Abstract
The invention relates to a special retarder of ready-mixed mortar, which is characterized by comprising the following components by weight percent: 10 to 20 percent of calcium lignosulphonate, 10 to 20 percent of sodium gluconate, 20 to 40 percent of white sugar, 1 to 3 percent of isothiazolinone anti-corrosion mildewproof bactericide and 30 to 50 percent of water. The components are compounded in an environment of 30 to 50 DEG C to form a synthetic product with a specific structure. After the synthesis is finished, the purification processes of slag removal, ammonia removal, chlorine degradation and the like are carried out, and a final product is formed after pH value regulation. The product has the characteristics of higher stability, extensive cement adaptability, higher water-reducing rate, good environmental-protection performance and the like, is an environmental-protection product and can not cause pollution to the environment because of very low ammonia release quantity and zero formaldehyde content.
Description
Technical field
The present invention relates to a kind of mortar special retarder, it belongs to the type material scientific domain, and the slow setting that is specially adapted to the premixing commodity mortar is protected thick.
Background technology
Building mortar is requisite a kind of main raw material(s) in the construction work.Different according to application site and function, building mortar has a large amount in variety, as levelling, build by laying bricks or stones, plaster, repairing, filleting, waterproof etc.Wherein levelling, build by laying bricks or stones and these three kinds of building mortars of plastering have accounted for significant proportion in all building mortars.System is mixed at how employing of domestic construction mortar scene at present, and there are a lot of defectives such as construction intensity is big, recruitment is many, quality stability is poor, the system contaminate environment is mixed at the scene, the stirring noise is big in this compound method.
Summary of the invention
Because in the mortar construction process, such as piling up, its construction process is long.In order to solve this contradiction and to remedy the defective that prior art exists, special invention is a kind of to be used for prolonging the mortar special retarder of time of coagulation, uses timeliness thereby prolong it.Through test of long duration research, discovery can be applied in calcium lignin sulphonate and Sunmorl N 60S the slow setting time aspect of admixture, after increasing calcium lignin sulphonate simultaneously, the denseness of mortar and delamination degree can obviously be improved, thereby can improve the serviceability of mortar greatly, we are with this product called after MS-I special retarder of ready-mixed mortar.
Know-why of the present invention: special retarder of ready-mixed mortar is that calcium lignin sulphonate and Sunmorl N 60S are carried out purifying treatment, with the anticorrosion antimildew disinfectant of isothiazolinone (commercially available) is exciting agent, in 30 ℃-50 ℃ environment, carry out compound, thereby form the product of ad hoc structure.After the compound end, further remove the gred, remove ammonia, fall purification process such as chlorine, form product through the potential of hydrogen adjustment at last.Product has advantages of higher stability, cement adaptability, and water-reducing rate is higher, characteristics such as environmental protection.
Technical scheme of the present invention is: described special retarder of ready-mixed mortar is characterized in that being made up of following constituent and weight percent:
Calcium lignin sulphonate 10%-20%
Sunmorl N 60S 10%-20%
White sugar 20%-40%
The anticorrosion antimildew disinfectant 1%-3% of isothiazolinone
Water 30%-50%
Described special retarder of ready-mixed mortar preparation method comprises following step:
(1) water in the described constituent is warmed up to about 30 ℃, keeps temperature, drop into calcium lignin sulphonate while stirring, keep temperature to stir 30 minutes, high speed centrifugation went precipitation after dissolving was finished, and changed in the reactor again.
(2) start stirrer, be warming up to about 45 ℃, keep temperature, after dropping into Sunmorl N 60S and white sugar successively while stirring, keep temperature to stir 30 minutes, begin to drip the anticorrosion antimildew disinfectant of isothiazolinone, the dropping that remains a constant speed dropwised about 30 minutes, continued insulated and stirred 30 minutes.
(3) treat step (2) naturally cooling after, carry out high speed centrifugation once more and go precipitation (slagging-off), removes ammonia at normal temperatures, falls chlorine, and adjustment pH value is finished product about 6-8.
Advantage of the present invention: special retarder of ready-mixed mortar, volume 1.0%-2.0%, it can obviously improve the workability of mortar, every physical and mechanical property behind water-retentivity and the mortar hardening, in encloses container, can keep 24 hours noncondensing, surpass 24 hours or after mortar moisture is adsorbed evaporation, mortar still can setting and harden, this product has certain water-reduction simultaneously, water-reducing rate can reach more than 12% under the volume recommending, increasing along with volume, slurry consistency increases gradually, delamination degree reduces gradually, the stability and the consistence of mortar improve gradually, and this product has well satisfied the requirement under following two different states: the time of coagulation that can keep growing under preservation state is to guarantee mortar validity at the appointed time; Thereby after construction, can harden the unlikely normal construction progress that influences faster.
Technical indicator of the present invention: this product special retarder of ready-mixed mortar is meeting that DG/TJ 08-502-200610012-2006 commodity mortar is produced and the utilisation technology rules " on the basis of standard, at aspects such as product stability, adaptability, water-reducing rate, environmental-protecting performance, economy, large increase has been arranged than conventional products.
Effect of the present invention: from the present invention's exploitation so far, in multinomial Important Project, be applied.This product can reach premixing mortar fully to the requirement of time of coagulation, again can sclerosis in the short period of time after construction, guarantee job schedule.The premixing mortar of admixture special retarder of ready-mixed mortar all has improvement to a certain degree at aspects such as stability and operability, the water-reducing rate of this product 12% can help the premixing commodity mortar to reach design strength, reduces production costs.This product is a kind of environmentfriendly products, and ammonia burst size that it is extremely low and zero formaldehyde content can not pollute environment.
