Abstract
The invention relates to a ready-mixed mortar super-retarder, which is characterized by being composed of the following components by weight percentage: 10-20% of calcium lignosulphonate, 10-20% of sodium gluconate, 25-45% of white sugar, 1-3% of antiseptic germicide and 30-50% of water, wherein the components are polymerized to form a particular-structure synthetic product in the environment of 30-50 DEG C. After synthesis is finished, purification processes of slag removing, ammonia removing, chlorine removing, and the like are carried out, and a final product is formed after PH adjustment. The ready-mixed mortar super-retarder has the characteristics of high stability, wide cement adaptability, high water-reducing rate, good environment-friendly performance, and the like, and can significantly improve the workability and water retention of mortar and each physical and mechanical property of the mortar after hardening. The low ammonia emission amount and the zero formaldehyde content can not pollute environment, and the ready-mixed mortar super-retarder is especially suitable for super retarding and keeping density of ready-mixed commercial mortar in the summer high-temperature season.
Description
Technical field
The present invention relates to a kind of mortar retardant, it belongs to the type material scientific domain, is specially adapted to the super slow setting and the guarantor of summer high-temperature premixing commodity mortar during season 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.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.
In actual applications, particularly at high temperature season temperature on average more than 37 ℃ the time, can shorten the time of coagulation of mortar, sometimes even the micropetrosis phenomenon can occur, influenced construction speed and quality.
Summary of the invention
Because of in the mortar construction process, such as piling up, its construction process is long, and particularly at summer high-temperature during season, the serviceability of mortar becomes very poor.In order to solve this contradiction and to remedy the defective that prior art exists, special invention is a kind of is used for prolonging the mortar super-retarder of time of coagulation for we, uses timeliness thereby prolong it.Discover through test of long duration, can be with sulfonated lignin and Sunmorl N 60S Application of composite at the slow setting of admixture aspect the time, thus can prolong working hour of mortar greatly.Thus, we are with this product called after MS-II ready-mixed mortar super-retarder.
Know-why of the present invention: ready-mixed mortar super-retarder is that calcium lignin sulphonate and Sunmorl N 60S are carried out purifying treatment, with isothiazolinone anticorrosion and bactericidal agent (commercially available TF-02 anticorrosion and bactericidal agent) serves as to trigger agent, in 30 ℃-50 ℃ environment, carry out compound, thereby form the synthetic product of ad hoc structure.After the compound end, further carry out high speed centrifugation and go precipitation slagging-off, remove ammonia at normal temperatures, fall purification process such as chlorine, at last through potential of hydrogen adjustment formation product.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 premixing mortar retardant 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 25%-45%
Isothiazolinone anticorrosion and bactericidal agent (commercially available TF-02 anticorrosion and bactericidal agent) 1%-3%
Water 30%-50%
Described ready-mixed mortar super-retarder preparation method comprises following step:
(1) water in the described constituent is warmed up to 30-50 ℃, drops into calcium lignin sulphonate while stirring, high speed centrifugation went precipitation after dissolving was finished, and changed in the reactor.
(2) start stirrer, be warming up to about 35 ℃, keep temperature, drop into Sunmorl N 60S and white sugar while stirring successively, keep temperature to stir 30 minutes, begin to drip isothiazolinone anticorrosion and bactericidal agent (commercially available TF-02 anticorrosion and bactericidal agent), dropping remains a constant speed, dropwise about 30 minutes, continued insulated and stirred 30 minutes.
(3) treat that step (2) stirs insulation, behind the naturally cooling, carry out high speed centrifugation once more and go the precipitation slagging-off, remove ammonia at normal temperatures, fall chlorine, and adjust the pH value about 6-8, be finished product.
Advantage of the present invention: described ready-mixed mortar super-retarder, volume scope are at 08%-1.8%, and slow setting is characteristics of its maximum, and it can obviously improve the every physical and mechanical property behind workability, water-retentivity and the mortar hardening of mortar.In encloses container, can keep 28 hours noncondensing, surpass 28 hours or after mortar moisture is adsorbed evaporation, mortar still can setting and harden, is particularly suitable for doing premixing mortar and uses when summer high-temperature.Simultaneously, this product has certain water-reduction, is recommending 1.5% time water-reducing rate of volume to reach more than 12%.Along with the increasing of volume, slurry consistency increases gradually, and delamination degree reduces gradually, and the stability and the consistence of mortar improve gradually.This product has well satisfied the requirement under following two different states: can keep long time of coagulation under the hot weather preservation state, to guarantee mortar validity at the appointed time; After construction, can harden faster, thereby can not influence the normal construction progress.
Technical indicator of the present invention: described ready-mixed mortar super-retarder is on the basis that meets DG/TJ08-502-2000 " premixing mortar production and utilisation technology rules " standard, at aspects such as product stability, adaptability, water-reducing rate, environmental-protecting performance, economy, particularly than conventional products large increase has been arranged aspect time of coagulation at mortar.
Effect of the present invention: from the present invention's exploitation so far, in multinomial Important Project, be applied.Product of the present invention 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.Admixture the premixing mortar of ready-mixed mortar super-retarder to a certain degree improvement is all arranged 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.
