Description
Technical field
The present invention relates to a kind of injecting paste material, particularly relate to the ultra-fine anti-segregation injecting paste material of a kind of environment-friendly type for slip casing by pressure.
Background technology
Traditional coal mine lane water blockoff, consolidation grouting material mostly select cement plasmoid material to coordinate slip casting with water glass, major cause cost is low, wide material sources, because after cement-silicate sclerosis, volumetric shrinkage produces crack, later stage is owing to producing the reaction of chemical sodium ion after cement-silicate aquation, sodium is the structure directly destroying petrifying water mudstone, to cause secondary to appear again the phenomenon of water polluted underground water source.From the beginning of the seventies, the U.S., Japan have prohibited and have used water glass slip casting, and organic materials is as very difficult in poly-rare acid amides, xylogen slip casting single performance material solve water filling, and organic injecting paste material poor durability, poisonous, can to environment, its cost is also high.
At present, the production and application unit of the inorganic injecting paste material of China is a lot, but all adopts in cement and mix slip casting agent to use, formula mainly water reducer, retardant and the fine mineral carrier etc. of its slip casting agent.In extemporaneous preparation injecting paste material process, the easy conglomeration of fine mineral carrier, is difficult to stir, does not reach expected effect, and the phenomenon such as precipitation, segregation, bleeding easily appears in injecting paste material slurry, is unfavorable for carrying out smoothly of slip casting operation; The flowing property of slip casting slurry is difficult to the requirement meeting grouting process, shows as degree of mobilization gradual loss large; For controlling fluidity loss, usually adopting and super mixing slow setting component to realize, having occurred so again slip casting slurry extra retarded set phenomenon, what do not have slip casting should be effective; Because water-cement ratio is large, slurry significant shrinkage, does not have the effect of slip casting shutoff.
Therefore, a kind of both there is superior workability if can obtain, have again good erosion resistance and weather resistance, later strength, less than the ultra-fine anti-segregation injecting paste material of multi-functional, the adjustable type of contracting and self micro-expansibility, will provide reliably quality-guarantee for slip casting industry.

Introduce carboxyl in the sulfamate based water reducer molecule of carboxy-containing acid group, improve molecular structure (introducing side chain), improve degree of mobilization and the degree of mobilization retentivity of slurry, and with the super-composite effect of naphthalene series high-efficiency water-reducing agent.The preparation method of comparative example 2 is with embodiment 2, and difference is not add above-mentioned two kinds of water reducers.
Tripoly phosphate sodium STPP and Sunmorl N 60S compound use are to improving the degree of mobilization of slurry and improving degree of mobilization gradual loss and serve super-composite effect.The preparation method of comparative example 3 is with embodiment 2, and difference is not add tripoly phosphate sodium STPP and Sunmorl N 60S.
Vltra tears plays the anti-eduction of water-keeping thickening.The preparation method of comparative example 4 is with embodiment 2, and difference is not add Vltra tears.
Sodium bicarbonate is improving the degree of mobilization of slurry as buffer reagent and is improving in degree of mobilization gradual loss process and serve synergistic effect.The preparation method of comparative example 5 is with embodiment 2, and difference is not add sodium bicarbonate.
The injecting paste material assay that above-mentioned comparative example obtains is as shown in table 2.
The injecting paste material assay that table 2 comparative example obtains
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
