The technical schemes such as material ".These many technical schemes have a common and respective advantage, common advantage be price be all far below into
" cementitious capillary waterproofing material " of mouth, but there is also common shortcoming, that is, the Matter Composition sample number for constituting is more, so
Its price is reduced again has any problem;In addition, the performance of its waterproof still has gap with " the cement-base infiltration crystallization type water-proof material " of import.
The content of the invention
The invention aims to overcome the deficiencies in the prior art, there is provided a kind of cementitious capillary waterproofing material,
The Matter Composition that it is constituted is simple, and several Matter Composition prices are low, so the waterproof material low manufacture cost of composition, easily pushes away
Extensively;In addition, water resistance is greatly improved;Further, either composition is constituted, is used for, and can meet national green
The related request of environment-friendly building materials product.
Above-mentioned goal of the invention is achieved through the following technical solutions, a kind of cementitious capillary waterproofing material,
It is characterized by:The waterproof material is mixed by the component of following weight proportion:56~62 parts of cement, 27 parts of quartz sand~
33 parts, 7~11 parts of complex catalyst, 1~3 part of zeolite waterproofing agent;Described complex catalyst by following weight proportion component
It is mixed and modified to form:87~75 parts of zeolite powder, 5~10 parts of lithium metasilicate, 5~10 parts of gluconate, isobutyl triethoxy silane
3~5 parts.
Preferably, described zeolite waterproofing agent is modified zeolite, aliphatic acid, the surface-modified treatment of silane Composite Milk again
Rubber powder, cellulose ether are formed.
Preferably, described gluconate be one kind in calcium gluconae, sodium gluconate, magnesium gluconate or
More than two kinds.
Beneficial effects of the present invention are as follows:Because this waterproof material is only prevented with cement, quartz sand, complex catalyst, zeolite
Four kinds of Matter Compositions of aqua, and four kinds of Matter Composition prices are all very limited, so low manufacture cost, easily promotes;And four kinds of things
Zeolite waterproofing agent in matter composition, with grade natural zeolite high as primary raw material, using its distinctive adsorptivity, ion exchange
Property, acid resistance, alkali resistance, by the way that activation, roasting, surface be modified etc., series of process processes forms, and is to collect closely knit, bleed, hate
The water-proofing anticracking such as water, secondary crystallization, microdilatancy, decrement mechanism is in the multifunctional mortar of one.Its water-proof mechanism:Modified treatment
Zeolite crystallite afterwards can improve the uniformity of cement mixture, workability, promote hydrated cementitious and form hydrophobic adsorption layer and not
Dissolubility colloidal substance, filling concrete capillary slit prevents water translocation, reduces water absorption, improves hydrophobicity and impermeability.Due to
Zeolite is rich in SiO2, activity A12O3And various trace elements, the hydration reaction of continuous uniform can be carried out with cement, generation has
The calcium sulphoaluminate of micro-expansibility is entringite, can play a part of compensation and shrink;Due to the zeolite through silane surface modified treatment,
The surface tension of Behavior of Hardened Cement Paste can be significantly reduced, reduces the negative pressure produced after cement pore dehydration, so as to reduce the dry of Behavior of Hardened Cement Paste
Contracting.Activated silica and activated aluminum in zeolite, can participate in Binder Materials hydration and hardening, generate hydrated calcium silicate and calcium aluminate, increase
Gelled product, improvement gathers materials cementing with Binder Materials, increases density, improves compression strength.Simultaneously can also be with hydrated cementitious
There is secondary response in the calcium hydroxide and gypsum for producing afterwards, generation hydrophobicity crystalline material blocks pore, seam, further improves
Density and crack self-healing.The special porous rack-like structure of zeolite and pozzolanic activity, moreover it is possible to reduce hydration heat of cement and
Suppress alkali-aggregate reaction, make waterproof effect that there are long-time stability.Cementitious capillary waterproofing material of the invention is adopted
With complexing-precipitation reaction mechanism, the chemism that can be complexed with calcium ion is there is in cementitious capillary waterproofing material
Material-complex catalyst, under the collective effect of concentration and pressure differential, complex catalyst is penetrated into concrete by carrier of water
Portion, when by calcium hydroxide high concentration region, with the calcium ion complexing that ionizes out in concrete, forms soluble in water unstable
Calcium complex.Complex compound spreads with water in concrete pore, runs into activity unhydrated cement, cement gel body higher
Deng active chemistry will be replaced by more stable silicate, aluminate etc., and crystallization, precipitation reaction occur, so as to by hydrogen-oxygen
Change calcium and be converted into the crystalline compounds with some strength, be filled in crack and capillary porosity in concrete.And activity chemistry
Material then becomes free radical again, and continuation is internally migrated with water.When concrete is in drying regime, it is situated between due to lacking diffusion
Matter, active material is in " dormancy " state, and when there is water to penetrate into, active material will be activated once again, and catalysis occurs new crystallization
Reaction, makes structurally waterproof.Therefore, such material has permanent waterproof characteristic.
Description more than shows that the present invention can be summarized as follows with the difference of prior art:
Complex catalyst is different.The present invention using natural zeolite physicochemical property, mainly adsorptivity and ion exchangeable is by silicon
Sour lithium, gluconate, isobutyl triethoxy silane absorption wrap up zeolite microparticles surface, structure in zeolite nanoaperture
Into core component complex catalyst.
The compositing formula of material is different.The most basic material composition of cement based penetration crystallization type water proofing paint is by silicate
Cement, catalyst, quartz sand, silicon ash, siliceous miberal powder, water-loss reducer composition.But because its early stage impermeability pressure is not high, and crystallize
Process time is more long, in order to coating hardening can meet water-tight requirement after improving the early stage impermeability of material and constructing, only
Waterproof requirement could be accelerated by combination of materials technology, therefore this technology has been further added by zeolite on the basis of existing conventional techniques
Waterproofing agent component, significantly improves the early stage impermeability and water proofing property of material.The present invention is not only suitable for concrete structure upstream face
First waterproof, waterproofing and leakage-stopping is administered after being also suitable for concrete structure back side.
Because above-mentioned reason, this waterproof material has as described above than general cement-base infiltration crystallization:Increased
