Description
Technical field
The invention belongs to building material field, particularly a kind of microdilatancy hydrophobic polyurethane mortar compositions and preparation method thereof.
Background technology
Greatly dry-shrinkage deformed with the ordinary mortar of the material compositions such as cement, sand, breeze, impermeability, splitting resistance, corrosion-resistant, be subject to great restriction in actual applications; And adopt the polymer mortar of the material modifications such as oleic series emulsion, epoxy resin, urethane to arise at the historic moment, in practical engineering application, also illustrate remarkable performance.The emulsion modified polymer mortar of oleic series has excellent water resistance, but because the intensity of ACRYLIC EMULSION own is low, the test piece intensity obtained is lower; With polymer mortar prepared by epoxy resin or water-base epoxy, the technical indicator of reinforcing mortar can be met, but due to the easy implode of epoxy in hot environment, the reasons such as low-temperature curing difficulty, its application have also been obtained restriction.Polyurethane cement, with the workability of the wear resistance of its excellence, resistance to chemical attack, high strength, performance controllability, toughness and excellence, will have wide application space in engineer applied in the future.
Chinese patent application CN103420657A discloses the polyurethane cement adopting oiliness urethane and cement matrix to be mixed with.Although the polyurethane cement that this kind of preparation method obtains has certain advantage compared with ordinary mortar, but simultaneously because the parcel of the mineral aggregates such as oiliness polyurethane material and cement is poor, the bad dispersibility of oiliness polyurethane material, easily cause reunion in the final article, final formation stress concentration, plays negative impact to the life-span of benefiting from of integrated member on the contrary.Its preparation method adopts the preparation technology of monocomponent polyurethane first to prepare monocomponent polyurethane performed polymer, and then be uniformly mixed with the aggregate such as cement, and preparation technology is more complicated comparatively speaking, poor operability.
Chinese patent application CN104177030A discloses a kind of polyurethane epoxy sand-cement slurry and preparation method thereof, adopts substep to add the way of dual-component polyurethane two components, promotes the dispersion effect of urethane two components in mortar.Although obtain certain progress, the polyurethane material of oiliness and the parcel of inorganic materials still can not well be improved.Meanwhile, macroscopically urethane in the base dispersion to a certain extent, but from microcosmic, urethane remains to be existed in shaped component with less coacervate.
Eike Kogyo K.K. discloses the aqueous polyurethane cement composition adopting polyester polyol, isocyanic ester and the aggregate containing hydraulic mortar to be formed at the patent application CN1746128B of China.The warpage that the goods adopting said composition to obtain cause due to cure shrinkage, the phenomenon of crackle are inhibited or eliminate, and tool has greatly improved.But from prolonged application, ester bond is easily explained in the alkaline environment of cement, thus loses the performance of its excellence, has certain limitation.
No. 2000-72507, Japanese Patent Laid-Open, proposes the aqueous polyurethane cement composition containing the isocyanate prepolymer composition of isocyanate group end prepolymer be obtained by reacting containing the many alcohol of hydrophobicity such as hydraulic mortar, water, aggregate, the many alcohol of castor-oil plant oils and diisocyanate cpd.The oiliness Viscotrol C that this aqueous polyurethane cement composition adopts still exists and the drawback such as the poor compatibility of aggregate materials.
Summary of the invention
Goal of the invention: in order to overcome above-mentioned the deficiencies in the prior art, the object of the invention is to a kind of microdilatancy hydrophobic polyurethane mortar compositions and preparation method thereof.
