Description
Technical field
The present invention relates to a kind of cement grinding aid, be specifically related to liquid cement grinding additive of a kind of low pure amine content and preparation method thereof.
Background technology
Cement in China output is very big, has become cement first big producing country.Cement production consumption is high, and its grinding process accounts for 2/3rds of total power consumption, and capacity usage ratio is low.Therefore, improving mill efficiency is the energy-saving and cost-reducing key of manufacture of cement.In the cement pulverizing course; When cement granules is accepted extraneous mechanical energy; Outside miniaturization of particle-removing size and specific surface area increase; Also produced a series of variations such as particle surface layer amorphization, lattice imperfection, lattice distortion, surface free energy increase, made particle be in a kind of metastable upper state, material is active to be improved thereby make.Therefore, powder-grinding process be prone to produce phenomenon such as full mill, slimeball, wall built-up, cohesion and influences efficient.Cement grinding aid is to have strong surfactivity and dispersed auxiliary agent, in grinding process, adds cement grinding aid, and then grinding aid is adsorbed on the material particles surface; Make the valence link power on the surface of fracture obtain saturated; Reduced the material surface free energy, agglomeration power between the particle obtains shielding, has prevented the generation of cohesion, slimeball, wall cling phenomenon; Reduce friction, thereby improved the dispersed and mobile mill efficiency that improves of material.Adopt liquid grinding aid generally can improve grinding efficiency 10-30%.The liquid grinding aid consumption is few, and is easy to use, adopted by most cement production enterprises at present.
The representative formula of at present external liquid cement grinding additive is made up of trolamine, tri-isopropanolamine, terepthaloyl moietie, xylogen, urea etc.In the representative formula of domestic liquid cement grinding additive, both also are staple for trolamine, tri-isopropanolamine.The consumption of hydramine is all bigger in these prescriptions, accounts for more than 30%.Trolamine, tri-isopropanolamine are petrochemical materials, and price is influenced greatly by oil, and price is high always at present, cause the grinding aid cost to rise, and influence it and apply.
Summary of the invention
The object of the invention is to provide a kind of dependence that reduces petrochemical material, and the liquid cement grinding additive of the low pure amine content of reduction cement grinding aid production cost and preparation method thereof.
The technical scheme that the present invention adopts is: a kind of liquid cement grinding additive of low pure amine content is characterized in that: mixed by waste molasses, sodium lignosulfonate, sodium formiate, trolamine, sodium alkyl benzene sulfonate, silicone antifoam agent, polycarboxylate water-reducer and water, the mass ratio of said each component is following: waste molasses 18-25%; Sodium lignosulfonate 8-12%; Sodium formiate 5-6%, trolamine 6-10%, tensio-active agent 1-4%; Polycarboxylate water-reducer 8-10%, surplus is a water.
The preparation method of cement grinding aid according to the invention; It is characterized in that: in mixing kettle, add the water of metering, add trolamine, waste molasses, sodium alkyl benzene sulfonate, the silicone antifoam agent of metering in proportion, be stirred to evenly; The sodium formiate, sodium lignosulfonate, the polycarboxylate water-reducer that add metering more successively; Be stirred to whole dissolvings, hold over night, the packing of discharging after the assay was approved promptly gets cement grinding aid.
The present invention rationally utilizes the sugar industry waste molasses, and the adding of waste molasses helps the raising of strength of cement in each in the length of time.Sodium lignosulfonate reclaims acquisition from the paper industry cooking waste liquor, the domestic aboundresources of this material is a kind of outstanding water reducer, and it can significantly improve concrete workability.These raw materials are used to grinding aid make resource obtain reasonable utilization.
Increased an amount of sodium alkyl benzene sulfonate among the present invention, it is a kind of tensio-active agent, helps the dispersion of grinding aid in cement.Be adsorbed onto the sodium alkyl benzene sulfonate on comminuting matter surface; To play a part lubricant being formed the monomolecular adsorption film, reduce sticky between cohesion and subparticle and the liner plate between fine particle by levigated fine particle surface; Reduce intergranular frictional force, improve the flowability of cement powder.Thereby the flow faster of material in mill, improve manufacture of cement efficient.
Therefore use cement grinding aid of the present invention, not only can significantly improve single machine yield, reach energy saving purposes, and each age strength of cement is increased, reduced dependence, and reduce the production cost of cement grinding aid petrochemical material.
The present invention has reduced the dependence to petrochemical material, reduces the cement grinding aid production cost, helps applying; Can significantly improve mill efficiency after the application, put forward the product amplitude and reach 10-20%, cement production enterprise can reach energy saving purposes; Can increase cement flows property, reduce caking phenomenon, reduce and carry cost, cut the waste; Can improve strength of cement, intensity improved 2-3Mpa in three days, and intensity improved 3-5 Mpa in 28 days.
