high speed always, occupied first place in the world for years.National cement output 7.3 hundred million t in 2002, within 2003, reach 7.5 hundred million t, and 2006 annual production has reached 12.36 hundred million t, and close to the estimate of 2010, therefore cement remained 21 century main material of construction.Along with the development of society, higher requirement be it is also proposed to the performance of cement, therefore improve the performance of cement, enable to meet multi-functional, the high performance requirement of modern construction engineering to cement; Adopt new method, the new means more cement type of manufacture and exploit energetically; Obtain by the compound between different series cement the gelling material that some has property, be not only the needs of national economy rapid development, whole Cement industry continues flourish prime mover especially.
The development of China's special cement roughly experienced by imitation, autonomous research and development, promotes 3 stages, and through the effort of 50 years several generations, the large class of 6 large systems 8 of having succeeded in developing more than totally 60 plants special cement.At present, China is in the theoretical investigation of special cement, kind quantity and the application level Shang Yijin people world rank of advanced units, meet the needs of the industry such as China's oil water power, chemical metallurgy, building machinery, traffic and ocean exploitation, wherein count ten achievements and obtain national level and ministerial level prize or national inventing patent.
High temperature resistant cement, refractoriness is not less than the cement of 1580 DEG C.Aluminous refractory cement, low calcium-aluminate refractory cements, calcium Mg aluminate cement and rhombspar refractory cements etc. can be divided into by composition difference.Historical summary shows, and along with people are to the discovery of calcium aluminate resistance toheat and understanding, the output of the calcium aluminate in Europe in 1913 there has been raising at full speed.When the twenties in 20th century, indefinite form refractory casting material started the developing steps stepping oneself, to 20th century late nineteen eighties and the nineties, engender new placingJi Shu.Introducing and employment is pumping and the gravity flow pouring technology of Low Cement Castable at first.Afterwards, wet type spray or spraying technique have been there is again.In the change of these technology, create refractory cements.Refractory cements is also aluminate cement.Aluminate cement is with bauxitic clay and Wingdale for raw material, take calcium aluminate as the grog of main component, alumina content about 50% through calcining obtained, the hydraulic cementing materials made of regrinding.Aluminate cement Chang Weihuang or brown, also have grizzly.The essential mineral of aluminate cement becomes monocalcium aluminate CaOAl
2o
3, write a Chinese character in simplified form CA) and other aluminate, and a small amount of Dicalcium Phosphate (Feed Grade) (2CaOSiO2) etc.
Chinese invention: 201310733606.1; Disclose a kind of method of preparation and use of high temperature resistant cement retardant, by accounting for the 2-acrylamide-2-methylpro panesulfonic acid of monomer total mass 40 ~ 60%, the methylene-succinic acid of 20 ~ 40% and the toxilic acid of 10 ~ 20%, to be dissolved in quality be in the water of monomer total mass 2 ~ 4 times, deoxygenation, add the initiator ammonium persulfate accounting for monomer total mass 1.5 ~ 3%, 3 ~ 6h is reacted under 75 ~ 100 DEG C of conditions, then be cooled to room temperature, obtain described high temperature resistant cement retardant.The method is a kind of cement setting retarder of preparation, is not cement material, also needs further technical finesse.Therefore develop a kind of ultra-fine high temperature resistant cement and preparation method thereof tool to be of great significance.
