Description
Technical field
The invention belongs to the field of building materials, are a kind of systems of two-component dyeing hardening sealant floor material specifically
Standby and application method.
Background technique
Concrete is the maximum manufactured construction materials of mankind's usage amount, is widely used in all kinds of Structural Engineerings；But based on mixed
Solidifying soil material itself and construction level limitation, breakage can't bear already for many infrastructure, Industrial Plant Ground etc., and surface is cheated
Dirt, dusting, skin effect phenomenon, are played at weathering in hole, cause to wear no resistance, service life is short, does not adapt to modern production environment
Demand, be badly in need of transformation；Currently, conduct more popular on domestic and international market is to use liquid hardening agent, rigidizer material master
Have two classes: it is main component hardening sealant agent that one kind, which is with Nano silica sol (such as CN201010543000.8), wherein silicon is molten
Glue includes a large amount of silicon oxygen bonds, and the afwillite (C-S-H) for generating and capable of improving concrete abrasion-resistant performance, energy can be reacted with concrete
It is effectively improved and is promoted the performances such as concrete hardness, wearability.Another kind of is lithium base salt product, and this kind of curing agent can be mentioned substantially
The performances such as wear resistance, the glossiness of high concrete, and the common fault for the whiting that product early period limited can be avoided to occur；Such as
CN200910055825 and CN201110083155.2 etc. is disclosed all using lithium base salt as main component, is reacted with concrete
After play humidification, the performances such as compactness, glossiness for being re-introduced into other additives to increase concrete；But its effective component contains
Measure it is lower, single construct brought by concrete performance promoted few, and the gloss durability and weatherability of done product are poor, shorter
Gloss decline is obvious in time.
With being constantly progressive for social science and technology, people gradually discharge the personalization of building ground, diversified demand, start
Gradually pursue not only durable but also beautiful product, the especially diversification of concrete apparent colour, therefore, develop it is a can be big
While width improves concrete items comprehensive performance, and the terrace for being able to satisfy its color diversified demand has become the field instantly
One of the direction of each scientific research personnel's primary study.

Inventive principle description:
The reinforcing effect of two-component dyeing hardening sealant floor material of the present invention is mainly realized by following three kinds of modes:
1, stannic chloride pentahydrate (SnCl4) Nanoparticulate SnO is formed under the adjusting of ammonium hydroxide after hydrolysis2Colloidal sol, and with
It under the action of surfactant is common, penetrates into inside concrete pore, fills up mixed in a manner of tiny particles content reinforced phase
Larger hole in soil is coagulated, compactness is enhanced, it is also to increase coagulation that this reaction, which is most important step during whole system enhances,
One of main reaction of native wearability；
2, the lithium metasilicate solution in component A in concrete hydrated product and unhydrated cement react, generate
The macromolecular of network-like cross-linked structure, more tiny hole keeps it further closely knit in fill concrete；
3, after the enhancing of component A effective component, boehmite (AlOOHnH in B component2O, n=0.08~0.62)
Colloidal sol infiltrates into the superficial layer of concrete under the high speed grinding effect of polishing machine under pressure, and with calcium therein from
Son, which reacts, generates the main enhancing ingredients calcium aluminate of high alumina cement；Meanwhile boundary of works area can be made during high speed grinding
Interior surface temperature may advantageously facilitate the generation of calcium aluminate in this temperature range up to 60~70 ° to seal the part such as surface layer pin hole
Hole, and terrace surface is made to form the closed entirety of approximation；
In addition, being added to inorganic toner in the present invention, it infiltrates into inside concrete, especially can be with Nanoparticulate
SnO2Colloidal sol is tightly combined, on the one hand along with the extension of time, inorganic toner can occur with the metal ion in concrete from
Son exchange is to make concrete form permanent stain；On the other hand, with SnO2Colloidal sol is together with pore in blocking concrete
Form make its colouring, under the collective effect of this two ways, certain thickness dye layer is formed inside mattess, most
Under acting on afterwards by the sealing that surface layer B component is ground, complete fine and close and color controllable, uniform color a terrace is formed.
Therefore, the present invention can be by enhancing concrete after above-mentioned three kinds of mode collective effects, and is completed at the same time incrustation.
Compared with the prior art, the advantages of the present invention are as follows:
(1) two-component dyeing hardening sealant terrace of the present invention is by with stannic chloride pentahydrate (SnCl4), lithium metasilicate solution
And nanoscale boehmite (AlOOHnH2O, n=0.08~0.62) colloidal sol curing agent as main component, can by with
Specific grinding technics is combined closely, and the Novel terrace for integrating dyeing, superhardization and polishing is prepared.
(2) it can be used to prepare complete fine and close and color controllable, uniform color terrace in the present invention, solve different crowd
The problem of to terrace diversity requirements.
(3) material in the present invention is water-based material, and easy construction, directly large area roller coating or can be sprayed into concrete
Surface is constructed, and mattess after processing has the characteristics such as high rigidity, high-wearing feature, high glaze, and gloss is more used
About persistently, surface shows gloss as waxing.
(4) present invention is the Novel terrace product for collecting concrete hardening, dyeing and integrated construction, and preparation process is simple,
Reaction process is easy to control, reaction condition is mild, also non-volatility toxic gas, no pollution to the environment, and raw material letter in reaction
It is single, it is at low cost, it is easy for construction, it is particularly suitable for the construction of large area industrialized production.
