Abstract
The invention discloses a kind of mortar toughener, it is characterized in that: its each components based on weight percentage is: Vltra tears 10 ~ 20%, anion surfactant 10 ~ 20%, cement water reducing agent 20 ~ 60%, fat alcohol polyethylene ether sodium sulfate 0 ~ 20%, OP-100 ~ 20%, air entrapment agent 0 ~ 20%.The present invention is as a kind of hydrophilic surfactant's material, it has the effect of thickening, thickening, dispersion and modification to sand-cement slurry, it not only can reduce the consumption of cement and water, reduce the thermal source of mortar, the temperature being convenient to mortar controls and construction, save building cost, and the mobility of sand-cement slurry, workability, intensity, weather resistance, frost resistance and impermeability can be improved.
Description
Technical field
The present invention relates to that a kind of building is whitewashed, plastered, masonry mortar toughener, belong to material of construction and receive.
Background technology
For buildingly at present to plaster, whitewash, masonry mortar mixes by cement, Sha Heshui.In mixing process, cement particle surface contacts with water and starts to be hydrolyzed and aquation, generate calcium silicate hydrate and calcium hydroxide, and these true tumors are condensed gradually, its cohesive force is much larger than the infiltration power of water to cement granules inside, and these true tumors are condensed into aggregate and are wrapped in around cement granules, and retardance cement granules is hydrolyzed and aquation further, and be only the part that cement particle surface is meagre through aquation, its inner formation is difficult to be hydrolyzed " core " with aquation.Cause like this mobility of mortar and workability poor, in order to obtain suitable workability in construction process, not only to strengthen water consumption, but also the admixtures such as lime putty, micro foam agent, lime king or mortar king will be mixed to improve mobility and the workability of mortar in mortar.
But more or less all there is certain defect in existing admixture, as: lime putty is mixed and is being plastered, whitewashing or in masonry mortar, easily occur the quality problems such as snuff, be full of cracks, hollowing after for some time; And micro foam agent, lime king, mortar king mix in mortar and easily produce bubble, there is crafters in mortar, reduce the intensity of mortar.Therefore, a kind of new technical scheme is needed to solve above-mentioned technical problem.
Summary of the invention
The object of this invention is to provide a kind of mortar toughener, this toughener formulating of recipe is novel, and it can the mobility of reinforced mortar, workability, frost resistance and impermeability, also can reduce water consumption simultaneously, improve intensity and the weather resistance of mortar.
The technical solution used in the present invention is:
A kind of mortar toughener, its each components based on weight percentage is:
Further, described anion surfactant is K12.
Further, described cement water reducing agent is methylene radical dimethyl sodium dinaphthalenesulfonate polymkeric substance.
Further, described air entrapment agent is the mixture of triterpenoid saponin or triterpenoid saponin or triterpenoid saponin and triterpenoid saponin arbitrary proportion.
Owing to being rich in negatively charged ion in the present invention, after it mixes together with cement, Sha Heshui, cement granules adsorpting anion and with negative electricity immediately, make the water polarization around cement granules, same sex ion repels each other, thus prevent the close to each other of cement granules adjacent ions, play dispersion and the effect be separated, improve absorption and the diffusibility of cement granules, thus inhibit aggregate in sand-cement slurry to produce, increase the contact area of cement granules and water, cement granules is fully hydrolyzed and aquation.Simultaneously, cement granules is in the process of diffusion, the free-water that aggregate surrounds is discharged, sand-cement slurry becomes collosol structure by netted coherent structure, make mortar have good water-retentivity and viscosity, thus improve the mobility of mortar, workability, intensity, weather resistance, frost resistance and impermeability.
Advantage of the present invention is: the present invention is as a kind of hydrophilic surfactant's material, it has the effect of thickening, thickening, dispersion and modification to sand-cement slurry, it not only can reduce the consumption of cement and water, reduce the thermal source of mortar, the temperature being convenient to mortar controls and construction, save building cost, and the mobility of sand-cement slurry, workability, intensity, weather resistance, frost resistance and impermeability can be improved.
Embodiment
Embodiment 1
A kind of mortar toughener, its each components based on weight percentage is: Vltra tears 10%, K1210%, methylene radical dimethyl sodium dinaphthalenesulfonate polymkeric substance 20%, fat alcohol polyethylene ether sodium sulfate 20%, OP-1020%, triterpenoid saponin 10%, triterpenoid saponin 10%.
Namely mortar toughener finished product is obtained after above-mentioned each component mixes.
This product using method: first add in stirrer by sand, mortar toughener and cement are added in the lump in stirrer subsequently after stirring 1-2 minute and add water, and then stir 7-10 minute, the incorporation of mortar toughener only accounts for 0.02% of cement weight.In whipping process, mortar toughener can make cement be hydrolyzed completely and aquation, and can discharge gas in mortar, reduces the generation of crafters in mortar, the intensity of reinforced mortar and weather resistance.
