Abstract
The invention relates to a liquid non-chloride compound cement grinding aid and a method for preparing the grinding aid. The grinding aid mainly comprises polyacrylamide, sodium sulfocyanate, triethanolamine, sodium acetate, triisopropanolamine, poly carboxylic acid accessory ingredients and water and is not only provided with the advantages of favorable grinding quality, containing no chloridion, not affecting the service life of the concrete, but also the grinding aid can effectively enhance the enhancement effect of the cement and can improve the usability of the concrete. When the adulteration amount of the grinding aid added into the pulverizing cement is 0.1%, that is, the output of the grinder can be increased by more than 10%, the power consumption can be saved by more than 10%, the cement strength can be increased by 3-6MPa within 3days and 4-8MPa within 28days under the same conditions, cement clinker can be saved by 10%, the amount of the multiple-purpose industrial residue can be increased by 10%, the production cost of the cement per ton can be reduced.
Description
Technical field: the invention belongs to the cement grinding technical field.Relate to a kind of liquid non-chlorate cement grinding aid and preparation method, this grinding aid is mainly used in cement production.
Technical background: China is the first in the world manufacture of cement big country.Cement output accounts for half of world's cement total amount, and the root problem of Cement industry is resource problem, energy problem, environmental protection problem.The cement additive technology plays an important role for the problem that solves the Cement industry existence.World's cement output on average has 60% product use cement grinding aid at present, and developed country's usage quantity reaches more than 85%, and only there is 20% cement use grinding aid in China.The cement grinding aid of China's use at present has two kinds, and a kind of is the solid grinding aid, and the incorporation in cement is 0.5%～1.0%, accounts for about 90% of China's cement grinding aid total amount.Powder grinding aid generally contains a large amount of chlorions, easily causes steel bar corrosion, and is harmful to the cement concrete weather resistance.A kind of is liquid grinding aid, volume is 0.2 ‰～0.4 ‰ in cement, account for about 10% of China's cement grinding aid total amount, the advantage of liquid grinding aid is that the grinding aid effect is relatively good, chloride ion-containing not, but strengthen the effect deficiency, therefore the admixture industrial residue has seriously hindered applying of it in a large number.
Summary of the invention: the objective of the invention is for overcoming prior art liquid cement grinding additive product enhancement function deficiency, strengthen the incorporation of industrial residue in cement, promote the energy-saving and emission-reduction of Cement industry, meet the need of market, a kind of grinding-aid effect is good, reinforced effects is better, have the liquid non-chlorine type composite cement grinding aid that improves the cement use properties concurrently and provide.And wherein chloride ion-containing not can not influence concrete work-ing life.
The objective of the invention is to be realized by following technical scheme: the raw material and the mass percent thereof of cement grinding aid of the present invention consist of:
Polyacrylamide 3%～5% Sodium Thiocyanate 99 4%～8%
Trolamine 20%～30% sodium acetate 10%～20%
Tri-isopropanolamine 3%～6% poly carboxylic acid auxiliary agent 10%～30%
Water 30%～45%
Further, the mass percent of each component consists of:
Polyacrylamide 3%～5% Sodium Thiocyanate 99 4%～8%
Trolamine 22%～28% sodium acetate 12%～18%

Water 33%～42%
Further, the mass percent of each component consists of:
Polyacrylamide 3%～5% Sodium Thiocyanate 99 5%～7%
Trolamine 22%～27% sodium acetate 12%～16%
Tri-isopropanolamine 4%～6% poly carboxylic acid auxiliary agent 12%～18%
Water 35%～40%
Above-mentioned its molecular weight of said polyacrylamide is preferably 8,000,000-1,000 ten thousand.
The preparation method of cement grinding aid of the present invention, its processing step is as follows: earlier polyacrylamide is dropped in batches powerful the stirring 30 minutes substantially in 100 ℃ of water, form state of saturation, filtered again and formed the polyacrylamide saturated solution, again this saturated solution is mixed powerful the stirring 30 minutes substantially with other components, to evenly, promptly make product of the present invention.
Liquid non-chlorate cement grinding aid of the present invention addition content in cement when pulverizing cement is 0.1%, can reach and improve mill output more than 10%, save power consumption more than 10%, under equal conditions can improve strength of cement, 3 days raising 3～6MPa, 28 days raising 4～8MPa, can save cement clinker 10%, many with industrial residue 10%, ton cement reduces production costs 10 yuan, and can improve cement performance effectively.One ton of this product uses in the time of can be for 1000 tons of manufacture of cement, and cement per ton can be saved standard coal 14kg, and economize on electricity 10.5kwh reduces consumption of limestone 130kg, reduces clay and consumes 18kg, uses industrial residue 100kg more, and industrial dust 1kg reduces discharging CO
2100kg reduces discharging SO
20.13kg, reduce discharging NO
X0.15kg.This invention is taken a new road to industrialization to Cement industry, realizes energy-saving and emission-reduction, increases economic benefit and has most important significance.
