Abstract
The invention provides a cement compound type grinding aid which is high-efficient cement grinding aid integrating grinding and enhancement. The cement compound type grinding aid comprises the following compositions in percentage by weight: 10-20% of modified triethanolamine, 10-15% of triethanolamine, 20-30% of triisopropanolamine, 10-15% of glycerinum, 10-15% of sodium humate, 1% of low-molecular-weight fatty salt and 20-30% of clean water. According to the cement compound type grinding aid, the grinding efficiency of a cement grinding technology and the purification of the working environment in a manufacturing shop can be effectively improved, and the cement compound type grinding aid has the characteristics of lowering the production cost and effectively optimizing the properties of cement.
Description
Technical field
The present invention relates to the building materials chemical industry product, relate in particular to a kind of cementitious composite type grinding aid, be specially a kind of cement highly efficient grinding aid that integrates grinding aid and strengthen.
Background technology
Cement is a kind of the most frequently used material of construction, be widely used in engineerings such as civil construction, waterpower, national defence, cement is in the course of processing, need use grinding machine clays into power, according to existing cement grinding process, the grinding phenomenon often appearred in the grinding machine storehouse, produce electrostatic adsorption, and go into to grind the clinker temperature extra-high-speed, even reach 190 degree.Terms of settlement at this situation; usually can add water cement grinding aids; can be composited by trolamine pure chemistry material and industrial waste mostly by commercially available liquid grinding aid; the grinding aid cost is very high; dust from flying in use very easily occurs and worsen production environment; and grinding-aid effect is also not obvious, can influence the performance of cement.
Summary of the invention
Technical problem solved by the invention is to provide a kind of cementitious composite type grinding aid, to solve the shortcoming in the above-mentioned background technology.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of cementitious composite type grinding aid, its component is respectively modified triethanolamine 10 ~ 20%, trolamine 10 ~ 15%, tri-isopropanolamine 20 ~ 30%, glycerine 10 ~ 15%, Sodium salts humic acids 10 ~ 15%, lower molecular weight aliphatic salt 1% and clean water 20 ~ 30% according to weight percent.
Preferably, the weight percentages of components of described cementitious composite type grinding aid is modified triethanolamine 15%, trolamine 10%, tri-isopropanolamine 22%, glycerine 15%, Sodium salts humic acids 10%, lower molecular weight aliphatic salt 1% and clean water 27%.
Cementitious composite type grinding aid based on the said components proportioning, its preparation technology is for earlier joining 22% tri-isopropanolamine in 27% the water, after middling speed stirs, weight percentage is 15% modified triethanolamine, 10% trolamine, 15% glycerine, fully mixes, again 1% lower molecular weight aliphatic salt is added and stir, leave standstill after at last the adding of 10% Sodium salts humic acids being stirred, the filtrate that leaches post precipitation is finished product.
Based on said components proportioning and preparation technology's cementitious composite type grinding aid, its outward appearance is brown liquid, and density is 1.09g/cm
3, pH value about 7.0; The sunlight direct irradiation is avoided in available metal bucket or tank car can, and human body is not had damaging effect.
Beneficial effect:
The present invention can effectively improve the cement grinding process mill efficiency and purify the production plant Working environment, has and can reduce production costs, and effectively optimizes the characteristics of cement performance.
Embodiment
For technique means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, describe the present invention below in conjunction with example.
A kind of cementitious composite type grinding aid, its component is respectively modified triethanolamine 10 ~ 20%, trolamine 10 ~ 15%, tri-isopropanolamine 20 ~ 30%, glycerine 10 ~ 15%, Sodium salts humic acids 10 ~ 15%, lower molecular weight aliphatic salt 1% and clean water 20 ~ 30% according to weight percent.
Embodiment one: the weight percentages of components of described cementitious composite type grinding aid is modified triethanolamine 15%, trolamine 10%, tri-isopropanolamine 22%, glycerine 15%, Sodium salts humic acids 10%, lower molecular weight aliphatic salt 1% and clean water 27%.
After being added in the material based on this set of dispense than the cementitious composite type grinding aid of producing, strength of cement obviously strengthens, and power consumption reduces, and ball mill abrasive dust output improves more than 15%.
Embodiment two: the weight percentages of components of described cementitious composite type grinding aid is modified triethanolamine 17%, trolamine 13%, tri-isopropanolamine 25%, glycerine 10%, Sodium salts humic acids 12%, lower molecular weight aliphatic salt 1% and clean water 22%.
After being added in the material based on this set of dispense than the cementitious composite type grinding aid of producing, strength of cement obviously strengthens, and power consumption reduces, and ball mill abrasive dust output improves 12 ~ 15%
Cementitious composite type grinding aid of the present invention, its principle is to utilize the performance of its various component raw material, absorption on solid particles surface, changed the structural performance of particle surface, reduced the textural property of particle surface, reduce intensity and the hardness of particle, stoped the closure of newborn crackle simultaneously, accelerated the expansion of material crackle.When material is pulverized when being ground to certain fineness, between the particle, can assemble between particle and grinding medium, adhere to and form involucrum.Gathering and the adhesion between particle and particle, particle and grinding medium can promptly be eliminated or weaken to cementitious composite type grinding aid, improves mill efficiency.
More than show and described ultimate principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
