Description
Technical field
The invention belongs to field of waterproof materials, more particularly to a kind of single polymer cement waterproofing mortar and its preparation
Method.
Background technique
The Polymer cement materials in China market are divided into two classes at present, one kind is two-component, i.e. emulsion-type；
One kind is one-component, i.e. re-dispersible glue powder type, and the waterproof mortar of two-component has on waterproof impervious characteristic, flexility
Some superiority, but due to containing a certain amount of VOC in the liquid material of two-component, and sterilization antiseptic is dosed, have one to human body
Fixed harm, and bi-component package, transport, storage cost it is also higher.The packaging of the waterproof mortar of one-component, transport, storage
Although cost has some superiority, but universal cracking resistance anti-permeability performance will be lower than the waterproof mortar of bi-component.
Summary of the invention
Technical problem to be solved by the present invention lies in provide a kind of one-component cement water-proof that cracking resistance anti-permeability performance is excellent
Mortar and preparation method thereof, in order to achieve the above objectives, the present invention use calcium sulphoaluminate, polypropylene fibre, make the anti-drying shrinkage of waterproof layer
Ability, anti-cracking ability enhancing increase waterproof layer water resistant barrier performance by using powder defoaming agent, water-reducing agent, hydrophober
By force.
To achieve the above object, the present invention provides following schemes:
The present invention provides a kind of single polymer cement waterproofing mortar, according to parts by weight, including following component: silicic acid
It 300-400 parts of salt cement, grey calcium 3-8 parts, 450-550 parts of washed-out sand, 80-120 parts of flyash, 2-4 parts of polypropylene fibre, can be again
Rubber powder 30-50 parts of dispersion, 20-40 parts of calcium sulphoaluminate, 1.5-2.5 parts of powder defoaming agent, 0.8-1.2 parts of water-reducing agent, hydrophober 3-5
Part, 1-2 parts of hydroxypropyl methyl cellulose.
Preferably, the portland cement is mixed by Portland clinker, lime stone, granulated blast-furnace slag and gypsum
After through calcining, it is levigate made of hydraulicity gel rubber material.
Preferably, the grey calcium main component is Ca (OH)2, it is with CaCO3Natural fat lime stone as main component,
After becoming quick lime (CaO) after high-temperature calcination, then it is featured, it is partial digested, then using high speed selection by winnowing beater grinder
Made of crushing.
Preferably, the washed-out sand is the roughing sand for building that natural silica Sand is washed, is classified, as mass fraction clay content
≤ 1.0%.
Preferably, the flyash is the fine ash that catching is got off from the flue gas after coal combustion, and flyash is coal-burning power plant
The primary solids waste of discharge.
Preferably, the isotactic polypropylene that the polypropylene fibre is obtained using propylene polymerization is fine to synthesize made of raw material spinning
Dimension.
Preferably, the re-dispersible glue powder is the two of vinylacetate and tertiary ethylene carbonate or ethylene or acrylate
The copolymer of member or ternary, the modified emulsion powder obtained by spray drying, it has good redispersible, connects with water
Again lotion is dispersed into when touching, and its chemical property is identical with initial latex, minimum film formation temperature and glass transition temperature
It is lower.
Preferably, the calcium sulphoaluminate is to be given birth to calcium oxide, aluminum oxide and calcium sulfate in 1000~1250 DEG C of reactions
At being a kind of morning strong mineral.The presence of calcium sulphoaluminate can make cement in aquations such as the more C-S-H gels of aquation early formation
Product, hence it is evident that reduce Ca (OH)2Forming amount, change hardened paste in hydrated product type and matching relationship, be conducive to cement
The development of early strength, and have facilitation to the aquation of the mixing materials such as slag, flyash.Simultaneously because calcium sulphoaluminate adds
Enter, due to the complex effect of mixing material and the double action of pile up effect, keeps the strength character of complex cement a kind of more mixed than singly mixing
The cement increase rate for closing material is bigger.
Preferably, the powder defoaming agent is polysiloxanes, emulsifier, high activity polyether defoaming agent by being polymerized.
The powder defoaming agent moisture-free, the powder-product that can apply to not moisture one of works as defoaming agent, in the present invention
Application can reduce the voidage of water sand pulp layer.
Preferably, the water-reducing agent is a kind of under conditions of maintaining concrete slump to be basically unchanged, and can be reduced mix
The concrete admixture of water consumption.Water-reducing agent preferred anionic surfactant used in the present invention, such as lignosulfonates, naphthalene
Sulfonate and formaldehyde polymer etc..
Preferably, the hydrophober is silane based additive, and main component is siloxanes.
Preferably, the hydroxypropyl methyl cellulose is available from the gossypin of high purity as raw material, in alkaline item
It is etherified and obtained under part.
The present invention also provides the preparation method of the single polymer cement waterproofing mortar, the preparation method packet
It includes: weighing raw material according to the weight, the portland cement of precise is put into container, successively by grey calcium, water
Washed-out sand, fine coal ash, polypropylene fibre, re-dispersible glue powder, calcium sulphoaluminate, defoaming agent, water-reducing agent, hydrophober and hydroxypropyl first
Base cellulose is added in stirring container after mixing evenly.
The above-mentioned powder for meeting industrial requirements is packed, single polymer cement waterproofing mortar is obtained.
Compared with prior art, the present invention has the advantage that
Calcium sulphoaluminate plays compensation contraction, and polypropylene fibre plays cracking resistance, including temperature-caused shrinkage and dynamic are opened
It splits, the two calculates error with the use of dosage when reducing single use, can make the receipts of the invention for preferably resisting During Initial Stage Construction
The Dynamic cracking of contracting cracking and later period.Powder defoaming agent can reduce the hole generated by bubble in coating, and water-reducing agent can subtract
The dosage of water is stirred less, so that moisture content is waved point and the hole of generation in diminishing film forming procedure, improves the consistency of coating, hydrophober
Waterproof coating provides hydrophobic performance, and three is fine and close with the use of that can make waterproof coating, and waterproof performance is more preferably.
Cooperation of the gained single polymer cement waterproofing mortar waterproof layer of the invention because of calcium sulphoaluminate and polypropylene fibre
It uses, so that anti-drying shrinkage ability, anti-cracking ability enhance, because powder defoaming agent, water-reducing agent, hydrophober are used cooperatively, makes to prevent
The porosity of water layer is low, close structure, and hydrophobic barrier performance enhances compared with common product.
