Embodiment
Technical solution of the present invention is illustrated to be clearer, the skill below in conjunction with embodiment to the present invention
Art scheme is further elaborated：
In the specific embodiment of the present invention, the present invention provides a kind of gravity flowing levelling mortar, it includes following
The component of mass percent：Inorganic gel agent 35~42%, filler 15~20%, sand 35~45%, redispersable latex powder 1
~3%, cellulose ether 0.05~0.1%, auxiliary rheological agents 0.03~0.05%.
The gravity flowing levelling mortar of the present invention is in inorganic gel materials, filler, sand, redispersable latex powder, cellulose ether
On the basis of add auxiliary rheological agents.Auxiliary rheological agents were the key component of paint and printing ink paint originally, fluid can be controlled to produce
The delicate nature and feature of product, will be as water " stream to flow away " without these media.Paint will four in coating process
Place splashes, and covering power diminishes, and the pot-life can also shorten, and can use the mobility of auxiliary rheological agents adjustment paint, reduce
The drippage occurred during roller coat or brushing and splashing, paint viscosity is quick and controllably increases, so as to improve anti-sag
Property, coating transport or store during, auxiliary rheological agents can prevent formula in pigment sedimentation, it is ensured that final products it is consistent
Property, reaches the balance of rationality between durability and good coating characteristics.
The present invention is made by adding the auxiliary rheological agents with effects such as suspension, anti-settling, anti-sags in gravity flowing levelling mortar
Gravity flowing levelling mortar in the case where water consumption is excessive still can retention property it is constant because when gravity flowing levelling mortar water consumption it is excessive
When, the larger filler of density, sand can settle, so causing gravity flowing levelling mortar to produce lamination, i.e. surface is more
Remaining water, bottom are the larger filler of density, sand, such the result is that the surface bleeding of gravity flowing levelling mortar, without intensity, reaches
Less than the requirement of subsequent construction, and auxiliary rheological agents have suspension, the effect of anti-settling, after the addition of auxiliary rheological agents, Self-leveling sand
The larger filler of slurry Midst density, sand will be suspended in mortar, will not be settled so that levels energy in gravity flowing levelling mortar
Enough it is evenly distributed.The addition of auxiliary rheological agents, it is ensured that gravity flowing levelling mortar can keep equal in certain relative broad range water consumption
The effect of even distribution, the gravity flowing levelling mortar of this wide scope water consumption greatly improve the serious forgiveness of worker in the construction process, are
Work progress provides great convenience.
Wherein, the auxiliary rheological agents are pressed by any two kinds in modified alta-mud, modified montmorillonite used, guar gum and xanthans
It is 1~2 according to mass ratio:1 ratio composition.The auxiliary rheological agents of said components and proportioning play the role of suspension, anti-settling, not only
Make gravity flowing levelling mortar in the case where water consumption is few, by increasing capacitance it is possible to increase fluidity, improves levelability, and excessive even in water consumption
In the case of will not produce excreting water phenomenon, i.e., gravity flowing levelling mortar can still keep the same performance wider with the range of water.
The inorganic gel agent is made of the component of following mass percent：Common silicate cement 20~25%, aluminate
Cement 11~12%, gypsum 4~5%.The effect of Portland cement is to provide the middle and later periods intensity of mortar, aluminate early stage
Gain in strength is fast, and mortar can be made hard soon, and so as to the progress of subsequent construction, effect of the gypsum in gravity flowing levelling mortar mainly has
Help make mortar expansion, prevent situation about cracking after construction.
The common silicate cement strength grade is P.O42.5, and aluminate cement is one in sulphur aluminium cement, high alumina cement
Kind or two kinds, gypsum is anhydrous gypsum, semi-hydrated gypsum, the one or more in natural dihydrate gypsum.
The filler is one kind in heavy calcium carbonate powder, talcum powder, silicon ash, zeolite powder, flyash or metakaolin
Or it is a variety of, the fineness of filler is 200~400 mesh.The filler can improve the workability and compaction rate of mortar, be conducive to carry
Strong mechanical performance, can also improve the mobility, stability and later strength of mortar.
The sand one or both of for washed-out sand, diamond dust or quartz sand, and the particle diameter of sand for 0~
0.236mm continuous gradings.One or both of washed-out sand, diamond dust, quartz sand mix the aggregate as cement bonding agent, energy
Effectively cubic deformation of the limitation cement when cementitious material is in aquation, and the bonding that can significantly improve gravity flowing levelling mortar is strong
Degree, increases the bending and compressive strength of mortar.
The redispersable latex powder is polyvinyl acetate, in acrylate copolymer, phenylpropyl alcohol redispersable latex powder
One or more.Redispersable latex powder can effectively form a film in levelling mortar as high molecular polymer, reduce elasticity
Modulus, the rigidity of modified cement, improves the cohesive force of mortar, increase the adhesive strength of mortar, wearability, toughness, impermeability and
Impact resistance, improving workability and reducing dry shrink also has certain effect.
The cellulose ether is one or both of hydroxypropyl methyl cellulose ether, ethoxyl methyl cellulose ether, is glued
Spend for 400~600mPa.s.The cellulose ether can assign mortar thixotropy denseness, reduce the evaporation and absorption of moisture, have
Beneficial to extension operable time, improve stability.Cellulose ether is a kind of high molecular polymer of tridimensional network, is being crosslinked
Net structure on there are many hydrophilic radicals, these groups to associate to form hydrogen bond with moisture, the substantial amounts of Free water of sticking,
Play the role of water conservation and thickening.
The gravity flowing levelling mortar of the present invention further includes the component of following mass percent：Water-reducing agent 0.1~0.15%, defoamer
0.05~0.1%, retarder 0.02~0.1%, coagulant 0.02~0.05%.Although above-mentioned auxiliary agent institute in gravity flowing levelling mortar
The ratio accounted for is very low, but the effect that each ratio performers are indispensable.
Preferably, water-reducing agent is lignosulfonates, naphthalene sulfonate, sulfamate, one kind in polycarboxylate or more
Kind, defoamer is polyethers, the one or more in organosiloxane class, phosphoric acid ester, and retarder is tartaric acid, gluconic acid
One or more in sodium, citric acid, coagulant are one or both of lithium sulfate, lithium chloride, lithium carbonate.
Wherein, the effect of above-mentioned water-reducing agent is that the fluidity of mortar can be improved under the conditions of low water binder ratio, is not being reduced
Mixing water amount is reduced in the case of mobility, improves the compaction rate of hardening of cement body structure, improves mechanical property.Defoamer
Effect be that can eliminate the bubble introduced in mortar by mechanical agitation and surfactant, so as to improve intensity, improve surface
Flatness.In addition, after bubble is eliminated, releasable a certain amount of Free water, therefore, defoamer also acts as certain diminishing
Effect.The effect of retarder is can to delay hydrated cementitious, reduces the fluidity gradual loss of gravity flowing levelling mortar, it is ensured that mortar foot
Enough operating times.The effect of wherein coagulant is can to accelerate hydrated cementitious, the early strength of mortar is improved, so as to subsequent construction
Progress.
